I have zero dogs in the Jury romance fight--I see where people are coming from but I never played his romance, he just as a character is deeply, deeply uninteresting to me, but I feel like blaming Lyra's character for Jury's decisions is not great? It's been a bit since I played through it, but isn't there implication that he's kind of with her to advance his career, get more attention to the current American Protectorate, get more opportunities to get back in the public light? It seems like Jury's actions aren't Lyra's fault--she doesn't have any relationship to the MC, it isn't really any moral failing on her part that Jury came on to her.
I dunno, I mean again I didn't romance him so I don't know how it goes, but I just got the impression he's kind of an ass and cares more about attention than much else, and that continues into the next book. If anybody wants to disagree with me, please do, but it seemed like about where his character would go.
Of course, not saying that the people who romanced him deserved that at all, I absolutely get being upset by that. But I didn't feel like Jury had much of a character arc in the original trilogy, he's just sort of belligerent for the sake of belligerency to the MC throughout it and then kind of turns on a dime towards the end of the third book. I wasn't convinced he'd learned his lesson at all, so much as just changed away from what looked to be the losing side. It seems like if Zach wants to give him any kind of satisfying character progression, he needs a lot more content, and separating him away from the MC you aren't in control of anymore was probably necessary for that in order to not just feel like he's writing your MC for you in the new season. The other love interests pretty much have their developments over the course of the trilogy, but since Jury is sort of an antagonist throughout, he doesn't get any of that, he just gets that quick wrap up "now we're happy and he's a good guy despite being very markedly not that the rest of the time" and while it's definitely shitty to the people who romanced him and wanted the same happy ending the Jenny, Lucky, and BM romancers got, I can't really argue with what's apparently a move to let the poor boy grow as a person. Like, at all.
