Nick Burkhardt

Nicholas "Nick" Burkhardt is a Grimm and police detective for the Portland Police Department. Nick did not learn about his heritage until 2011 when his powers began to manifest. Since then he has become Grimm of Portland, and thus protects the innocent from the hidden dangers around them, all the while trying to find an equilibrium between his ancestors barbaric past and his own morals and ethics.

Background
Nick moved back in with Juliette after living with Monroe while Juliette worked on regaining her memory of Nick after waking from a coma caused by Adalind Schade by being kissed by Sean Renard, whom she then became obsessed with until Rosalee Calvert made the Infatuation Cure to stop the obsession between Juliette and Renard.

He used to live with Juliette, for whom he purchased an engagement ring. The ring was not seen from the day Nick bought it, until Juliette found it while putting away some socks in Nick's chest of drawers. Nick proposed to Juliette, but she turned him down because she knew that he was keeping something from her, but not the details (Nick being a Grimm for example).

He was born in Rhinebeck, New York, and lived there until his parents were thought to have died in an automobile collision in 1994 when Nick was twelve years old. The collision was secretly engineered by Soledad Marquesa, Hans Roth, Ian Flynn, and Akira Kimura to acquire the Coins of Zakynthos. Nick later discovered his mother, Kelly Burkhardt, had secretly survived  the attempt on her life, but had run to keep Nick safe from her many enemies.

Nick was raised by his Aunt Marie after the apparent death of his parents. Unknown to Nick, until a visit by Aunt Marie in 2011, he is the descendant of a long line of human warriors, who protect mankind from rogue Wesen, creatures that are not completely human, but that can appear human. While many Wesen live in peace with the humans around them, some let their wild natures get the better of them, and become violent, and it is up to a Grimm to stop this. The best known of Nick's ancestors are the Brothers Grimm, who wrote a book of fairy tales to help warn humans, especially children of the potential dangers of the world.

Nick doesn't know German, Spanish, Latin, or Japanese, but he does know a few Swedish words, like "sword" and "shield" (Grimm: The Warlock Issue 1).

On the day he meant to propose to his girlfriend Juliette Silverton, Nick's family inheritance, (the ability to see the true forms of Wesen when they get mad or excited.) manifests itself. He first witnessed a young lady turn into a Hexenbiest and then a criminal at the precinct.

He was then called to the scene of a murder with his partner and friend Hank Griffin. The murder looks a lot like the supposed bobcat attack nearby, except that there were shoe prints leaving the scene. He then goes home for the evening.

He returns to his house to find his dying aunt Marie Kessler visiting. Marie asks if Nick has been seeing unusual things, to which he admits that he has. She tells him that he is one of the last surviving members of the Grimm-family and that the creatures about which the Brothers Grimm wrote are real. Aunt Marie also tells Nick that he can not marry Juliette, as it is too dangerous.

Shortly after this, Marie is attacked by Hulda of the Reapers. Marie fights back, and Nick eventually kills Hulda with his service weapon. Before losing consciousness, she gives Nick an odd-looking key, telling him to never lose it and guard it with his life. She says “they’ll” be looking for it.

While in the hospital, Aunt Marie tells Nick that their family has an ability to see what no one else can. She says that there are creatures disguised as humans, and that when they lose control they can't remain hidden behind their disguise, and that Marie and Nick see them for what they truly are. She then tells him about her trailer, which holds centuries of collected information about various creatures throughout the world and their traits and weaknesses, along with weapons, and herbs that can help Nick do his job as a Grimm.

Back at the precinct, he deciphers the wording on Hulda's Scythe, which turns out to be "Reapers of the Grimms".

He has an odd dream later that night and goes to check the trailer, where inside he finds Marie's Book showing him some of the things he has been seeing, along with some others he has not encountered, yet. The next morning he finds out that Marie has slipped into a coma.

Back at the precinct, Nick and Hank are called about a missing girl. The last time she was seen, she was reported to have been wearing purple leggings and a red sweatshirt. Nick then realizes that the young woman that was found torn to pieces also wore a red sweatshirt. Nick and Hank then decide to follow the route that the girl would have taken to get to her grandfather's house. When they get to a park, Hank comments that when he was little, he didn't always follow the route his mother told him to, but rather took a shortcut. They decide to cut through the park like Hank says the girl might have chosen and find a trail through the woods that the little girl may possibly have used as a shortcut. Hank finds the little girl's backpack to the side of the path, and they find the same boot print that was found at the young woman's murder scene from the other day. They follow the boot prints down the trail to a street where Nick sees a man at his mailbox, whose face changes as the looks at a couple of children passing by. Nick runs down and tackles the man/creature to the ground.

At the precinct, Hank tells Nick that the man (named Monroe) was clean and that they couldn't keep him there. Nick however is not so convinced and stays in his trailer well into the night searching for answers. He finds a page that shows the creature he had seen Monroe woge into, and decides to pay him another visit.

After seeing Monroe mark his territory, he continues to try to spy on him. When Monroe goes back into his house however he woges into his wolf form and jumps through the window next to Nick tackling him to the ground. Monroe then tells Nick that he should not have come back, then changes back into human form. Laughing, he tells Nick they should go grab a beer.

Inside, Monroe says that he is surprised to actually meet a Grimm, and says that since he was little, he had been told stories of Grimms that would scare him. Monroe then surprised Nick by knowing about the book he has. Monroe then tells him that he knows that the Grimms have been observing his kind for hundreds of years. He then says that he is a reformed Blutbad and does no longer kill. Nick asks Monroe if he will help him find the little girl, and Monroe reluctantly agrees.

As they follow the little girl's trail, Monroe picks up the scent of a Blutbad and the two follow that to a small cabin in the woods. Monroe then tells Nick how to take out a Blutbad, and leaves him some wolfsbane to hide his scent. He then has to leave Nick alone, as the proximity of another Blutbad was starting to affect him.

Nick then calls for back-up, and Hank soon arrives. He tells Hank to use the wolfsbane, and then the two approach the house. The owner lets them inside and the two detectives question him. However they find nothing to connect him to Robin. Right after they leave the house, Hank realizes that the man had been singing the tune the murdered girl's mp3 player had still been playing when they found it at the scene. The two turn around and storm the house, where the man is waiting and attacks them in Blutbad form. He then tries to run, and the two shoot him. He dies before he can tell him where the girl is however.

While continuing to search the house in desperation, Nick notices that water on the floor from a vase that fell during the fighting had run down between the floor boards and disappeared. Nick pulls up the rug and finds the handle to a hidden door, leading to the basement where the little girl was being kept.

Nick then returns to the hospital to see his comatose aunt. While there, he sees a woman in a lab coat coming to give her an injection. He recognizes her as the Hexenbiest he had seen before and stops her from injecting his aunt. In the struggle, she injects him with the contents of the syringe and the last thing he sees before blacking out is her changing into a Hexenbiest.

Nick is being checked out at the hospital for the injection he had received from the young woman. The doctor concludes that Nick had been injected with the neurotoxin PhTx3. He then explains to Nick that if more venom had been injected it could have paralyzed the lungs. Nick meets up with Hank in the hallway and reassures him that he is fine. He then goes to check on his aunt, but the doctor says that she is not stable.

Back at the station, Nick, Hank and Renard review the security tapes from the hospital. Sadly, they are unable to get a clear view of the attacker. Nick and Hank are then called to look into a complaint that a woman's boyfriend was attacked.

Nick and Hank go with the woman to the place where her boyfriend was supposedly attacked. On arrival, they find Wu and several other officers at the scene. They are then told that the owners of the house, Frank and Diane Rabe had called to complain about a break-in. The two detectives examine the premises and learn that at least two people had entered. Nick and Hank then surmise that the boyfriend is probably at home, sleeping off the alcohol.

Back at the station, Gilda admits to having been in the house but claims to know nothing about Rocky's whereabouts. Marie then calls Nick and says she must speak to him immediately.

At the hospital, Marie explains that there must be more Reapers in the area and that they are part of a secret organization dedicated to killing Grimms. Nick's aunt reveals that there are other Grimms but that she does not have contact with them. Marie then cautions him not to let anyone find the trailer.

As Nick and Hank return to the Rabe Home, they almost collide with three young men on motorcycles that they learn are Barry Rabe, T. B. Colbert and Jason Colbert. The detectives tell them that they have identified the couple who broke into the house. When questioned about having been home, Nick sees Barry briefly woge into a bear-like form. Frank Rabe then tells Nick and Hank they can contact him at his law firm if they want to talk more.

Later that night, Nick dreams that he is in the trailer. His aunt Marie then comes in, pulls a knife from a nearby cabinet, and stabs him in the hand with it. Awakened by the dream, he goes out to the trailer and opens the cabinet. Inside is a bear claw similar to one he had seen at the Rabe residence.

Nick then goes to see Monroe, who says that the Wesen he saw was a Jägerbar. He also tells Nick that the claw was used in an ancient ritual called a Roh-hatz to disembowel victims. He then goes to his aunt, who tells him that the Roh-hatz will only occur at sundown.

Back at the station, Nick finds out that Barry had lied about not being at his house. He is then told that Gilda made bail and went to Rocky's to get a gun, saying "I will get Rocky back". Renard tells Nick that he had to pull police protection from Marie, so Nick calls Monroe and asks him to watch Marie for him.

Nick arrives back at the Rabe house and questions them as Grimm to Wesen about what happened. Frank seems surprised that his wife was having Barry participate in a Roh-hatz and agrees to help Nick.

Nick and Frank arrive at the cave where Gilda and Rocky had been hidden, but find them and the young Jägerbars already gone. Nick and Frank arrive and interrupt the chase, helping to get Gilda and Rocky out of there. A fully woged Diane Rabe then arrives from the opposite direction and accidentally falls into a spiked pit.

Diane Rabe is taken away in an ambulance while Barry Rabe, the Colberts, Gilda and Rocky are arrested with the assistance of Sergeant Wu. Nick then gets a call from Monroe saying he had taken out two men who had went after Marie, but that he is not sure if he got them all.

When Nick arrives at the hospital, he sees Marie kill a fake priest and then she dies in his arms. He later looks over her grave with Juliette at his side.

Nick is called to the scene of a murder on a streetcar. The victim had been in the streetcar when a flash mob had started up and by the time it stopped she had been found dead. When Nick examines the victim's (Serena Dunbrook) corpse, he finds a puncture wound like she had been injected with something. The Medical Examiner states that the victim had died from anaphylactic shock.

At the station, Nick, Hank and Wu review the security footage from the streetcar. Captain Renard tells the detectives he wants the situation resolved because of the impact on public opinion. Nick then asks Wu to publish a request for people present when the flash mob was occurring to come forward.

The two detectives then go to the law firm where Selena had worked, and talk with Harrison Berman and Camilla Gotleib. Berman disclaims any knowledge of what might have made Serena a target, but grants full access to records to assist in the investigation.

They then go meet with professor Elliot Spinella, who tells them that the toxin that killed Serena was natural, but did not match any know source.

Nick and Hank return to the station where Wu tells them that twenty-two members of the flash mob have come to the station and that Captain Renard is showing interest in the case. Nick and Hank then interview a number of participants of the flash mob. All, oddly. explain their participation using exactly the same words. Nick's interrogation of Doug Shellow becomes contentious and Doug woges into a bee-like creature. Hank provides an update about the case; while he is speaking, Doug woges again and John Coleman, another member of the mob, woges.

Nick and Hank follow Doug Shellow to an abandoned paper mill. They see him meet with John Coleman and a woman they do not recognize. Then, without warning, the two are surrounded by a swarm of bees. Nick and Hank seek shelter in an old office. They are attempting to fill all the openings when the bees disperse as suddenly as they swarmed. Hank suffers multiple stings from the ordeal.

Nick drives to Forest Hills Storage, where he keeps Marie's Trailer. He researches bees, which he learns are called Mellifers. Their mortal enemies are Hexenbiests, which he learns have a birthmark under their tongues for identification. Nick then calls Monroe, who meets him at the paper mill.

Monroe explains to Nick that mellifers are the news-relays of the Wesen population. Monroe follows a scent to an office in the mill where Nick finds an envelope addressed to Melissa Wincroft. They go to her mansion through an open door and find large hives upstairs.

The next morning, Hank arrives and Nick tells him what he had found out. Serena had been an attorney for a company that acquired the paper mill in a hostile takeover. Melissa Wincroft had been the owner of the mill, while Doug Shellow and John Coleman had been two of her employees. While the detectives are talking, a uniformed officer tells them that Sergeant Wu had called to say that there had been another flash mob murder.

Nick and Hank respond to the scene and learn that the second victim is Camilla Gotleib. Nick then realizes that a third attorney, Adalind Schade, had been working on the paper mill case. He has her taken into protective custody. When Nick arrives at the police station, he discovers that Adalind is the Hexenbiest he saw right after he bought Juliette's ring and the one who had tried to kill Marie. Nick goes to the Medical Examiner Office and asks Dr. Harper to show him the two murdered women's tongues, and they both have the Hexenbiest birthmark like he suspected. Nick and Hank are assigned to protect Adalind, but while they are taking a break, Renard tells Adalind he will protect her.

Nick and Hank decide to force Doug Shellow's hand. Nick resumes the interview with Doug, when Hank abruptly calls him out of the room. Nick complies, leaving Doug's smart phone behind. Doug then uses the phone to alert Melissa of what is happening.

