"It works so far, anyway," Draco adds, feeling his own sort of mix of relief and reassurance, if not genuine amusement, that he just happens to be dancing with another wizard. If there are others in this place Draco hasn't found any yet, just Billy. He may know nothing about him otherwise, but at least he's not the only one.

"There's still a huge list of spells I'd like to test, but it's been a bit of mad day..." he trails off for a moment, before nodding his head in the general direction of the bar with a bit of a lazy smirk. "D'you want to get that drink now? I don't think the music's going anywhere."

Which, Draco considers, is more of a curse than a blessing, really. Their unoccupied corner of the bar has been relatively peaceful, but they will need to wade through the chaos to get to the drinks on the other side.
