I have a hard believing He won't show up at some point, and what would be the point of having Him show up if He didn't do anything?

But isn't one of the ideas about God that he sets everything in motion and then watches how it all plays out? He doesn't interfere because this is all one huge experiment? The only time to act would be if his creation was destroyed and he wanted to go for another iteration.

And yeah he's already tweaked things a little but I still don't think he's going to make any game changing plays. Obviously now I've typed this up Eric Kripke will prove me wrong in either a stupendously fantastic, or completely pathetic, way. *lol*
