In this soup kitchen sits a nun in partial habit, sipping water and frowning at a desk. It is very irregular for adults who aren't volunteering to be at the soup kitchen. It is very irregular for expensive electronics to be in the soup kitchen. The volunteers do seem to know her; they call her "Carlotta".
I take as my charge this country and its people, and I swear none shall go hungry that my hand can feed, and none shall be killed that my hand can protect. With this oath I become a thane of Thule, servant to its ruler and friend to its people. May I never forget my duty.
"What should it feel like?" says Oat.
"It should feel like... like it's exactly the right thing," he says. "The translation says what the words mean, but it doesn't really say what the oath means, and what the oath means is definitely about helping people with more than just avoiding starvation and murder."
"Avoiding starvation and murder are good things, generally," says Oat.
"... Yes," says Sindri. "But they're not the only good things ever."
Once they have had time to pick bunks and get acquainted with the room their "mom" has them all get in uniform. (Bella asks if she's supposed to change somewhere else. Crane tells her to get over it. That wasn't what she meant, but she shrugs and changes with everybody else.) Oat's uniform is obviously cut down from a larger one. They get to eat, which everyone is delighted to do because they didn't do so before their launch. And now they are all supposed to troop to the gym, which they will have to be in on a daily basis to compensate for the low gee. They are not to be out of uniform at any time they're not in the shower, at which time they should either be actively in the water or wearing a towel. The gym is nice and cold so this shouldn't present a problem. Look at all this nice gym equipment, go exercise.
The handholds on the walls are spread out such that most children can grab two at once without a lot of trouble, although the littler kids have to stretch. Sindri can manage it with some pairs of handholds but not others; Oat has no hope. Oat, therefore, spends his time on learning how to accurately propel himself from one handhold to the next, and Sindri copies his tricks, finding them more useful to him than the official maneuvers designed for people less tiny.
