I'm not sure if/how he and Aran might run into each other, but maybe there's something? He's not really a massage guy?
He's certainly a drinking person though (maybe a bit too much) and he doesn't need much of an excuse to go to a bar and meet people there.
With Desi... well, Adam doesn't have anything to do with any sort of underground that isn't a railroad. The same probably goes for the sort of places where you might encounter successful upper-class entrepreneurs. But if he ever did he'd definitely semi-grudgingly appreciate the eye candy. Because hot damn.
If Marek is on the same university that everyone else is at they might run into each other there? Adam is researcher/sometimes assistant professor there.
And oh geez if he ran into Norah. He's the product of one of those types of master/slave relationships and it did NOT go well in the end. She'd probably remind him of a younger version of his mom and bring on all the feels.
