One aspect I wished both twst and the fandom explored more are the consequences of Jack’s actions in book 2, because what he did is basically social suicide.
Guy went against a plan everyone in his dorm, including Leona who he used to idealise, had been on. This plan, as bad as it was, was for a lot of Savanaclaw students their nearly only hope to get scouted and make it as pro. That is ground to give birth to a lot of resentment, and Savanaclaw was shown to be quite the brash dorm, I don’t think they would forgive Jack that easily.
And like… Jack already had issues in Savanaclaw beforehand, seeing how he was targeted by a group of nearly 30 students who wanted to beat him down if he didn’t stop playing for the dorm, and only got away thanks to Leona’s intervention (see Leona’s dorm card vignette, which happens before book 2). And now with Jack being the reason their plan failed, the reason why they lost to Diasomnia again and couldn’t be scouted? Yeah, they are not going to kindly stay put, even if Leona and Ruggie try to step down. To them, Jack is a self-righteous snitch and traitor, and wouldn’t those kind of people deserve the consequences of their actions?
And it’s not like Jack would have it much better outside his dorm, because how many students are aware of how exactly Leona’s plan failed? There was only the Heartslabyul gang and the Diasomnia family in the confidence, so for most of the other students, all of Savanaclaw’s students must have been in it, including Jack. Heck, considering that Jack was in the Spelldrive team and the whole plan was about it, it would make more sense for most students that he was an accomplice.
And sure Jack would still have friends with Yuu, Grim, Ace, Deuce and Epel (and much later Ortho and Sebek). But is it enough when everyone else are against you? When not only your school environment but also the place you live in full of people who resent you and who would be showing it very clearly? When you are the target of endless cruel words and angry violence, because you dared going against an unfair plan that injured people?
The only times I hear all of it being mentioned is usually in first years centric fics, but it’s usually just that. A mention by Jack during some conversation that he isn’t too comfortable at his dorm, but nothing more. No going deeper, no exploring what could be happening to him. And I don’t know, I think it would be an interesting aspect of both his and other characters to explore.
