And I'm not calling Sync creepy, I'm calling the writers creepy for thinking this story would work the way it's been presented.
The male writers do this a lot though. A few years ago, they had Colossus creepily stalking Kitty and the audience hated it. The sad thing is you can tell they want these moments to come off as the male partner romantically longing for the female (as opposed to vice versa) but the problem is the females could care less (Kitty) or is creeped out by him (Laura). (And yes, most of us would be creeped out by someone saying they had this powerful relationship with a "version" that may or may not still be alive) . It's almost what an "incel" would think is "romantic".
