Derek lifts his eyebrows at her suggestion that they change tack and check out R&D. He knows already that's where the explosion was before Buffy even says it and while his interest is absolutely piqued, Derek shakes his head. "Are you crazy? That place is probably swarming, they're bound to be investigating, don't you think?" he asks. Maybe they wouldn't be investigating this late into the night but one never knows and Derek is on the wrong side of paranoid right now. Of course he assumes the worst.

He gives a little huff of amusement. "Sorry," he replies, realizing that he hadn't meant for it to be at her expense, really, but it is true. He does feel a little better.

The more she talks, the less Derek really knows how to respond. This isn't the sort of conversation he's accustomed to having with anyone, let alone a female. "Well...it could be worse. He could've been someone you wouldn't have banged, right?" he asks as the elevator doors open. Derek takes a few steps forward and holds the door open with one hand while crouching slightly so that she can climb up onto his back again. "That really sucks though. Do you think there was like something in the water today or what?"
