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." Katarzyna doesn't mind it, though; the school library is excellent, and basic manners and care for the books has endeared her to the librarian to a sufficient degree to lubricate the interlibrary loans process when there's something she wants to read that they don't have.
"You're welcome!"
She wanders off to find Isabella.
"Sorry for abandoning you for your brother but I think I really helped his understanding of math!"
"...I don't know that I would have found him intrinsically interesting if I met him first but I think he qualifies as being transitively interesting on account of being your twin."
"It's not that he would have to be a certain amount of boring, it's that I hadn't previously realized that the bar existed. I don't find my sister's friends particularly interesting, but then, she mostly has casual friends, not close ones."
"I really hope I can synergize powers and I just haven't met two that synergize well at the same time."
"Yeah. Maybe visit a really big hospital that might have two magicals on staff at once."
"They'll probably both be healers, which seems likely to either be excellent or redundant for synergy purposes."
"I looked into it, because I might be able to stop the progress of a problem even if I couldn't heal it, give more time for healers and doctors to do stuff, but you have to carry insurance and have parental permission if you're young and if you have a weird power you have to test it under controlled conditions at a research hospital, and it might be worth it but it's not just a matter of walking in."
"Mm. Yes, that's the kind of thing that would definitely need to wait until I know more about my power. I can at least ask any volunteers that are there if they can help me with that, though, you're quite right."