Wu and a policewoman go to Adalind's apartment as bait for Melissa, while Nick and Hank go to a hotel with Adalind. However, Melissa Wincroft sends the bees from her hive in search of the Hexenbiest and they find the real Adalind. While the detectives are fighting off the swarms of bees, Adalind slips away. After getting rid of the bees, Nick chases Adalind into an equipment room in the basement of the building; there he finds Melissa, who says she has to kill Adalind and that she is on Nick's side, waiting. Thousands of bees are flying around the room. When Melissa tries to kill Adalind with a Mellifer Stinger, Nick shoots Melissa. Melissa warns that, "He's coming for you," and dies; all the bees then fall to the floor, apparently also dead.

That night, Nick feels conflicted on if he made the right call, even though Juliette tries to assure him that he did. She then says she is cold, so he gets up to close the window. A bee then stings his hand.

Nick and Hank arrive on the scene where a young woman has been hit with a car and killed. After the CSI is done examining the body, the detectives observe that the barefooted woman has no injuries to her feet but does have glass in cuts on her arm.

Back at the precinct, the two detectives confer with the medical examiner, Doctor Harper, who tells them that the victim did not die from being hit with the car, but rather by asphyxiation. Using her fingerprints, Hank identifies the young woman as Faith Collins.

Nick and Hank go and interview Faith's husband, Roy Collins, who has a record of spouse abuse. Roy admits to having argued with Faith, but denies any wrongdoing. He says she left their home that night but that he waited for her to return as she had always returned in the past.

Back at the precinct, Nick and Hank check Faith's page on a social networking site and find a picture taken in the garden of the Bramble Haus, a bed and breakfast.

They go there and talk to the owner/operator, Billy Capra, just as a young man and woman are checking out. Capra says he showed a room to Faith but that she did not stay. He offers to show them his garden and they accept, once in the garden, Hank inadvertently steps on a kills a toad. Capra gets upset saying that the toad is an endangered species and picks up the remains. Nick then sees Capra woge into a goat-like form he does not recognize.

Nick and Hank decide that they have to look into Billy Capra's background; as they enter the squad room, they pass the reaper.

Nick goes to Marie's Trailer and looks for the goat-like creature, which he finds out is called a Ziegevolk. He then goes to ask Monroe some questions.

Monroe tells him that Ziegevolk exert a special pheromone that makes woman fall in love with them. The ones that eat toads are herders, there pheromones are more powerful and can even make men like them. This latter causes Nick to wonder why people are attracted to each-other.

Back at the precinct, Nick tells Hank that the glass pieces in Faith's arms were from regular window glass and that she must have broken a window right before she died. They then discover that three women from out of town have disappeared in Portland since Capra arrived and bought the Bramble Haus. They also find that a similar situation has occurred in three other cities in the U.S.

Nick and Hank decide to stake-out Capra's bed-and-breakfast, and Hank installs a tracking device on Capra's car. Sadly, Capra decides to walk when he leaves his inn and Nick is forced to follow him while Hank checks out the Inn. As Nick follows Capra, he sees him eat a frog, and then go into a bar. Nick then calls Monroe and asks if he will spy on Capra in the bar, to which Monroe agrees. Monroe calls him a little while later saying that Capra was leaving the bar, and that he had been talking to a young woman.

Nick is arrives back at the Inn slightly before Capra and is worried that Hank hadn't answered. He goes downstairs and seeing Hank collapsed he turns off the gas, and tries to help his friend. Billy then shuts and locks the door leaving them inside and turns back on the gas.

Nick and Hank manage to get out but have lost Billy. Hank then remembers about the GPS that they had planted on Billy's car. Luckily, it works and they track him to a park. Once there, they spot Billy and Lisa and call for Billy to halt, that he was under arrest. Billy woges into a Ziegevolk and runs for it, until he is hit by a car. He survives and is taken to prison.

Nick gets called to the Von Hamelin Music Institute where the dead body of Paul Lawson has been found eaten away in his (Lawson's) car. When the detective gives the order to open the car, a swarm of rats spill out. After a further search of the perimeter, several rat cages are found labelled "Geiger Pest Control".

Later, while interrogating the members of the quartet, Nick and Hank learn that there was a student called Roddy Geiger that was suspended a few days earlier. Sarah Jennings, however, says that Roddy wouldn't do something like that.

When the detectives arrive at the Geiger residence, they hear music which leads them to Roddy, who is playing in a shed with rats pressing up against the walls of their cages to listen.

His father, Ephram Geiger, accuses them of coming to arrest and hurt them, woging into a rat-like creature just before he tries to strike Hank for grabbing Roddy. Roddy sees that Nick is a Grimm and instantly distrusts him. He runs, but is cornered by Nick. He accuses Nick of wanting to kill him before attacking (which is stopped by Nick punching him in the face). Both Geigers are then arrested.

Back at the precinct, Ephram Geiger says that he was in the mountains during the time of attack while also saying the cages were stolen and that the students at the school never let his son forget their lack of wealth and that they frequently got in quarrels. During Roddy's interrogation, Nick and Hank find out that he was suspended for attacking Carter and Trey. He claims, however, that It was self-defense. He also admits that he was at the rave the night before and says that one person can alibi him. That person reveals that Roddy is DJ Retchid Kat and Roddy goes free though his dad has to stay.

Doctor Harper calls the two detectives and tells them that Dr. Lawson did not die of the rats; he died of a heart attack. Harper also shows green and red nylon fibers that she found in a rat's stomach which could have come from the car.

Nick goes to Monroe who tells him about the rat-like creature, which is called a Reinigen. He says that they are at the bottom of the food chain and Nick shows that he already knows a bit about them by saying that they're only violent when pushed to the limit. Nick then asks Monroe to talk to Roddy and convinces him to by describing Roddy's musical talent.

Nick and Hank tell Renard about the results they found with the fibers. It is discovered that Carter Brimley (a member of the quartet) drives a car of the description they're looking for and Renard grants them a search warrant. After a search of Carter's SUV (while being badgered by an indignant father), Nick and Hank find a school banner that matches the fibers as well as a rat dropping in the vehicle. They then go to Sarah's house and find a text on her phone that says that Retchid Kat would be at a warehouse on Front Street.

Nick and hank arrive at the warehouse to find one vehicle on the lot. They assume it is the kids and hurry downstairs. When the police arrive, the boys run away and Sarah is alone and being attacked by rays, so Roddy stops the music just before Hank shoots his gun upwards so that the rats will disperse. Nick then rushes to Sarah and gets the remaining rats off her.

Shortly after, the boys admit to the police that they did it, but they only meant to scare Dr. Lawson and make it seem Roddy did it. Sarah bluntly says that Roddy was better than all of them and asks them to tell Roddy she's sorry. Later, while trying to write the report, they decide to let Roddy off the hook seeing as it was doubtful anyone would believe them and no one forced the four to go down there.

Afterwards, Nick arrives home from work to find the refrigerator repairman in the middle of working. When the man stands up however, he woges out of frustration into a beaver-like creature. He realizes Nick is a Grimm and becomes scared, quickly hurrying out of the house.

Nick is called to the scene of the wreckage of Hap Lasser's home along with Hank. Later at the precinct, when he questions Hap, he later learns that Monroe is Hap's emergency contact when the former shows up to take Hap home. He later comes to visit Monroe and Hap at Monroe's house that night, and is assaulted by Hap's sister Angelina before Hap and Monroe manage to get her off of him. Later, inside the house, he narrowly avoids getting attacked by Angelina twice thanks to the efforts of Hap and Monroe. After Hap is killed, Nick is openly suspicious of Angelina being responsible for the deaths of her two brothers. That is, until he learns about Lt. Orson being a Bauerschwein and about the feud between Blutbaden and Bauerschwein. He later confronts Orson at the precinct, where Orson woges and learns that Nick is a Grimm. Later that night, he comes to Orson's house right as the Bauerschwein is in the midst of a mud bath. After a brief confrontation about the matter of how Orson killed Hap and Rolf Lasser and the matter of Orson's own brothers being killed by Angelina, Angelina arrives, and she and Lt. Orson get into a vicious fight. Orson demands for Nick to help him kill Angelina, but Nick instead briefly subdues her by knocking her in the sensitive spot on her back. This distracts Angelina long enough for Orson to shoot her in the back, and she flees from the scene bleeding. After this, Nick is there when Orson is taken to the hospital, and it is presumable that he was forced to arrest Orson for the murders of the two Blutbaden he killed.

Nick and Hank are called to an marijuana plantation where the grower has been found dead. While looking around Nick sees what he thinks is a Wesen, but he is not sure. He does, however, find hair and blood traces which he takes back to the lab for processing. The traces prove to come from a child, Holly Clark, who went missing nine years earlier. Based on this information and his glimpse earlier, Nick decides to enlist Monroe's help in searching the forest. Monroe confirms that there is a Blutbad in the area and they track her. They find that Holly has been living in a hunting hide located up a tree. Holly was injured by Delmar Blake, so Nick leaves her with Monroe while he goes to call for an ambulance. While in the hide, Nick noticed the name Addison on some of the items, which he reports to Hank, allowing Hank to arrests James Addison. When he returns to the hide, he finds that the Delmar's brothers are holding Monroe at gunpoint. In the ensuing fight Nick shoots Roland while Holly strangles Micah with her hair. Once Holly has been to hospital Nick takes her back to her adoptive mother.

In the case of the murder of Logan Patterson, Nick is examining another area of the case while Hank and Wu are at Patterson's house. Later on, he and Hank visit Monroe to ask about the watch found on Vince Chilton's amputated arm. When he later learns about Oleg Stark, he looks through the Grimm diaries in the trailer in an attempt to find out what sort of Wesen Oleg might be. He looks through the entries for the Mordstier, Rißfleisch, and the Siegbarste before he gives up for the night. He is later at the scene of the car explosion set off by Oleg, who stands not to far behind Nick before fleeing right as Nick turns his head in sensing that someone's behind him. Later that night, he is brutally assaulted by Oleg Stark in the Siegbarste's murderous attempt at getting Nick to reveal where Hank is. When Oleg realizes that Nick is a Grimm, he is ready to kill Nick until Juliette arrives and saves Nick's life by splashing Stark in the face with boiling water. Nick is hospitalized as a result, and he learns about Siegbarstes and that Oleg Stark is one from Monroe when he is visited by Monroe. After Monroe explains about Siegbarstes, Nick realizes that the weapon and poison needed to kill Oleg Stark is inside the trailer, and in a leap of faith, tells Monroe about the trailer and gives him the keys to it before assigning him to obtain the needed items from it and get them to Hank so that he can successfully deal with Stark when he encounters him.

Nick is one of the officers called to the scene when Leonard Drake's body is found in the trash compactor of the trash truck. Later on after talking with the owner of the apartment building where Leonard lived, he and Hank talk about the matter with Leonard's girlfriend, Natalie Haverstraw, who tells them about how Leonard had gotten into a drunken abusive rage at her when she tried to leave him the previous night and about how their fellow tenants, Martin Burgess and Mason Snyder intervened on her behalf.

Upon learning of these two other witnesses of the argument before Leonard's death, Nick and Hank visit the junk shop that Marty runs. Nick is at first unsure of why Hank appears nervous inside the junk shop; that is, until Hank explains how he sees all the junk as remnants of lives that people have to give up. When they talk to Martin afterward, Martin tells about how he had asked Natalie if she was okay when he'd overheard what was going on between her and Leonard. He had gotten yelled at to go away by Leonard, and had slunk back into his apartment when Mason Snyder arrived. He finishes off by saying that he felt guilty for not trying to do more to help Natalie. Over the course of this conversation, Nick sees Martin morph into a mouse-like creature.

Next the two detectives visit Mason Snyder at his law firm. Over the course of the discussion about the argument that he and Martin intervened in between Leonard and Natalie, Mason's story also matches what Martin and Natalie said. However, soon afterward Mason is forced to stop the conversation to answer the phone when it starts to ring. As he angrily talks to the opposing lawyer in a case he's working on, Mason morphs into a snake-like creature. Unbeknownst to him, Nick sees this transformation. After Mason hangs up the phone, reverts back to human form, and asks if there's anything that needed to be discussed, Nick and Hank say that there isn't and leave.

That night Nick calls Monroe over to his house to discuss the two new creatures that Nick has seen. After Nick explains about the case and the two creatures, Monroe doesn't take long to identify Martin as a Mauzhertz and Mason as a Lausenschlange. Also according to Monroe, while Mauzhertzen tend to be extremely meek and cowardly, and not the fighting type, Lausenschlange like Mason are not above killing, or even eating humans. After this matter is discussed, Monroe leaves to get some sleep since he has an appointment the next day.

After Monroe leaves, Nick does some research in the trailer and the information in the books matches what Monroe has told him. Before long, he decides that he has possibly found his top suspect of the case in Mason Snyder.

However, Nick soon begins to wonder if there's more to Martin than meets the eye when he is called to the scene of the murder of a mechanic whose last customer before his death just happened to be Martin. This possibility is further supported by how the mechanic, like Leonard Drake, wasn't the nicest of people.

