The Note Left Behind

The Teacher Notices

Nathan hadn't expected to feel it so quickly — the shift in how Callahan looked at them.

It started small. A glance held a half-second too long during morning announcements, when Nathan happened to walk past his classroom door. A comment in the hallway, friendly on the surface, that felt like it was testing something. "You two have been spending a lot of time in the archive room," Callahan said one Tuesday, easy smile in place, eyes not quite matching it. "Big project."

"Yearbooks," Sasha said, with a breeziness Nathan didn't fully believe but admired anyway. "For the anniversary thing."

"Right. Of course." Callahan's smile didn't move, but something behind it did — a flicker, there and gone, like a door someone had almost forgotten to close. "Let me know if you need anything."

It was nothing. It was completely ordinary, the kind of small-talk teachers made in hallways every day.

It also made the hair on the back of Nathan's neck stand up, in a way he couldn't fully explain even to himself.

"He knows," Sasha said later, once they were safely out of earshot, voice pitched low even though there was no one around to overhear.

"He doesn't know anything. He's guessing, same as we were a week ago."

"Guessing is enough," Sasha said, "if you're the one with something to hide."

They'd started being more careful after the parking lot conversation with Marissa — avoiding the archive room during hours when Callahan might reasonably wander past, talking about the investigation only at the treehouse or over texts they deleted immediately after reading. It felt paranoid, until moments like this one confirmed the paranoia wasn't misplaced at all.

"Do you think he's talked to anyone?" Nathan asked. "Draper, maybe, if she's still involved?"

"I don't know. Maybe. Probably." Sasha's jaw tightened, some of her usual bravado thinning under the weight of the question. "That's what scares me most, honestly. Not him. The idea that there's a whole network of people who already know, who've already decided this is worth protecting."

Nathan thought about Principal Voss, about the easy, comfortable way the school had always run, never once suggesting anything beneath the surface was anything other than ordinary. "We don't know that Voss is involved."

"We don't know that he isn't, either."

It was an uncomfortable thought to carry through the rest of the school day — the sense that the building itself, every hallway and office and familiar face, might be hiding more than either of them had ever imagined possible.

Nathan found himself watching people differently after that — the guidance counselor who always seemed to know exactly which students were struggling, the front office secretary who'd worked there longer than most of the current staff combined, even Principal Voss himself, whose easy authority had always felt reassuring before and now felt, faintly, like something else entirely.

"You're spiraling," Sasha said at lunch, watching him pick apart a sandwich he clearly wasn't eating.

"I'm being thorough."

"You're spiraling thoroughly, then." She nudged his tray back toward him. "Eat something. We can't do this if you fall over from hunger halfway through cross-referencing staff rosters."

"Is that a real concern of yours?"

"Everything's a real concern of mine right now," Sasha admitted, and for once there was no humor underneath it at all.
