Fulfilled Fate

Summary:

Some futures are chosen.

Others arrive uninvited.

As Harry and Tony finally find the peace they've earned, an impossible visitor reminds them that saving the world is never finished.

Chapter Text

Tony sat on the edge of the clinical‑white sofa in the primary suite, his frame looking skeletal beneath a borrowed t‑shirt. He looked like a prototype that had been run through a stress test and left for scrap.

Harry stood by the glass wall, his back to the churning ocean. He hadn’t moved since they’d arrived home. His green eyes were vivid, sharp with protective intensity and an undercurrent of dry fury.

Tony swallowed, then said quietly, “I’m sorry I lost the compass you gave me.”

Harry turned, the shift immediate. “How?”

Tony opened his mouth—then froze. His pupils constricted. His breath hitched. The room fell away.

Harry stepped closer. “Tony. How did you lose it?”

Tony’s chest stuttered once, twice. Then the flashback hit.

The desert sun was a white blade overhead. The humvee rattled hard enough to shake teeth loose. Tony sat wedged between two soldiers, trying to pretend the vibration wasn’t crawling up his spine. His fingers kept brushing the compass in his pocket—Harry’s compass—like a talisman.

The first explosion was a concussive punch to the side of the humvee. The world snapped sideways. Screaming metal. Sand. Shouts. The vehicle rolled, throwing Tony against the door, then the ceiling, then the floor. His ears rang so loudly he couldn’t hear his own breath.

One moment he was in the vehicle watching the soldiers get slaughtered, and then he was out, crouched beside the vehicle taking fire. 

Tony’s hand flew to his pocket—instinct, terror—and he felt the compass under his fingers. He yanked it out, clutching it so hard the metal bit into his palm.

Another explosion. Closer.

He looked over.

A missile, its casing gleaming in the sun.

STARK INDUSTRIES.

His name. His legacy. His signature.

The last thing he saw before the blast hit was the compass flying out of his hand as the world went white.

Tony jerked back into the present with a sharp inhale, shoulders locked, eyes unfocused. His breath came too fast, too shallow.

Harry was already kneeling in front of him, voice low and steady. “Tony. Look at me.”

Tony’s gaze flicked, unfixed.

“Good,” Harry said. “You’re here. You’re not in the desert. Put your feet flat on the floor.”

Tony obeyed automatically, muscles trembling.

“Now breathe with me. In for four.” Harry counted, slow and even. “Hold for two. Out for six.”

Tony tried. His breath stuttered, caught, then broke.

Harry tightened his grip on Tony’s wrist, thumb over the pulse point. “You’re safe. You’re home. I’ve got you. Again—four in.”

Tony inhaled, shaky but following.

“Hold. Two. Out. Six.”

The exhale came out like a collapse, but it came.

Harry stayed with him, guiding each breath until Tony’s shoulders finally dropped and the tremor in his left arm eased.

Tony pressed a hand over his eyes. “I saw the missile. My name on it. I lost the compass when the blast hit. I’m sorry, Harry. I didn’t mean to—”

Harry shook his head once. “You don’t apologize for surviving.”

Tony let out a thin, exhausted breath. “Yinsen died so I could get the suit online. He saved me, and I watched him bleed out on a pile of Stark Industries crates. My crates. My weapons. My life’s work was the last thing he saw before the light went out.”

Tony’s breath hitched, a shallow, fast intake of air that suggested he was still falling. Harry didn't say a word. He leaned forward and pulled Tony into a tight, grounding hug, burying his face in the crook of Tony’s neck. They stayed like that for a long time, two halves of a circuit finally stable, as the silence of the last thirteen years was replaced by the rhythmic hammering of Tony’s heart against the metal casing.

Later, Harry insisted on "checking the integration." He had brought a small kit of what looked like advanced medical scanners from the Signal Yard, but Tony knew the vibration. He felt the faint, electric tingle of magic as Harry’s hands moved over his chest and arms. It felt like a low-voltage current running beneath his skin, knitting the molecular bonds back together, soothing the raw, angry tissue around the reactor housing.

"No more, Anthony," Harry said, his voice dropping into that sincere register as he finished. "No more reckless demonstrations. No more disappearing into conflict zones without a security detail that actually knows how to lead a convoy."

"I didn't choose to be kidnapped, Harry," Tony countered, his sarcasm returning as his strength did. "I was a passenger. Targeted strike. Kinetic discharge."

