Synopsis
The masked men get out of their truck and walk towards the spice shop. Inside the shop, Elizabeth goes through the things that Adalind had to go through to make the Verfluchte Zwillingsschwester potion work. Suddenly a brick flies through the window and the masked men drive off. On the brick is a. Elizabeth says it's a warning and Monroe says it's because he and Rosalee got married. Elizabeth says some Wesen are against mixed marriages. Elizabeth then tells them to just board up the window and get back to work if they are interested in Nick becoming a Grimm again.

Nick is making dinner at home when Juliette comes into the kitchen. Nick says dinner is ready when she is and Juliette goes to get Trubel. When she opens Trubel's door, she finds no signs of her. Juliette calls for Nick to come upstairs. They look around the room and find that all her stuff is gone except her chess piece.

At the spice shop, Elizabeth continues to make the potion. Rosalee goes to the back room to get an ingredient and Monroe follows her. He tells her no matter how long everything takes, once it is over, they are going to have their honeymoon.

Elsewhere in Portland, Keith Harrow drives up in front of a house. Inside the house, David Fisher is playing with toys until his mom, Sara tells him it's time to get ready for bed. Sara looks up and sees Keith standing at the front door. She tells him he can't be there and he says he wants to see his family. She tells him he is drunk and that she isn't his wife anymore. He starts to get mad and pounds on the door. She tells him not do that and runs to grab the phone to call the police. Keith breaks in the door and hits Sara. David comes into the room and pushes Keith, telling him to leave his mom alone. Keith tells him to go to his room as this is between him and Sara. David says no and Keith woges into a Siegbarste, and throws David to the ground. Sara grabs an item from a table and hits Keith in the back of the legs and then his back. She and David run to their car and drive off. Keith screams "if you don't come back, I'll kill us all!"

At the hospital, a nurse directs Sara's brother, Ben to her room.She also lets him know visiting hours are about to end. Once he gets to her room, Ben asks Sara if she called the police. She tells him she didn't have time, but the doctors did. He asks her how long she has to stay in the hospital and she tells him overnight because she has a concussion. Ben goes and checks on David who is drawing and asks if his step dad is the one who hurt his wrist. David stays quiet and the nurse comes in to tell Ben visiting hours are over.

Nick goes to the trailer and finds Trubel's bags. She soon comes in and tells him she had to make sure he wasn't followed. She tells him she didn't tell him something and then tells him about Chavez kidnapping her and what Chavez said to her. She apologizes for not telling him sooner because she was afraid the group Chavez talked about would hurt him and Juliette.

At the spice shop, Monroe tries to play down the threat of the wolfsangel, but Rosalee says he's not helping. Elizabeth then says they're done for the night and tells them to go home and get some rest. Rosalee asks what about her and Elizabeth woges, and says she won't be done for awhile.

Ben is at his synagogue where he gets out an old scroll and takes clay out of a jar. He then begins praying in Hebrew.

Keith comes out of Sara's house with a bat when he hears dogs barking. A muddy looking muddle suddenly appears at his feet, and a creature arises and engulfs him.

Nick and Hank arrive at Sara's house and Wu leads them to Keith's body. Nick says it looks like there is something coming out of every orifice and M.E. Bindra says she thinks it's clay and guesses ultisol based on the reddish color, but notes that it's not native to the Northwest climate. Keith's brother, Nate comes across the police line and sees his brother's body. Nate says if anyone killed his brother, it was Sara because she hated him. Nate goes with an officer to take down his information and Hank tells him they will call when they know more. Hank tells Nick there's no way Sara is strong enough to do what happened to Keith unless she is Wesen. Nick asks what kind of Wesen would use clay and Hank says they need to talk to Sara.

At the hospital, Ben tells Sara that he isn't letting her go home unless Keith is in jail. Sara says he never stays in jail and Ben tells her she and David can come live with him. She says he'll still find her. Nick, Hank, and Trubel arrive. David goes with Trubel just outside the room so Trubel can watch to see if Sara woges. Nick lets Sara know that Keith's body was found and Hank says that they are investigating his death as a possible homicide until they know the cause of death. Sara tells Nick and Hank what happened the night before while Trubel talks with David. David tells her that Keith is who hurt his wrist because when he gets mad, a monster comes out. Nick and Hank come out and Trubel tells them what David said.

At Sara's house, Ben grabs some of the clay from the ground, looks at it, and then heads to his car.
