They both start ushering him around like he isn't getting in their way, and Derek's shoulders relax the slightest bit when Patrick touches him. Shooting David a grateful smile, he follows Patrick up the stairs to their apartment. He's never been up here before, and the smell of it kind of rocks Derek on his heels.

It's the scent of the two of them all wrapped up together with happiness, sex, and family, and Derek just sort of lets it wash over him as he follows Patrick over toward the kitchen. It's peaceful like chamomile tea, even if they aren't his emotions to feel. Derek wants to tell them how good they smell together, how complimentary, but he knows how creepy that would sound to someone who doesn't experience scent the way he does so he keeps it to himself.

"Maybe just one," he says as he reaches out to accept the bottle from Patrick, smiling softly at his words. They're just good people, the both of them, and Derek is glad he came here tonight. "Shouldn't waste it on me, anyway. It doesn't have any affect on me."
