Avengers Tower never truly slept.
Even at two in the morning, the enormous structure remained alive.
Deep beneath the public floors, S.H.I.E.L.D. personnel worked behind layers of security, processing intelligence gathered from across the world. Several floors above them, the Hope Organisation's laboratories remained illuminated, filled with scientists who seemed incapable of believing that midnight was a reasonable time to stop working.
The Avengers had long ago stopped questioning it.
The Tower was more than their headquarters now.
It was a home.
A laboratory.
A command center.
A refuge.
S.H.I.E.L.D. and the Hope Organisation operated from different secured sections of the same building, while the Avengers occupied the upper levels.
It was one of the safest places on Earth.
Tonight, however, something hidden within its walls was about to become one of its greatest secrets.
The S.H.I.E.L.D. archive level was almost completely dark.
Only one room remained illuminated.
Inside stood Steve Rogers and Natasha Romanoff.
Neither spoke.
A monitor glowed in front of them.
On the screen was an old timestamp.
DECEMBER 16, 1991.
Steve stared at it.
Something about the date disturbed him.
He couldn't explain why.
Natasha noticed.
"You know that date?"
Steve shook his head.
"No."
"But?"
"I don't know."
Natasha looked back at the screen.
"Neither do I."
The file had been buried deep inside S.H.I.E.L.D.'s oldest intelligence archives.
It wasn't properly labeled.
It wasn't connected to the modern Winter Soldier files.
It had been hidden beneath layers of corrupted data and obsolete classification systems.
Natasha had discovered it while investigating remaining Hydra operations.
At first, she had thought it was simply another forgotten record.
Then she had seen the image.
A man standing inside a Hydra facility.
Long hair.
Dark uniform.
Metal arm.
Her instincts had immediately recognized him.
Bucky Barnes.
The Winter Soldier.
Steve had been brought in because Natasha knew there was no way she could watch it alone.
Now both of them stood before it.
Steve quietly said,
"Play it."
Natasha pressed the button.
The screen flickered.
The recording began.
December 16, 1991
A dark room.
The recording quality was poor.
The camera was positioned in a corner.
Several Hydra agents stood around a table.
One of them spoke.
"Asset is ready."
A door opened.
Bucky Barnes entered.
Steve's breathing stopped.
Even after everything he had seen, nothing had prepared him for this.
Bucky looked younger.
Not much.
But enough.
His hair was longer.
His face was thinner.
His eyes were completely empty.
The man Steve remembered was still somewhere beneath that expression.
But Hydra had buried him.
One of the operatives approached.
"Mission briefing."
Bucky stood motionless.
The operative placed a photograph on the table.
"Target?"
"A vehicle."
"What is it carrying?"
"Experimental material."
"Destination?"
"Siberia."
"When?"
"0200."
"Security?"
"Four armed guards."
"Additional personnel?"
"Unknown."
The operative leaned forward.
"Your orders are simple."
Bucky waited.
"Intercept the vehicle."
A pause.
"Secure the cargo."
Another pause.
"Eliminate anyone who interferes."
Bucky answered immediately.
"Understood."
Steve's hands slowly curled into fists.
Natasha glanced at him.
She knew what he was thinking.
Bucky hadn't been fighting for Hydra.
He hadn't been fighting because he wanted to.
He had been programmed.
The footage changed.
Snow covered a deserted road.
A vehicle moved through the darkness.
Then the Winter Soldier appeared.
The attack was almost instantaneous.
One guard fired.
Bucky moved.
The bullet missed.
The soldier's weapon was gone before he could fire again.
Another guard attacked.
Bucky struck him down.
A third tried to escape.
Bucky caught him.
The fourth barely had time to raise his gun.
Bucky disarmed him.
There was no rage.
No hesitation.
No satisfaction.
Nothing.
Only efficiency.
Steve looked away for a moment.
He had fought Bucky.
He had fought the Winter Soldier.
But seeing the operation from the beginning was different.
This wasn't a man fighting.
It was a weapon executing an instruction.
The vehicle crashed.
Bucky walked toward it.
He tore open the rear doors.
Inside were several metal containers.
One had fallen over.
A case had broken open.
Several glass vials were visible.
Steve leaned forward.
His eyes widened.
"Serum."
