After that first deeply bizarre conversation, Leander goes back to hovering.
(He still can't find any news of Gaheriet. Nobody has heard from him. Nobody seems to even know what killed him, if something did. This is a terrible thing to dwell on and he told himself he wasn't going to do it but whenever he tries to leave it alone it picks at him.)
Most of the people who needed water have it, by now, so there goes his usual strategy for distracting himself which is picking a task that needs to be done and doing it until he stops having any feelings at all. But he can put on a face like nothing's bothering him and go around the room saying hi and introducing himself, being friendly and polite and competent-enough and keeping an eye out for anyone who stands out in a way that doesn't scream 'run for the hills'.
Which is how he ends up approaching a girl who is.... chanting a warding spell, it sounds like? At the maps?
