"Well, good, thank you for the invite..." it's just dripping with sarcasm because, of course, House had taken it upon himself to come in even before Chase offered. It's awkward with Chase acting the way that he is, he won't deny that, but he doesn't think it has anything to do with the last time they danced and what had come after it. Unless, after, he'd changed his mind about what had happened, which he doesn't think he did, it was something else, and that was slowly grating on his nerves, now that he had to face it one on one. It's clear that Chase wants him here, he's just got something on his mind that he's not dealing with well at all.

House is moving to walk past Chase and reaches out to swat him on the ass as he comes to a stop beside him. If it wasn't for the music that played on, the slap would be a hell of a lot louder in the small room.

"...quit being a brat. It doesn't suit you."

Except that it does, actually, suit him very well. House has this overwhelming urge to just spank this sullenness right out of him...
