What the Hulk Kept

Summary:

After New York's alien invasion, Tony Stark is injured badly enough that even Stark Tower cannot pretend he is fine.

Bruce Banner stays to help with his recovery.

At first, it makes sense.

Then Bruce stops watching the monitors.

He starts watching Tony.

Chapter Text

Chapter 1

Tony woke up to the sound of someone moving too quietly outside his door.

Whoever it was had the careful, measured kind of silence people used when they thought silence was the same thing as not being noticed. The tower had too many systems for that. 

His eyes stayed closed.

The room smelled like clean sheets, antiseptic, and the faint metallic trace of burned wiring that had followed him home from the battle no matter how many filters JARVIS ran through the ventilation. Somewhere outside the glass, New York was still digging itself out of the sky.

Tony tried to breathe deeper.

His ribs immediately filed a complaint.

He stopped.

For a few seconds, that was all there was. Pain, thin and sharp under his sternum. A heavier ache across his shoulder. A bruise spreading hot and ugly along his back. His head felt stuffed with cotton, and his mouth tasted like he had spent the night licking the inside of a medical supply cabinet.

“JARVIS,” he said, or tried to.

It came out rough enough to embarrass him.

“Yes, sir.”

Tony let the familiar voice settle the edges of the room. Stark Tower. His bedroom. Not a hospital. Not SHIELD. Not some windowless debriefing suite where somebody with a badge could say observation like it was a kindness.

Good.

“How long?”

“You have been asleep for approximately twenty-one hours and forty-three minutes.”

Tony opened one eye.

The ceiling was still his ceiling. Expensive, understated, currently irritating. He shifted his left hand over the blanket. The IV tugged at the back of it.

“That’s excessive.”

“Your body disagreed.”

“My body is dramatic.”

“Your body survived an interdimensional invasion, a fall through a closing portal, multiple impacts, dehydration, and acute exhaustion.”

“See? Dramatic.”

The quiet outside the door stopped.

Tony turned his head too fast. The room smeared at the edges, and his stomach made a slow, unpleasant turn. He held still until the ceiling stopped trying to rotate.

“Sir,” JARVIS said.

“Don’t.”

“You have not yet been awake for one full minute.”

“And already criticized.”

“Observed.”

“Same family.”

The door opened before JARVIS could answer.

Pepper came in with a mug in one hand and a tablet under her arm. Her hair was pulled back in a way that said she had been handling calls, lawyers, press, and possibly the collapse of civilization before breakfast. There were shadows under her eyes she had not bothered to hide.

Tony looked at the mug first because looking at her face took more courage than he wanted to admit.

“Coffee?”

“No.”

“Then why bring it?”

“Because you need fluids.”

“You’re saying that like coffee isn’t a fluid.”

Pepper set the mug on the bedside table. “Electrolytes.”

“That is not a beverage. That is a threat.”

“You’re going to drink it.”

“That sounded very legally binding.”

“It can be.”

He tried to lift his hand toward the mug. His shoulder pulled. His ribs answered. The motion was small enough to be insulting, and still it made his breath shorten.

Pepper noticed.

Her hand came up, stopped before touching him, then lowered again. “Slowly.”

“I was going for dramatic effect.”

“You went gray.”

“That’s my post-invasion palette.”

She did not smile.

Tony looked away, annoyed at both of them.

“How bad?” he asked.

Pepper picked up the mug and placed it carefully in his reach. “Bad enough that you are not leaving this room today.”

“That’s not a medical diagnosis.”

“It’s an operational policy.”

“I’m being governed.”

“You’re being kept alive.”

“Hostile workplace.”

“Home workplace,” she corrected. “Which is worse, because I know where you keep all your access overrides.”

Tony took the mug because refusing would have required more energy than drinking. It tasted like citrus trying to pass a background check. He swallowed anyway.

Pepper watched the movement of his throat, the set of his mouth, the way he held the mug against the blanket with a hand that wanted to shake and was only barely being talked out of it.

“So,” he said, “how many things exploded while I was unconscious?”

