Chapter Text

Tony Stark had met gods, killers, generals, senators, robots with alarming opinions about workplace safety,

and exactly one man who had tried to sell him a watch while he was actively bleeding out in Monaco.

He had not, however, met Dr. Bruce Banner.

Not properly.

Not yet.

Which was a crime, frankly.

A personal insult.

Possibly academic malpractice.

The man had written the paper on anti-electron collisions that Tony had spent three nights in college arguing with,

two nights disproving in the margins,

and one miserable morning realizing Banner had been right the first time and Tony had been running on caffeine and spite. 

Banner’s work on electromagnetic particle behavior was beautiful in the way only dangerous things could be beautiful:

precise, unstable, elegant, capable of ripping apart every assumption in the room if handled incorrectly.

So naturally, SHIELD had stuck him in a lab under armed surveillance.

Because subtlety was dead, buried, and apparently wearing an eyepatch.

Tony swept into the helicarrier laboratory like he owned it, because posture was half ownership and the other half was acting like the invoice had already cleared.

The room smelled like metal, recycled air, and high-grade paranoia.

Computers hummed.

Screens blinked.

Agents pretended not to watch him and failed with the uniform mediocrity of government employees everywhere.

Bruce Banner stood near one of the main consoles, shoulders slightly rounded, hands careful, expression mild in a way Tony recognized immediately.

Not calm.

Managed.

There was a difference.

Calm meant ease.

Managed meant calculation.

Managed meant every breath had been negotiated before it was allowed to leave the body.

Managed meant knowing exactly where every person in the room stood, how close they were, what they were holding,

and how long it would take for them to decide you were no longer a person.

Tony’s smile sharpened.

Oh, Doctor. Been there.

He let his gaze skim over Banner once, fast enough not to be rude, thorough enough to catalogue the important things.

Loose clothing.

No sudden movements.

Eyes tired but too aware.

Mouth ready to apologize for occupying space.

Pulse elevated, if the twitch in his throat was anything to go by.

The Hulk was not in the room.

Fear was.

Tony knew fear.

He had grown up with it under his skin.

He clapped his hands together once.

“Iridium. It's whats in the glow stick. It's a stabilizing agent; Means the portal won't collapse on itself, like it did at SHIELD.

The rest of the raw materials, Agent Barton can get his hands on pretty easily. Only major component he still needs is a power source. A high energy density, something to kick start the cube.”

Maria Hill turned toward him.

“When did you become an expert in thermonuclear astrophysics?”

“Last night.”

Tony flicked his fingers toward the nearest screen, already moving into the data.

“The packet, Selvig's notes, the Extraction Theory papers. Am I the only one who did the reading?”

Steve Rogers looked at him like Tony had just admitted to reading a menu upside down in Sanskrit.

“Does Loki need any particular kind of power source?”

Banner’s gaze shifted, interest flickering alive beneath the exhaustion.

“He's got to heat the cube to a hundred and twenty million Kelvin just to break through the Coulomb barrier.”

Tony’s grin went real before he could stop it.

“Unless, Selvig has figured out how to stabilize the quantum tunneling effect.”

Banner blinked.

It was small.

Barely anything.

But Tony saw the moment the man recalibrated him.

Not billionaire. Not weapon. Not loud thing in a suit.

Scientist.

“Well,” Banner said, and there was a thread of curiosity there now, cautious but present, “if he could do that he could achieve Heavy Ion Fusion at any reactor on the planet.”

“Finally, someone who speaks English.”

Steve stared between them.

“Is that what just happened?”

Tony stuck out his hand.

Banner looked at it for half a second too long.

Tony did not move.

That mattered.

It had mattered once, to him, when people had learned not to grab.

When Charles had waited.

When Rhodey had waited too, years later, scared and stubborn and still there.

Banner took his hand.

His grip was warm. Human.

Tony shook it once, firm enough to mean it, brief enough not to trap.

“It's good to meet you, Dr. Banner. Your work on anti-electron collisions is unparalleled.”

He paused, because sincerity was a dangerous animal and needed to be muzzled before it bit someone.