Upon learning about these two connections against Martin, Nick and Hank decide to test Martin's alibi of being in his apartment at the time of Leonard's death by asking Martin's father, whom Martin had said could alibi for him. However, when they arrive at the apartment, they find that the apartment is crawling with all manner of hoarded possessions, and also that, more disturbingly, Martin's father is lying on the bed, and has been that way for at least two or so days before the death of Leonard. At this point, Hank guesses that the death of his father may have set Martin off; but Nick counters that the death might have instead set Martin free.

They then go to Mason's office and find him dead, so they put an APB out on Martin. When they hear about where he was last seen, Nick deduces that he will be in his shop. The detectives arrive to find him there, and arrest him.

When Nick visits Monroe to update him on the case, he finds that he has been attacked by Reapers, and says that he'll no longer ask for his help. Monroe says that he'll continue helping and next time he'll be ready.

Nick and Hank are in the Morgue with Dr. Harper examing the body of Steven Bamford, a runaway living on the streets in Portland. Dr. Harper tells then that Steven probably drowned as result of blood extracted through two puncture marks in his neck. The only item of note on Steven's body was a pukka shell necklace. They find Steven's PO box and another street kid with the same type of necklace which leads them to Gracie and Hanson who make and sell the necklaces. From Gracie and Hanson they learn that Steven left about a month ago to work on a ranch. They last saw him at a local free clinic run by Dr. Levine. They go to the clinic, but Steven's records are no help. Nick and Hank are then called to an unusual car accident where the vehicle was transporting human organs. Just before he dies Nick sees that the driver was a Geier. Monroe tells Nick that some Wesen use human body parts as medicines and he buys some Gallenblase from Freddy Calvert in his Exotic Spice & Tea Shop. Once Nick confirms that the product is human gall bladder, Nick threatens Freddy, who reveals his supplier's name. Nick also tells Freddy that he no longer sells human body parts.When the police raid the supplier they find a lot of human organs being dried and a link back to the clinic. At the clinic the only person there is a nurse who temporarily woges into a Geier. Nick then interrogates her privately and tells her that if he has to, he'll deal with her a Grimm, not a cop. The police then raid the organ harvesting center, where Nick follows a trail of pukka shells, left by Hanson, to the operating room. Nick follows Levine and at the end of the fight she falls into a fire pit the Geiers were using to dispose of the bodies.

Nick is called to the scene of Ryan Showalter's gruesome death alongside Hank. While disgusted by the sight of the corpse, he is able to pick up the dismembered finger that Ryan bit off of his attacker, only to drop it in surprise and horror when it moves in his hand. When Hank questions him about it, Nick tells him that it moved, only for Hank to then ask him if he's going to pick it back up or whether or not he's going to have to "give him the finger" so to speak instead. Nick then heads to the trailer for research, and discovers that he may be dealing with a Spinnetod.

Later that night, Nick and Juliette are in the midst of a romantic hangout session when they notice eggs getting thrown at their window. When Nick comes out to investigate, he sees one of the two boys outside who are responsible morph into an Eisbiber. Upon seeing Nick, the two boys run away in fear. When Nick questions Juliette about what she thinks might be going on, she explains how in her childhood she and her friends had once thought that an old man with wounds on his face might be a troll, and how she and the others did all kinds of childish antics similar to what the two boys just did until she eventually learned that the old man was really not that different from any other person.

The next day Nick asks Monroe about his thoughts and Monroe explains about how due to how its been such a long time since a Grimm has been seen in Portland, Nick is the subject of great intrigue and fear among the local Wesen. At this point Nick pays a visit to the house of John Oblinger, where he also encounters Bud. Nick tells the two Eisbibers to make sure that they both stop coming to his house, and that they make sure that none of their friends come back to his house either due to how their visits may lead to more dangerous Wesen paying visits as well. The Eisbibers are quick to agree.

A second victim is discovered and fingerprints found at the scene match those found at a series of similar homicides in another state five years ago, with a link to a further series five years before that. The police are called to Sally Marcinko's school where she traded Ryan's watch for a bicycle. Nick questions Lena Marcinko and obtains her fingerprints. The prints are a match, so they return to her house to arrest her, but she is not there. The police trace her to a yacht in the Marina. Nick chases Lena around the Marina, and Lena ends up getting trapped in a fishing net before being arrested.

Nick is one of the officers to come to the scene of the murders committed by Dimitri Skontos. He is among the officers who notice the claw marks left by the skalenzahne as he was dragged away. Later on, after discussing the matter of Dimitri with his parole officer, Leo Taymor, he goes with Hank to speak to Dimitri's uncle, Gus Pappas, at the gym said uncle runs. After talking to Gus, and learning that Dimitri was close friends with fellow parolee and gym visitor, Brian Cooney, Nick and Hank speak to Cooney, a Dickfellig. Brian is at first wary of how Nick is a grimm, and woges in response, but Nick is quick to calm Brian down before things get out of hand. After a brief discussion, Brian leads the two officers to a running path where Dimitri was last seen before the night he committed the murders, and Brian then leaves at this point to go for a run.

Later the detectives receive a call from Franco telling them that Dimitri's car has been found abandoned. The car itself yields no clues, but a nearby warehouse houses what looks like a ritualistic combat arena and several medieval weapons with blood on the ground. At the precinct Captain Renard translates the Latin and explains that it refers to fighting to the death. The blood is determined to belong to Dimitri.

Nick recruits Monroe to find more information about the fight club. Monroe calls Nick to tell him that he has a meeting with a contact who'll take him to the fight. Nick goes to meet Monroe, and finds Clement about to drive away in Monroe's Volkswagen. Nick arrests him and swiftly finds the location of the fight club.

After calling for backup Nick enters the site and sees Monroe about to be killed by Dimitri. He puts his gun to Leo's head and demands that he release Monroe. Leo refuses and says that someone must die. Nick faced with the angry crowd volunteers to enter the arena himself. The crowd is excited at the prospect of seeing a Grimm fight in the arena and so Monroe is replaced by Nick. Nick defeats Dimitri, but refuses to kill him, enraging the crowd. The crowd start to invade the arena, but Nick's backup arrives and arrests the participants.

When Nick calls Juliette to tell her he's on the way home she sounds upset and Nick wonders why.

Nick Burkhardt and Hank Griffin arrive at the scene accompanied by Sgt. Wu. They go into the vault to see it robbed of all items and Sam Bertram's dead body. His face is covered with hundreds of shards of glass and metal. Unfortunately, the security camera was ripped out by the robbers. The robbery looks professional, the thieves knew what they were doing. Nick and Hank arrive at the scene of where the BMW is parked. Officer Brenner is waiting for them in his police cruiser; Nick and Hank will go inside while Brenner watches the perimeter. Hank goes in first and forces Farley Kolt to the floor. Brenner sees Soledad run out of the house and pursues them; unfortunately, he jumps a fence and disappears. Hank is upset with Brenner for letting the suspect get away, Brenner goes to his car to call for a coroner when a hand grabs him and later kills him. When Nick arrests Kolt, he sees him transform into a Steinadler.

Back at the Precinct, Nick and Hank report their findings to Captain Renard. Hank keeps talking about the guy he took down (Farley Kolt) and also mentions the coins. The Captain wants to see these coins and Hank reluctantly gives them to him. Hank wants to interrogate Kolt, but since he was rough with him earlier, the captain tells Nick to conduct the interview. Renard examines them and feels their power, he then makes a phone call to his friend in France to tell him he has found the Coins of Zakynthos. Nick suggests Hank goes home since he is angry and has had a long day. Nick then goes to interview Farley Kolt. During the interview, Farley Kolt tells Nick this is not about him being a cop, it is about being a Grimm. Kolt says the robbers robbed the store to find the Coins of Zakynthos. He tells Nick the long story about the coins; whoever possesses them has a strong influence on others. He says the coins have been safely kept until 18 years ago, when the Grimm protecting them (Nick's Parents) was killed in a car accident. The accident was in Rhinebeck, New York, the same place where Nick grew up.

Nick calls Monroe to come into the Trailer to translate some German entries. They discover Schakale, who are ruthless killers and like to eat babies, and Steinadler which are eagle-like creatures who are usually involved in the military. With Soledad Marquesa still at large, Nick and Hank go to his last known location: a hotel room. No one is there, but they do find some clothes and a suitcase. The suitcase contains a film reel with film in it and two letters concerning the coins. One letter is in German from 1943 and the other is in English from 1945. The one in English from the Office of Strategic Services is about the coins. It says that the coins are made of gold, arsenic, and mercury. They are not to be handled, they were transferred in a lead box to an allied headquarters' vault. Ten coins were thought to exist, they only found three. Hank is convinced that the coins made him act strange; he also suspects that the Captain has them in his possession. Hank decides to search for the coins himself in Renard's office. When he is searching, Nick bursts in with Farley Kolt, who was just cleared in the murder investigation. Kolt knows Soledad must be here, and he's hunting down Renard for the coins. Soledad gets into the parking garage and causes a blackout by destroying the breaker. Just as Hank, Nick and Kolt arrive, Soledad takes hold of Renard. A gun fight ensues; Nick helps Renard, but the coins and Kolt are gone. Hank manages to shoot Soledad, he lays on the floor near death. Nick asks Soledad if he killed his parents, Soledad dies before he can answer. Later, Nick finds Farley Kolt in his hotel room. He tells Farley to put the coins on the bed and leave. Just as he is about to lunge for Nick, Nick hits him hard with his gun; Farley drops the coins. Nick quickly retrieves them and tells him to forget about the coins forever. Nick goes back to the trailer where he examines the coins. Just as the coins' magic spell starts to be felt, Nick quickly puts them back in their box. He then stuffs the box behind another bigger box in the weapons cabinet. Nick loads the film he got from Kolt onto the old Kineclair projector. As he hand cranks the film, it turns out to be old video from the 1940s showing Adolf Hitler giving a speech. The Coins of Zakynthos are visible on Hitler's coat collar. Hitler then woges into a Schakal.

Nick and Hank are called to a disused factory where two burnt corpses have been found. The arson investigator Jordan Vance tells them that the fire was extremely intense to burn the bodies so badly. Later Nick, Hank and Wu are called by the building owner to say that he had been attacked by an intruder at another of his buildings. While investigating the building Wu is sprayed with an oily substance by an apparently homeless man. Nick notices that he is about to strike a light and pushes Wu out of the way, as he does so he notices the homeless man woge into a Daemonfeuer. The oily substance is analyzed and discovered to be human lipids. This leads to a DNA match for Fred Eberhart, who is missing. Fred's only know relative is his daughter Ariel Eberhart, and her contact number is a night club. Nick goes to the night club and sees several Wesen in the audience including Monroe whom he joins. The fire dancer on stage is Ariel, and once her act is finished he goes backstage to interview her. She flirts with him and reveals that she knows that he is a Grimm. She says that she does not know where her father can be found. Nick is suspicious so follows her home At her house she attacks Nick in an amorous manner causing his phone to fall to the ground. When Nick's phone rings she answers it, and pretends to Juliette (who was calling) that Nick is cheating on her. Juliette won't listen to Nick's explanation over the phone so he immediately goes home. Once home he explains the situation to Juliette, and she believes him. Next day he receives a call from Ariel saying that she may know where her father can be found, and can he return to her house that night? Nick agrees to the meeting. He then calls Juliette to let her know that he is going to Ariel's house and that Hank will be accompanying him. When Nick and Hank arrice at the house it is deserted so both return home. At home Nick follows a trail of clothing to the bedroom. He is about to get into bed when he sees that the woman in the bed has a dragon tattoo, it is Ariel, who escapes the house by spraying her lipids. Ariel calls Nick using Juliette's phone and tells him that he must fight the Daemonfeuer in his lair to save Juliette. Nick enlists Monroe's help and the two of them deduce where Fred's lair is located. Once there Nick fights and kills Fred while Monroe rescues Juliette.

Nick and Juliette are having dinner when Bud knocks on the door to tell them that they won't be troubled any more. He gives them a quilt as a gift. Juliette is confused as to how the refrigerator repairman can prevent them being troubled. Next day Nick, Hank and Wu are called to Freddy Calvert's Exotic Spice & Tea Shop to investigate his murder at the hands of two robbers. Back at the Precinct, Nick calls Freddy's next of kin, his sister Rosalee, in Seattle. Rosalee agrees to come to Portland. When she arrives Nick accompanies her to the shop, and when she woges into her Fuchsbau form realizes that he is a Grimm. Nick reassures her that he will not harm her, and did not harm her brother. She asks if anyone at the precinct knows that he is a Grimm and he replies in the negative. The lab reports that there was nothing illegal in the spice shop so Nick consults Monroe to see if there was any Wesen drugs present. Monroe does not recognise any of the scientific names, so Nick and Monroe go to the spice shop where Nick introduces Monroe to Rosalee. When Rosalee realises that Monroe is a Blutbad she is even more confused by Nick's behaviour, since, as far as she knew, Grimms and Blubad are mortal enemies. After the second break in Nick offers Rosalee police protection, but she requests Monroe as a guard and Nick agrees. Nick and Hank then go to the appartment where Clint Vickers and Joshua Hall were squating, but they escape when Hank has an hallucination of Adalind. Nick is then called to the spice shop where Wu has just collapsed. On arrival he helps Rosalee and Monroe administer the cure and then takes Wu home. Nick and Monroe decide to visit a Trauminsel where the suspects Hall and Vickers might be found. At the trauminsel Nick arrests Vickers, but Hall escapes to threaten Monroe and be hit with a brick by Rosalee before Nick can arrest him. Nick calls in to check on Wu, but he is apparently fine. He and Juliette then go to a shooting range where Nick is surprised to learn the Juliette is a very good shot.