“Several.”

“Any mine?”

“All of them are being reviewed by legal before I answer that.”

“Coward.”

“CEO.”

“Temporary.”

“Permanent if you keep trying to sit up.”

Tony’s attention went to the door again.

The quiet presence was still there.

Pepper followed his gaze, then looked back at him too quickly.

Tony narrowed his eyes. “Who’s outside?”

“No one you need to worry about.”

“That is never how that sentence works.”

“Tony.”

“Is it Fury?”

“No.”

“Worse than Fury?”

“That depends on your definition.”

“Pepper.”

She sighed once through her nose. “Dr. Banner.”

Tony blinked. “Banner?”

“Yes.”

“Here?”

“Yes.”

“In the tower?”

“Yes.”

“Voluntarily?”

Pepper’s expression shifted.

“As far as I know,” she said.

Tony looked back toward the door.

Bruce Banner had been in the tower yesterday. Or however many hours ago counted as yesterday after the sky opened and aliens poured through. Bruce had been in the lab before everything went to hell, then on the ground, then green, then not where Tony’s memory could reliably hold him. There were images after that, but they came in broken pieces: cold air, falling, someone shouting, something huge moving carefully where huge things had no right being careful.

He had assumed Bruce would leave once things settled. 

“He’s still here,” Tony said.

Pepper picked up the tablet and pretended to check something on it. “Yes.”

“For twenty-one hours?”

“He left the floor twice.”

“For?”

“Once to shower. Once because Steve threatened to sit on him until he ate something.”

Tony stared at her.

Pepper did not look up.

“That’s weird,” Tony said.

“Steve can be very persuasive.”

“I meant Banner.”

“I know.”

The hallway shifted.

Tony heard a low murmur, too quiet to make out. Another voice answered. Steve, probably. There was a pause. Then the doorframe filled with Bruce Banner looking like a man who had slept in a chair and lost the argument.

His hair was still damp at the edges, badly combed and already giving up. His shirt was wrinkled. He had a tablet tucked close against his ribs like a shield he was too polite to admit he was using. There was a faint scrape near his jaw and exhaustion around his eyes.

He stopped just inside the room.

“Morning,” Bruce said.

Tony looked at him for a beat. “You look terrible.”

Bruce blinked. Then his mouth moved, almost a smile. “Good to see you too.”

“It’s morning?”

“Technically.”

“Great. Technically morning. Technically alive. We’re doing great with technicalities.”

Pepper lifted the mug slightly. “Drink.”

Tony drank because Pepper had the look and Bruce had the tablet, and he had enough sense left to know when two quiet people were more dangerous than one loud one.

Bruce came farther in, but only to the foot of the bed. His gaze went to the monitors first, then to Tony’s face, then away before it could become staring.

“You’ve been running my vitals?” Tony asked.

“JARVIS has been running them,” Bruce said. “I’ve been looking at them.”

“For twenty-one hours?”

Bruce adjusted his grip on the tablet. “Not continuously.”

Pepper made a very small sound.

Tony looked at her.

She looked innocent in a way Pepper Potts had never been in her life.

“Define continuously,” Tony said.

Bruce’s eyes dipped to the tablet. “You had a few respiratory dips overnight.”

“That is not defining continuously.”

“No.”

“Banner.”

Bruce looked up.

“I wanted to make sure you were stable,” Bruce said.

Tony held the mug between both hands.

It was too warm against his palms. Or his hands were too cold.

“You could’ve asked JARVIS for updates from literally anywhere else.”

“Yes.”

“You stayed anyway.”

Bruce did not answer immediately.

“I stayed,” Bruce said.

Tony watched him.

It would have been easy to make a joke. 

“Huh,” Tony said instead.

Pepper’s eyes flicked to him.

Bruce seemed to brace for the follow-up.

Tony lifted the mug. “Well, that was a poor life choice. The tower breakfast options are terrible after an alien invasion.”

Bruce’s shoulders lowered by a fraction.

“Noted,” he said.

