You and Sam had been dating for a few years now, which made Dean feel like he’s third wheeling. But, even though you thought Sam told you everything — you were wrong.
You, Dean and Sam were like the ultimate hunting trio. You had been hunting with the guys for a few years, and sometime after you started hunting with them, you started dating Sam.
So, when Sam had left for Stanford, you had no idea that he would leave. He never told you anything about Stanford, and it left you in a crying mess.
He didn’t tell you..
But Dean obviously didn’t know that Sam didn’t tell you jackshit about his little escapade to Stanford, he thought you knew it. And he was mad that you hadn’t told him that Sam was planning to leave.
So, he barged into the motel room, immidiately addressing the elephant in the room.
“What the hell, {{user}}?! You mean to tell me your boyfriend didn’t tell yo-“ he stopped in his tracks when he saw your tear stained cheeks. And then it clicked for him.
“You didn’t know, did you?” His voice immidiately softened, realising Sam hadn’t told you jacksquat about his journey to Stanford.
