It politely quiets down to where it initially plateaued shortly after it's caught his attention.  This is a fair tack above where it was a moment ago; it must have faded out during the conversation.  And there's another emotional note, added subtly to the cheerfulness - quiet confusion, or encouragement, with maybe a hint of condescension - this is magic, and it's meant to be used; he knows that, right?  He does know that it's for him to use to make his life better?  It can be meant to be saved, but eventually - in a week or two - it'll run out, and it would be sad if he didn't get any life-bettering out of it before then.  No pressure, it's just checking.  But.  Does he know that.

"- now it's not as yelly but it's - pushy."

"Weird," she repeats.  "Uh, I never had it do anything like that - I don't know whether to expect that this is a weird interaction or if it's just what happens if you don't use it right away the first time - ish; obviously you spent the sliver - I don't think responding to pushiness by doing the thing you're being pushed into is generally the best decision but I also don't think the magic is smart enough that incentives matter literally at all?"

"I want to - get used to it so that I can carry a reserve around at all instead of planning to spend it all down immediately every time - so I guess I'll sit on it and track patterns." He starts a notes file.

"That makes sense."

The magic's talkativity stays level until he tries to use it or starts thinking about something else.

He does eventually start thinking about something else!

It gets out of his way again, fading to almost nothing, until he even vaguely thinks about it.  At which point it does another sforzando.

"- okay, it gets off my back if I am not thinking about it but it comes back with a vengeance when my mind is on it again at all."

Judy looks up from her book.  "That's good at least?  The first part."

"Yeah, better than the alternative. Maybe with enough attentional capacity it'd be ignorable. Did you boost that? If you did that straight away that might explain why it's less conspicuous to you."

"No.  Just - mind control the first time, and everything else into teleportation.  - And one time I tested out the de-aging on my cat."

"Did it work?"

"There weren't like, crazy-obvious results from just doing it the once, but it seemed to, yeah."

"Cool. How does the teleportation work?"

"Well - "

It's so glad he asked!  He can teleport himself and things on or near him (as defined according to this criteria), and also people as long as he has pretty solid reason to believe this is in their best interests!  If he thinks about somewhere he wants to go that's within his current range, he can get a sort of proprioceptive map of where it is, complete with an intuitive sense of distance and how much magic it'd take!  (He doesn't get any new information from the map, such as if things have moved around since the last time he was there, but it locks his existing knowledge into a more concrete form!)  And it doesn't feel like it'd let him put himself through another object; it'd shunt him outside of it if he aimed for one!  Or aimed for a place he thought was empty but was wrong about!

". . . You good?"

"Clippy has me covered, apparently."

"Gotcha.  Makes sense."  She produces a sphere of lip balm from the pocket of her skinny jeans and thoughtfully applies it.  "It's still . . . very strange, being able to talk to anyone about this stuff."

"Very much The Masqurade at home?"

"Paper faces on parade," she agrees.  "And I didn't exactly like, chat about it with Sara either."

"Understandable. Is there magic theory you've been bursting to discuss or anything?"

"Not really.  Just, it probably would have been obvious that asking that would get you Clippy'd if I were - at all in the habit of imagining other people interacting with the magic, I guess.  - I like, blackmailed her into turning me.  Just so you know."

"It didn't sound like all roses but I don't recall blackmail specifically."
