Pain came before memory.

Sergeant Nathan Cole opened his eyes to the dim gray of the Afghan mountains. His ears rang like he’d been too close to an explosion. The air smelled of gunpowder and damp earth. He tried to take a deep breath—his chest flared with pain.

“Damn it…” he rasped, rolling onto his side.

Fragments came back in flashes—gunfire, shouting, muzzle flashes from the ridgeline. An ambush. His team had been on patrol when they were hit from both sides.

Then… nothing.

Cole pushed himself up.

And saw them.

His entire squad lay scattered across the ground. No movement.

“No…” his voice cracked.

He crawled to the nearest body—Harris. Eyes open. Empty.

Cole checked for a pulse.

Nothing.

He swallowed hard. Another man. Then another.

All of them were dead.

All of them.

He was the only one left.

—

“Not exactly.”

The voice came from behind him.

Cole spun, rifle up on instinct.

A soldier stood there.

Alive.

Uninjured.

“Lower your weapon, Sergeant,” the man said calmly. “I’m not the enemy.”

Cole didn’t move. His eyes scanned—U.S. uniform, full gear, no visible wounds.

“Who are you?” Cole demanded.

The man frowned slightly. “You’re kidding, right?”

“I said—who are you?”

“Private Daniel Brooks. Same unit as you.”

Cole’s grip tightened.

“No,” he said. “There’s no Brooks in my unit.”

A pause.

Brooks looked at him, confused. “We’ve been deployed together for three months.”

Cole shook his head. “I know every man on my team.”

“Then maybe you’re the one forgetting,” Brooks replied evenly.

—

Cole didn’t know what to believe.

A survivor should have been a relief.

But something was wrong.

He’d served with this team for over a year.

There was no Brooks.

There couldn’t be.

—

“We need to move,” Brooks said, scanning the area. “They might come back.”

Cole hesitated.

But staying here wasn’t an option.

“Fine,” he said. “We move.”

—

They left the ambush site, moving through rocky slopes and dry brush. The sun began to rise, pale light cutting through the haze.

Cole took point—but kept watching Brooks.

The man moved too… perfectly.

No wasted motion. No hesitation.

Like he always knew exactly what to do.

—

“How far to base?” Cole asked.

“About six kilometers west,” Brooks answered immediately.

Cole glanced at him. “You sure?”

“I checked the map before we stepped off.”

Cole didn’t remember that.

They stopped to rest behind a large rock.

Cole drank from his canteen, never letting go of his rifle.

“You said we’ve been working together three months,” Cole said.

“Yeah.”

“Name the squad leader.”

Brooks didn’t hesitate. “Lieutenant Mercer.”

Cole nodded. Correct.

“Primary gunner?”

“Harris.”

“Medic?”

“Lopez.”

All correct.

Too correct.

—

“Then why don’t I remember you?” Cole asked.

Brooks studied him.

“I don’t think I’m the problem,” he said.

“What’s that supposed to mean?”

“It means… maybe you lost something.”

Cole let out a dry laugh. “I’m not brain-damaged.”

“You just survived an explosion,” Brooks replied. “It happens.”

Cole fell silent.

It wasn’t impossible.

But—

“Then why do I remember everyone else… except you?”

Brooks didn’t answer.

—

They kept moving.

The silence between them grew heavier.

—

By midday, they reached a ridge overlooking a valley.

There—something.

A small encampment.

Cole raised his binoculars.

“That’s not our base,” he said.

“No,” Brooks replied. “That’s where we’re going.”

Cole turned. “What?”

“Fallback extraction point.”

Cole shook his head. “That was never in the plan.”

“It was,” Brooks said. “You just don’t remember.”

—

Cole lowered the binoculars.

“What are you hiding from me?”

Brooks exhaled softly.

“Not here,” he said. “We need to get down there first.”

—

Cole didn’t like this.

But he didn’t have a better option.

—

They approached the camp by late afternoon.

No guards.

No flag.

Just a few tents and a comms unit.

Too quiet.

—

“This isn’t right,” Cole muttered.

Brooks didn’t respond. He walked straight in.

Cole followed, weapon ready.

—

Inside the main tent—a laptop still running.

A file open.

Brooks turned the screen toward him.

“You need to see this,” he said.

Cole stepped closer.

The screen showed a report.

UNIT: RECON TEAM ALPHA
MISSION STATUS: TERMINATED

A list of names.

Mercer. Harris. Lopez…

And—

Cole, Nathan – KIA

Cole froze.

“No… that’s wrong…”

He scrolled.

Another line.

SURVIVOR: SUBJECT B-17

Cole looked up at Brooks.

“Subject… what?”

Brooks met his gaze.

“That’s me.”

—

“You’re not a soldier,” Cole said, voice cold.

“Not the way you think.”

“What are you?”

Brooks paused.

“An experiment,” he said. “I was inserted into your unit before deployment.”

“For what?”

“Observation. Support. And… replacement if necessary.”

Cole tightened his grip on the rifle.

“Replacement?”

“In case the unit was wiped out… I would be the one to continue the mission.”

Silence.

“What about my memories—”

“Altered,” Brooks said. “So you wouldn’t know I existed.”

—

Cole took a step back.

“No… that’s not possible…”

“You remember everything else, right?” Brooks said. “Just not me.”

Cole didn’t answer.

Because it was true.

—

“So what’s the mission?” Cole asked.

Brooks looked at him.

“Not elimination.”

“Then what?”

“To observe how a human reacts… when they’re the last one left.”

Cole felt his blood run cold.

“What did you say?”

“The ambush wasn’t an accident,” Brooks said. “It was staged.”

“You’re telling me our own military—”

“Is testing.”

—

Cole raised his rifle, aiming straight at Brooks.

“You expect me to believe that?”

“I don’t need you to believe,” Brooks said. “Just remember.”

—

A sharp pain hit Cole’s head again.

Images flashed—

A white room.

People in lab coats.

A voice:

“Subject C-12 ready.”

Cole dropped to his knees.

“No…”

—

“You’re a subject too,” Brooks said quietly.

Cole looked up, eyes wide.

“No…”

“You’re not just a soldier,” Brooks continued. “You’re part of this experiment.”

Cole shook his head violently.

“I remember my life—”

“Memories can be created.”

—

Silence.

Only the wind outside the tent.

—

Cole looked at his hands.

The scars.

The memories.

The battles.

All of it…

Could be fake?

—

“Then… who’s real?” he asked.

Brooks didn’t answer right away.

“Maybe… none of us,” he said.

—

Cole laughed.

A hollow, empty sound.

“Great,” he whispered. “My whole life… a test.”

—

“Not entirely,” Brooks said. “Your choices are still yours.”

Cole looked at him.

“Then what’s my choice now?”

—

Brooks glanced outside.

“Complete the mission.”

“Or?”

“Walk away… and disappear.”

—

Cole looked at his rifle.

Then at Brooks.

Then at the sky.

—

A soldier.

A truth.

A choice.

—

The sound of a helicopter echoed in the distance.

—

Cole closed his eyes.

Took a deep breath.

—

When he opened them—

he had decided.

—

But no one would ever know—

what he chose.