Nick and Juliette go away for a romantic weekend, during which Nick intends to propose to Juliette. When they stop to ask for directions Nick sees a local man (Tim) woge into a Klaustreich, although he does not know the name of the Wesen, Later that night the pair of then witness Tim abusing his wife Robin and call the local police. The Sheriff arrives, enters and leaves quickly. Once Juliette is asleep Nick calls Monroe for information about the Wesen he saw and receives the low down on Klaustreich. The next day, while shopping with Juliette, Nick sees Robin woge into a Seltenvogel. He then goes outside to call Monroe for information. As Monroe was helping Rosalee in the spice shop at the time she overhears the conversation and they tell Nick about the possibility that Robin is about to produce an Unbezahlbar, and that Tim will probably kill her to retrieve it. Nick goes looking for Robin, and finds Gary's truck with his body inside. He then goes to Tim and Robin's house and rescues Robin. He takes Robin back to the cabin he and Juliette are renting where he calls the Sheriff. Robin then tells him that the Sheriff is Tim's cousin and accomplice. As the Sheriff arrives Robin panics and flees with Nick in pursuit. She does not get far, because of the pressure of the Unbezahlbar on her windpipe. Nick video calls Rosalee for instructions on how to safely remove the stone. Just as Nick completes the operation the cousins arrive and Nick manages to subdue the Sheriff while Tim runs away with the stone. Juliette keeps her gun on the Sheriff while Nick peruses Tim. Tim trips and the stone smashes just as Nick catches up. Nick is then able to arrest him. Back home Nick proposes to Juliette who turns him down because she feels he is hiding things from her.

Nick is in the trailer trying to find what the key unlocks when Juliette calls him to remind him about the dinner with Hank and his girlfriend. He spills some ink onto the key and notices that it prints a piece of a map.

When they arrive at the restaurant, Nick is surprised to find that Hank's date is Adalind. Out of sight of the others Nick warns Adalind to leave Hank alone. Adalind tells Nick that there is nothing he can do, and leaves. Hank joins Nick in the restroom and asks what is wrong. Nick says that it's between him and Juliette. Just then they are called to a double homicide.

At the scene Wu briefs Nick and Hank on the double murder and how it seems that the two victims shot each other. He then eats his chap stick, and when Nick questions him he does not respond.

Back at the station Nick tells Hank that he'll take the cell phone they found at the scene down to the lab, as Hank leaves to go home. Now that Nick is alone with Wu, he asks him if he is alright. He replies that he has had some stomach problems and is gaining weight. He then passes out. Nick calls for a medic and starts first aid on Wu.

At the hospital Nick receives an update on Wu's condition and shown the odd assortment of things that he has eaten. He decides to consult Monroe as to whether it could be related to his earlier collapse. They decide to consult Rosalee at the spice shop. The two Wesen continue their research when Nick leaves to return to the murder investigation.

The next day Hank is distracted by thoughts of Adalind so Nick discusses the case with Captain Renard, who tells him that the victims have political connections in Europe, and that they may have to let this one go. Before Nick can reply, he receives a call from Monroe telling him that if they are right, Hank is "knocking on Heaven's door."

Nick rushes over to the spice shop where they tell him that the potion is probably Le mort pour l'amour. They have made a cure and decide to test it out on Wu as it is also causing his illness. They go to Wu's home and administer the cure, which works. Nick then calls Hank, but because he's on Adalind's doorstep, he doesn't want to talk.

They rush to Adalind's house, but she has left and Hank is unconscious in her bed. Rosalee tells Nick that the cure won't work on Hank now, since he and Adalind have had sex. The only way to cure him is with the blood of the Hexenbiest who made the potion. Just then Nick gets a call from Adalind telling him to bring her the key. Rosalee tells Nick that he can't kill Adalind as that won't break the spell, but if she drinks some of his blood that will destroy the Hexenbiest spirit within her and cure Hank.

Nick and Adalind meet and fight. During the fight Nick kisses Adalind on the lips. She retaliates by biting his lip and inadvertently swallows some of his blood. The spirit leaves Adalind and Monroe calls to say that Hank is awake.

The episode ends with Nick looking at maps in the trailer to see where the key fragment is located.

Nick is first seen in this episode in Aunt Marie's trailer writing an entry in the Grimm Diaries about the Klaustriech he encountered at Whispering Pines. Later, he and Hank are called to a shooting incident at Portland Bus Station. Once there they interview Melvin the bus driver who provides a statement and identifies Ian Harmon as the victim. Later Nick and Hank are called to a bar where the bartender has been murdered. At the site Ian Harmon's passport is found and a witness calling himself Max Kurtz further implicates Ian. Nick notices that he is a Hundjäger when he inadvertently woges, and is recognized in return. Rosalee and Monroe who have been tending Ian's wound call Nick for assistance and when he arrives has to be convinced that Ian did not kill the bartender, by Rosalee and Monroe alibiing him. Ian brings Nick up to speed regarding Edgar Waltz, the Verrat and the Laufer. Nick decides to hunt Waltz and turn a blind eye to Rosalee and Monroe helping Ian with false papers. Nick goes to the trailer and watches the Film of the White Terror about the Verrat's actions during the Spanish Civil War. Waltz calls to arrange a Freidenreden, Nick agrees and then calls Monroe to find out what this entails. Nick meets Waltz the next day where he admits to the murder of Quin, but shows Nick his gun and says that he will kill innocent people if Nick tries anything. He then leaves. Nick and Hank consult with Renard and Nick relates his meeting with Waltz. They trace the calls to Waltz's phone and head to Reginald's camera shop to find Reginald's body and no Waltz. Monroe calls Nick to tell him that Waltz has kidnapped Rosalee and will kill her unless he hands Ian over. Monroe and Ian are heading for the spice shop and Nick tells them to wait until he arrives. When Nick arrive outside the spice shop Ian tries to convince him and Monroe to remain outside, but Nick enters and claims to have Ian. This surprises Waltz, who is even more surprised when Monroe enters also claiming to have Ian. Waltz thinks that Monroe is Fuchsbau and is momentarily stunned when he woges into his Blutbad form, allowing Ian to kill him. Nick then tells Monroe to get rid of Waltz's body while he takes Ian away. At the bus station, Nick gives Ian the passport and money prepared by Rosalee and drives away.

Nick decides that he should practice with the weapons contained in the Trailer's weapons cabinet, so enlists Monroe's help and the two of them happily massacre the contents of an entire fruit stall in the woods. Next day Nick is called to the site of Robert Grosszahn's murder and along with Hank is briefed by Sergeant Wu. When dispatch reports back with Arnold Rosarot's details from the 9-1-1 call, Nick and Hank head for his residence. Once there, they find that it is deserted, but Nick sees a photograph of Bud Wurstner, John Oblinger and a third man whom he presumes is Arnold. At home while working on the case Nick writes the word 'Eisbiber' and when Juliette asks about it he says that it is a possible witness. Juliette then persuades Nick to invite Monroe over for dinner. Next morning he visits Monroe and invites him for dinner. They both agree on a story, about their relationship, that is based on truth. Nick and Hank then visit Robert's office and discover that he was having trouble with building inspector Sal Butrell. They interview Sal, but he has an alibi. During the interview Nick realizes that Sal is a Hasslich. Nick goes to see Bud, to ask about Arnold. Bud agrees to contact Nick if he can find Arnold. Monroe comes over for dinner, and the conversation gets weird when there are deviations from agreed story, but Monroe changes the subject to ask for the vegan salmon recipe. Nick is helping Juliette clear up after the meal when he receives a call from Bud asking him to go to the old power plant for a lodge meeting. At the lodge meeting only Monique sides with Bud and John on a motion that Arnold should help Nick. Nick leaves the lodge disappointed, but tells Bud that he is brave, as he knew that Nick was a Grimm when he visited his house to give them a quilt. Arnold, however, decides that he will make a statement regarding Robert's murder, allowing Nick and Hank to arrest Sal. While taking Arnod back to the lodge Nick realises that they are being followed, so tells the Eisbibers to go into the lodge while he deals with the situation. Nick realises that the followers were two Reapers, so fights the two together. He manges to cause one to decapitate the other, and then kills the remaining one with his Doppelarmbrust. Nick then calls Monroe for assistance in disposing of the bodies, and at Monroe's suggestion sends the Reapers' heads back to their 'distributor'.

Nick is one of the cops at the scene of the murder of Mavis Kerfield, and is confused like everyone else as to what could have been behind the unusual circumstances regarding the death. When Hank voices how he's wondering why all the glass is shattered, Nick mentions the fact that most of the glass appeared to have come from the lamps and chandelier, so the killer may have broken it all to keep the place dark at the time of the kill, but then Hank counters that this theory doesn't explain why the killer shattered the mirror. Adding to the confusion, the two detectives also make note of how Mavis must have died at the exact same time as the glass was broken as there is no sign of Mavis getting her feet cut up by stepping on shards of broken glass.

After interviewing Mavis' daughters, Tiffany and Taylor, they learn about how Arthur Jarvis and Spencer Harrison had held a meeting with their mother on the day she died in which they asked her to give them money to help Arthur out through some financial troubles. With this new information in mind, the two detectives travel to the Jarvis household where they are greeted by Mavis' stepdaughter, Lucinda. When the two detectives come into the house and reveal the news of Mavis' death to Arthur, Spencer, and Lucinda, all appear surprised. In fact, Spencer is so surprised that Nick sees him morph into a bat-like creature.

Later at the precinct Nick and Hank interview Arthur, Lucinda, and Spencer. With this phase of the investigation out of the way, Nick returns home and he later ends up discussing with Juliette about how lately he's been having the case of his parent's deaths on his mind, and she offers to help him gain information on the case to help him get closure.

Later on Nick and Monroe meet up at the trailer where Nick asks Monroe for information on the bat-like creature he saw Spencer morph into, and Monroe is quick to identify Spencer as a Murciélago, and also tells Nick about a piece of equipment Grimms commonly use against these creatures called the Murciélago Matraca, which emits sonic noise waves that momentarily put the creature's own super sonic shrieks out of commission. Monroe then proceeds to demonstrate how the machine works, much to the expense of a potion bottle.

Armed with this new knowledge, Nick decides that he may have found the top suspect of his case in Spencer Harrison. He goes back to the Jarvis household to question Spencer, only to be told by Arthur that Spencer has already left to go visit the Kerfields. When Nick arrives, he finds Spencer already there at the scene of Lucinda's killing of Tiffany, and proceeds to arrest him, revealing to Spencer about his being a Grimm in the process.

At the precinct while Nick and Hank are briefing Captain Renard, Wu interrupts to say that Spencer wants to confess. In the interrogation room, Spencer says that he can emit a high pitched sound that can kill people. Hank leaves at this point saying that he is obviously playing the insanity card. Once Hank has left, Spencer tells Nick about Lucinda and her reaction when she doesn't get her own way. Nick then leaves to tell Hank the new information.

The police head to Taylor's house. Nick calls her to tell her to stay inside and lock her doors. When Nick and Hank arrive, they see Lucinda fleeing, so they pursue her. As she runs into a building, Monroe pulls up with the Murciélago Matraca, which they set up in front of the house. From the rear of the building they hear a scream and when they investigate they find the bodies of Spencer and Lucinda.

Nick and Hank bring the Murciélago Matraca to Captain Renard's office and tell him that's what was killing people. Renard ask if either of them wan to show him how it works, but Nick and Hank just look at each other in no rush to turn it on.

Nick is called to the scene of a double murder by Juliette who has discovered two bodies whilst treating an injured horse. A witness at the scene claims that the were attacked by "Big Foot". A video camera found at the scene reveals that the attacker was wearing a clothes, specifically a red plaid shirt. Early the next morning Nick receives a call from Monroe asking him to come over. When Nick arrives Monroe shows him his friend Larry Mackenzie a Wildermann who is stuck in woge. Nick recognizes Larry's shirt as the one on the video, and as the police dog team are getting close Monroe leaves Larry with Nick while he lays a false trail using the shirt. When Monroe returns Larry recovers consciousness and pulls something out of his neck, and dies. When he dies he retracts to human form. Nick and Monroe leave the body in the woods where it will be found with the thing from his neck in his hand. When the police find the body the thing is identified as a subcutaneous drug pump. Monroe tells Nick that Larry had a therapist called Konstantin Brinkerhoff, but the initial interview with him reveals no new information. When the pump has been traced, the police discover that four were ordered by Dr Brinkerhoff, and only three have been found so far. Nick and Hank then head off to re-interview Dr. Brinkerhoff. When they get to his office they discover that he has run into a theater having taken a woman hostage. When Nick finds the hostage on the lighting gantry he is attacked by an enraged and woged Dr Brinkerhoff. The fight ends with Dr. Brinkerhoff falling off the gantry whilst woged. Hank sees him retract, but Nick claims to have seen nothing unusual.

When Nick and Hank are looking at a picture of Akira Kimura and discussing his tattoo, Nick tells Hank that Kimura was involved in the death of his parents.

