Our special guest is Ty Olsson (Supernatural's Benny)
Sam (Jared Padalecki) asks a hunter named Martin (guest star Jon Gries) to keep an eye on Benny (guest star Ty Olsson) without telling Dean (Jensen Ackles). However, when Martin tells Sam there was a vampire kill and he thinks Benny is responsible, Dean defends his friend. When Martin decides to take things into his own hands, things get messy and Dean is forced to make a very hard decision. Nick Copus directed the episode written by Daniel Loflin.