“And I'm a huge fan of the way you lose control and turn into an enormous green rage monster.”

Banner looked down.

For one second, Tony hated himself.

Not enough to stop being himself, obviously.

Personal growth had limits.

“Thanks,” Banner said.

There it was again.

That careful voice.

That braced little dip at the end, like he expected the joke to become a knife if he waited long enough.

I’m not afraid of you.

Nobody believed sentences like that.

Sentences like that were too easy.

Howard had said plenty of easy sentences.

Fury too.

Doctors in white coats with clean hands and dirty consciences had said easy sentences while tightening restraints around an eight-year-old’s wrists.

No, fear was not disproven with words.

It had to be starved.

So Tony turned back to the screens and made himself easy, bright, irritating.

The safest version of himself, which was to say the most exhausting one.

The work helped.

The work always helped.

Numbers did not care what his blood was.

Equations did not flinch.

Particle behavior remained particle behavior no matter how badly the rest of the world wanted to classify him as a threat, asset, anomaly, mutant, Stark, weapon, son.

The cube’s output data crawled across the screen in restless blue-white spikes.

Tony leaned closer.

“Oh, you are a moody little nightlight, aren’t you?”

Banner glanced at him.

“The cube,” Tony clarified. “Not you. Though if the lab coat fits.”

“Lab coats are usually optional,” Banner said.

“And yet tragically under-accessorized.”

Tony tapped two commands into the console.

“You ever notice secret organizations always have terrible lighting? Is it budget cuts or aesthetic commitment?”

Banner’s mouth twitched.

Tiny victory.

Tony filed it away.

Across the room, Fury watched through the glass.

Tony felt it before he looked.

A pressure at the back of his skull.

Not telepathy.

God, no.

Charles had a touch like warm sunlight through curtains.

Fury’s stare felt like a gun being assembled in the dark.

Tony did not look up.

He did not need to.

Fury knew what Tony was.

Tony knew Fury knew.

Fury knew Tony knew Fury had known since before Tony had understood there was a word for it.

Mutant.

The first time Tony had heard Fury say it, he had been eight years old and bleeding through a hospital gown.

He’s not a child, Howard. Not biologically, not if this develops the way people are saying. You’re a scientist. You understand containment.

Tony’s fingers paused over the keyboard.

No.

Not now.

He flexed his hand once under the table, small enough nobody would notice.

The kinetic hum of the helicarrier thrummed through the floor, through metal, through bone.

Engines.

Footsteps.

Air circulation.

The whole ship was one giant moving thing, all force and vibration and motion.

Tony could feel it like weather.

He could take it in if he wanted.

He did not want.

He never wanted.

He wanted all the time.

“Stark?” Banner asked quietly.

Tony’s fingers resumed moving.

“Hmm?”

“You stopped typing.”

“Dramatic pause. Very important part of the scientific method. Right between reckless hypothesis and expensive explosion.”

Banner studied him for a second.

Not prying.

Just noticing.

Dangerous man.

Tony liked him immediately.

Which was inconvenient.

They worked.

For a while, the lab settled into something almost comfortable.

Steve came and went.

Hill checked updates.

Agents pretended not to listen.

Tony and Banner built a rhythm around each other with the ease of people who had both spent too much of their lives alone with machines.

Banner was careful with data.

Tony was aggressive.

Banner questioned assumptions.

Tony bullied assumptions until they cried and gave up their secrets.

Between them, the cube began to look less like divine mystery and more like a badly supervised physics problem.

“You know,” Tony said eventually, leaning back in his chair, “you should come by Stark Tower sometime. Top ten floors, all R&D. You'd love it, it's candy land.”

Banner’s expression closed in a way that was almost too practiced to see. “Thanks, but the last time I was in New York I kind of broke...Harlem.”

Ah.

There it was.

Not guilt.

Guilt was simple.

Shame.

Tony tilted his chair back.

“Well, I promise a stress free environment. No tension. No surprises.”

He picked up the miniature electrical prod from the table.

It was a stupid idea.

To be fair, most of his best ideas started there.

Banner looked back at the screen.

Tony jabbed him lightly with it.

“OW!”

The sound cracked through the lab.

