 * Who will be the Big Bad of Supernatural Season 10? –Tom Would you believe it’s… Sam and Dean? As the Winchesters battle their inner demons — literal and figurative — the show “be introducing, over the course of the season, characters that are very, very, very personal to our main characters,” executive producer Jeremy Carver previews, “and that’s all going to start to snowball into, ‘You are who you are,’ and having to deal with all this and drawing some lines. Of course, there’ll be Bigger Bads that emerge, but the central focus of the season is really on these personal arcs.” BONUS SCOOP: Carver reveals, “You will most definitely see Charlie’s (played by Felicia Day) return from Oz.”
