She is sitting in the library, studying. It's her most common pastime, by hours; spending time with her sister is more enjoyable but Jaromira prefers to socialize more broadly and Katarzyna would only get in the way. This is better on net; the two of them share a room, so it isn't as though her sister's time is entirely hogged by the other girls who call this boarding school "home." Or at least "prison."

"Synergize them--connect their magics to work together like I would be doing with the copies?"
"I still don't think I'm following the distinction you're drawing between that and synergizing copies."
"Oh, yeah, I guess that makes sense. We could fly out to the desert and get a rock?"
"Off we go then. I'm going to be ravenous at dinnertime." She takes a flying leap and leads the way out to some suitably empty space with rocks in it. She picks up a rock and holds it in the air, waiting for the go-ahead.
It - slows down. It doesn't stop.
"That didn't completely not work, so it's not a hard limit. You definitely need a style pro."
"Definitely. I plan to look into it as thoroughly as I can make use of as soon as nothing more urgent is at hand."
"Well, you see, I have a date with a very pretty, intelligent, and thoughtful girl."