Tony watched him closely.

Not the body.

Not really.

Everyone watched Bruce Banner’s body.

Everyone waited for green, for rage, for disaster.

Tony watched his eyes.

Annoyance flashed first.

Then surprise.

Then calculation.

Then restraint.

Control.

Beautiful, stubborn, hard-won control.

Steve’s voice snapped from behind them.

“Hey!”

Tony did not look away from Banner.

“Nothing?”

“Are you nuts?” Steve demanded.

Tony finally glanced at him.

“Jury's out.”

Then back to Banner.

“You really have got a lid on it, haven't you? What's your secret? Mellow jazz? Bongo drums? Huge bag of weed?”

Steve’s jaw tightened.

“Is everything a joke to you?”

“Funny things are.”

“Threatening the safety of everyone on this ship isn't funny. No offense, Doctor.”

Banner, somehow, looked more amused than offended.

“No, it's alright. I wouldn't have come aboard if I couldn't handle pointy things.”

Something in Tony’s chest went still.

Pointy things.

The lab blurred at the edges for half a heartbeat.

Not gone.

Not a cut to somewhere else.

He was still there, still sitting in the chair, still holding the stupid prod, still aware of Steve’s anger and Banner’s pulse and the helicarrier’s engines vibrating through the floor.

But memory opened under him like a trapdoor.

Rhodey’s dorm room had smelled like laundry detergent, instant noodles, and the specific academic despair of MIT in February.

Tony had been fifteen, which meant legally a child, academically a problem.

He had been sitting cross-legged on Rhodey’s floor in a shirt that was not his, because he had spilled solder flux on his own

and Rhodey had thrown fabric at his head with the long-suffering violence of a man who had known Tony Stark for almost four months and was already reconsidering several life choices.

“Do you ever sleep?” Rhodey had asked from his desk.

“Sure.”

“Passing out on a keyboard doesn’t count.”

“Agree to disagree.”

Rhodey had rolled his eyes.

“One day your face is gonna have QWERTY embedded in it.”

“Good. Efficient. Then I’ll never lose my keyboard.”

“You’re impossible.”

“I’m innovative.”

“You’re a menace.”

“I contain multitudes.”

Rhodey had turned then, maybe to throw a pen at him, maybe to continue the sacred tradition of calling him an idiot with increasing affection, and Tony had reached up for the circuit board on the bed.

The borrowed shirt had ridden up.

Just a little.

Enough.

Tony had not noticed until Rhodey stopped breathing.

That was the thing people never understood.

Fear had sounds.

Not always screams.

Sometimes fear was silence arriving too fast.

Tony had looked down.

The scar along his lower ribs was old by then.

Thin and pale.

Surgical.

Too clean to be explained by childhood clumsiness, too deliberate to be ignored.

There were others, but that was the one Rhodey saw first.

Tony yanked the shirt down.

Too fast.

Rhodey’s eyes flicked from his hands to his face.

Tony smiled.

He had a very good smile.

Expensive.

Photographed.

Market tested by tabloids since he was eleven.

Rhodey did not smile back.

“Tones,” he said slowly, “what was that?”

“Appendix.”

“That’s not where your appendix is.”

“Mine was ambitious.”

“Tony.”

And there it was. His name, not as a complaint, not as a joke, not as a warning.

As concern.

Tony hated it.

Concern was worse than anger.

Anger could be fought.

Concern got in through cracks.

He stood too quickly.

“I should go.”

“You don’t have to-”

“Actually, statistically, I do. Places to be, geniuses to humble, professors to disappoint. Busy day.”

Rhodey stood too.

Not blocking the door.

Tony noticed that.

Even panicking, he noticed.

Rhodey didn’t block him in.

“Tony,” he said again, softer.

The room was too small.

The air was too loud.

Somewhere in the building someone dropped a textbook and Tony felt the kinetic impact shiver through the floorboards and up his legs.

He swallowed it by instinct.

The energy vanished into him like water into dry ground.

The lightbulb overhead flickered.

Rhodey looked up.

Then back at Tony.

Tony went cold.

No.

No, no, no.

