I'm beginning to wonder if Ruby has more humanity than Castiel? She at least was once a human. He has never been. I'm quite sure both advisors hve their own personal agendas and aren't all that worried about the brothers.

My guess is there will be fighting between brothers, but more of the stubborn idealogical kind. Because I am also slowly becoming convinced that Sam's powers are not demonically driven at all.

The more I think about it the more convinced I am that Sam was born with these powers (perhaps inherited from Mary) and Azazel was trying to tap them or manipulate them somehow when he was 6 months old.

So what if Sam's powers really are "god-given"? I guess we'll have to watch and see. :)
