Alphas, Derek and Peter try to find a way to save Cora, while Allison, Isaac, and Stiles discover that Jennifer has named Chris Argent as her last sacrifice, since he is also a Guardian. Sacrificing himself to save Allison, Chris hands himself over to Jennifer and is taken. With the help of Lydia’s drawing and Deaton, they discover that Jennifer is holding her victims in the root cellar. Peter tells Derek that as an Alpha, he can heal one of his own, even at the brink of death, but at the cost of his status as an Alpha.
