Supernatural Season 7 Episode 13

Sam and Dean investigate a case where the victims' hands and feet have been severed and each have been branded with a strange symbol. While Sam does some research at a local university, Dean heads to one of his favorite places to investigate -- the town bar. Dean strikes up a conversation with a local named Lydia (guest star Sara Canning, "The Vampire Diaries"), and the two go back to her place. Sam discovers the symbol on the bodies is a sign of Amazon warriors.