Natasha immediately recognized the markings.
"Super-soldier serum."
The label became visible.
PROJECT: REPLICATION.
Steve's expression hardened.
Hydra hadn't merely been moving weapons.
They were transporting super-soldier serum.
The same serum that had created Captain America.
Bucky lifted the case.
A voice came through his radio.
"Confirm extraction."
Bucky looked at the container.
"Cargo secured."
"Proceed to secondary facility."
Bucky turned.
The screen suddenly distorted.
Static filled the room.
Then—
Black.
Steve immediately turned toward Natasha.
"That's not the whole recording."
"No."
"How much?"
"At least several minutes."
"Can you recover it?"
Natasha stared at the system.
"I've already tried."
Steve looked at her.
"Try again."
"I did."
"Natasha."
She sighed.
"Steve, this file has been deliberately damaged."
Steve looked back at the screen.
"Then someone wanted this buried."
"Probably."
"Can you find out who?"
"Not without breaking through several layers of encryption."
Steve was silent.
Then he said,
"We ask KB."
Natasha looked at him.
There was hesitation in her eyes.
"You trust him with this?"
Steve nodded.
"I trust him."
"Even with whatever might be inside?"
Steve looked at the screen.
"I don't know what's inside."
"Exactly."
"Which is why I want to know."
Natasha considered it.
Then nodded.
"All right."
Hope Organisation — Avengers Tower
The elevator opened onto one of the Hope Organisation's advanced research floors.
The atmosphere there was almost surreal compared to the dark S.H.I.E.L.D. archive.
Scientists moved between holographic displays.
Robotic systems carried equipment.
Large transparent screens displayed molecular structures and artificial intelligence models.
At the center of the main laboratory stood KB.
Kabir Morgan was examining a rotating holographic model while Alexa's voice spoke from the surrounding speakers.
"Your current hypothesis has a forty-seven percent probability of being incorrect."
KB smiled.
"Only forty-seven?"
"I could increase your confidence."
"How?"
"I could lie."
KB laughed.
"Very helpful."
Steve and Natasha entered.
KB immediately noticed them.
His smile disappeared.
"Steve. Natasha."
He looked between them.
"What happened?"
Steve placed the encrypted drive on the table.
"We found an old Hydra recording."
KB looked at it.
"How old?"
"1991."
KB's expression became serious.
Steve continued.
"It's Bucky."
KB's eyes narrowed.
"The Winter Soldier?"
"Yes."
Natasha explained everything.
The mission.
The vehicle.
The serum.
The corrupted footage.
The missing sections.
KB listened carefully.
When they finished, he picked up the drive.
"You want me to recover the missing data."
"Yes."
KB nodded.
"Alexa."
"Yes?"
"Analyze the drive."
A holographic interface appeared.
The drive was scanned.
Numbers began moving rapidly across the screen.
Alexa spoke.
"The file has been intentionally corrupted."
Natasha folded her arms.
"Can you reconstruct it?"
"Yes."
Steve asked,
"How long?"
"Approximately four minutes."
KB raised an eyebrow.
"That's optimistic."
Alexa replied,
"I was being polite."
KB smiled.
"Carry on."
The reconstruction began.
Millions of lines of damaged code were analyzed.
Encrypted fragments were separated.
Deleted sections were reconstructed from metadata.
Natasha watched the screen.
Steve watched KB.
Finally Alexa spoke.
"Reconstruction complete."
Steve stepped forward.
"How much?"
"Ninety-eight point seven percent."
Natasha exhaled.
"And the remaining portion?"
"Beyond reliable recovery."
Steve nodded.
"That's enough."
KB looked at them.
"Do you want me to play it?"
Steve hesitated.
Natasha looked at him.
Then she said,
"Yes."
KB nodded.
He activated a secure playback system.
But before the footage began, Natasha said,
"KB."
He looked at her.
"We need to know something."
"What?"
"This could involve someone we know."
KB remained silent.
Steve added,
"We don't know who."
KB understood immediately.
He didn't ask.
Instead, he simply said,
"Then let's watch."
The lights dimmed.
The recording began.
The Truth in the Footage
Bucky walked through a Hydra corridor.
The case containing the serum was in his hand.
Two Hydra agents followed.
They entered a laboratory.
