[Undine was aware that there were still new people showing up on the ship, but she still somehow was surprised to see an unfamiliar teenager in the library. Look, look, there's a lot of adults puttering around and doing adult things, but not so many people her age to make friends with (even though she's conflicted for being happy to see someone new, because, like...this place sucks, and no one should be here).

Right. Anyway, she doesn't want to startle Alex, so she hums as she approaches, heading to a nearby shelf instead of immediately accosting and probably scaring the new girl. It seems more polite that way.]
