It might also be the first three and Lucifer. Technically, he used to be an angel. OR they are trying to explain his fall with the fact that he never had direct contact with God, therefore he lost faith and grew wrathful. I like your theory, that Uriel saw God and Castiel hasn't. That would explain so much.

And despite how the other fans are whining, I want Anna back. I loved how she was with Dean, the way they clicked. She told him so many things he just needed to hear, about forgiving himself and how he wasn't the only one who felt alone when he was given orders and tossed to the wolves by his father. I want to see their relationship grow in whatever direction it decides to.

Question: why does everyone slash Dean/Castiel but hardly anyone can get behind Dean/Anna? *sighs*
