The enclavers tend to cluster. A lot of other kids have somehow, probably not even with mind-control, made friends on the first day and are sitting with those.
And some kids haven't, and they end up sitting at the more dangerous tables, near the vents and near the grates and far from the food.
Nothing wrong with that.
Hannah should, strictly speaking, not be anywhere near this dangerous chunk of the cafeteria, but it's the first day and she doesn't give a shit about the rest of her enclave and she wants to get in a little trouble, as a treat. She hides her power sharer in a pocket and goes looking for interesting people.
Miguel understands how cafeterias work and this is a table for social outcasts, which is bad, but less bad than standing there eating, and probably he's not allowed to leave with his tray full of food? No one else is doing it, anyway.
He sits down and tries to look relaxed about this. He is not relaxed about this.
Looks like a good table for meeting people. Might not be good for his life expectancy but, hey, he's here for a good time, not a long time. And it looks like nobody is talking so he's going to have to be the one to do that.
"Hey everyone! What're your affinities, I write songs."
"Oh! Oh, speed, my brother knew someone whose affinity was speed--they might actually still be here, come to think of it. Not that he would be caught dead around this table. Ribo, small things, I assume you're both going artificing track? ...I forgot to introduce myself, didn't I. My name's Wil, I'm not used to so many new people. Good sort of unused, though."
....Honestly, Wil's still caught up on the focus potion. Or adderall, honestly, he'll take either. He should probably wait before letting on his interest there, though.
"I have some spells, what languages does everyone have? I've got English, German, Latin, Dutch, Spanish, and Ancient Greek pretty well, plus enough French, Mandarin, Russian, and Japanese to not get fucked over by them."