When Nick gets home and realizes that Juliette has been scratched by Adalind's cat he tries to make her go to hospital. Juliette understandably does not see the point, and thinks he is over-reacting. Nick then takes her to the Trailer and tries to explain about him being a Grimm and that Adalind is a witch. Juliette runs out of the trailer, and tells Nick that he needs psychiatric help. Nick convinces her to go with him to Monroe's Home where he hopes she can be convinced by the sight of Monroe wogeing. Before this happens she collapses into a coma, so Nick and Monroe rush her to Treeview Hospital. They then go to Juliette's clinic and take the cat to the Spice Shop, so Rosalee can try and determine what Adalind has done to Juliette.

When Nick returns home he finds Kimura waiting for him, he shoots at him with his Doppelarmbrust, but misses and so the two fight. Nick knocks Kimura down, but before he can interrogate him is attacked by a mysterious woman dressed entirely in black. The woman dodges Nick's attacks and injects Kimura. When Nick points his gun at her she calls him "Nicky" and the episode ends with her telling him that she is his mother.

Nick is first seen in this episode fighting Akira Kimura in the same confrontation from. After Kimura's defeat by Nick and the mysterious woman in black, Nick learns that it is his mother. Later that morning, he confronts his mother about why she was never there for him while he was being raised by his aunt and why she let him think that she was dead. After his mother explains, he later ends up having to break up a fight between her, Monroe, and Rosalee when the latter two show up at his house and Monroe is nearly stabbed to death by his mother. After this, Nick and Hank are called to the scene of the gruesome murders of the people at the shipyard. The FBI arrive and take charge, so Nick and his Mom go to the trailer to work out what sort of Wesen they are dealing with. Once they determine that they are dealing with a Mauvais Dentes, they go to question Kimura, but he has been killed in jail. Nick then gets a call from Special Agent Kanigher asking him to go to the warehouse. He and Kelly head over there. When Nick arrives he goes to investigate and apparently finds two bodies. His phone then rings, it is Monroe and Rosalee saying they've made the cure, but it is unstable so he needs to get to the hospital quickly. During the call one of the bodies rises and is revealed to be Marnassier who woges as he approaches Nick from behind.

Nick and Marnassier fight and Nick fires a shot a Marnassier which misses. Marnassier is killed by Kelly and Nick rushes to the hospital forgetting to retrieve his gun, and the bullet he fired. He rushes to the hospital, meets up with Monroe and Rosalee, forces his way into Juliette's room and puts the drops in her eyes.

Hank and Nick are called to the scene of the death of Marnassier. The two FBI agents taking over the scene dismiss them, but Nick is able to retrieve his gun which he later throws into the lake. Later, at the precinct, Nick is approached by the FBI agents regarding his whereabouts earlier, as he is now a suspect. When they ask about his gun he says that he was not wearing one that day, as he was going to the hospital.

When Nick arrives home he discusses the situation with his mother and they decide that she will visit Catherine Schade for information. Nick leaves the house to distract the surveillance.just before his mother leaves.

The FBI ask Nick for a DNA sample, which he provides and when the result is a near match, he suggests to the FBI that his mother must have been there. Nick says to the FBI that Special Agent Kanigher and Special Agent Durwell killed the John Doe before succumbing to their wounds, and asks why won't they accept that.

Nick and Kelly decide that she should leave Portland with the Coins of Zakynthos, so he drives her to the station.

Nick is called to the hospital as Juliette has woken up. He kisses her, but she does not recognize him.

When Nick visits Juliette in hospital, she recognizes him as the cop who brought her in, but not as her boyfriend. She does, however, remember Monroe and the dinner, but not that Nick was also in attendance.

Hank's friend Jarold Kampfer arrives at the Precinct to report that his seventeen year-old daughter Carly, is missing. While he is giving the information he inadvertently woges and shows his Coyotl side to Nick. Nick then goes to research Coyotls and learns about the Aseveración ritual. When he returns Jarold thinks that this is possible and says that his brother-in-law Hayden Walker may be involved. The detective soon trace Hayden to a farm, where they manage to find Carly and then take refuge in a barn. Carly is panicking and woges her eyes in front of Nick. She then runs to Hank for protection saying the Nick is going to kill her, in the process fully woging. When Hank saw Carly woge, he wanted to kill her, but Nick explained what was happening. Nick then came up with a plan to capture Hayden and the rest of the pack. When Nick apologized for keeping Hank in the dark about the Wesen world, Hank replied that this was one of the best days of his life, as he may be crazy, but at least he's not alone.

Juliette is released from hospital and Nick takes her home. When they arrive Juliette goes upstairs to the bedroom  while Nick looks ruefully at the sofa.

Nick begins to share what he knows about the Wesen World, along with his role and heritage of policing them as a Grimm, with Hank. He states that if Hank did not have him as a partner, he probably would not have known that beings like them exist. They then both get paged to report to a car accident. Once there, they follow a blood trail to find Carl Stanton trashing an office. The two detectives tell him to drop his weapon, and Nick tells Hank that he saw him Woge. Carl then charges at them and they are forced to shoot him.

Nick then goes to Monroe's home to let him know that he's told Hank about the Wesen world.

Later, Hank and Nick go to the morgue. Dr. Harper tells them that Carl appears to have been infected with something similar to the Ebola virus. Hank is worried about it being contagious, but Harper reassures him by saying that they look healthy enough after one full day since coming in contact with the virus.

Nick goes to the trailer and researches Wesen diseases, learning about Fluvus Pestilentia.

They then go to Carl Stanton's house. There, Wu had had to kill Phyllis Stanton when she attacked him. The two detectives investigate the body and find that she too is infected with some sort of virus. They also find a briefcase that had documents showing a couple of pigs who had fallen to a similar virus.

Nick calls Monroe to ask about the yellow plague and whether there is a cure as there may be about to be an outbreak.

They then get a call about the Park Ranger. When they go check it out he runs towards them, then collapses. They then put him in the car and take him to the spice shop. At the spice shop, Nick tells Hank that Monroe and Rosalee are Wesen, and discovering that Rosalee has run away, Nick chases after her. He finds her in the alley way, however she has succumbed to the anger stage of the disease, and holding a pair of scissors tries to attack Nick.

As the much stronger being however, Nick disarms her and knocks her out cold in two moves. He carries her back to the others so she can receive the antidote. He later checks up on Ryan's progress in recovery.

Nick meets Bud in a bar where Bud tells Nick that he told Juliette that Nick was a Grimm, and when she didn't understand he said it meant that he was a good person. They agree that if Juliette wants a further meeting he should be unavailable. During the conversation Nick sense something, but when he looks round there is nothing strange happening. Nick and Hank are asked by Captain Renard to investigate some funds apparently stolen by a church accountant. After they talk to Lance Calvin (the reverend of a church that was stolen from), they go to the accountant's workplace. At the mulching company, they find the accountants body...in the wood chipper.

The detectives then go back to the church to tell Lance the bad news and that the case is now officially a homicide. Nick realizes that the congregation are Seelenguter, and that Lance is a Blutbad. Because Lance realizes the Nick is a Grimm he suggests they continue the discussion in his office. There, he tries to convince them that he is a Wieder Blutbad, saying that if Nick can turn away from his violent heritage then so can a Blutbad.

Nick and Hank go to Monroe's house to ask Monroe if he would go undercover. After calling a Blutbad pastor and a Seelengut congregation a "recipe for lunch," he agrees.

After investigating further, they find out that Lance's first church was hit with embezzling. Also, Megan Marston was a member of both churches and her husband was the first accountant. They call her in for questioning, and when she gets frightened with Nick being a Grimm, Hank reassures her by saying that "he is not that kind of...Grimm." Megan is shocked that they would think that she would or could kill one of her own when they ask if she had anything to do with the murders.

Nick goes to the trailer to research Seelenguter, and when leaving is attacked by the Nuckelavee, David Esquibel. After an extended fight Nick kills him with a maul.

Hank and Nick go back to the church when they find evidence that Lance and Megan had traveled to the Caribbean several times. They arrive just in time to save Monroe from an angry group of Seelenguter.

Nick and Juliette are having a getting to know you dinner at her suggestion when he receives a call from Monroe requesting his presence, as someone is trying to kill him. When Nick arrives at Monroe's Home he is surprised to see Angelina there, and tries to arrest her. Monroe talks him out of this action as she risked her life to warn him.

Nick takes Monroe to Hank's home for safety, and then goes with Angelina to investigate the murder of Buxton Jacobs. Since Angelina was the murderer, she is able to convince the on scene Detective that he was killed in self-defense by a woman he was attempting to rape.

By listening into Angelina's conversation with the contact for the killing, Nick realizes that along with his friends he is being dragged into a Royal power struggle.

Nick convinces Hank that they should work with Angelina to save Monroe, rather than arrest her.

When the exchange goes wrong Nick and Arbok fight and Arbok temporarily has the advantage, until Hank kills him.

While Monroe is mourning Angelina in the Blutbad way, Nick calls Rosalee to let her know that Monroe is okay. When he gets home he finds a note from Juliette saying "Thanks for the new memories".

Nick dreams that Juliette remembers him, and things between them are back to normal and is upset when he awakens and realizes he was dreaming. Nick and Hank are called to investigate the murder of Leo Stiles at a gas station and after looking at the cameras they suspect William Granger is behind the murder. They notice that Granger has his daughter, April with him so they put out an Amber Alert in hopes of stopping William Granger from harming anyone else.

Hank and Nick go to Granger's house to investigate, where they discover his ex-wife, Lilly beaten in the bathroom. Nick notices her briefly woge into something before she passes out. Hank calls for medics and they start searching the house where they discover Granger had recently ordered a lot of building supplies.

Nick takes Hank to the trailer for the first time to figure out what kind of Wesen Lilly Granger was. They discover that she is a Drang-Zorn, so they assume that William Granger is one also. Nick shows Hank the weapons cabinet in the trailer, where Hank recognizes the Siegbarste Gewehr that was used to kill Oleg Stark and save his life. Nick tells Hank that Monroe was the one to shoot Stark.

Nick,along with Hank, the SERT officers and police dogs go searching for Granger to rescue April. They discover the underground area that William built, and find April. They bring her back to the police station, where a child services woman picks her up to bring her to a foster home for a few days until her mom is out of the hospital.

Hank and Nick go to Treeview Hospital, where they assume William Granger is going since Lilly is there. They find him in Lilly's room and handcuff him, but they discover that William is innocent and April is the one who beat Lilly and murdered that man at the gas station. They head to the foster home that April is at and arrive right after she attacked the Foster dad. They go to the backyard where they find April swinging and they bring her back to the station.

Nick locks April in a separate room and then Jess comes in to take her, she says that Monroe thinks highly of him, and when asked if she can control April briefly woges into a Löwen and says yes.

Nick and Juliette are dancing after a candlelight dinner and then begin to kiss before Juliette breaks away leaving Nick confused.

Nick and Juliette are preparing to go to a department function and he warns he that Captain Renard will be giving a speech. While at he function Nick and Hank are called away to investigate the murder of Brandon Kingston, who was found with his throat ripped out. They find out he was in a school competition and go to question the other competitors. They find out that Brandon was well liked by all the students and didn't have any enemies. Coach Don Anker arrives and confronts the detectives, saying that if he finds Brandon's murderer he will personally kill whoever is responsible. While making these threats he briefly woges into a Löwen, a change not missed by Nick who immediately promotes Coach Anker to the head of the suspect list.

When they find Pierce Higgins's watch clutched in the hand of the murdered Jenny Lee, one of the students from Brandon's team. They confront Pierce at his house.While talking to the Higgins'  Nick notices that they both woge into an unfamiliar Wesen, so they go to the trailer and determine that Pierce and his mother are Genio Innocuo.

Deciding that they need to question Coach Anker further, they visit his home, only to find him dead like the others.

Pierce calls saying that he suspects his mother as the killer and the two detectives rush to his house. There they find Pierce in Löwen form attacking his mother. Nick prevents him killing her, but he escapes and runs up to the top of a building and prepares to jump. Nick and Hank try to talk him out of it but he jumps anyway. Nick was close enough to catch him however and they pull him back to safety. They later tell Renard in the debriefing that his mother had experimented on Pierce before he was even born, and try to put it off as a gene-induced mental illness that had caused him to want to murder his friends.

Nick is in the trailer and picks up his flail. He takes the flail to Monroe's house where Monroe incorporates it into one of his Halloween decorations. While there he is called to the scene of a child abduction. Once there, he and Hank find some bikers who had shot a video with the abductor walking by in the background. She is shown walking away with the child (Rafael) calmly holding her hand.

Back at the precinct, Hank and Nick are informing Renard on the situation when Ryan interrupts saying that the Spanish translator is here. Juliette (the translator) then enters the office and translates for Luis.

The two detectives go with Juliette back to Luis's house. Once there, they are shown around to see if they could find any clues as to who the abductor was.

When they return to the precinct, they are introduced to Valentina Espinosa, who had said she had some knowledge with The Woman. Hank thinks that Rafael may be dead already, but Valentina says all evidence points to the children being drowned together at midnight. During this discussion Nick notices that Valentina's eyes woge yellow. Hank and Nick then get a call that a second child had just been abducted. Valentina shows them on a map of Portland, two rivers converging into one. She then says that one child will be abducted from each river, assuming it is the same Woman that she has tracked before.

