Hmm the NYC connection would be tricky, but maybe? Luke was a VERY different person when he lived in NYC. So he would have been there from 2001 to 2007, and worked on wall street in investment banking. He was often in one-night stands, or weeklong relationships, if you could call them that. :X So I don't know if that would work for you, but happy to explore.
Once he relocated to SF, he's become a lot more sane. He does go to therapy - so maybe they even crossed paths there? I never specified who his therapist was. And he lives in the mission and works in Tartine, if you want them to cross paths there. :X
once we sort out NYC or not-NYC, we should just throw them together in a scene and how they work?
