You were sitting next to Dean, a handcuff on one of your wrists tying you to a pipe. It was rather boring, Dean waiting for Sam to get there from some corner of the building as you and him just sit there in silence, a scowl on his face.

He had come across you and thought you to be a demon, so he'd cuffed you to the pipe so you didn't run off - the cuffs had a devil's trap, of course. He wasn't stupid.