They go to the crime scene and Renard informs Hank and Nick that Valentina is not a detective anymore, and that she had been discharged a year ago. Nick tries to get her back in the car, but she woges and realizes that Nick is a Grimm and thinks that he will kill her. He says he will not, but that Hank will shoot her in the head if she causes trouble.

Hank and Nick go to the trailer and research on The Woman, who turns out to be called La Llorona. They see a symbol that is the same as the river shape Valentina showed them. They then decide that she might be telling the truth and rush to break her out of jail so that she can assist with the investigation.

With the help of Valentina, they find out where The Woman is going to drown the kids. They arrive just in time to stop her and Hank holds the kids while Nick goes after The Woman. Nick manages to successfully grab the woman when she is in he demonic, corporeal from and they wrestle under the water. When the woman takes on her incorporeal human form she is able to escape. Nick and Hank return the children to their parents..

Nick is on the couch dreaming about a missing child case when Juliette wakes him from his nightmare.Hank and Nick go to Adrian Zayne's house to question him about the kidnapping of Donna Reynolds. Adrian is burning something when the arrive, As Hank heads for the fire Zayne panics and woges into a Schakal. When he realises that Nick is a Grimm he panics even more and flee, Nick easily catches and overpowers him.

Because Nick has to free Zayne due to lack of evidence he asks Monroe to make him some Serum Exomologesis which he loads into his Doppelarmbrust. He then goes to Zayne's house but finds him tortured and dead. Hank arrives and initially thinks Nick is responsible, but Nick has Monroe as an alibi. When they hear sirens, Hank goes to see what is occurring while Nick hides the Doppelarmbrust.

After greeting the other officers, Wu tells them that they came after receiving Zayne's confession and that he is impressed in the two detectives interrogation skills. After studying the record of his 911 call-confession, they determine that he had been tortured for the information and suspect the family members.

Nick receives a call from Monroe regarding the symbol that was branded onto Zayne's body asking him to come over. As Nick ends the call with Monroe, a panicking Bud calls and Nick has to reassure him that he is working on the case. Monroe explains to Nick about the Endezeichen Grimms and how he has stop this before the Wesen community blame him. Nick then receives a call from the other Grimm berating him for not killing all Wesen.

After finding the video of Zayne's torture online, Hank and Nick go question the Reynolds. The parents cannot help, but Donna is able to tell them where she was kidnapped. Using this information they track down a van belonging to Richard Berna, who when confronted woges into a Schakal, and as he realizes Nick is a Grimm starts screaming that Nick killed Zayne. Nick just shrugs.

After finding enough evidence in the van to arrest him, Hank and Nick go back to Richard's holding cell, only to find that he had disappeared. They then go to his house and find him dead, suspecting someone on the task force as they were the only ones to know that Richard had been brought in. Nick then receives a second call from the other Grimm berating him for not killing Berna as soon as he knew he was Wesen.

Back at the Precinct, Ryan brings a panicking Bud to Nick who once again reassures him that he is working on the situation. Bud then leaves.

After discovering that Ryan released Berna they go in search of him and discover that he had followed Bud and so find him about to torture him in his repair shop. Nick strikes Ryan who woges into a Lebensauger and begs Nick to kill him. Nick arrests him and the two detectives release Bud who after hugging them in thanks goes home.

With his new knowledge of the Wesen world, Hank is concerned that an old death penalty case could have had a Wesen element. He convinces Nick to help him check the case. The detectives check with the other cops on the case, the killers lawyer, his girlfriend and finally Craig Ferren, the killer himself.

With some drawings by Craig as a starting point for research in the trailer, they soon discover that the supposed victim Miles Kreski and his surviving brother John Kreski could be Wendigo. At his workplace they provoke him into woging and Nick confirms that he is a Wendigo.

They decide to go to John's current house and enter, on the grounds that he had a warrant for skipping jury duty. They find a secret trapdoor underneath the fridge, and climb down to the underside of the house. From there they find a second lift panel, which covered up the remains of several humans.

With substantial evidence, they decide to call the governor for a stay of execution for Craig. John Kreski arrives back at his house however and attacks them, blocking the opening to the tunnel with the fallen fridge and trapping Nick inside.

After he escapes, Nick calls Lauren Castro, the D.A. and obtains a stay of execution for Craig.

Nick receives a call from Juliette saying they need to talk. As he puts the phone down he receives a call from Monroe asking him to drop by before he goes home. At the spice shop Monroe tells Nick that he saw Juliette with another man, and that their relationship could be caused by a spell. He says that he does not know the man, and that Juliette definitely knows that he knows. Nick leaves and confronts Juliette who tells him that there is someone else, but that nothing has occurred.

Nick goes to visit Hank in hospital and learns of Adalind's possible involvement in the attack upon him. He suspects that Adalind would contact Juliette and so traces her cellphone. The police arrest Adalind and Juliette is angry with Nick for using her to trap Adalind.

Monroe calls Nick and confirms that Hank was attacked by Hundjäger. During interrogation Nick learns Adalind's hotel room number. Monroe goes to the hotel room and leads the Hundjäger into an empty lot where he and Nick fight and kill them.

Nick decides that he is not sleeping on the sofa anymore, so moves in with Monroe. When he tells Monroe that he has moved out Monroe shows him a tape of Captain Renard at a press conference and tells him that he was the man he saw with Juliette.

This episode starts immediately after the previous one, with Monroe have shown Nick that it is Captain Renard who is involved with Juliette. Monroe is desperately trying to calm Nick down and prevent him from doing something calamitous when Nick is called to investigate a quadruple homicide. The bodies of the four Hundjäger killed by Nick and Monroe earlier that evening have been found. At the scene Nick makes some very astute observations, but does not reveal his own involvement. When Captain Renard arrives the conversations between them are strained.

Next morning Sergeant Wu bring the tape of Monroe leaving the hotel pursued by the Hundjäger, but Nick convinces everyone that Monroe has no involvement. Later that day Nick is called to Juliette's home where there have been reports of gunfire. Nick tells Juliette that he knows who the other person she's seeing is, but she doesn't say anything. Nick and Wu agree that the incident is to be classed as attempted home invasion with no injuries.

Hank tells Nick that the Captain has been snooping around his desk and when Nick checks, he realizes that the key is missing. He then receives a call from him arranging a meeting. The meeting place is the Postman's house, and when Captain Renard arrives Nick punches him, and the two fight. During the fight Captain Renard woges into his Zauberbiest form. When the Captain gives the key back, this calms Nick sufficiently for them to talk. The Captain says that he would end the thing with Juliette if he knew how. Nick tells him that he knows how and the two together turn up on Juliette's doorstep, and with her proceed to the Spice Shop where Rosalee mixes up the Infatuation Cure for Nick who drinks it, collapses on the floor and turns red.

At the start of the episode Nick is still red and unconscious on the floor of the spice shop after having drunk the potion at the end of the previous episode. Juliette want to call for an ambulance, but Monroe persuades her to wait. After a short while Nick recovers consciousness, and Rosalee leads Juliette and Captain Renard into another room while Monroe takes a small amount of blood from Nick's finger. Nick follows Juliette home to ensure she arrives safely.

Nick and Hank are called to a bank robbery, where Monroe was one of the witnesses, Monroe tells the detectives that the robbers were Wesen who committed the robbery whilst fully woged. This is a problem because they have broken the most important Wesen law: the Gesetzbuch Ehrenkodex.

Nick and Captain Renard agree that they can work together to thwart the plans of the Captain's family.

Nick receives a call from Monroe who is outside a bar frequented by criminal Wesen. Nick tells him to wait for him and Hank to arrive. When they arrive Monroe enters the bar and shortly a fight breaks out, so Nick and Hank enter the bar and collect the names of the participants including the bank robbers who Monroe recognized.

Next morning Nick and Hank head to the address for the robbers and discover that it is an abandoned factory whose only inhabitant is a homeless man who is afraid of "monsters". The homeless man tells them that one of them is named Gus.

Reviewing Cole's record they find that he shared a cell with Gus Campbell, so head to his address where they find his body. On his boot soles Hank notices paint similar to that in the factory, so they head there. As they approach the factory Cole and Krystal shoot at them, and they return fire. Nick arrests Cole while Hank arrests Krystal. While they are taking them into the Precinct for booking Cole and Krystal are shot dead by an unknown assassin who is promptly arrested.

Nick is having a meal with Hank, Monroe and Rosalee and they are discussing Nick's information about Captain Renard being a Royal and a Zauberbiest who woke Juliette from her coma. Next day when Nick, Hank and Sgt Wu are investigating the death of Molly Fisk, he notices the extreme redness of her eyes. At the grief support group where Molly met Andre the detectives find a witness who is able to help the police artist produce a sketch of Andre. The detectives are then called to Casey and Kelly's house where Andre has just attacked Kelly. Casey is able to confirm the sketch and provide a description of Andre's car. The car is spotted near a high school where another grief support group is meeting. When the detectives arrive they spot Andre and pursue him. While searching for Andre they become separated and Nick is spayed by Andre, initially he sees through a red mist and then goes blind. As they know that they are dealing with a Jinnamuru Xunte, Nick insists on going to the spice shop as he knows that the hospital can't help. At the spice shop it becomes apparent that Nick's other senses have been enhanced, as he is able to hear whispered conversations. The car Andre carjacked to escape from the high school is spotted near Casey's home, and so they all head there. At the house they interrupt Andre attacking Casey and Nick chases him upstairs where he is able to find and defeat Andre using his newly enhanced hearing. Monroe scoops out Andre's eye and Rosalee then completes the cure and restores Nick's sight. Nick is later seen massacring more fruit whilst blindfolded.

Nick and Hank are called to the offices of a software company where Brody Crawford has been sliced in half at the waist. The detectives interview the other staff members and discover that they were celebrating a new game release. Painted on the interior wall of the building are the cryptic words "play my game", which means nothing to the other staff.

While at Monroe's house Nick asks Monroe if he knows any Wesen who use acid, but Monroe tells him he's never heard of any. He then receives a call from the manager of the company, Dominick Spinner, telling him that the victim's girlfriend's previous boyfriend is named Ridley Cooper. The next day the detectives interview him and his sister, but they were playing the game at the time of the murder. They determine that Brody's avatar was killed three hours before the murder.

Nick and Hank go to the trailer and determine that they could be dealing with a Fuchsteufelwild, and if so, his name will likely be an anagram of "Rumpelstiltskin". As Jenna Marshall remembered the name began with a "T" they go through the game user list compared to the list of anagrams and find the matching name "Trinket Lipslums".

The police set a trap for Lipslums and when he is lured into it, Nick and Hank surprise him and chase him to the roof where Nick calls him by name, and when he woges, Nick tells him that won't work either. Lipslums realizes that he's up against a Grimm, but is unable to accept defeat. Shouting that he can't lose, Lipslums throws himself off the building.

Monroe tells Nick that he mentioned the trailer to Juliette and she wants to visit it. Nick agrees to let Monroe take her.

Nick receives a call from Monroe telling him that there is jury tampering occurring at the court house. When Nick and Hank arrive Monroe tells them that the defense lawyer Barry Kellogg is a Ziegevolk and using his pheromones to influence the jury. Back at the spice shop Rosalee finds a Geruck Gland Neutralizing Potion which if used would stop the pheromones. In order to collect some of Kellogg's sweat for the potion a woged Monroe chased Kellogg. Next day Hank and Nick interview Kellogg in his hotel room while Monroe injects the potion into one of his toads.

While everyone is celebrating the successful conclusion to the case in the back room of the spice shop, Kellogg enters the shop looking for help as his powers are failing and he doesn't know why. When Rosalee appears he recognizes and attacks her. Monroe woges and defends her, at which point Kellogg also recognizes him. Nick arrests Kellogg for attacking Rosalee telling him that nobody will believe his story.

Nick along with the rest of the precinct staff despatch Hank on his first holiday for four years.

Nick visits Juliette in the hospital after her car crash and she tells him that she can't see him any more and asks him to leave. Nick returns to Monroe's home where Monroe and Bud attempt to cheer him up by watching sports and drinking beer. During the game Nick receives a call about Jill Prembrey's body being found, so leaves to investigate. At the scene Sergeant Wu briefs Nick about the situation. They review the video footage Jill took on Mount Hood then go to the offices of EON industries where they interview her boss Thom Evans. Thom is able to identify the site of the video footage, so all three head there to look around. At the site Thom picks up some rocks, and they return to find their truck has been vandalised. Nick soon finds the vandal, Markus Hemmings a Taureus-Armenta, who flees when he realises that Nick is a Grimm. With Wu's help Nick arrests Markus. At the precinct Nick discusses the case with Captain Renard and they realise that the autopsy report on Markus's wife, who died 15 years ago, details injuries similar to those found on Jill's body. They both interview Markus, who tells them that he wasn't attacking Jill or them. but trying to warn them about taking what isn't theirs. He also says that he has seen what happens when Volcanalis rises. Outside the interview room Nick and Renard discuss the possibility that there is another being involved and that they may have to do this "off the books". Wu then informs them that there have been some similar attacks around volcanos on people taking rocks. Nick, remembers that Thom took some rocks, and Renard thinks that they should warn him. Nick and Renard arrive at Thom's house to find Volcanalis attacking him, and they order him to stop. Nick shoots Volcanalis several times with no apparent effect, and then pursues him until he disappears down a grating.