He backed up, hit the desk, knocked a stack of papers down.

“That was wiring.”

“Tones-”

“Old building. Terrible infrastructure. Honestly, Rhodey, for a military man, you’re very quick to jump to conclusions. Bad habit. Gets people court-martialed. Probably. I’m not clear on the paperwork.”

“Tony.”

“Stop saying my name like that.”

“Like what?”

“Like you’re about to ask a question you already know the answer to.”

Rhodey was quiet for a long second.

Then, carefully, he said,

“Are you hurt?”

Tony laughed.

It came out wrong.

“Currently? Existentially? Historically? You’ll have to narrow that down.”

“Who did that to you?”

The room tilted.

Tony could lie.

He was good at lying.

He had been built out of lies, polished with them, sent into boardrooms wearing them like cufflinks.

He could say Howard.

He could say accident.

He could say nothing.

Instead, something in him cracked just enough for the truth to show teeth.

“You need to forget you saw anything.”

Rhodey’s face changed.

Not fear.

Not disgust.

Understanding, maybe.

The beginning of it.

The shape of a door opening into a room Tony had kept locked.

“Tony,” Rhodey said, very quietly, “what are you?”

There it was.

The question.

The one underneath every other question.

The one Howard had asked with revulsion,

Fury with interest,

doctors with clipboards,

himself in mirrors at three in the morning.

What are you?

Tony’s hands curled into fists.

“I’m leaving.”

Rhodey let him take two steps.

“I’m not asking because I want you gone.”

Tony stopped.

His throat hurt.

Rhodey continued, voice tense now, rough around the edges.

“I’m asking because you look like you’re about to jump out a window, and we’re on the fourth floor, and I know you’d probably survive just to make a point, but I’d rather not test that.”

Tony’s mouth twitched despite himself.

Traitorous thing.

Rhodey saw it.

Of course he did.

Rhodey saw too much.

“I’m not-” Tony started.

The light flickered again.

This time, Rhodey watched Tony’s hands.

Tony shoved them under his arms.

“Don’t.”

“Okay.”

“No, I mean it. Don’t do the thing.”

“What thing?”

“The careful voice thing. The hostage negotiator thing. The ‘approach the unstable Stark before he spooks and takes out a city block’ thing.”

Rhodey’s eyebrows rose.

“Can you take out a city block?”

Tony’s silence answered too loudly.

Rhodey inhaled.

There.

There was the fear.

Tony knew it.

He had been waiting for it.

His whole body recognized it like an old song.

He smiled again, sharp and ugly.

“Yeah. That’s about right.”

“Tones-”

“No, it’s fine. It’s the appropriate response. Really. Gold star. Perfectly normal reaction to finding out your roommate is a genetic horror show.”

“I didn’t say that.”

“You thought it.”

“I didn’t.”

“You will.”

Rhodey looked angry then.

Good. Anger was easier.

“You don’t get to decide that for me.”

Tony stared at him.

The room hummed.

The building creaked.

Somewhere below them, a door slammed.

Energy rolled through the floor and Tony caught it before it could rattle the desk, before Rhodey could notice, before the world could betray him again.

Rhodey noticed anyway.

But he didn’t step back.

“Is that what you do?” he asked. “You absorb impact?”

Tony’s laugh was smaller this time. Tired.

“Among other party tricks.”

“Does it hurt?”

Nobody had ever asked that first.

Not what can it do.

Not how dangerous.

Not how useful.

Does it hurt?

Tony looked away.

“Sometimes.”

Rhodey nodded once, like Tony had given him tactical information and not a piece of his own exposed throat.

“Okay,” 

Tony blinked.

“Okay?”

“Yeah.”

“That’s it?”

“For now.”

“You’re not going to report me?”

Rhodey’s expression went flat.

“To who?”

Tony said nothing.

Rhodey’s face hardened.

“Oh,” he said. “Oh, hell no.”

Tony flinched.

Rhodey saw that too, and his anger changed direction instantly.

Not at Tony.

For Tony.

That was worse.

That was so much worse.

“I’m not going to report you,” Rhodey said, each word deliberate. “I’m not going to tell anyone. I’m not going to ask anything you don’t want to answer tonight. And I’m not going anywhere.”

