"Well, I mean." Derek's tone has changed and it throws him. "I'm not gonna go back to my place. You could collapse because your stupid ass wants water or something and then you'll hit your head and get concussed and who's gonna be here? No one."

He says it like that in and of itself is enough reason to stay - concussion prevention - and then sits down on the bed with as much finality as one can while bouncing on a mattress. "Of course I'm gonna stay." He lies down and grabs one of Derek's pillows to punch and fluff, resting on his stomach with one arm under the pillow and reaching over with the other to pat at Derek's chest.

After a couple of pats, he just rests his hand there. Pack contact, yadda ya. If it helps, right? And Derek's warm, and right there, and... yeah. He shakes his head a little to clear it, voice feeling too loud now that they're both settled. "Do you need anything?"
