"And you didn't think it was something I needed to be told about, instead of woken up in the middle of the night by a strange man in a trench coat by my bed? Not exactly comforting." Then he looked at Castiel. "He looks like an insurance salesman.. or a Jehovah's Witness dressed like that."
when Dean pulled his shirt up Sam's brows raised. "How do you know it was him and we aren't being taken for a ride?"
Sam slumped til he was sitting on the foot of the bed. "I wasn't asked about doing any mission for anyone. And to be honest you guys haven't exactly been helpful over the years. Now you wanna come knocking on our door to assistance? Where the hell were you when he was being used as a hellhounds chew toy? Or when Azazel was gathering up his children? So pardon the hell out of me if I'm not so eager to jump on board the holy mission train."
So he felt a little bitter. Years and years of praying and believing to no avail and now all of a sudden a supposed angel was in their hotel room calling in a favor that Sam didn't feel either of them owed. The way he saw it, even if this angel had yanked Dean out of Hell, it was owed to the both of them after all the things they'd done over the years.
