The gap didn't stop growing.
It stabilized—
just enough to become usable.
Arjun stepped forward.
Controlled.
Minimal.
The pressure held.
Stable.
Efficiency: 91%
Behind him—
movement slowed.
Not because they stopped—
because they couldn't keep up.
Kabir stepped.
Measured.
Delay.
Efficiency: 64%
Aarav pushed.
Blocked.
Efficiency: 42%
The boy tried—
failed.
Efficiency: 39%
Silence.
They weren't syncing anymore.
They weren't even close.
"…We can't move like this," Aarav said.
Kabir didn't answer.
He was watching something else.
Not the space.
Not the movement.
Timing.
"…There's a delay," he said.
Arjun didn't turn.
"…There always was."
Kabir shook his head.
"…No."
A pause.
"…A gap."
The word stayed.
Different.
Precise.
Kabir stepped forward.
Late.
The pressure hit—
but lighter.
His value increased.
Efficiency: 69%
He stopped.
"…There."
Silence.
Arjun watched.
Not his step—
the moment before it.
Kabir moved again.
Waited—
then stepped.
Clean.
No resistance.
Efficiency: 73%
"…Timing shift," Arjun said.
Kabir nodded.
"…No."
A pause.
"…Reaction window."
The term settled.
Clear.
Usable.
The pressure wasn't constant.
It wasn't random.
It opened—
for a moment.
Then closed.
Arjun stepped again.
Waited—
half-second.
Then moved.
Clean.
Efficiency: 93%
"…Confirmed."
Aarav frowned.
"…So we just wait?"
Kabir shook his head.
"…No."
A pause.
"…We react."
The difference mattered.
Waiting—
passive.
Reaction—
precise.
The boy tried.
Waited too long.
Step—
blocked.
Efficiency: 35%
"…Missed it."
Oru stepped once.
Perfect timing.
No resistance.
Efficiency: 94%
He stopped.
"…Short."
The window.
Short.
Unstable.
Easy to miss.
Arjun stepped again.
Timed it.
Clean.
Then—
next step—
he missed it.
Resistance hit.
Efficiency: 88%
"…Not consistent."
Kabir checked.
[Reaction Window Duration: Variable]
"…It changes."
Of course it did.
Nothing stayed stable here.
Aarav stepped—
wrong timing.
Blocked.
"…This is annoying."
He tried again—
faster.
Missed again.
Blocked.
"…Worse."
Kabir stepped—
timed it better.
Partial success.
Efficiency: 71%
"…Improving."
But still behind.
Far behind.
Arjun stepped again.
Perfect.
Efficiency: 95%
The gap widened.
Again.
The reaction window didn't close the gap.
It exposed it further.
Because now—
skill mattered.
Not just control.
Not just stability.
Precision.
The boy stepped again.
Too early.
Blocked.
"…I can't catch it."
Aarav tried.
Too late.
Blocked.
"…This is useless."
Kabir adjusted.
Focused.
Watched the pattern.
Waited—
then stepped.
Clean.
Efficiency: 76%
"…It's readable."
Arjun shook his head.
"…No."
A pause.
"…It's predictable for you."
Silence.
That was worse.
The window wasn't equal.
It wasn't shared.
It was—
individual.
Oru stepped.
Perfect.
Every time.
Anaya moved—
same result.
Consistent.
Stable.
Aarav failed again.
The boy failed again.
Kabir improved—
slowly.
Arjun—
near perfect.
The gap didn't shrink.
It adapted.
"…We can't use this together," Kabir said.
No one argued.
Because it was obvious now.
Even with the window—
they weren't aligned.
They couldn't move—
as one.
Arjun stepped forward.
Alone.
Timed perfectly.
Efficiency: 96%
Behind him—
they struggled.
Missed.
Failed.
Lagged.
The reaction window didn't save them.
It separated them—
faster.
Arjun stopped.
Looked ahead.
Then—
finally—
spoke.
"…We stop moving together."
Silence.
No one resisted.
Because they already knew.
The window existed.
But not for all of them.
Not at the same time.
Not at the same level.
The system didn't help them.
It didn't guide them.
It didn't synchronize.
It only—
measured their reactions.
And rewarded—
those who didn't miss.
Arjun stepped forward again.
Perfect timing.
Clean.
Behind him—
they missed it.
Again.
And this time—
no one tried to follow.