Pepper reached for the tablet at the end of the bed. “He also tried to leave bed at 3:12 this morning.”

Tony turned on her. “Betrayal.”

“You made it one foot.”

“I was doing reconnaissance.”

“You were trying to get to the workshop.”

“Same family.”

Bruce frowned. “You almost fell.”

Tony’s attention shifted back to him. “You saw that?”

“JARVIS alerted us.”

“Us.”

Bruce hesitated.

Pepper answered for him. “Me. Bruce. Steve.”

“Great,” Tony said. “A committee.”

“You were attached to an IV pole,” Pepper said.

“I was going to take it with me.”

“You were dragging it behind you.”

“That’s called teamwork.”

Bruce looked down at the tablet again, but Tony saw the faint change around his mouth. There and gone.

Then Tony tried to move his right leg, and pain climbed his side hard enough to take the air out of the ease.

He stopped breathing for half a second because breathing hurt.

Pepper stepped closer.

Bruce moved too.

Both of them stopped before touching him.

His hand hovered near the bedrail, fingers curled around nothing.

Tony pulled in air through his nose. Carefully. Annoyingly.

“I’m fine.”

“You’re not,” Pepper said.

“I’m functionally fine.”

“Also no.”

Bruce’s voice was quieter. “You don’t have to move yet.”

Tony looked at him.

He hated that not arguing was suddenly an option.

He settled back against the pillows in increments. By the time he was still, sweat had gathered at the back of his neck.

Pepper picked up a cloth from the bedside table and held it out.

Tony took it himself.

Small victories. Pathetic, but available.

Bruce watched the cloth change hands and then looked away.

“You always this good at bedside lurking?” Tony asked.

Bruce glanced back. “I don’t think that’s a medical term.”

“It is now. I’m naming it after you.”

“That seems unnecessary.”

“Science requires recognition.”

“Science asks for repeatable evidence.”

“Stay here another night and we’ll have a peer-reviewed sample.”

Pepper looked between them. “On that note, you need food.”

“No,” Tony said.

“Yes.”

“I have electrolytes.”

“That is not food.”

“It has emotional weight.”

“It has sodium.”

“Same family.”

A knock came against the open door, and Steve Rogers stepped in carrying a tray. He had a bandage near his temple and the irritating posture of a man who could be injured gracefully. The tray smelled like oatmeal, toast, and betrayal.

“I was told this required reinforcement,” Steve said.

Tony narrowed his eyes. “You brought oatmeal.”

“I brought breakfast.”

“That’s oatmeal.”

“There are berries.”

“Decorative lies.”

Steve set the tray on the rolling table, then hesitated before pushing it across the bed. He glanced at Pepper, then at Bruce, then back to Tony. “How are you feeling?”

“Oppressed.”

“Medically?”

“Medically oppressed.”

Steve nodded like he was taking that seriously. “Sounds serious.”

“I like him less when he adapts.”

Pepper moved the table into place. “Half.”

“Half of what?”

“The oatmeal.”

Tony looked at the bowl. “That’s an aggressive amount of oatmeal.”

“It’s a normal amount.”

“For who? Thor?”

Steve’s mouth twitched. Bruce gave up looking neutral and rubbed at his forehead.

Tony picked up the spoon with his IV hand, which was a mistake. The line tugged.

Pepper reached, stopped, and gave him a second.

Tony switched hands without comment.

Nobody commented either.

Good.

The oatmeal was as bad as expected.

He swallowed it anyway.

“Happy?”

“No,” Pepper said. “Continue.”

“You’re enjoying this.”

“I am not.”

“She is,” JARVIS said.

Pepper looked at the ceiling. “Not helpful.”

“I was asked to monitor morale.”

“No one asked you that,” Tony said.

“You implied it.”

“Your interpretation privileges are suspended.”

Bruce looked up at the ceiling. “Does that work?”

“No,” Pepper and JARVIS said together.

Tony pointed his spoon at Bruce. “Don’t encourage him. He’ll start making friends.”