Tony’s chest went tight.

“Don’t make promises you can’t keep, Rhodes.”

Rhodey gave him a look.

“Watch me,” he said.

Tony had no idea what to do with that.

So naturally, he ruined the moment.

“Very dramatic. Did they teach you that in Air Force Feelings 101?”

Rhodey snorted, helpless and furious.

“You are such an asshole.”

Tony’s shoulders dropped half an inch.

“Yeah,” he said. “But I’m a charming asshole.”

“You’re a scared asshole.”

The words hit too close.

Tony looked at the floor.

Rhodey did not apologize.

Good.

Tony would not have known what to do with that either.

After a moment, Rhodey bent down, picked up the fallen papers, and put them back on the desk.

Then he sat on the edge of the bed, leaving the path to the door clear.

Always clear.

“You can go if you need to,” he said. “But if you stay, I’ll order pizza.”

Tony stared at him.

“That’s your strategy?”

“Yep.”

“Pizza.”

“Powerful tool.”

“I reveal deeply classified nightmare genetics and your response is pepperoni?”

“Don’t be ridiculous.” Rhodey picked up the phone. “You’re a vegetarian when stressed.”

Tony’s breath caught.

Because Rhodey knew that.

Because Rhodey had noticed.

Because Rhodey was afraid and staying anyway.

Tony sat back down on the floor before his legs could do something embarrassing, like collapse.

“Extra olives,” he muttered.

Rhodey smiled into the phone.

The memory folded back into the lab around the exact shape of Steve’s anger.

Tony was still holding the electrical prod.

Banner was still looking at him with that mild, exhausted patience.

Steve was still waiting for Tony to justify himself.

“You're tiptoeing, big man,” Tony said, voice only slightly rough. He covered it with a grin. “You need to strut.”

Banner looked at him.

For a second, Tony wondered if Bruce had seen something.

Not the memory, obviously.

Bruce wasn’t that kind of doctor.

But maybe the afterimage.

The little fracture in the mask.

Then Banner’s mouth twitched again.

“You have a strange way of encouraging people.”

“I’m a pioneer.”

“You’re a hazard.”

“Multidisciplinary.”

Steve crossed his arms.

“Threatening him isn’t encouragement.”

Tony turned in his chair.

“Relax, Capsicle. If I wanted to threaten him, there’d be branding, lighting, and a much better soundtrack.”

Steve did not look amused.

Shocking.

The cube data pulsed again on the screen.

Banner shifted back toward it, and Tony followed because science was safer than feelings and had fewer disappointed super soldiers.

For several minutes, they worked in tense quiet.

Well, relatively quiet.

Tony narrated under his breath because silence gave memories room to stretch.

“Okay, glowstick of destiny, talk to me. What are you powering? Portal? Bomb? Interdimensional Roomba?”

Banner adjusted a projection.

“The gamma readings are consistent, but the output spikes don’t behave like a conventional reactor.”

“Because it’s not a reactor. It’s a tantrum in cube form.”

“It’s holding a stable energy state.”

“So a disciplined tantrum.”

Banner huffed.

Tony looked up, triumphant.

“Was that a laugh?”

“No.”

“That was absolutely a laugh. Tiny one. Practically microscopic. Good thing I’m a scientist.”

“It was an exhale.”

“A joyful exhale.”

“It was carbon dioxide.”

“Joyful carbon dioxide.”

Steve’s patience made a sound like a bridge cable snapping.

“Can we focus?”

Tony pointed at the screen.

“We are focused. This is what focused looks like when it’s not wearing spangles.”

Banner’s fingers paused.

Tony saw it a second too late.

Steve saw it too,

maybe,

or maybe he only saw Tony being Tony and Bruce being Bruce and the world being too complicated for a man who had woken up to find everything he knew dead or weaponized.

“Loki’s plan isn’t a joke,” Steve said.

“No,” Tony agreed, because it wasn’t. “It’s an ACME dynamite kit with delusions of grandeur.”

Banner glanced at him.

Steve frowned.

“What?”

Tony waved a hand.

