Updated Polycule dynamics because I don't think I was very clear in my last post on the topic:
N, V, and Uzi are all dating.
Thad is in a QPR with N, V, and Uzi— where he's closest to Uzi and least close with V.
They're all friends, and while Thad doesn't actually live with them (he has his own place) and they all have their own separate rooms, they'll all mostly end up in one of their beds to sleep anyway.
They'll hang out, talk, and do basically everything they can together.
When it comes to being intimate, Thad's the least likely to do anything, oftentimes just sitting to the side and making jokes instead.
