Okay, if Castillio is Lucifer he's having Sam stop using his power why? Is it a threat to him? The yellow-eyed demon bred these kids in an overthrow attempt and each one's power is able to thwart Lucifer in some way.
It's possible now that I think on it. I don't like it but it could work. So the final is the revelation of Castillio and Sam's battle with him. It doesn't explain why he puttting Dean on these wild goose chases to stop himself from being released, though.
I agree that I like him being an angel much more, as you say, opens the story up much more. We've seen them battling demons, without reward for so long, not let's see the other side of the coin and how they work and, just maybe, how different they aren't.
