Human souls that go to Hell inevitably turns into demons. Cool concept, though I question the legitimacy of this statement from Ruby.

I don't see how Ruby found out that Azezeal or the 7 Sins were human once when they are millennia old while she is a few centuries old and seem to be rather low in the food chain. I do believe that most of the demons were once human but I also think there are true demons.

Also, she could be lying.

The implications of this for Dean are kind of awesome. However, I don't think the demons has thought the whole Dean = Demon thing through. I mean a Demon Dean with all that training and with his own agenda is damn dangerous.

Sam is awesome in this episode. The End.

The gender issues in this episode? It makes me want to bash my head into a wall; most of the time I find SPN does rather well in its handling of gender issues, this episode makes me hurt. It is something I’m not going to touch until I have had a pot of coffee and some serious meditation.

I conclusion; welcome back boys, I have missed you guys.