At the trailer Nick researches Taureus-Armenta and Volcanalis. The Volcanalis entry is in Latin, so they take it to Renard for translation, The entry states that a creature similar to Volcanalis destroyed Pompeii. They decide to re-interview Markus as he probably knows more about Volcanalis than any other person. Markus tells them that he knows no way of stopping Volcanalis and that he could stay on the mountain until "hell freezes over" and still not stop him. This gives Nick an idea and so Nick, Renard, Monroe and Markus go to the mountain to collect more rocks, which they take to an empty warehouse where Markus tells them to put the rocks in the middle as that is what Volcanalis will go for first, and them afterwards. As he is speaking a small tremour occurs and leaving Markus in the center, the others retreat to the outer edges of the room. As Volcanalis arrives, Markus shouts for them to "do it now", and the others hose Volcanalis down with liquid nitrogen from tanks they prepared earlier. Once Volcanalis has solidified Nick hands Markus a sledge hammer for him to smash Volcanalis and avenge his wife.

Nick is in the trailer trying to work where the map on the key could relate to, when he decides to consult Monroe. He interrupts Monroe and Rosalee kissing and retires to his room embarrassed. Monroe follows him and the two determine that it could relate to an area of Germany.

Next day he is talking with Captain Renard about the key when Wu interrupts to tell them that county have asked for assistance regarding some cattle mutilations, a possible homicide and that thewitness thinks that Aliens may be involved. When Wu and Nick arrive at Robert Hadley's farm they question him regarding the incident and Nick finds a piece of glowing skin. When they are leaving a UFOlogist called George Lazure questions them.

At the M.E.'s office Harper tells Nick that the skin is human, but contains luciferase, causing it to glow like fireflies. Wu then calls to tell Nick that there has been another Alien incident, this time an abduction. Nick asks Wu to investigate if there have been any other mutilations and what if any was their purpose.

Nick then decides to look in the trailer books to see if there could be a Wesen angle to the case and finds a picture of a Glühenvolk, but not much information. Wu calls to let him know that there had been 27 attacks starting in Nebraska, and that the ovaries had been removed from the dead cows. He decides to consult Rosalee at the Spice Shop.

At the spice shop Rosalee tells Nick that she thought Glühenvolk were extinct. When she hears about the mutilations and the number she produces a book and says that there must be two of them and that the female must be pregnant as cow ovaries are consumed to ensure foetal health. Monroe then arrives and all three deduce where the Glühenvolk are probably to be found. Nick is unsure about giving them assistance as one of them may be a murderer, but is convinced by Rosalee's argument that the baby is innocent.

Finding Lazure's trailer and realising that he is hunting the Glühenvolk for their skins gives added impetus to their hunt and they soon find the cabin where Jocelyn is resting. After introductions are made, Jocelyn starts to go into labor, and so Nick returns to his truck to get a first aid kit and some blankets. Just before the baby is born Vincent returns. While Vincent and Jocelyn are rejoicing, George Lazure bursts in and threatens the group with a gun loaded with Sauver Sa Peau bullets. Nick's revelation that he is a Grimm distracts Lazure enough for Monroe to attack him. During the fight Nick retrieves the gun and when Lazure returns fully woged Nick shoots him,

Nick then arranges for the body to be found in Maureen Rodriguez's truck whilst the Glühenvolk continue on their journey to Alaska in Lazure's truck.

Nick meets Hank on the return from his vacation at a diner and discovers that he has torn his Achilles tendon while zip lining with his ex-wife, Nadine. During their meeting shots are heard from across the street and while Hank calls it in, Nick rushes to investigate. As he enters the library he hears shots and discovers Anton Cole holding Khloe Sedgwick hostage. He identifies himself and Anton shoots in his direction. Nick manages to force Anton to flee without Khloe and gives chase. Anton escapes by diving into the canal. Nick and Hank then interview Khloe and learn that Anton was her ex-boyfriend and that he had just killed her current boyfriend the novelist Evan Childs. Khloe thanks Nick for saving her, then kisses his hand. Wu then tells them that they have found Anton's loft, so they go there to investigate. In the loft they discover lots of paintings of Khloe, and one showing the murder scene, which proves premeditation. Nick receives a call from Juliette inviting him to dinner that evening, and he accepts.

Nick then visits Khloe at her home for a follow up interview, during which she kisses him on lips, then woges into her Musai form. When she realizes that Nick is a Grimm, she becomes scared and backs away. Nick then receives a call from Monroe asking about his dinner date with Juliette. Nick leaves Khloe's house and goes to see Juliette.

At Juliette's house, Nick is brusque with her as he asks what she wants to talk about. While Juliette is explaining that she is slowly regaining her memory Nick is distracted by thoughts and hallucinations of Khloe. He leaves without eating.

Nick returns to Monroe's house, where in answer to a polite inquiry as to how the evening went, is rude to Monroe and Nick leaves.

Nick goes to a bar where Hank arrives to talk to him. While waiting for Hank, Nick draws a picture of Khloe woged which he shows Hank. When another patron repeatedly asks to show the drawing to his girlfriend, Nick punches him in the stomach and leaves the bar.

The next morning at the precinct, Nick tells Hank that the previous night is a blur. Nick is distracted and uninterested in anything until Wu reveals that they know what Anton was doing the previous night. Nick, Hank, Wu, and Captain Renard all head out and look at the mural of Khloe painted by Anton in a vacant lot. Nick then leaves with Wu following.

Nick arrives at Khloe's house where Khloe tells him that Anton is there and she wants him to prove his love for her by killing Anton. The two fight, but Nick easily overpowers Anton. The officer stationed outside Khloe's house and Captain Renard enter in time to prevent Nick from beating Anton to death, although Nick still hits Anton whilst he is handcuffed.

Back at the precinct, Nick is told by an officer that Anton has been processed and is in the cells. Nick then heads straight for the cells where he draws his gun and is about to shoot Anton when Captain Renard, Juliette, and Monroe arrive. Renard points his gun at Nick, saying that he can't save Nick if he shoots Anton. Juliette goes to Nick and tells him that she is there for him, just like he was for her. Nick then throws off the effects of Khloe's kiss and hugs Juliette.

Nick and Juliette arrive outside their home in Nick's car. She apologizes for her recent behavior and says that she wants them to try to become a couple once more, but to take it slowly. She invites him for dinner again, an invitation he accepts.

The next day Nick and Hank are called to Richard Mulpus's home after his altercation with Wu and Franco. Nick comments that although the home is trashed, the body of Lilly O'Hara is undamaged. When leaving the scene, Nick notices a man in a top hat among the onlookers.

At the precinct Hank finds a death certificate for Mulpus, so the detectives head over to the morgue to consult with Harper, who tells them that Mulpus is definitely dead now. She also tells them that all the usual drug tests have returned a negative result.

At the hospital where Mulpus' death certificate was issued, Nick and Hank consult with Dr. Feldman who assures them that according to his tests, Mulpus was dead. He says that the body is probably still in the hospital morgue. The detectives visit the morgue and speak with the Morgue Clerk who shows them where the body should be. There is no body, and no paperwork much to the clerk's consternation. As they leave Nick sees the man in the top hat again. They then go to see Lily O'Hara and find her missing, so they review the surveillance video, where Nick once again sees the man in the top hat, this time taking Lilly O'Hara out of the hospital in a wheelchair.

Nick and Hank go to the trailer to research the zombie state, and find information about what could be causing the problem. They determine that it is the work of a Cracher-Mortel. While at the trailer, Nick receives a call from Monroe asking him to drop by the spice shop on the way home as he has something to tell him. Nick and Hank return to the precinct to discuss the case with Captain Renard.

At the spice shop Monroe and Rosalee tell Nick how they woged for Juliette, and that she'll either accept them or she won't.

At Juliette's house, Nick knocks on the door and gives Juliette some flowers. They briefly talk about what she saw at the spice shop, then Juliette goes to put the flowers in water and Nick enters the house.

Nick and Juliette are finally having their dinner at the house. Juliette tells Nick that he does not need to knock as it is his home too. They then talk about recent events and start making out.

The next morning, while they are chatting, Nick is called into the precinct by Captain Renard.

Renard tells Nick that his brother, Eric, is in town for an unknown reason. When Eric calls, Sean puts the phone on speaker so that Nick can hear the conversation. Just as Eric terminates the call, Wu enters and tells them about the disturbances all over Portland.

When they arrive at scene, they are told that the perpetrators are upstairs, so they go through the coffee shop and upstairs where Lilly O'Hara attacks Wu, charges Nick, and leaps out of the window. Al the Tow Truck Driver then attacks Nick, but Nick eventually manages to knock him out. Just as he is about to handcuff him, he hears something and draws his gun, but it's Hank arriving to offer assistance. Nick decides that the best place for Al is the spice shop, so gives Hank his keys to bring his car to the rear entrance while he carries Al downstairs.

Hank and Nick decide to leave Al with Rosalee and Monroe where after explaining that they think a Cracher-Mortel is involved, Rosalee is able to find a cure that works in the violent phase. Nick and Hank leave Rosalee and Monroe to their concocting with the handcuff keys for Al.

Back at the precinct the detectives discover that 19 people and a whole bus have gone missing that day. They hear a tape of Baron Samedi calling for assistance with his car. Because the make and model were known, the car is soon found, so Nick, Hank, Wu and several other officers go to inspect the vehicle. In the trunk they find some Voodoo style items and Nick notices that the car has been dumped near a container yard.

Nick returns to Juliette's house, and she asks him how his day went. He tells her about the Cracher-Mortel and the zombies, and apologizes for not explaining everything very well as he is not used to telling people about that sort of thing. Monroe calls to say that Al is awake and Nick says that he has to go out. Juliette asks if it is Wesen stuff and when he replies in the affirmative, she says that she is going along, as she doesn't want to be locked out again.

At the spice shop, Nick questions Al and realizes that he was probably held in the container yard near the abandoned car. Nick gives Rosalee his key to hide, and then they all start making more antidote.

They head to the container yard and have a few zombies attack them, so they subdue them and inject them with the antidote, but more and more zombies start coming from all directions. Nick asks, "do you get the feeling we just walked into a trap?" Nick then leads the zombies away from their entry direction to enable Juliette, Monroe, and Rosalee to return to the car.

Baron Samedi then makes himself known to Nick, who climbs up a container and chases Baron Samedi. When he catches up, the two fight. The Baron knocks Nick down and tries to open the top of a container and Nick tackles him into it. As soon as they fall inside, the Baron runs off and hides. In the container Nick finds an empty coffin containing a passport in the name of Thomas Schirach with his picture. Nick then hears a voice and turns around to see the Baron woged. The Baron spits in his face. Eric meets up with the Baron later, saying Nick has a plane to Europe to catch. The two then look inside the coffin, where a pale dead-looking Nick is lying.

Nick's coffin is loaded onto a private airplane with Baron Samedi as the only passenger. Shortly after the flight begins, the Baron notices that Nick is attempting to escape from the coffin. The coffin springs open and the Baron spits on Nick again. Thinking it calmed Nick down, he turns around to return to his seat, but Nick attacks the Baron. Because of the noise created by the fight, the co-pilot comes to investigate. Nick then attacks him and enters the cockpit where he attacks the pilot, causing the plane to crash. Nick is unharmed by the crash, and heads into the woods. After a while he comes upon a bar, which he enters and when one of the patrons challenges him, he proceeds to attack anyone who doesn't get out of his way, or who attacks him. He leaves through the back door and continues through the woods until he hears a family arriving home in the near distance and starts heading toward their home.

Nick breaks into the family's home by smashing the front door. He hears a noise from upstairs and runs towards it. He starts beating in the door to the room that the family is hiding in. He is unable to enter as a bookcase has been placed behind it. He continues pounding on the door which attracts the attention of the pursuing Hank and Monroe. Just as Nick breaks into the room Hank and Monroe arrive and engage him in combat. Hank and Monroe lead Nick out of the house and manage to trap him under a hayloft, by having him fall through a weakened gallery floor.

When Nick breaks free from the room, he is confronted by a woged Monroe, a woged Captain Renard, and Hank. All three fight Nick, but Nick doesn't have much trouble against them. Juliette and Rosalee come into the barn and Juliette says Nick's name to get him to face her as she plunges the Piqure-Gigantesque containing the antidote into his stomach. Nick knocks her aside before she can depress the plunger and Rosalee rushes in to depress the plunger. Nick makes as if to attack her, but instead he collapses.

Nick is taken to the spice shop, where he is handcuffed to a bed and given another dose of the antidote.

Later Nick wakes dazed, confused and sore all over. He asks what he is doing there. Rosalee asks what the last thing he remembers is, and when Monroe mentions the container yard he remembers going there with the antidote, and then getting separated from the others before confronting Baron Samedi, falling into a container and finding a passport with his photograph. He says that he must have been knocked out and wonders why they brought him to the spice shop. From their reactions he realizes that something else happened, so he asks if he is leaving something out. Juliette explains that Baron Samedi infected him and she lifts his shirt to show the injection marks. Juliette tells Nick that he should come back to the house to rest.

While Nick is sleeping, his skin turns grey. Juliette wakes up and rubs Nick's face. When it is cold she panics and calls 9-1-1. Just before the call is answered, Nick wakes up and asks who she is calling. Juliette checks Nick's pulse and tells him he needs to see a doctor, Nick assures her he feels fine and goes back to sleep.

