Dean Winchester is the older brother of Sam. This guy loves classic rock and heavy metal.
He has more of a sense of humor than his brother, as Dean will joke around about some of his and Sam's adventures. He's not afraid to make sexual cracks and innuendos.
Mostly, Dean values his family and their safety. He has killed a demon and its human host in order to save Sam's life, and he's sold his own soul to save Sam's life.
Castiel: It's very complex. If the pizza man truly loves this babysitter, why does he keep slapping her rear? Perhaps she has done something wrong.
Dean: Are you watching porn? Why?
Castiel: It was there.
Dean: You don't watch porn in a room full of dudes. And you don't talk about it. Just turn it off. Well now he's got a boner.
I don't trust him. Dude's hiding something. I can feel it and if you weren't Robo-Sam, you'd feel it too.Dean