Several scientists immediately surrounded the case.
One opened it.
His eyes widened.
"Intact."
The Hydra commander nodded.
"Begin analysis."
The scientist lifted one vial.
"If the molecular structure remains stable, we can replicate it."
"How long?"
"Years."
The commander frowned.
"We don't have years."
"Then we need more samples."
"And subjects."
The scientist hesitated.
"Yes."
Steve's jaw tightened.
The scientist looked toward Bucky.
"We already have one."
The commander smiled.
"Exactly."
Steve looked away.
KB noticed.
He didn't speak.
Natasha continued watching.
The recording shifted.
Bucky was escorted into another room.
A scientist stood in front of him.
"Do you remember anything?"
Bucky remained silent.
"Your name?"
No answer.
"Who are you?"
Bucky finally answered.
"Winter Soldier."
"Who do you serve?"
"Hydra."
"What do you remember?"
"Nothing."
The scientist looked at the commander.
"Memory degradation is accelerating."
"Then reset him."
Bucky was strapped into a chair.
Machines surrounded him.
The conditioning process began.
Commands were repeated.
Names.
Locations.
Targets.
Hydra.
Winter Soldier.
Obey.
Forget.
Repeat.
Steve's expression became painful.
"He didn't even know who he was."
Natasha said quietly,
"No."
KB remained silent.
The machine stopped.
The Hydra operative approached.
"Who are you?"
"Winter Soldier."
"Who do you serve?"
"Hydra."
"What do you remember?"
"Nothing."
The operative paused.
"Who were you before?"
For the first time, Bucky hesitated.
Something flickered in his eyes.
A memory.
A face.
A name.
Something buried beneath the conditioning.
The operative looked toward the scientist.
"Erase it."
The machine activated again.
Steve's eyes closed.
He couldn't watch.
Natasha kept staring.
KB lowered his gaze.
The footage continued.
A different room.
A different camera.
A Hydra officer entered.
"Asset completed the assignment."
The commander nodded.
"Good."
The officer placed a file on the table.
"There is another matter."
"What?"
"The vehicle."
The commander looked at him.
"The cargo was recovered."
"Not the cargo."
The officer hesitated.
"There was another detail."
The audio crackled.
Steve opened his eyes.
"What detail?"
The recording distorted.
The officer's voice became almost unintelligible.
"...vehicle..."
Static.
"...Stark..."
Steve froze.
Natasha turned toward him.
KB's expression became serious.
The audio returned for less than a second.
"...Howard..."
Then static.
The room went silent.
Steve's face had gone pale.
Natasha stared at the screen.
KB didn't move.
The recording continued.
The officer said something else.
The words were lost.
Another fragment emerged.
"...intercepted..."
Then the footage froze.
Alexa's reconstruction system appeared.
AUDIO RECOVERY: INCOMPLETE.
Steve whispered,
"Play it again."
Alexa replayed the section.
The same fragments emerged.
"...Stark..."
"...Howard..."
"...intercepted..."
Nothing more.
Steve stared at the screen.
Natasha looked toward KB.
KB was silent.
Steve finally turned to him.
"What do you think?"
KB didn't answer immediately.
He looked at the screen.
Then at Steve.
Then Natasha.
"Do you want my opinion?"
Steve nodded.
KB took a breath.
"Then I think you need to be very careful."
Steve frowned.
"Why?"
"Because you have evidence."
KB pointed toward the screen.
"But you don't have the whole story."
Natasha nodded slowly.
"We don't know what happened."
"Exactly."
Steve looked at the frozen image.
"But the date..."
"Matters."
"And the name..."
"Matters."
Steve's voice became quieter.
"But we don't know what either means."
KB nodded.
"Correct."
Silence filled the room.
Then Steve asked the question that had been haunting him since they entered.
"What would you do?"
KB looked at him.
For several seconds, he said nothing.
Then he shook his head.
"That's the wrong question."
Steve frowned.
"Why?"
"Because you're asking me to make a choice that belongs to you."
Steve stared at him.
KB continued.
"You have two people on opposite sides of this truth."
Steve lowered his eyes.
"One is Bucky."
KB nodded.
"Your oldest friend."
Steve said nothing.
"The other is Tony."
The name hung in the room.
Natasha looked away.
KB continued.
