Leander isn't an enclaver, and at first glance he doesn't see his brother and asking around if anyone knows where Gaheriet might be isn't helping so probably Gaheriet is dead, which he will have feelings about at a different time that is not right now, and the point is that he doesn't know anyone here.
So what's his next move now.
Well, when he puts it that way, his next move is obvious. Start meeting people. He can try to be impressive, which isn't quite doomed-- he's good at languages and he's good at what he does, it's not his skills that are going to be the problem-- but according to Astor (the only one of his siblings who's made it, probably the only one of his siblings who will, hey remember how he wasn't going to have feelings about that right now) freshman year isn't for making specific alliances it's for setting general expectations.
So what he's doing is going around, helping get water to people who seem like they need water, smiling at the kids who are clearly freaked out, introducing himself, mentioning his specialty and his many, many languages to people who ask.
And so, "Hi," he says to a girl who's wandering around, "I'm Leander, I think our rooms are near each other?"
