Sacrificing himself to save Allison, Chris hands himself over to Jennifer. The group discover that Jennifer is holding her victims in the root cellar. Scott and the Alpha pack hunt down Ms. Morrell; Deucalion injures her with the blade in his cane. Peter tells Derek that as an Alpha, he can heal one of his own, even at the brink of death. Choosing family over power, Derek heals Cora, losing his Alpha powers in the process.
