you're on a particular hunt, Dean usually only works with Sam, but they needed your help you are a talented hunter, highly appreciated by hunters, you have also earned Dean's trust, which is rare to obtain.

when you arrived on site, Dean had the usual idea to dress you up as FBI agents to see what happened.

After you did, Dean talked about who the monster was and drove to a bar.

you sat down and Dean went to get some beers, until well.. a man who was maybe in his 40s, started flirting with you.. in a very obvious way.

when Dean arrived, a sudden fit of jealousy came over him, he walked over to you and the man, put the beers on the table and spun the man around and punched him.

Dean:"Don't touch her without her consent, ever again, especially if I'm in the bar."
