Cold Blooded

"" is the seventh episode of Season 3 of Grimm and the fifty-first episode overall. It first aired on December 13, 2013 on NBC.

Synopsis
Deep in a sewer, a figure trudges along the passageway with a backpack. It stops in front of few barrels of metallic objects, then dumps the contents of the bag into one.

The new prince Victor - Sean and Eric Renards' cousin - talks to Adelind, expressing his devastation at Eric's demise. He seems geniuinely determined to avenge his late cousin, despite Sean later stating that Eric never trusted Victor. Putting a hand on her shoulder, he orders Adelind to put together a list of all the everyone in Portland that may have had something to do with Eric's assasination.

A burly man - later known to be Gregorak - smashes the windows of a house and breaks in, stuffing all sorts of metallic things into his backpack. He pauses as he hears the owner of the house - Scott Himber - approach the front door. Scott is on the phone with his mother, distracted as he enters the house. Only after he hangs up does he realise that the house is messed up and that the thief is still in the house with him.

He runs to the kitchen and grabs a knife to defend himself. Gregorak attacks and quickly disarms him - literally.

Nick and Hank are called in to investigate Scott's murder, and are mildly shocked to find that his arm has been ripped clean out of its socket. Hank expresses his doubt that the murderer was "somebody" human. The murderer has left huge bootprints with the blood, and Nick is worried that it is a Siegbarste again.

The duo return to the precinct and find out that there have been many robberies recently, none of which have had witnesses until now. The split up; Hank checks the pawn shops and Nick goes off to retrieve the report on Scott's body.

Harper has a lot to say about the corpse - the arm had been bitten off, powerfully crushed. Scott had had his neck broken and several fractures - "whatever got a hold of this guy gave him a good shaking."

Meanwhile, Jimmy, a sewer worker, is lowered down into the sewers by his partner Charlie to investigate a blockage. He hears a sound and goes to check it out. Above-ground, the crank attatched to Jimmy's harness begins turning furiously. Charlie shouts at the workers to haul Jimmy back up - only to find him mauled badly and missing a leg.

Sebastian enters a warehouse and is met with a Sean's gun, until Meisner assures Sean that Sebastian is alone. Sebastian vehemently recriminates Sean's suspicions that Sebastian had set them up. They speak about Breslau and the arrival of Prince Victor. Sean lets on that he doesn't know Victor, but he knows Eric never trusted him. They then discuss a "meeting" with Fornay and Tavitian, the latter of whom is being suspected of Eric's murder.

Nick and Hank are called to the scene of Jimmy's death. A medic remarks that the only time he'd ever seen anything like it was when a hiker was mauled by a bear in the forest. Wu brings up the urban legend of alligators in the sewers. Nick, Hank, Charlie and Wu go down into the sewers to take a closer look; despite the latter being clearly bothered by the idea.

The team finds blood smeared on the walls, and Wu stays behind to pick up backpacks they found in the water. Nick tries to listen for movement, but his Grimm hearing is overwhelmed by the vehicles passing overhead. Meanwhile, Wu finds something lodged underwater and screams upon finding that it's Jimmy's leg.

Back at the precinct, Nick and Hank research and find that the items in the backpacks match the robberies reported around the neighbourhood. They doubt that the sewer murder could be linked to Scott's, until Wu comes back with news that they found Scott's gym card in one of the packs.

They also discover that the bitemarks on Jimmy's leg are alarmingly similar to that of an alligators. Wu comments that "alligators don't rob houses", at which Nick and Hank exchange a look.

At Monroe's house, they discuss the possibility of a Wesen that "lives underground and can rip limbs like taffy". Monroe tells them that it's most likely a Gelumcaedus, and cautions them to know what they're dealing with.

Nick wants them to all go to the trailer but Monroe protests that he's making dinner. He eventually suggests  that they bring the books over, when Nick and Hank begin to debate over whether "Gelumcaedus" starts with a 'G' or a 'K'.

Sebastian returns to the warehouse and is met again with guns. He informs Sean and Meisner that Fornay wanted them there now.

