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."

"Perhaps I'll prepare two. A default and a contingency in case she turns out to be egregiously irritating and merits a sharper tongue."
"What presentation topic does she get if she irritates you? Or do you just mean you'll talk about it differently?"
"If she irritates me she gets a presentation on the relative merits of her preferred system and circle critiques."
"I'm not sure that counts as a presentation about magical girls and magic."
