Trust (And How The First-Years Have It And Don't)
Ace puts his back to Deuce when talking to Cater and Trey, and it's a simple thing that they almost don't notice, but they realize that he hasn't turned his back to them since they stood by and did nothing when Riddle ordered them to be thrown out before his Overblot.
Deuce puts his back to Jack when he approached Riddle asking for help with his homework and Riddle realized that Jack is watching out to make sure that Riddle doesn't collar Deuce without good reason again.
Jack puts his back to Epel when he approaches Leona and Ruggie for permission to go to a first-year sleepover and the two of them realize that that Epel's making sure that they don't do anything like they talked about when Jack overheard them talking about their plan.
Epel puts his back to Ortho when he goes up to Vil and tells him- not asking, telling him- that he's joining the sleepover and Vil realizes that both of their eyes are watching, both for Rook and for any more poisonous gas.
Ortho puts his back to Sebek when talking to Idia through his door and Idia, watching through the security cameras, realizes that Sebek is making sure that they won't be attacked from behind or jumped by any technology.
Sebek puts his back to Yuu when he approaches Lilia and Malleus for permission to join the sleepover and the two of them realize that the both of them are grounding each other and ensuring that they're actually awake.
Yuu puts their back to Ace whenever they speak to any of their upperclassmen, trusting that Ace and the other freshmen won't hurt them like the others, won't leave scars on their skin and mind, won't leave red and black hanging in their vision.
Somewhere along the way, the upperclassmen realize that their first-years have learned both how to trust and not trust anymore. And they don't trust in obvious ways, in not letting someone into their blind spots, in not taking anything they hand them, in not meeting their eyes or speaking what they really think.
But they've also learned how to trust in quiet ways, in the little things. In the way they smile true smiles at each other, in the way that they grab each other's hands without hesitation, in the way that each boundary is pushed to where it's safe before being gently released, nothing dangerous having been touched.
And their first-years have always been loud, but the distrust and the way that the upperclassmen never see their backs speaks volumes without a single word.
