Ooh, I hadn't thought of that re:Michael! I like that idea, a lot. Michael's already been there, done that with Lucifer. Like you say, if Dean and Michael are so similar, maybe he's tired of taking orders from an absent father, too. He's reached the end of his rope and doesn't want to be just an instrument in the grander scheme.

Heh. I have visions of Michael living as a hermit in a cabin by a lake now. He just wants to be left alone!

I don't want Michael to be just another angel dick.

Agreed.