"Your friend."
Steve's jaw tightened.
"Whatever you do, someone will be hurt."
Steve looked at him.
"Then what am I supposed to do?"
KB's voice remained calm.
"Choose."
Steve looked confused.
KB continued.
"Not because you know everything."
"Not because you are guaranteed to be right."
"But because they are your friends."
He stepped closer.
"You know Bucky."
"You know Tony."
"You know what each of them has lost."
"You know what each of them can survive."
"And you know what each of them can't."
Steve's eyes became wet.
Natasha remained silent.
KB looked directly at Steve.
"One of your friends will be wronged."
Steve swallowed.
KB's voice softened.
"Who that friend will be..."
He paused.
"...depends on you."
Steve looked down.
KB continued.
"There is no decision here where everyone walks away unharmed."
Steve whispered,
"What if I make the wrong choice?"
KB smiled sadly.
"Then you will have to live with it."
Steve looked at him.
"That's not very comforting."
"No."
KB's expression became gentle.
"But it's honest."
Steve stared at the floor.
KB placed a hand on his shoulder.
"Don't choose because you're afraid of being hated."
Steve looked up.
"Then why should I choose?"
"Because eventually, someone has to."
Steve said nothing.
KB stepped back.
"I can give you information."
"I can help you understand it."
"I can help you find the truth."
Steve and Natasha left the laboratory later that night.
Neither spoke in the elevator.
The doors opened onto the main Avengers level.
Tony was there.
Laughing with Bruce.
Clint was eating.
Sam was arguing about something.
The atmosphere was warm.
Normal.
Tony looked up.
"There you two are."
Steve stopped.
Tony smiled.
"Where have you been?"
Steve stared at him.
For one brief moment, he couldn't see anything except the truth they had just discovered.
Tony Stark.
Howard Stark's son.
His friend.
A man who trusted him.
A man who had no idea that Steve had just watched a recording containing his father's name.
Tony raised an eyebrow.
"Steve?"
Steve forced a smile.
"Archive work."
Tony nodded.
"At this hour?"
Natasha immediately answered,
"Classified."
Tony laughed.
"Of course."
He returned to his conversation.
Steve walked past him.
Natasha followed.
Neither looked back.
The next several days were difficult.
Steve and Natasha continued investigating quietly.
They searched S.H.I.E.L.D. records.
Hydra archives.
Military databases.
Old intelligence reports.
Everywhere they looked, the same problem appeared.
December 16, 1991.
Missing files.
Restricted records.
Deleted information.
They found a classified file connected to Howard Stark.
They couldn't access it.
They found references to the Winter Soldier.
They couldn't establish the complete connection.
They found fragments.
Never the whole truth.
And that uncertainty became the reason they remained silent.
They couldn't tell Tony based on a few damaged words.
Not yet.
So they made a decision.
Nobody would know.
Not Fury.
Not Clint.
Not Bruce.
Not Sam.
Not Tony.
And not even KB.
KB had given them the tools.
He had watched the footage.
He had given Steve his opinion.
Then he had left the decision with him.
He never asked what they had decided.
The Secret
Time passed.
The Avengers continued fighting.
The Tower continued growing.
S.H.I.E.L.D. and Hope Organisation continued operating under the same roof.
Tony continued building.
Steve continued searching for Bucky.
Natasha continued investigating.
And the recording remained locked.
Sometimes Steve would see Tony laughing.
Sometimes Natasha would sit beside him during briefings.
Sometimes Howard Stark's name would appear in conversation.
Every time, they remembered the recording.
The snowy road.
The Winter Soldier.
The serum.
The damaged audio.
The two words.
Stark.
Howard.
But they still didn't know what they meant.
So they waited.
Avengers Tower had become quieter since the incident in Sokovia.
Not peaceful.
Just quieter.
The kind of quiet that existed between storms.
On one of the highest secured floors of the Hope Organisation's research division, KB stood before a transparent chamber filled with pale golden light.
Inside the chamber sat a small metallic cylinder.
It looked almost insignificant.
But the equations surrounding it covered half the laboratory.
Alexa monitored hundreds of variables while KB adjusted a holographic molecular model.
"Increase photon absorption by three percent," KB said.
"That would increase cellular stress by eleven percent," Alexa replied.
