This just occurred to me sideways, and the more I think of it, the more I like the idea.
* Joshua said that God didn’t see the apocalypse as his problem. He wanted the Winchesters to butt out. Crowley found himself in a tight spot because of the Winchesters’ involvement. And the apocalypse all worked out to his liking in the end, but he still hates the Winchesters for getting their chocolate in his peanut butter.
* Joshua also said God was on earth, while Crowley was hiding out there.
* On a theological level, I never understood why God wouldn’t control hell as well as heaven. Why would the devil punish sinners? They give him power. God, on the other hand, would want to see sinners punished for their transgressions.
* Crowley speaks and understands Enochian, which makes him at least angel-level. But he didn’t understand how angels worked and was trying to hack their OS. Understandable, given how angels (starting with Cas) have found themselves starting to form their own allegiances and make their own decisions.
* Metatron wrote the tablets and disappeared to earth after leaving the tablets for humans to find (that was a very important part of his goodbye note). What if Crowley needs the information on those tablets to regain his supremacy over the universe? A God fallen, perhaps.
* Another theological question, why should God necessarily be a good guy? If anyone gets license to play against the rules, it’s God. He gets to decide what deserves killing or maiming or torture, that’s his job. But he also shows uncharacteristic mercy sometimes, he moves the other pieces around on his own personal chessboard, and he’s ALWAYS ahead of the game.
I’m not saying the writers will do this, although I think the seeds of Crowley being Not Who He Appears to Be are certainly planted. But I like the concept nonetheless. There’s at the very least some fic fodder there, so someone write it for me. :)
