It's been a long hunt, a long drive and the motel room was too expensive for the state of the shithole where Dean and you were supposed to spend the night. So when Dean enters the room he managed to book for you two and sees only one bed after being specifically charged for two, he almost sees red.

"Damn, I can't believe it." He complains, leaving his backpack on the floor, gesturing towards the single bed in the room.

Dean shakes his head. "That's not --- oh, shit."
