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.
Isabella does something. Now she is unsenseable.
"You have no sense of humor," says Alexis.
"I do have one, it's simply malformed."
To Isabella: "I can no longer sense you. What ability is that?"
"What does malformed mean?" Alexis whispers to Gabrielle.
"I can make things that are happening not happen, pretty much," says Isabella. "I mostly use it when I trip."
"Oh, that seems so useful! Could you use it on--a stroke, a hurricane, some more minor natural disaster-"
"I don't think I look good enough to do a natural disaster but I would probably be useful if somebody had a stroke," says Isabella.
"Well, that's what consultants are for, aren't they--I have no head for it whatever, my sister designed this outfit, I only chose the colors."
"My brother helps me. I do have dressier versions, but I've never actually encountered a natural disaster."
"I'm lucky enough that so far I haven't encountered anything I'm not willing to wear day-to-day but of course I would take uncomfortable and powerful over neither if I should in some way discover such."
"Anyway!" interrupts Mercedes. "Nobody ever made it to the Olympics through chitchat! Fliers in the air, pedestrians on the track, reconvene in thirty minutes for targets and style presentations."
Isabella shrugs and takes off.
So does Katarzyna.
It's a little hard to chat in the air. Isabella gets close to Katarzyna anyway and calls, "So what's your range on the sense?"
"I am currently uncertain! Fairly long on a local scale!"
"What does that mean in yards?"
"More than a thousand, less than ten thousand!"
"I was thinking you might have noticed when your car came in range of us!"
"I did, but there were enough turns that I'm not sure of the distance as the crow flies!"
"Did you note the intersection - no you know what, do you have a watch -"
"I don't have a watch--I did, but I carelessly got rid of it when I first starscaped and haven't found a sufficiently aesthetic replacement yet--but I did note the intersection."
"Oh, cool, what was the intersection?"
She names it. "--But we were actually about half a block away from the intersection itself when I sensed you all."
"Still a decent ballpark. Okay, that might be longer than your swarm sense, I wonder if it works on swarms."
"I sincerely hope so."
"You wanna be a swarm hunter?"
"No, I simply want the maximum warning possible. Additionally, I prefer to have more rather than less information as a general principle."
"I can't fault you there."