Bruce’s face changed at that.

Steve cleared his throat. “Fury wants updates.”

Pepper’s expression flattened. “Fury can wait.”

“Is Fury asking,” Tony said, “or is SHIELD asking in that way where everybody pretends Fury didn’t ask?”

Steve pulled a folded paper from his back pocket and handed it to Pepper. “Medical status, incident reports, projected recovery timelines. For all Avengers personnel involved.”

Tony stopped eating.

Bruce’s gaze dropped to the tray.

Pepper read the first page, then the second. The set of her shoulders changed.

Tony knew that posture. Pepper facing down a room full of men who thought calm voices made overreach more polite.

“No,” she said.

Steve’s eyebrows lifted. “I told them that was likely.”

“Not likely,” Tony said. “Definite.”

Pepper flipped another page. “They want Bruce’s information too.”

Bruce became very still.

Tony set the spoon down.

Steve looked at Bruce first, then Tony.

“Absolutely not,” she said.

Bruce shifted. “They’re going to ask.”

“They asked,” Pepper said. “They received an answer.”

“They’ll keep asking.”

“Then they’ll keep receiving an answer.”

Tony leaned back against the pillows and regretted it immediately. His ribs hated confidence. “Banner, you’re not sending them anything.”

Bruce looked at him.

“What?” he said. “You thought I’d hand over your medical data with a bow?”

“I didn’t say that.”

“You were thinking something self-sacrificial and irritating.”

Bruce’s mouth tightened. “You don’t know what I was thinking.”

“Fair. But I’ve met you.”

Steve’s attention moved between them again. He did not interrupt.

Bruce looked at the tablet in his hand as if it might offer him a neutral place to put his eyes. “It may be easier if I cooperate.”

“For who?”

Bruce did not answer.

Tony picked up the spoon again, not because he wanted oatmeal but because Pepper was watching his hands and he needed something to do with them.

“For them?” Tony said. “Yes. For me? Bad. For you? Worse. For the part where somebody gets to make a file labeled giant green liability and pretend they understand anything? Catastrophic branding.”

Bruce’s lips parted and closed again.

Pepper set the SHIELD request on the side table, face down. “No medical files leave this tower without consent.”

Bruce looked uncomfortable with the word.

Steve folded his arms loosely. “They’ll argue public safety.”

“Of course they will,” Pepper said.

Tony snorted. It hurt. He kept going anyway. “Public safety is what people say when they want private access.”

“Tony,” Steve said, but not sharply.

“What? Too soon after saving the city to distrust the paperwork?”

Steve’s jaw worked once. “No.”

That answer was quieter than Tony expected.

Tony looked at him.

Bruce was still by the foot of the bed, one hand on the tablet, the other tucked close to his side. 

“Sit down,” Tony said.

Bruce looked up. “What?”

“You’re swaying.”

“I’m not.”

“You are,” Pepper said.

Bruce looked betrayed.

Steve brought the chair from near the window and set it close enough to be useful but not close enough to crowd the bed.

Tony ate another bite of oatmeal while waiting him out.

Bruce sat.

Pepper collected the SHIELD papers. “I need to call legal.”

“Use the angry voice,” Tony said.

“I have several.”

“The one that makes board members resign.”

Pepper’s mouth curved faintly. “Eat half.”

“Define half emotionally.”

“Physically.”

“Harsh.”

She touched the edge of the bed before leaving. Then she walked out with the papers and her phone already in her hand.

Steve stayed near the dresser.

Bruce stayed in the chair.

Tony ate because Pepper would return.

After three more bites, Tony set the spoon down. “You don’t have to do that.”

Bruce blinked. “Do what?”

“Look like the oatmeal is personally responsible for whether I live.”

Bruce glanced at the bowl. “You need food.”

“Everyone keeps saying that.”

“Because it keeps being true.”

“That was almost snippy.”

“Was it?”

“Little bit. I’m proud.”

Steve’s mouth twitched.

Bruce looked down, but this time the almost-smile stayed a second longer.

