that's perfect, they'd definitely know each other then! depending on how protective he is of sky they could have maybe not started off super warm on each other? especially being that jae is a few years younger than her and was freshly 21 when they got together not his wisest years for sure and it looks like theo is 6 years older than jae himself so there could potentially be a rift there. even if theo was chill about them, jae probably would have been intimidated by him in any case but genuinely would respect him and be really fascinated with his past SO whichever way things have gone in the last couple years, he'd probably still try to have a friendly connection to theo since he and sky are still on good terms post-split