“Cartoon reference. Ask someone born after penicillin.”

Steve’s jaw tightened.

“You think this is funny?”

Tony leaned back.

There it was again.

The moral disappointment.

Clean, square, old-fashioned.

Howard had loved that look on Captain America.

Had carried it around in stories like a religious relic.

Captain America would have done this.

Captain America would have understood sacrifice.

Captain America wouldn’t have been weak.

Captain America wouldn’t have been born defective.

Tony smiled.

“Funny? No. Predictable? Little bit. Loki wants drama. He wants an audience. He wants to prove something, which, as a professional attention-seeking narcissist, I can say is usually where the plan starts hemorrhaging structural integrity.”

Banner made a soft sound that might have been agreement.

Steve looked between them again, frustrated by a language he couldn’t quite access.

The argument turned, as arguments on SHIELD property tended to do, toward secrets.

Then weapons.

Then lies.

Then the cube.

Tony kept talking because talking kept him upright.

Talking kept everyone looking at his mouth instead of his hands,

his pulse,

the way his skin prickled every time Fury’s gaze cut across the room.

The files said SHIELD had been making weapons.

Of course they had.

Give a shadow organization a cosmic battery and the first thing they built was a bigger stick.

Humanity’s oldest engineering tradition.

Tony should have been angrier.

He was angry.

But beneath the anger sat something colder.

Recognition.

He knew what SHIELD did with power it didn’t understand.

It named it asset.

It named it threat.

It named it inhuman and opened it up to see how it worked.

Steve was saying something about accountability.

Fury was answering with necessity.

Natasha watched everyone like she was counting exits.

Banner had gone quiet again, the careful quiet of a man trying not to become the biggest problem in the room.

Tony hated that too.

So he pushed.

Because he was Tony Stark, and because every coping mechanism he had came with teeth.

The words sharpened.

Steve stepped closer.

Tony stood because sitting made him feel cornered and he refused to be cornered in a room full of SHIELD cameras.

The argument escalated exactly the way combustible material near Tony Stark tended to escalate: quickly, brightly, with excellent acoustics.

Steve’s eyes fixed on him.

“Yeah. Big man in a suit of armor. Take that off, what are you?”

For half a second, everything stopped.

Not outside.

Outside, the helicarrier still vibrated.

Screens still hummed.

Fury still watched.

Banner still breathed carefully beside the console.

Inside, Tony was eight years old again.

Howard’s voice, What are you?

Fury’s voice, Not human under current classification.

A doctor’s voice, Again.

The restraints had been leather at first.

Then metal, after he broke the leather.

Tony’s smile arrived before the rest of him did.

“Genius, billionaire, playboy, philanthropist.”

The line landed.

It always did.

Armor without metal.

Repulsor blast made of ego.

Inside, another answer uncurled.

More than you’d believe.

Worse than you’d forgive.

Something your government already cut open.

He did not say any of that.

Of course he didn’t.

Steve looked unimpressed.

“I know guys with none of that worth ten of you.”

Tony’s teeth clicked together.

Howard would have loved that.

Howard had loved Steve Rogers more than he had ever loved the son who had inherited his name and none of his acceptable mythology.

“I've seen the footage,” Steve continued. “The only thing you really fight for is yourself. You're not the guy to make the sacrifice play.”

Tony felt Banner look at him.

That made it worse.

He could take Steve’s judgment.

He had been built under judgment.

He could wear it, weaponize it, sell limited-edition sunglasses based on it.

But Banner looking at him with quiet curiosity, like he suspected the wound under the performance, made Tony want to peel out of his own skin.

“Everything special about you came out of a bottle,” Tony snapped.

A low blow.

Accurate, but low.

Steve moved.

Tony moved too.

For one bright, stupid second, the kinetic energy in Steve’s body sang to him.

A step.

Weight shift.

Muscle tension.

Potential impact.

Tony could take it.

If Steve hit him, Tony could absorb the force until the punch snapped back at the artifact.

He could stand there untouched while Captain America learned what Tony Stark was without the suit.

The thought flashed through him like hunger.

Then cameras.

Then Fury.

