i'd love her for anything tbh, but i initially thought of her for his dealer that he's strangely protective of and friendly with. the older woman line is a bit more complicated and would kind of depend on what you had in mind for her, but i initially thought it would be something like a very hedonistic one night stand that came back around to them in a very real world way where they had to deal with each other again after kind of slinking off into the shadows to (unsuccessfully) never be heard from again. bonus points if she's married/engaged and there's some guilt about that aspect of it because i'm a sucker for complications, but that's not necessary.
