"I look forward to it," he says earnestly.

Grin.

"Okay now I wanna learn sorcery!"

He grins back.

"Of course! Now, you've begun to observe the patterns of the world, but can you alter them? Don't, for the moment," he cautions, "but--examine them more closely, see how you could move them."

"Okay..." She tries that, whatever it means.

If she comes at it the right way, the patterns do feel like something she could affect if she tried.

"Okay yeah I totally see it."

He smiles. "Most things you could possibly do to the patterns would be...not things we especially want to have happen." He takes a book off a stack and leafs through it, then hands it, open, to her. 

There's some kind of diagram on it, that looks a lot like the way sorcery "looks" through sorcerer-senses.

Oooooh this book is cool. She nods along his explanation.

"This is a fairly simple spell, and when it goes wrong it generally does so harmlessly. Try rearranging the patterns in front of you to match it."

"Okay."

Can she do it? How hard is it?

It's kind of tricky, but if she focuses and takes it slowly she can probably do it.

She can be patient.

Then, eventually, the patterns match up and a small red ball of light appears in the air.

Eeeeee this is so cool and not at all like her magic eeeeeeeeeeee!

(Can she figure out why this pattern causes this as opposed to something else by looking?)

If she tries she might lose her hold on the pattern.

...oops.

It dissolves pretty quickly back into static.

"This is fun," she declares. "Why did that specific pattern generate a red light?"

"In terms of what part of the pattern do what, or in terms of why I chose a pattern that generates a red light for your first try?" he clarifies.

"Why not both."

"Red light, because the easiest ways to err would either have resulted in nothing, or light a bit higher or lower energy," he explains. "Starting with red, there's more leeway before you risk running into ultraviolet or worse." And then he explains some of the bits of pattern and what they mean.

Ooh so this part she can change to get other colours and—what if she did this, would she be able to get multiple colours? Multiple lights? And there's this other part...

Yes but it is very important that she check with him before actually performing any of these alterations until she has a good enough track record of getting things right that they can be confident it won't explode in their faces.

Absolutely, no recklessness with explosives.

Well, "explode" was mostly metaphorical, there's all kinds of ways this kind of thing can go wrong, but her caution is appreciated.
