It looks like the prophet from the last episode of Supernatural, "The Monster at the End of This Book," will be returning. Chuck (Rob Benedict) wrote a novel called Supernatural inside the show, Supernatural.
Somehow, this prophet was able to see the Winchester boys' actions and future actions in his dreams. As a result, it let the writers of Supernatural have a lot of fun poking fun at themselves and their online fan base!
If for no other reason than that, we're thrilled to hear Ausiello Files confirm that Chuck will return on Supernatural.
