No recklessness with things that explode or may cause other unspecified terrible things to happen, then.

Excellent.

Several of her variations are confirmed safe and she is allowed to try them.

Eeeeeee this is way fun and she can just do it without worrying about mana. That is so great.

And her variations go off without a hitch!

Eeeee! And she has thought of some more but perhaps Horace has a curriculum in mind rather than indulging her fancies?

They have time for fancy-indulging! There is a curriculum but it doesn't, like, have a time limit or anything.

Eventually she'll want to learn new things that other people have come up with rather than trying to rederive all of sorcery from scratch, though.

She can do that. Here is a slightly more complicated spell to try.

Eeeee!

He will teach her several spells before her lesson is over, and he reminds her not to do any sorcery yet not supervised by a more experienced sorcerer.

She promises not to but this is so cool she likes this when will they do this again?

Day after tomorrow?

Sure!

In the meantime does she want to go out for a celebratory dinner or something?

Yes!!! But first she promised Horace she'd show him what magic looked like to her and why she thought sorcery and artefacts and magical girlness are the same thing.

Oh sure.

Horace is fascinated.

And it's pretty obvious that they're the same thing, right? Kaede bounces a memory of the artefact too, to help.

It is definitely the same thing on, like, at least one relevant level, but there are alternate hypotheses consistent with the data.

Oh?

Well, the three are obviously correlated relative to Kaede's world's magic, but correlation doesn't necessarily imply causality--sorcery causing artifacts is a much tidier theory than an artifact spawning sorcery, for example, but both are possible. Or some other thing no one knows about right now caused all three.

Oh yeah, sure. They look like the same basic kind of—thing—and the simplest hypothesis is that the more versatile of the three made the other two, but other configurations are reasonable interpretations, too. They're definitely not, like, completely separate.

Compared to her native magic definitely not.

Mmhm. Well, they'll see each other in two days! Now she has a celebratory​ dinner to attend.

"In the mood for anything in particular?"
