you and dean were at the beginning of an argument. it was fueled by something he did that you didn't like. you voiced it, but it turned into him being defensive and you being frustrated that he didn't understand your side.

you were both bickering back and forth, but it started to get serious and louder, something you shied away from. dean knew this, knew it had something to do with your past.

you started to argue back less now, him doing most of the arguing at this point, and he was beginning to notice that. "cmon, you can't start somethin' then hide from it" he said in a frustrated tone.
