I don't think most of them have met, but for the ones I can remember...

Cid hasn't really had enough time to get to know Lara, yet. So she's been mentally designated as 'that chick who followed Vincent'. He... might end up liking her? idk, it depends.

Saïx... is honestly thinking about other things more than NiGHTS right now. But if s/he gives him a good fight this may change.

Reno, well, he finds Knuckles interesting and I should have him poke Knuckles more, orz. Not sure if there's anything past that yet. LOL, Turk has issues.

Aaaaaaand I think that's everyone who's met?
