Well, Radar guesses that's one way to forget about the noise of the party: get his heart beating so loud and his head screaming so much that he can't hear anything else. Oh, he really hopes nobody else can see how bad he's screwing this up.

Seconds slide by. And... Dahlia keeps holding his hand. Doesn't stop smiling at him like he hasn't screwed up anything at all. Has he even blinked in the last thirty seconds? Maybe he should do that. Maybe... maybe he should try to stop panicking a little and just -- hold her hand back. Yeah.

...Maybe he could slouch down a little and put his head on her shoulder? It's spinning an awful lot; it might be a good idea to do that anyway. So, very, very carefully: he does.
