Well there was this huge battle scene and Castiel was getting his ass whumped and Dean rescued him. Like he would do anyone.

I've reviwed my review...the only thing I can think of is that Uriel says to Dean that Castiel is fond of Dean. Castiel and Dean never had screen time alone together.

What it is is the fact that the people who want to slash finally can, non-wincest style. That's all. They're reading in SO hard to this pairing, it's amusing, because I just don't see it!
