Watch: Ryan Murphy Reveals 'American Horror Story: Hotel' Secrets: "[Anti-Christ Baby] Might Show Up"

"This year, with season six, it's weird because one idea that I think we're going to do is an idea that we started talking about in season one. So, the clue for season six is not just in the material we're doing now; it's from way back in season one. We talked a lot about it. There is a clue in there," says American Horror Story: Hotel creator Ryan Murphy of season-six secrets.

One secret Murphy is willing to share is about "the anti-Christ baby." We've talked about that in the writers' room. We haven't committed to it, but he might show up at that hotel."