"Then reduce the conversion rate."
"That will lower the enhancement."
"Acceptable."
Alexa paused.
"You are deliberately reducing the efficiency."
"Yes."
"Why?"
KB looked at the cylinder.
"Because stronger isn't always better."
Alexa remained silent.
KB smiled faintly.
"That's something humanity keeps forgetting."
The project had no public name.
KB had deliberately kept it that way.
There was no announcement.
No government proposal.
No Avengers briefing.
Not even Tony knew the complete details.
It was still experimental.
Barely beyond the theoretical stage.
The basic principle was deceptively simple.
Human cells could absorb certain forms of energy.
Sunlight already affected biological processes.
Moonlight, although vastly weaker, carried a different spectrum and a different energetic signature.
KB wanted to create a biological system that could temporarily convert both into usable cellular energy.
Not merely vitamin synthesis.
Not increased stamina.
Something far more ambitious.
A human being who could absorb solar and lunar radiation and convert it into controlled physical enhancement.
Strength.
Durability.
Regeneration.
Energy production.
Perhaps even accelerated recovery.
And when combined with the Nanotech Healer, the possibilities became extraordinary.
The Nanotech Healer could repair damaged tissue at microscopic levels.
The serum would provide the energy necessary for the body to sustain itself.
Together, they could potentially allow an ordinary human being to survive injuries that would normally be fatal.
But KB wasn't trying to create another Captain America.
He wasn't trying to create an army.
He was trying to create something different.
A humanity that could survive without constantly waiting for gods, mutants, aliens, enhanced soldiers, or superheroes to save them.
He knew what the future held.
Wars.
Invaders.
Superpowered conflicts.
Weapons capable of destroying cities.
Threats that ordinary humans could barely comprehend.
And every time humanity encountered such a threat, millions of innocent people remained helpless.
KB hated that.
Not because he believed humans were weak.
Because he believed they deserved the opportunity to stand.
He stared at the serum.
"Alexa."
"Yes?"
"Run the long-term projection."
A holographic timeline appeared.
The results weren't encouraging.
Organ failure.
Cellular instability.
Mutation.
Energy overload.
KB studied every possibility.
"Still too dangerous."
"Agreed."
"How many successful trials?"
"Eight."
"Stable?"
"Four."
"Long-term?"
"Unknown."
KB nodded.
"Then we aren't ready."
Alexa looked at him.
"You have rejected seven potential formulations."
"Because seven could kill someone."
"Your standards are unusually high."
KB smiled.
"My standards are supposed to be high."
He looked through the glass at the serum.
"One day, someone will take this without understanding it."
Alexa's voice became softer.
"You're concerned about misuse."
"I'm concerned about desperation."
KB turned toward the holographic display.
"Give humanity enough power and someone will eventually use it for the wrong reason."
"So why create it?"
KB didn't hesitate.
"Because someone will eventually need it."
The Restriction
KB opened another interface.
A second layer of security appeared.
This wasn't biological.
It was technological.
Every serum vial would contain a nanoscopic authentication system.
The serum would only activate fully under specific conditions.
Medical monitoring.
Biometric compatibility.
Neurological stability.
And most importantly—
Authorization.
No mass production.
No military distribution.
No black-market replication.
No forced experimentation.
The system would recognize unauthorized extraction and neutralize the active components before they could be used.
KB stared at the restriction protocol.
"Humanity needs power."
Alexa answered,
"Power without restriction creates risk."
KB nodded.
"Exactly."
He added another condition.
THE SERUM MUST NEVER BE USED TO SUBJUGATE HUMANITY.
Another.
NO MILITARY DEPLOYMENT WITHOUT INTERNATIONAL OVERSIGHT.
Another.
NO HUMAN EXPERIMENTATION WITHOUT CONSENT.
And finally—
THE SERUM EXISTS TO PROTECT HUMAN LIFE, NOT TO CREATE RULERS.
KB looked at the words.
"Lock it."
Alexa complied.
"Authorization required."
"From whom?"
KB smiled.
"From me."
Alexa paused.
"That creates a single point of failure."
"I know."
"Why?"
"Because until humanity learns how to govern power responsibly, someone has to make sure the power doesn't govern humanity."
Alexa considered this.
"That sounds contradictory."
"It is."
