Isabella Cruz showed up on a Tuesday, which Ethan would later think was a strange detail to remember so clearly, except that everything about that week had gotten weirdly vivid to him, like someone had turned the contrast up on his whole life.
Mr. Harris introduced her the way teachers introduced new students, which is to say badly "This is Isabella, she just moved here, be nice" and then immediately moved on like the matter was closed. Isabella didn't seem bothered by the lack of ceremony. She found the one open seat, near the back by the windows, and sat down without looking at anyone, which somehow drew more attention than if she'd made eye contact with the whole room.
She was pretty in a way that felt almost incidental to her, like it wasn't something she was interested in doing anything with. Dark hair pulled back tight, posture too straight for a high schooler slouched into plastic chairs six hours a day, a stillness to her that made the rest of the class look fidgety by comparison.
"New girl's kind of intense," Jason whispered, not quietly enough.
"You say that about everyone who doesn't laugh at your jokes."
"She hasn't even heard my jokes yet. That's just, like, baseline intense."
Ethan didn't think much more about it until lunch, when he ended up more or less accidentally sitting one table over from her not on purpose, just where the crowd had pushed him and got his first real look at what "intense" actually meant on her. She had a textbook open next to her tray, not one of theirs, something with a cover he didn't recognize, dense with diagrams of stances and joint angles that looked more like an anatomy book than anything school-assigned.
She caught him looking. Ethan looked away too slowly to pretend he hadn't been.
"You always stare at people's lunch reading?" she asked. Not hostile, exactly. Just flat, like she was genuinely asking for information.
"Sorry. Force of habit. What is that?"
"Martial arts manual."
"You do martial arts?"
"My family runs a dojo." She said it the way someone says their family runs a dry cleaner's a fact, no particular weight attached, though something in the set of her jaw suggested there was more underneath it that she wasn't planning on getting into over cafeteria pizza with a stranger.
"That's cool," Ethan said, and meant it, though he had approximately zero context for how cool it actually was.
"It's a lot of work," she said, in a tone that closed the subject, and went back to her book.
He didn't push it. He'd never been great at pushing conversations that didn't want to keep going, and something about Isabella Cruz suggested pushing wouldn't get him anywhere productive anyway. He went back to his own lunch, and his own thoughts, which had mostly settled into a low background hum since the dream a constant, quiet awareness of the System sitting there, waiting to be used, like a tool in a drawer he hadn't decided yet how far he was willing to take out.
He glanced at her book again once, just once, close enough to catch a diagram of two figures locked in some kind of throw, one leg swept behind the other's ankle, weight shifted forward past the point of balance.
He understood it. Immediately, completely, the way he'd understood chapter fourteen. Not from reading the caption he was too far away to read anything but from just looking at the picture, the angles of it, the mechanics laid bare in his head like someone had traced them there in marker.
He blinked and looked away fast, heart going a little quicker than lunch period usually called for.
Observing any technique that had been in the dream too, hadn't it. He'd assumed, without really examining the assumption, that it meant watching someone actually move. Not a diagram in a book three feet away.
He didn't test it further. Not there, not with Isabella Cruz two feet from noticing him staring at her book for the second time in five minutes. But he carried the throw around in his head for the rest of the day anyway, turning it over, understanding it the way you understand a math proof you've never once tried to write out by hand — clear, complete, and entirely untested against anything real.