Then headlines.

Then cages.

Tony locked his mutation down so hard his bones ached.

Steve stopped inches away.

Banner’s voice cut in, strained.

“Guys.”

The scepter pulsed nearby, blue and ugly.

Tony glanced at it.

Right.

Alien mood lighting.

Probably not helping.

The argument splintered as alarms began to rise elsewhere on the ship.

Movement outside.

Voices.

The sense of something building under the floor.

But for one brief pocket of time, Steve stepped back.

Then he left.

The door closed behind him.

The lab exhaled.

Tony stared at the place Steve had been.

His pulse was too loud.

The room had too much motion.

Every vibration wanted in. He could feel the helicarrier’s engines, the footsteps in the hall, Banner’s shifting weight, the tiny kinetic tremor of his own fingers against the console.

He tucked his hands into his pockets.

“That's the guy my dad never shut up about?” Tony said, because if he did not speak, something honest might happen. “Wondering if they shouldn't have kept him on ice.”

Banner did not take the bait the way most people would have.

He just looked at the data, then at Tony.

“The guy's not wrong about Loki. He does have the jump on us.”

Tony latched onto the practical thread gratefully.

“What he's got is an ACME dynamite kit. It's gonna blow up in his face, and I'm gonna be there when it does.”

“And I'll read all about it.”

“Uh-huh. Or you'll be suiting up like the rest of us.”

Banner’s face shifted.

Not much.

Enough.

“Ah, see. I don't get a suit of armor. I'm exposed, like a nerve. It's a nightmare.”

Tony’s throat tightened.

There it was.

The sentence under all the others.

I am exposed.

I am vulnerable.

I am the danger.

Tony looked at him, really looked.

Bruce Banner stood under fluorescent lights in a government warship,

surrounded by people who feared what lived under his skin,

and said it like a fact.

Like the nightmare was not what had happened to him but what he was.

Tony knew that kind of math.

He hated it.

Slowly, carefully, he lifted one hand and touched the edge of the reactor through his shirt.

“You know, I've got a cluster of shrapnel, trying every second to crawl its way into my heart.”

He pointed at the mini-arc reactor in his chest.

“This stops it. This little circle of light. It's part of me now, not just armor. It's a... terrible privilege.”

Banner looked at the reactor.

Then at Tony.

“But you can control it.”

Tony held his gaze.

“Because I learned how.”

Not in a cave.

Not only in a cave.

Not only with the reactor. 

He's had to learn control over so much more. 

In labs.

In basements.

In a mansion in Westchester where a kind man in a wheelchair had taught him that power was not sin.

In a gymnasium reinforced for children who could crack concrete by accident.

In a dorm room where Rhodey had ordered vegetarian pizza and pretended not to notice Tony shaking.

He had learned.

He was still learning.

Every day he did not reach for the motion around him was a lesson.

Every impact he let hurt was a lesson.

Every camera he remembered before instinct could save him was a lesson.

Banner’s expression folded inward.

“It's different.”

Tony stepped closer to the console.

Banner tried to read the computer screen, but Tony slid the data aside with his finger so the two of them could see face-to-face.

“Hey, I've read all about your accident. That much gamma exposure should have killed you.”

Banner’s eyes flickered.

There. Not anger. Pain.

“So you're saying that the Hulk... the other guy... saved my life? That's nice. It's a nice sentiment. Saved it for what?”

Tony did not answer immediately.

For once, he let the silence exist.

He thought of Charles saying, You are not a mistake, Anthony.

He thought of Howard saying nothing at all.

He thought of Rhodey sitting on the floor beside him at two in the morning, close enough to stay, far enough not to trap.

He thought of Bruce Banner, exposed like a nerve, waiting for the world to decide whether his survival had been worth the cost.

Tony’s voice came out softer than he intended.

“I guess we'll find out.”

For a moment, neither of them moved.

Then Banner looked away first, returning to his computer like the data could save him from the conversation.

Maybe it could.

Tony let him.

They worked at their respective screens, side by side.

After a minute, Banner said,

“You might not like that.”

Tony’s mouth curved.

Not the press smile.

Not the weaponized one.
