Well, at least he's used to spending a lot of time with other people who are endlessly curious about things. For once, he's found one who's apparently on the magical end of the spectrum, and maybe that's a good thing. A different type of opinion, different experiences. But it sure is even more alien to him than anything Will says about physics, or Law says about medicine.

"I used to have to think about it more, when I had less experience," he says, starting with the simplest of the questions first. "Now it depends on what I need to do. Usually it's no harder than thinking about the diameter of the barrier I want, or focusing for a second on what I'm trying to mute, if it's not myself. That's the easiest, just making me the only target. ... Never thought it really felt like anything, though. It's the sounds that stop." Which maybe means it's an external thing, but he's not exactly sure if that's the right answer to that particular question.

Also in around half a day he'll learn newer answers to these things when messing with water, but until then, Gregor will have to make do with whatever he gets here and now.

But before Gregor can ask more questions, he's curious too. "What about you and your magic? What does that feel like?"
