"No. When you're better, I'm gonna kick your ass. And Dean's. I'll show you assholes Fight Club, hell yeah." He puts his hands on his hips and nods, tapping one foot while he makes his best tough guy face... which somehow involves him biting his lip. It's not a face he practices often.

He watches Derek get settled and sighs, looking up at the ceiling, then down at a random spot on the floor while he considers his options. Leaving Derek here by himself seems irresponsible, and Derek probably wouldn't mind having his pack around. And he's practically naked. Not that that matters. Or is relevant to this train of thought--

"Do you want me to stay?" Hell.