KB looked toward the window.
"Humanity is contradictory."
Lagos,
Thousands of kilometers away, the situation was far less philosophical.
It was chaos.
Gunfire echoed through the streets of Lagos.
Civilians ran for cover.
Vehicles were abandoned.
A group of armed men moved through a heavily secured facility.
At their center was a familiar face.
Brock Rumlow.
Captain America stood across from him.
His shield was raised.
"Rumlow."
Rumlow smiled.
"Still playing hero, Rogers?"
Steve didn't answer.
Natasha moved through the building behind him.
Sam Wilson flew overhead.
Wanda stood several meters away, concentrating.
Pietro was already moving through the corridors.
The target was simple.
A biological weapon.
Rumlow's men had broken into a laboratory and were attempting to steal it.
The Avengers had arrived before they could escape.
"Sam," Steve ordered.
"On it."
Falcon dove toward a fleeing mercenary.
Pietro appeared beside another.
The man's weapon disappeared from his hand before he even realized what had happened.
Natasha took down two more.
Steve advanced toward Rumlow.
The two collided.
Shield against reinforced gauntlet.
Rumlow struck.
Steve blocked.
"You always were stubborn," Rumlow growled.
Steve pushed him back.
"You talk too much."
Rumlow laughed.
The battle intensified.
The Avengers slowly gained control.
But Rumlow had one final card.
He knew he wasn't getting out.
So he made a different decision.
If he couldn't escape—
He would take Rogers with him.
Steve saw the device too late.
Rumlow activated it.
"Steve!"
Natasha shouted.
Steve turned.
A massive explosion erupted.
Wanda's eyes widened.
"No!"
She threw both hands forward.
Her telekinesis caught the expanding force.
For a fraction of a second, the explosion stopped.
Everyone froze.
Wanda strained.
She could redirect it.
She had to.
She pushed.
The explosion moved.
Away from Steve.
Away from the Avengers.
Toward an empty structure.
Except—
It wasn't empty.
The building was being used by a humanitarian organization.
Wakandan humanitarian workers were inside.
The explosion tore through the structure.
Glass shattered.
Concrete collapsed.
Flames erupted.
Wanda's face went white.
"No..."
Silence followed.
Then screams.
Steve stared at the destroyed building.
Natasha's expression hardened.
Sam landed.
Pietro stopped beside Wanda.
Nobody spoke.
Wanda stared at her hands.
"I..."
Her voice broke.
"I didn't know."
Steve looked at her.
"It wasn't your fault."
But the words sounded hollow.
Wanda shook her head.
"I moved it."
Steve stepped toward her.
"Wanda—"
"I moved it."
She looked at the destroyed building.
People were running toward the wreckage.
Emergency sirens began filling the streets.
"We need to help."
Steve nodded.
"Everyone, move."
The Avengers rushed toward the ruins.
The mission had been successful.
The biological weapon had been recovered.
Rumlow had been stopped.
But none of that mattered to the people standing outside the destroyed building.
Wakandan humanitarian workers had been helping civilians.
They had not been soldiers.
They had not been Avengers.
They had not been part of the fight.
And now they were dead.
Steve stood silently as rescue workers searched through the rubble.
Natasha stood beside him.
Sam removed his helmet.
Pietro looked toward Wanda.
She hadn't moved.
Her eyes remained fixed on the ruins.
"I killed them."
Pietro immediately shook his head.
"No."
"I redirected the explosion."
"You saved Steve."
"I killed them."
"Wanda."
She looked at him.
Pietro stepped closer.
"You were trying to save someone."
Wanda looked back at the ruins.
"That doesn't bring them back."
Pietro had no answer.
Steve heard them.
He looked toward the destruction.
For years, people had called the Avengers heroes.
But today, that word felt meaningless.
Because the dead were still dead.
That night, the Avengers returned to the Tower.
Nobody celebrated.
Nobody joked.
Nobody discussed the successful recovery.
The mood was heavy.
Wanda disappeared into one of the quiet rooms.
Steve stood alone in the common area.
Natasha sat nearby.
Sam looked through mission reports.
Pietro paced.
The images from Lagos continued appearing on every screen.
The world had already begun reacting.
News channels showed the destroyed building.
Casualties.
Civilian deaths.