Nick, Hank, Monroe, Rosalee and Juliette lounge about in the living room, each with a Grimmoire. They learn that Gelumcaedus were an ancient species, hired to protect aquaducts in the Roman Empire. Juliette finds a journal in which a Grimm's arms were torn off in a fight with a Gelumcaedus - escaping the wesen's grip is virtually impossible. This led the Grimms to procure a vambrace, a metal-leather arm brace. Nick states that he has one of those in the trailer, to which Hank sarcastically scoffs. They decide that they have to return to the sewers, but not as cops.

The duo do more research on the sewers and acquire a map. They realise that the tunnels intersect and that the Wesen is using them as a way to get about the city.

In the trailer, Nick digs out the vambrace from the weapon's closet. Hank declines Nick's offer of letting him wear it, preferring a rifle. Nick decides to wear it in honour of his ancestors, and surprises both of them when a blade shoots out of the brace.

Nick and Hank enter the sewers again. It's quieter now, and Nick manages to hear and see the Gelumcaedus run past. They lose him, however, as Nick is confused by the footsteps - it sounds like the Wesen is in three places at once. Hank dismisses it as an echo and they continue on. Nick later catches the sound of ticking - a lot of ticking - and discover a door in the wall of the sewer.

They enter and find the Gelumcaedus' hideout, complete with a bed and hundreds of thousands of clocks. Hank is attacked from behind by the woged Wesen, and is thrown into a shelf. The Gelumcaedus manages to bite down on Nick's arm, but the vambrace saves him. Together, Nick and Hank take down the wesen, forcing it into a corner. It woges back into its human state - revealing himself to be Gregorak. "Decapitare," he snarls at Nick, clearly taken aback.

Sean, Sebastian and Meisner reach a farm where they are greeted by two men, who tell them that a "trial" is ongoing. They hear pained shouts in the distance, and Sean comments that they must have reached a verdict. Entering a barn, they see Breslau - the man who set up the "safehouse" for Sean - being interrogated violently. The interrogator beseeches Breslau to tell him "what's her name", not wanting to hurt him more than necessary. Breslau complies and is led outside.

Sean shakes hands with the interrogator, recognising him as Claude Fornay, a man who saves Sean's mother once. Fornay comments that he was rewarded well for it. A gunshot sounds outside - Breslau has paid for his betrayal.

Gregorak is chained in the precinct's holding cells. Nick and Hank attempt to get a confession from him, but the wesen denies them one. Later that night, Nick calls Monroe. Rosalee picks up - Monroe is knee-deep in a clock - and they tell him that "Decapitare" is latin for "he who decapitates" - another name for Grimm.

Nick realises that the times of the robberies overlap - Gregorak is not working alone. He informs Hank via cellphone, but as soon as Hank hangs up, he is attacked from behind by a Gelumcaedus. Hank is bound, gagged, and dragged into the sewers.

Nick receives a call from Hank's phone, but it is instead a stranger on the other side. The stranger demands Gregorak back, and threatens to rip Hank into pieces. Distressed, Nick demands to talk to Hank but the man hangs up. Nick gets Gregorak and brings him to the sewers, where he receives another call from who appears to be Gregorak's brother, to leave his gun in the car - which Nick surprisingly obeys.

In the sewers, Gregorak comments on how he had been frightened of the "Decapitare", which his grandfather used to scare him with. He adds that Nick doesn't seem scary anymore.

Andre waits deep in the sewers with an immobilised Hank. He demands that Nick frees Gregorak, and Nick again complies without caution. They exchange hostages, and Nick frees Hank while Gregorak informs Andre about Nick being Decapitare. The brother decide that they cannot allow Nick and Hank to escape alive. Hank, now free, yells at Nick that there are three brothers.

A Gelumcaedus attacks Nick from behind as Andre and Gregorak woge. Nick manages to knock down the third brother as Hank struggles to get free. The other two brothers lunge but Andre is quickly overwhelmed. Nick slits his throat swiftly with the vambrace's blade, using the corpse as leverage and stabbing the unnamed brother too. Gregorak pins Nick to the wall but Hank hits him with a pole and the duo once more subdue him. Gregorak is devastated by his brothers' death, but Nick and Hank are apathetic.

Adelind whispers to her baby, seeming to imagine what her child will call her in the future - despite her having already sold it to the Hexenbiest. Victor watches her from a hidden camera, realising that she is with child.

Nick hangs the vambrace back into the trailer's closet. "Decapitare," he murmurs to himself. "I kinda like that."
