Conspiracy theory
Steve has information that John Roberts has been replaced by an alien robot. Though not quite so good looking as the others I've seen, I think it's probable he's actually a cylon.
The good news: Jimmy Akin says it's okay with God to "lock and load" on robots. The bad news: the theology gets murky if the robots have a soul, so we'd better send in Dean, since he's an orthodox atheist. Then again, even Dean might have a problem with the idea.
