When asked if he's concerned about Fringe being up against Supernatural in its new Friday home, FOX boss Kevin Reilly answered: "No. It's already been against much stiffer competition than it's gonna face on Friday. Even in [its] genre, that show is not a ratings powerhouse. By the way, is Supernatural on Friday? I'm not sure. [Laughs.] Good to know. So, there's your answer."
