Noshiko explains the nogitsune took Lydia for her banshee powers.
Lydia stands in a hallway listening to screams. The nogitsune-possessed Stiles walks towards her and she tries to get away. She asks why she's being held as he approaches. Lydia refuses to say anything but the nogitsune says she'll be screaming.
Kira doesn't want to sit and wait but Noshiko has other plans. She wants to teach her the game that Scott saw Stiles and the nogitsune playing. Kira thinks it's a waste of time but agrees when she learns it could save everyone's lives.

They take Meredith to Stiles' jeep but she doesn't know who Lydia is.
Argent shows Allison how to use the silver to make bullets. She suggests making arrowheads since the bow is her weapon. Allison tells him she loves him and is proud of him, and kisses her head before leaving the room.

Stiles, Scott, Isaac, Allison, and Kira all arrive at Oak Creek at the same time. Scott reminds them of the time they all came together to save Malia and knows they can do it again for Lydia. Inside they confront Noshiko, who says Stiles can't be saved. She tried the same thing 70 years ago and it didn't work. Noshiko knows that Kira is now the fox but she must still bury her demon.
The nogitsune says he brought Lydia so that he would know when his death was closing in. As he says this, he pulls Noshiko's blade out. The Oni surround him and he snaps Noshiko's blade.

Allison asks him to tell Argent and then she dies. Lydia screams out over an unconscious Stiles.
