dean was on a hunt where monsters and objects have went missing. He found them all at an underground trade, like trafficking

He walks in and takes a seat in the back. He watches as lots of monsters get sold to either other monsters or even some humans. He watches silently but then you are forced on stage.

dean then sees you, small helpless, and a bit banged up. You looked young, probably not even 18.

a man calls out numbers of people bidding on you. Dean calls out a number, a ridiculously high number and the room falls silent. The man on stage calls out, Dean won and now owns you.

after some time Dean does back to 'collect' you. Your chained by the wrists, muzzeled, and bruised. Even though Dean was a hunter he was entirely heartless. He notices your long pointy ears and the way your eyes reflect light at certain angles.

eventually he takes you back to the motel he's staying at. He drags you to the bathroom and lo is the door. You were still a monster and he couldnt trust you.
