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."

"That's certainly a benefit...it's not how I would arrange things but as long as it's assigned nigh-randomly the age limit is probably for the best."
"Plus as long as it's arranged randomly at least there's a defined point at which you stop planning your life around the possibility. I don't know, maybe I'm just rationalizing because I don't know how to change it. I wonder if you can diagnose incipient magical girls, do you want to strafe an elementary school sometime and find out?"
"Oh, that would be marvelous--it would mean Jaromira won't, more's the pity, but that wasn't especially high-likelihood anyway."
"They're probably not in session right now but if you want to be a few minutes late to the club you can maybe catch some buses leaving, enough to get a guess. I can show you where Renée teaches."
"I look forward to hearing your results. Lemme show you the school." She takes off and makes a beeline for her mother's workplace.
