Repo Man - S7.E15

Four years ago, Sam and Dean helped a woman named Nora exorcise a demon that was systematically killing women in a small town. They managed to save a postal worker, Jeffrey, while vanquishing the demon, but now it seems the black-eyed monster has reared his ugly head and returned for a second helping. The brothers visit Jeffrey, who has been locked in a psych ward since the incident, to see if he can remember any of the demon’s plans while he was possessed.
