Episode 9 : Witch Hunt

This episode will reveal a surprising origin story for Ruby (Katie Cassidy), and also see her working with Dean.

Episode 10 : Dream A Little Dream of Me

We learn how Bobby got into demon hunting, and also see more of how Dean (Jensen Ackles) feels about going to Hell. Creator Eric Kripke says that, “Something big happens to him that makes him realize he desperately wants to live and he desperately doesn’t want to go to Hell.” Bela (Lauren Cohan) also returns in this episode.

Episode 11 : Jus In Bello

Ruby will attempt to perform a spell that requires the heart of a human who is pure and innocent. Agent Henriksen from the FBI descends on the small town of Monument, Colorado and captures Sam (Jared Padalecki) and Dean. They spend some time in the slammer.

Episode 12 : Mystery Spot

An episode reminiscent of the film Groundhog Day, which finds the boys repeating the same day over and over again. Eric Kripke reveals, “Sam basically wakes up every day and it’s the same day and Dean dies at the end of every single day. It’s actually quite funny.”
