jamie doesn't even know trevor's his soulmate, he just thinks the coworkers he pissed off by not filing paperwork properly the last millennia or so have finally gotten their revenge by having him psychosexually tortured this assignment because trevor's so beautiful and charming and jamie can't help but to fall for him, so he's inventing all new levels to the concept of religious guilt
he's also getting actually tortured because he hates hockey and hates that he has to actively play and play well (he did get some handwavey heavenly help for his skill level but he still has to put in a lot of hard work on his own, which just absolutely blows)
so between all the pent-up umm... emotions trevor's evoking in him and the absolute loathing he has for skating, the one highlight of jamie's season is finding out fighting's not very penalized in the nhl, so he becomes a total enforcer
obviously it is part of his job description to protect trevor (who gets a special kick out of picking fights he can't finish) but it's also a great way to vent his own frustrations at everything in general, so jamie figures out how to have some fun
trevor thinks it's really hot and gets even more reckless when he's trying to rile jamie up
some nights after team celebrations, jamie loses his patience at trevor hitting on anybody within a 30-foot radius and throws him over a shoulder and carts him out the bar
trevor's texting all his buddies like "omg did you guys see my new teammate? dunno where estonia's been hiding this kid but i'm sooo happy we signed him" (the backstory HR invented for jamie was quite slapdash. sue them they're overworked)
meanwhile jamie discovers the offseason exists and thinks he's going to get a nice vacation: maybe that's true for the hockey-playing part of his job description, but then he finds out trevor's heading out to the hughes lake house, which might as well be a den of sin in jamie's eyes, and realizes the grind never stops
at some point trevor finally snaps from jamie's not-subtle-in-the-slightest cockblocking and is like "jameson you're going to deflower me TONIGHT or i'm jumping your bones right here on the couch in front of everybody"
anyway jamie has a mouthful of trevor's hair the next morning when his termination notice flutters down from nowhere and tapes itself to his forehead
"Termination Due to Reconnection with Primary Karmatic Bond and Resulting Unavailability for Future Guardianship Assignments"
and that's how jamie finds out him and trevor are soulmates
trevor's half asleep like "what's that" and jamie's like "don't even worry about it"
jamie, 3 seconds later: wait does this mean i'm stuck as a fucking hockey player for life now
jamie learns about WAGs and tells management he's quitting by pointing and going yes i'm that now
or alternatively, he fakes an injury:
j: yes my left shoulder has given out for good woe is me i can't shoot pucks anymore how unfortunate
t: it's your other left, babe
j: yes my other left shoulder. so unfortunate
