Cam catches a summons while he's in the middle of Atriama. He's seen it before, it's fine.
"You're a very good person and I love you. - Do housefolk like to be pet? I have always wondered."
"So is Princess going to learn Latin with your accent? Not that I mind if she does, it's a neat accent, I like it."
(The Britannian accent resembles a British one in a sprinkling of sounds but is otherwise not very like any Cam's familiar with.)
Jackie's knees now have a slightly murderous glare directed at them. "Right, because this is going to end with her physically able to produce human speech," she says, lightly, despite her expression.
"That program will actually train her on an accent common to people who live on the moon where I'm from because it was judged the easiest to distinguish minimal pairs."
"Our moon, like our planet, is a sphere of rock. It doesn't have air, so people live under domes."
"Right, and - gravity points to the middle, apparently, so you don't have to worry about falling off? What got rid of the air around a whole celestial body?"
"Not having air is default, the air on Earth was generated locally and kept in place by gravity, which as you have surmised points to the middle of the sphere."
"We've got air here pretty much everywhere there isn't something else. What does your world have instead?"
"If you lower the pressure enough, there's nothing there. That's what's most places is nothingness."
"Oh, just vacuum everywhere? How thrillingly abhorrent - we have a little piece of vacuum in a tchotchke, Jackie, where's the tchotchke - "
"I guess we might not have a little piece of vacuum in a tchotchke, then."
"Alas, that's one of the things I can't make, since it isn't a thing."
"We shall have to acquire our empty symbols of rebellion against the natural order elsewhere. Or go without them."
"...okay. Uh, anyway, I'm mostly just here to check in with Princess and see how her hardware's working out but if you guys need anything other than vacuum I can help you with that before I go build myself a cabin in the woods."
"Sure. I can't make satellites under the circumstances but I'm not going too far for grounded repeaters." He gives her a phonelike object.