Tony could hear faint construction noise from far below, filtered through tower glass. New York fixing itself in pieces. His tower doing the same. People moving through damaged floors, checking systems, sealing what the battle had opened.

Bruce rubbed at his wrist. There was a reddish pressure mark there, half-hidden by his sleeve. Tony’s gaze caught on it before he made himself look away.

“So,” Tony said, aiming for lighter ground and landing somewhere uneven, “what’s your exit plan?”

Bruce looked over. “My what?”

“Exit plan. Don’t tell me you don’t have one. You have at least three. Probably color-coded. Possibly laminated.”

Steve’s attention sharpened, though he pretended it did not.

Bruce sat back a little. “I hadn’t decided.”

Tony stared at him.

“You hadn’t decided,” Tony repeated.

“No.”

“Whether to leave?”

Bruce glanced toward the windows. “Where to go.”

“Right,” he said.

Bruce’s fingers tightened once around the tablet, then eased. “I was going to wait until you were stable.”

“You said that like it’s a train schedule.”

Bruce’s eyes returned to him. “It’s practical.”

“Sure.”

“It is.”

“Okay.”

“It is,” Bruce repeated, quieter.

Steve looked down.

Tony pushed the oatmeal with the spoon. The berries bled a little color into the gray. “And after I’m stable?”

Bruce did not answer.

At the moment, his ribs hurt, his head was light, and his stamina had apparently been reduced to “survive breakfast conversation.”

He leaned back. The pillows did not help as much as they were paid to.

Bruce’s eyes flicked to the monitor.

Tony said, “Don’t.”

Bruce looked guilty.

“I didn’t say anything.”

“You were about to.”

“I was looking.”

“You were medically looming from a chair.”

“That’s different from bedside lurking?”

“Subtype.”

Bruce huffed a small laugh despite himself.

Tony looked away first.

JARVIS spoke into the room, softer than usual. “Sir, your pain medication interval will be available in six minutes.”

“Define available.”

“Recommended.”

“Define recommended.”

“Ms. Potts authorized me to use firm language.”

Tony scowled at the ceiling. “She’s weaponizing you.”

“Efficiently, sir.”

Steve shifted from the dresser. “I should check in downstairs.”

Tony gave him a look. “You mean you’re leaving me with the oatmeal council?”

“I mean Pepper asked me to make sure legal has what they need.”

“Traitor.”

“Recovery team,” Steve said.

“Everyone keeps making teams without me.”

Steve cleared his throat. “I’ll be back.”

“That sounded ominous.”

“It was meant to sound supportive.”

“Work on it.”

Steve left with a faint smile.

Tony and Bruce sat with the tray between them, the monitors at Tony’s side, the city beyond the windows.

Bruce looked toward the door once.

“You can go,” Tony said.

Bruce looked back.

Tony kept his voice casual. “I mean, if you’ve got somewhere. Gamma cave. Sad scientist motel. Secret swamp. I don’t know your brand.”

“I know I can go.”

“That’s not what I asked.”

“No,” Bruce said. “I don’t have somewhere I need to be right now.”

Tony held still.

Bruce stayed in the chair.

Tony picked up the spoon again and took another bite of oatmeal that had gone lukewarm at the edges.

“Terrible hospitality,” he said after swallowing.

Bruce looked at him carefully.

Tony gestured with the spoon. “You stay in a billionaire’s tower after saving the world, and this is what they serve you. Oatmeal. Electrolytes. Legal threats.”

“I’ve stayed in worse places.”

“I believe that, and I’m choosing not to unpack it before breakfast.”

“Probably wise.”

“Smartest man in the room.”

Bruce’s mouth twitched. “I think that’s still you.”

“Obviously. I meant morally.”

That surprised the laugh out of him.

The monitor kept its steady rhythm.

Bruce looked down at the tablet again, but his shoulders were looser than they had been when he entered.

Tony ate another bite. Then another, because if Pepper came back and saw measurable progress, she might delay the next lecture by at least thirty seconds.

He did not ask again.
