Castiel as a hunter. Really, I like this concept more than I should. It doesn't help facts when I think about one of the last episodes where Cas uses the gun on the Croatoan-infected who was hurting Sam.

Oh no. Please do not tell me Dean had such horrible survivor's guilt that he... might have... ended it. Please, no.

I can't believe this story is near the end, either. It's been a good story and had its moments.
