The floor didn't settle.
It locked.
Metal panels snapped into place beneath their feet with sharp, final clicks, sealing the room into something controlled. The shifting stopped completely, and somehow that felt worse than the chaos before it.
Sarai's stomach tightened.
"…okay," she said slowly, glancing down. "That's not a good sign."
The air changed next.
A low hum spread through the room, subtle at first, then building until it pressed against her ears and settled behind her eyes like pressure before a migraine.
Virek didn't move.
He stood over Keller, breathing steady, watching him like he was deciding whether this ended now or in pieces.
Keller stayed on one knee.
Not rushing.
Not panicking.
Watching right back.
"Now you understand," Keller said.
Virek's jaw tightened.
"I understand you need to die."
Sarai blinked.
"…okay, direct," she muttered. "I like that."
Keller's gaze shifted past him.
"Do you?" he asked. "Then look."
Sarai turned.
The walls lit up.
Not dim. Not subtle. Full panels of light snapped on across the entire room, flooding the space with layered streams of data that moved too fast to process all at once.
Then she saw it.
The shapes.
Two figures mapped in motion.
Her.
Virek.
Every step they'd taken. Every strike. Every hesitation.
Broken down.
Tracked.
Predicted.
"…no," she said quietly.
She stepped closer without thinking, eyes narrowing as the data sharpened.
It wasn't just replaying what they had done.
It was showing what they were about to do.
Highlighted paths. Projected movements. Anticipated strikes.
"…oh hell no."
Keller stood.
"You see it now."
Sarai turned slowly.
"You've been watching us fight," she said.
"Yes."
"And learning from it."
"Yes."
"And using that to—what?" she snapped. "Win fights?"
Keller tilted his head slightly.
"To end them," he said.
Silence hit harder than any impact.
Virek stepped forward.
"You built a system to predict people."
Keller nodded once.
"To control outcomes," he corrected.
Sarai let out a short, disbelieving laugh.
"That's stupid," she said. "People aren't robots."
Keller looked at her like that answer was expected.
"No," he said. "They're patterns."
Sarai's expression tightened.
"That's not the same thing."
"It is under pressure," Keller replied.
He gestured toward the walls.
"People repeat what works. They fall back on what keeps them alive. Over time, those decisions become predictable."
His gaze shifted to Virek.
"You're a perfect example."
That landed.
Sarai looked at Virek.
He didn't react.
But something in his posture changed.
"What's he talking about?" she asked.
Virek didn't answer.
Keller did.
"He's exactly what this system was built on," Keller said. "Operatives. Killers. People trained to respond efficiently under pressure."
Sarai frowned.
"…so you've been studying people like him?"
"I've been refining them," Keller said.
Virek's voice dropped.
"You used them."
"Yes."
Sarai's stomach turned.
"For what?" she demanded.
Keller's gaze sharpened.
"To prove that control is possible," he said. "That if you understand how people respond under pressure, you can predict them… and once you can predict them—"
He took a step forward.
"—you can decide what happens to them."
The room felt colder.
Sarai shook her head.
"That's not control," she said. "That's manipulation."
Keller didn't disagree.
"Yes."
That was worse.
Virek stepped closer, his voice low.
"You've been setting people up to fail."
Keller's eyes flicked to him.
"I've been removing uncertainty."
Sarai scoffed.
"That's the same thing."
Keller ignored her.
"And it worked," he said. "Every time."
His gaze shifted back to her.
"Until you."
Sarai froze.
"…me?"
Keller nodded.
"You don't follow stable patterns," he said. "You change your behavior mid-action. You interrupt your own rhythm. You make inefficient choices that still succeed."
Sarai blinked.
"That's called being human."
Keller stepped closer.
"That's called breaking prediction."
The panels behind him shifted.
Now the data focused only on her.
Her movements.
Her timing.
Her decisions.
Highlighted in red where the system had failed.
Sarai felt her chest tighten.
"…you've been watching me this whole time."
"Yes."
"Why?"
Keller held her gaze.
"Because you shouldn't work."
That hit harder than anything else he'd said.
Sarai frowned.
"…wow," she said slowly. "That's rude."
Virek moved.
Fast.
He closed the distance and struck.
Keller met him.
The fight exploded again.
This time Virek didn't hold anything back.
He drove forward with force, his movements sharper, heavier, more direct. He wasn't testing anymore. He was trying to end it.
Keller gave ground.
Not much.
But enough.
Sarai saw it.
She moved too.
She cut wide instead of stepping in straight, refusing to give Keller a clean line to control both of them.
Keller turned toward her.
That was his mistake.
Sarai stepped in and drove her shoulder into his chest, knocking him off balance just long enough—
Virek struck.
Hard.
The hit landed across Keller's ribs, forcing a real break in his composure.
Sarai caught it.
"Yeah," she said. "You felt that."
Keller stepped back.
Then forward again.
Faster.
He went straight for Sarai.
She tried to react—
but this time he was quicker.
His strike slipped past her guard and slammed into her shoulder, forcing her down hard.
Pain flared sharp and immediate.
"Sarai!"
"I'm fine—"
She wasn't.
Keller moved to finish it.
Virek intercepted him.
Violently.
"You're done."
Keller met him—
but now Virek wasn't holding back at all.
He drove into Keller with relentless pressure, every strike aimed to end the fight.
Keller started to fall behind.
Just slightly.
That was enough.
Virek forced him down to one knee.
Silence hit.
Sarai pushed herself up, breathing hard, her shoulder throbbing.
"Okay," she said. "Now we're talking."
Virek stood over Keller.
Keller looked up at him.
Calm.
Still.
And smiling.
"…why are you smiling," Sarai said immediately.
Keller exhaled.
"Because it worked."
The room shifted.
Not the floor.
The system.
The panels flared back to life—
but this time, the data wasn't just tracking them.
It was spreading.
Projecting outward.
Sarai's stomach dropped.
"…what did you do?"
Keller's voice was quiet.
"I finished it."
Virek's expression hardened.
"You built this for more than just us."
Keller nodded.
"This was a test," he said.
Sarai stared at the walls.
"…a test for what?"
Keller looked at her.
"For scale."
Silence.
Then—
the building shook.
Hard.
Sarai swallowed.
"…yeah," she said. "That sounds like a city problem."
