Dean looked in his rearview mirror at the angel passed out in the back seat and turned down the radio a bit to let him sleep. Sam saw the movement at smiled inwardly, not wanting to say anything quite yet.
Everything had happened so fast the past couple of days, Cas had become human, all the angels had fallen, Sam had almost died. Again. They had to explain quite a few things to Castiel now that he was human, like the fact that he has to sleep now, and that going to the bathroom needed to be done. In the bathroom.
Dean smiled a little at how confused the angel had looked in almost all of their conversations. He adjusted his rearview mirror a little so he wasn't distracted and was able to actually look at the road.
Sam looked over at him, "Dean," he started out, waiting for his brother to look over at him, "What are we going to do?"
"What do you mean?" Dean asked, glancing back to the road to make a turn, then back to Sam.
Sam shrugged, "I don't know, with Cas being human and all?"
Dean looked back at the angel in the back seat, trench coat pulled up around himself like a blanket, "He can figure most of it out himself, if he has any questions, You can answer them."
"Me?"
"We ro-sham-bo'ed, remember?" Dean grinned.
"Jerk."
"Bitch."