The next morning when Holtby and Bauer, two detectives from the Precinct, knock on the door to speak to Juliette, they explain that they are there because someone died during the bar fight and that Juliette was there with Captain Renard and Rosalee. While the detectives are questioning Juliette, Nick is in the kitchen, but his enhanced hearing allows him to clearly hear the conversation.

Nick decides that he is going to turn himself in for the killing and goes to the Precinct, where Hank tells him that he is on his own if he does this. Before he can do anything Captain Renard shows him the CCTV footage of the fight, and that the man who dies had attacked Nick with a knife. He also says that it is the fault of the Royals, as they had him drugged and if he turns himself in it will only benefit them. Nick meets Holtby and Bauer and they ask how he is feeling. He thinks about the bar fight, but decides to reply that he is doing fine before sitting at his desk.

Personality
In most episodes Nick seems to possess a keen sense to profile people quickly (even before the family's misfortune was passed to him), though it doesn't prove to be correct in the case of Monroe (this was however mostly due to him being distracted by his new Grimm abilities, which allowed him to see Monroe's Wesen face). Aside from his ability of prospection, he has a good amount of self-confidence that never crosses over into arrogance. This, along with his ability to stay calm and rational in difficult situations gives him an edge in coping with his new found powers. Nick's sheer bravery is incredible. Multiple times he's leapt into dangerous situations to save others, and even when faced with opponents who are at least his equal, he refuses to back down.

Nick has a keen sense of fair play and a good moral compass. Despite the many atrocities he sees every day as a policeman, it never blinds him to the inherent goodness inside all creatures. And because of this, he has taken it upon himself to not only fulfill his role as Grimm in protecting humanity from dangerous Wesen, but also to protect Wesen from those of their kind who are out to harm them, along with humans who may come after them for similar reasons. He is a loving and devoted boyfriend, and a loyal friend. He can however be ruthless when the situation demands it, and is not above using Wesen's fear of Grimms to his advantage, but only when the situation requires him to. Over time, due to coping with his Grimm duties, Nick has gotten more ruthless, and is now less worried about killing opponents, but only if they are a serious threat to him or others. Nick's temper has also increased, and he's become more prone to expressing and listening to his rage as well. Nick also shows he's a highly capable liar, able to make up believable stories on the spot to cover his Grimm activities, as the series progresses he gets more comfortable with bending or even out right breaking the law when he needs to do Grimm business.

Nick does not seem to know any foreign languages. He's been exposed to German, Japanese, Latin, and Spanish, and has been unable to read these languages without help.

Over the course of season one, Nick's confidence grew greatly. With each encounter with a new Wesen, his actions became bolder and more assertive, thus revealing his capabilities as a Grimm, though his abilities are triggered, like Wesen, under intense emotions. Amidst the chaotic events he has maintained balance as a detective and a Grimm.

Nick utilizes his role as a detective in numerous ways. He's come to rely on basic training in marksmanship and hand-to-hand combat, in which he displays proficiency, these abilities are likewise enhanced by his natural Grimm skills. Nick seems to wield some authority in the Portland P.D., as he has been seen giving orders in multiple episodes. As a result of his job it's easier for "law abiding" Wesen to trust him. Allowing him to work both sides. Ultimately he can centralize his investigative efforts, as a Grimm, with a team of vigilantes, to come up with strategies to combat crime in the Wesen underworld.

Nick has mastered his Grimm powers and has proven on multiple occasions he is an acomplished warrior, a skilled fighter, a highly capable hunter and a competent tracker, all skills that he requires to perform his Grimm duties.

Grimm Abilities
Nick possesses all the powers of a Grimm, which he regularly uses to combat evil and dangerous Wesen. His Grimm powers make him stronger and more powerful than any human, and many Wesen.

Superhuman Perception: Nick's powers as a Grimm give him the ability to see creatures in their true form when they get excited, annoyed, angry or careless. Nick is also superhumanly observant, allowing him to pick up on the most miniscule details that others often overlook.

Superhuman Strength: Nick's strength is significantly enhanced, making him much stronger than any man; this allows him to match the fighting prowess of many Wesen, the only exception so far being a Siegbarste. His strength has made him noticeably stronger than several more powerful Wesen, such as Jägerbar. Nick's skills are highly impressive, since he's been able to fend off Blutbaden, and hold on much longer than the average man when fighting a Siegbarste. He could defeat a Skalenzahne, something Monroe was unable to do. During a fight with a Mauvais Dentes, he held his own long enough for his mother to arrive and help him finish him off, while Mauvais Dentes usually have no trouble overpowering and killing their targets. When enraged and infected with Cracher-Mortel toxin, he was able to leave dents in a solid metal coffin without damaging his hands.

Superhuman Reflexes: Nick's reflexes are enhanced to great levels, allowing him to take on Wesen as fast as Schakale, Steinadler or Jinnamuru Xunte, although he is still at a disadvantage when facing Königschlange. While suffering from Cracher-Mortel toxin he still possessed these reflexes and could easily match multiple opponents as well as catch an object thrown at him in mid air without even turning to face it.

Superhuman Durability: Nick's durability is notable; several times he has taken blows from incredibly strong Wesen, and recovered in seconds. For instance, in a fight with a Schakal, the creature smashed a toaster against his head, yet he recovered in seconds. He even took a beating from a Siegbarste, and escaped with only a few bruised ribs.

Superhuman Agility: Nick's agility is enhanced allowing him to move with great speed and flexibility, in a fight with Reapers he acrobatically flipped over to dodge two scythes.

Superhuman Stamina: Nick's stamina is incredible; several times he's emerged out of heavy fights, and still seemed only mildly dazed.

Superhuman Speed: Nick is shown to be incredibly fast on several occasions when chasing others. He nearly always catches them, and (if in a group) he's often way ahead of the others in the chase (including some Wesen).

Superhuman Hearing: After the loss of his eyesight by the parasitic infection from the Jinnamuru Xunte, Nick gained the ability to hear sounds beyond normal limits. Nick is revealed to have retained or fully realized the ability when he closes his eyes/blindfolds himself after he gets his eyesight back. He later seemed to be able to access a lesser version, even with his eyes open as he was able to hear to movements of the nearby Taureus-Armenta. While suffering from Cracher-Mortel toxin, it appeared to be enhanced exponentially, as he was able to hear a conversation from much further away than before. He could still access the enhanced version of this ability after he was cured.

Superhuman Endurance: Nick's endurance is shown to be very high; he has incredible pain resilience, as demonstrate in fights with very powerful Wesen such as Mauvais Dentes. He can also hold his breath for a reasonably long time as he did when he was fighting La Llorona under the river. Later, it was noticed that after his infection and cure from Cracher-Mortel toxin, his heart rate and blood pressure remained completely stable even when he was running at top speed.

Eidetic Memory: Nick has been shown to have a very good (potentially photographic) memory. For example, when Monroe mentions Siegbarste Gift, the only thing that can kill a Siegbarste, he remembered that he saw some in the trailer and remembers seeing the rifle that is made for killing a Siegbarste. Nick is also able to remember the faces of the Wesen he's seen, and quickly learn minor details about them that often come back to help him.

Indomitable Will: As a Grimm, Nick possesses incredible will power, making him (like other Grimms) immune to powers of the Coins of Zakynthos, which are so strong, no man or Wesen can resist them.

Artistic Talent: He is also shown on a few occasions to be quite a good artist; this ability also helps him in hunting the Wesen, when trying to identify them. Nick is revealed to have inherited his abilities from his mother, who in turn inherited them from her Ancestors.

Combat Skills: Although he also possesses police training, as a Grimm, Nick possesses a natural aptitude for fighting, particularly with Wesen. This also means he's naturally skilled with medieval weapons, he mastered both the Flail and the Lance after only holding them for a few seconds, and was able to master his Grimm weapons after merely a few tries. Nick is also a capable marksman, and rarely misses his target.

Blood of a Grimm: As a Grimm, Nick can use his blood as an offensive weapon, as the blood of a Grimm, it kills the Wesen part of Hexenbiests (and possibly other Wesen) thus turning them human, and robbing them of all their powers.

Relationships
Monroe - After an encounter with reformed Wieder Blutbad Monroe, he gained an unofficial partner. At first Monroe was unwilling to help, due to tensions between the two's ancestors, but he soon came to accept their relationship, and the two formed a strong friendship, both saving the others life at least once. As it defies the status quo, the Reapers and the Royals are very displeased by the idea of one of the creatures helping a Grimm. Although Monroe has been threatened, beaten, and had an assassin sent after him to keep him from helping Nick, he remains a true and loyal friend, helping out with information and back up. Monroe was for a long while the only person in whom Nick could confide about his Grimm activity, and Monroe is aware of Aunt Marie's trailer. However, Monroe and Nick make sure that it's not obvious that the two of them are working together, especially to other Wesen. Following Nick's problems with Juliette, Nick now lives with Monroe, who gave him his spare bedroom, until it is all worked out.

Hank Griffin - Nick has a good relationship with his partner Hank Griffin, having been friends with him long before Nick discovered his heritage. Hank was often at a loss to understand how Nick is able to "see" what he does in people. Nick even considered telling Hank his secret, but for fears of it driving him insane he didn't. Following Hank's discovery of the Wesen world and Nick being a Grimm, their relationship greatly improved, and Hank manages to aid Nick in his off the record activities as a Grimm. He is one of only four people (the others being Monroe, Rosalee and Juliette) that Nick trusts with the knowledge of the trailer.

Sean Renard - He has a good and mutually respectful relationship with his superior, Captain Sean Renard. The two seem to get on fine, and Nick trusts Renard's judgement and leadership. He was not aware until that Renard actually protects Nick to the best of his abilities, or of Renard's true identity or heritage. However, recently he has discovered that Juliette was seeing Renard, and he briefly fought him in, before discovering his true identity and his motives. At the spice shop, Renard also told him that the potion Nick was about to take was similar to the potion that he had used to save Juliette, and it is causing their mutual infatuation. Following which, the two keep a relatively friendly relationship, and easily work with each other. However, Nick is still somewhat weary and distrusting of Renard, knowing that he keeps a lot of secrets and is playing a lot of games.

Juliette Silverton - Despite Aunt Marie's warning, Nick has stayed with Juliette. They have a close, and loving relationship, but Juliette is getting very suspicious about the various goings on since Marie's visit. Notably, after their refrigerator was worked on by an Eisbiber. Bud, the repairman, told several drinking buddies that he saw a Grimm, and the curious beaver-like creatures have been pestering Nick and Juliette by spying on them, and even having their house egged by two Eisbiber children. After Juliette loses her memory of Nick due to Adelind's curse, there is a great strain on their relationship, and despite Nick's best efforts, she hasn't been able to fall back in love with him. However, with help from Monroe and Rosalee, Juliette's memories return, causing her to be overcome with guilt over how she acted. She began to understand what Nick had been trying to tell her, which led to Monroe, Rosalee, and Bud showng her their wesen forms. She learned to work through this and regains romantic feelings for Nick again. In addition to now knowing he's a Grimm, Juliette has stated that she has "a lot to learn" stating she wants to learn more about the wesen world (and possibly explore the life of a Grimm), thus allowing them to rekindle their relationship.

Bud Wurstner - They first met when Bud was fixing Nick's refrigerator, and in a moment of stress, Bud woged upon realizing Nick was a Grimm. He ran off terrified. Bud later caused Nick several problems by telling his drinking buddies about Nick. This led to other Eisbibers trying to see him. Nick went to confront the Eisbibers and found Bud there. Initially terrified, he was calmed slightly when he learned Nick didn't plan to kill him, and quickly agreed to have everyone stop. Afterwards, Bud generally acted subservient to Nick, to make certain he didn't have any cause to harm him. This annoyed Nick slightly, as he had trouble justifying it to Juliette. It was only when Nick got involved in the Eisbiber/Hässilech feud, that Bud realized what a good person Nick was, and the two formed a friendship. Their friendship got stronger after Nick saved Bud before Ryan Smulson could kill him. Despite this, Bud is still somewhat afraid of Nick, especially when Nick goes through emotional problems.

Rosalee Calvert - Upon first meeting, Rosalee was originally wary due to Nick being a Grimm, but the two quickly warmed up to one another. Nick trusts Rosalee and considers her a friend, he often asks for her aid on matters that involve alchemical matters.

Kelly Burkhardt - Nick loved his mother, but upon discovering she was still alive, and the fact that she never told him, he was deeply hurt. However the two soon managed to patch up there relationship, and Nick accepted that she had to leave him, and hoped to see her again soon.

Adalind Schade - Nick and Adalind deeply dislike each other. Their rivalry originally started when Adalind tried to kill Aunt Marie. Afterwards, Nick was forced into guarding Adalind when her life was threatened by a Mellifer. Not understanding the world at the time, Nick chose to save her. However following Adalind placing Hank under a spell, Nick's opinion of her dropped considerably, and he grew to hate her. Their tensions finally met a breaking point, and the two fought. In the fight, Nick tricked Adalind into swallowing some of his blood, thus turning her human and robbing her of her powers. Adalind in retaliation cursed Juliette, causing her to enter a coma. Nick now hates her without redemption.

Aunt Marie - As he was raised by her, after his parents died (or rather appeared to in his mothers case) Nick deeply loved his Aunt, and was greatly hurt by her forecoming death. He was also shocked when he learned how much he didn't know about her, and was greatly saddened when she died.
