"Most people put things in their kiertens at least temporarily sometimes," she points out. "It's just that the palace is so big I guess they never have anything that doesn't have somewhere else to go."
If it were strictly up to him, he would rather show off the wealth of the royal family with lots of decorative crap - beautiful gardens, nice clothes, pretty statues, books, paintings - than with a big empty room that could probably fit four other entire houses in it if they were little enough.
But it is not, in fact, up to him.
"Well, it'll probably be up to you one day," Kiri points out. "Kings can get away with doing unusual things like filling up kiertens. Unless it's your little brother. What's he like, does he have a personality yet?"
"Well, now you all add up to five, the king and two queens and two princes."
Kiri giggles. "I think the numbers are silly too. Or - well, I don't think they bring luck, anyway, but they're sort of tidy. But people do a lot of things to get good numbers that they wouldn't do just to be tidy."
Kiri giggles again. "I don't know what I expected a prince to be like but you aren't it."
Kiri laughs. "Your costume has a rip in it," she points out.
He stops walking and looks down at himself and twists to try to see the back of his pants and turns a full circle one way, and then another full circle the other way with the opposite twist, and then untwists and inspects the torn hem. Which he sort of knew where to find all along, but the elaborate search was more fun than merely remembering.
"Yeah, I'm fine. I fall over all the time." Kiri gets up again.
Kiri admires them, but doesn't see a need to stop either.
Kitchen!
The prince pokes his head in and announces, "Cook's not here! Wanna see the gardens next, or the dining rooms, or what?"
(The two named options lie along equally convenient paths for seeing all the interesting parts of the palace without doubling back or looping. Anything else, and he'd have to figure something out.)
"I'm glad I don't set things on fire by accident anymore," Kiri remarks, running her hand over some leaves.
"I light the hearth that way sometimes. I've been trying to see if I can cook eggs in their shells, now that I'm pretty sure it won't get out of control. But most things around me don't need to be on fire."
Kiri stops in her tracks, (stumbles, catches herself, and) frowns.
