Well, yeah, kids that age have a lot of energy. Expecting a single adult to keep up with one all the time is kind of ridiculous. But for a few days, she can manage it pretty well.

Back up to the roof to eat?

He wants to sit on the edge of a fountain instead.

If he's been paying enough attention to notice how her ears move when she's stressed, he might catch that she's not thrilled about this. But she follows along without complaining.

He has noticed the ear movement but has not connected it to stress and there are not too many people now that it's evening and anyway fountains are lovely running water is so pretty! Do kobolds not like it?

The fountain is nice! And that has to be magic, doesn't it, maybe she can work out how to make fountains with her magic sometime.

He doesn't think it is, actually, but maybe? Lots of things in the city are magic.

...Huh. How would you even do that, without magic? Anyway here's how she'd do it with magic...

She closes her eyes for several seconds and then dips a finger in the fountain. Water begins appearing from a spot a few feet up in thin air, and falling immediately back down into the pool.

Ooooh!!! Is she teleporting the water! That's brilliant! 

She's absolutely teleporting the water! Making it go up like this one does, or in other directions besides 'down', would be tricky but she could probably manage it somehow, and then she could make very elaborate fountains if she wanted to. That might be a fun way to spend an afternoon sometime once she's had more time to think about the best way to go about it, just teleporting water all over the place to play with.

He loves this idea and is renewedly sad he can't learn magic.

Aww.

Once I've worked out what I need to do to make water go in directions, you can help me design a fountain? Or design your own, if you want, and I'll cast the spells for you? The design is the important part anyway, really.

Yeah but I want to be able to do the magic too. When I'm bigger, maybe? 

We could have a fountain that danced water all around a room!

When you're bigger, and more used to being careful with things, yeah, she grins and hugs him. And we can definitely have a fountain that dances water around a room in the meantime.

He enthusiastically starts describing how he'd do one. 

And she smiles and listens and points out when he wants something her magic definitely can't do, and occasionally stops him to run bits of fountain water through various teleportation sequences to make sure they're possible, and generally lets the project be his project.

And he is so happy! And the fountain is so intricate!! And he doesn't react badly to hearing something won't work, he's generally pretty good at thinking up another way to do it, and the Mingling comes and he practically forgets to look.

Gosh that's bright. The kobold squints and shields her eyes.

Do you not like it?

It's very bright. It's very bright here usually, too, but if it gets much brighter than this I probably shouldn't look at it at all.

I think this is about the brightest. Dunno. I don't get to come outside much.

Hug.

I'm not in a hurry. I can sit here with my eyes closed and watch it with my magic if nothing else.

We should go in anyway, my father might be back and he'll be upset if I'm out.

All right, she sends, and pops them back to his room.

Where it transpires, a little while later, that the King is back and was upset Fëanáro went out and Fëanáro is summoned to apologize and be hugged.

...unless it seems like a very bad idea, or Fëanáro wants her not to, the kobold will tag along.
