I've got a feeling he's probably a regular at The Merry Men. He loves a good not-quite-dive bar.
Adam's not much of a club guy usually, but he gets desperate every now and then. It might be funny if he ever did run into Desi there and did try to properly drool or flirt. He's well-aware that he's objectively pretty terrible at flirting in a typically Acquiescent way and he generally has... mixed success.
And yeah. He's usually holed up in a library or archive so not much contact with the music department.
If he ran into Norah though he probably wouldn't be quite so overt. Since he was born a Helot he's pretty darn good and judging how to act around them individually versus as a monolithic group. Plus it's not quite safe to talk about that. So if he did meet her he'd just try to have a normal conversation. Albeit a kind of sad one from his end.