Political statements.
Questions.
Again and again, the same question appeared.
Who watches the Avengers?
Steve stared at the screen.
He didn't answer.
Across the Tower, KB stood inside his laboratory.
The solar-moon serum remained in its chamber.
He looked at the experiment.
Then at the news.
The footage of Lagos played silently.
The destroyed building.
The casualties.
The terrified civilians.
KB's expression became somber.
Alexa spoke quietly.
"The experiment can continue."
KB didn't answer.
"The current formulation is promising."
KB continued staring at Lagos.
Finally he said,
"Pause the project."
Alexa hesitated.
"For how long?"
"Until we understand the failure."
"The serum wasn't involved."
"I know."
KB looked at the ruined building.
"That's exactly why."
Alexa remained silent.
KB turned toward the serum.
He had been trying to give humanity greater strength.
But strength alone wouldn't solve anything.
He had always known that.
Yet seeing the consequences of power—even power used with good intentions—made the lesson sharper.
He walked toward the chamber.
"Alexa."
"Yes?"
"Add another restriction."
"What kind?"
KB stared at the serum.
"Psychological screening."
"That wasn't part of the original design."
"It is now."
"Any other modifications?"
KB thought for a moment.
"Emergency neutralization."
"If the user becomes hostile?"
"If the serum is deliberately being used to harm civilians."
Alexa processed the instruction.
"That is difficult to define."
"I know."
KB looked toward the laboratory doors.
"That's why we'll keep working on it."
He wasn't abandoning the project.
He couldn't.
The future still terrified him.
He knew what was coming.
Humanity would face wars that would make Lagos look small.
Alien invasions.
Artificial intelligence.
Enhanced individuals.
Cosmic threats.
And ordinary people would still be standing in the middle of it.
KB couldn't accept that.
He didn't want humanity dependent on superheroes forever.
He wanted humans to eventually stand beside them.
Not beneath them.
But Lagos had reminded him of something equally important.
Power had consequences.
Even when wielded by someone trying to save lives.
KB closed the serum chamber.
"Continue testing."
Alexa nodded.
"Understood."
KB looked once more toward the city.
"Humanity needs strength."
He paused.
"But first..."
His expression became thoughtful.
"...we need wisdom."
Later that night, Steve found Wanda alone.
She was sitting beside a window.
The city lights reflected in her eyes.
Steve approached quietly.
"Wanda."
She didn't look at him.
"I killed them."
Steve sat beside her.
"You saved me."
"And killed them."
Steve remained silent.
After several seconds, he said,
"Today wasn't about heroes and villains."
Wanda finally looked at him.
"It wasn't?"
"No."
Steve looked toward the city.
"It was about people trying to stop something terrible."
He paused.
"And people got hurt."
Wanda lowered her head.
Steve continued.
"That doesn't make you a monster."
"But it doesn't make me innocent."
Steve didn't deny it.
"No."
Wanda looked surprised.
Steve continued.
"Being an Avenger doesn't mean we're incapable of mistakes."
She looked at him.
"It means we have to learn from them."
Wanda looked back toward the city.
"What happens now?"
Steve didn't answer immediately.
"I don't know."
For once, Captain America had no answer.
By morning, Lagos had become more than an unfortunate mission.
It had become a political crisis.
Governments demanded answers.
Families demanded accountability.
The world wanted guarantees.
Could the Avengers operate without oversight?
Could enhanced individuals be trusted?
Could anyone control them?
And somewhere in the Hope Organisation laboratory, KB watched the debate unfold.
His unfinished serum remained locked away.
His restrictions remained incomplete.
His dream remained unchanged.
Humanity needed the ability to defend itself.
But before humanity could stand on its own ground, it needed to understand what standing meant.
Not domination.
Not superiority.
Not power for its own sake.
Responsibility.
KB looked at the unfinished formula.
He smiled faintly.
"Back to work."
Alexa activated the laboratory.
The experiment resumed.
Outside, the world was changing.
The Avengers had won their battle in Lagos.
But they had lost something far more important.
The certainty that being heroes was enough.
And as the first arguments over the Avengers' future began spreading across governments around the world, KB quietly continued working on a serum that might one day change humanity forever.
He only hoped that when that day came—
Humanity would be ready for the power it had been given.