"You chose to be careless," Harry argued, his green eyes bright behind his rectangular glasses. "You decided to believe the world was as predictable as one of your equations. You knew the risks of the Kunar Province, and you treated it like a day at the track. You have a soulmate, Tony. We have a godson who asks about you every day. You are not alone anymore."

They worked through it in the dark, the argument shifting from responsibility to guilt and back again. Tony admitted, in a voice barely above a whisper, that there were nights in the cave where he believed he’d never see Harry again. Harry admitted he would have torn the Statute of Secrecy to shreds and Apparated directly into the mountains if he’d been able to find the coordinates.


Monday: April 21, 2008

The following Monday, the executive floor of Stark Industries was a battlefield. Tony’s announcement that SI would cease weapons manufacturing had hit the Board like a kinetic discharge. The conference room felt over-oxygenated, tense, and brittle.

Tony and Pepper were still inside with the directors, fielding questions that sounded more like cross‑examination than corporate governance. Harry stayed in the hallway, leaning against the wall opposite the frosted glass doors, watching the flow of staff.

Obadiah’s assistant—Marcy—approached with a tablet hugged to her chest. She wasn’t flustered, but she wasn’t calm either. Her eyes flicked toward the conference room, then toward the executive elevators. She hesitated when she saw Harry.

“Busy morning,” she said lightly.

Harry nodded. “Seems to be.”

She shifted the tablet, almost shielding the screen. “Lots of…movement. Everyone’s adjusting.”

It wasn’t what she said. It was the way she said it—careful, measured, as if she were stepping around something sharp. Her gaze darted again toward the elevators, then she excused herself and walked away too quickly for someone supposedly unbothered.

Harry watched her go, a faint prickle running down his spine.

Pepper guided Tony out with a hand at his elbow, her expression composed but tight. Harry fell into step behind them, watching the room, watching the people who avoided looking at Tony, watching the ones who looked too long.

They didn’t stop in the hallway. Pepper steered them toward Tony’s office—her office, really. She used it more than he did. The space was clean and efficient, with everything in labeled folders and color‑coded trays. The only sign it belonged to Tony Stark was the abstract sculpture in the corner: a twisting piece of brushed steel that looked like a Möbius strip caught mid‑argument.

Pepper shut the door behind them.

Tony dropped into the chair, the reactor humming faintly. “That was brutal.”

Pepper didn’t disagree. She set her tablet down with precision. “They’re scared. Stockholders are calling every five minutes.”

Harry remained standing, hands in his pockets. “I spoke with Marcy before the meeting.”

Pepper looked up. “Marcy?”

“Obadiah’s assistant,” Harry said. “She didn’t say anything specific, but she’s unsettled. Not about the board. About…movement. Executive‑level movement.”

Tony frowned. “Movement... meaning what?”

“Not sure yet,” Harry said. “But she was careful. Too careful. She kept glancing toward the executive elevators like she expected someone to appear.”

Pepper’s posture shifted—subtle, but sharp. “I can pull departmental routing and access logs. Quietly.”

Harry nodded. “Good. Nothing that triggers alerts. Just patterns.”

Tony rubbed his forehead. “Do I need to talk to Obie?”

“No,” Harry said, firm. “Not now. You’re still recovering, and you’ve just detonated the company’s business model. Let Pepper look into whatever’s shifting. I’ll start checking from my side—personnel changes, inventory flow, anything that doesn’t match the usual rhythm.”

Pepper added, “You focus on getting healthier. That’s the priority.”

Tony let out a slow breath. “So you two investigate, and I…eat vegetables and don’t die.”

Harry’s mouth twitched. “Precisely.”

Pepper gathered her tablet. “We’ll keep this quiet. If there’s nothing to worry about, we’ll know quickly. If there is…we’ll handle it.”

Tony didn’t argue. He just leaned back, exhausted, letting the two of them take the weight he couldn’t carry yet.

The recovery period was a blur of work and silence. By mid-June, Tony was still physically weak, his emaciated frame requiring the nutrient-dense blends Harry prepared, but his mind was moving at a relentless pace. He spent eighteen hours a day in the workshop, his attention funneled into two primary objectives: refining the arc reactor and designing the Mark II.

The workshop was no longer just an engineering lab; it was a sanctuary. Harry had quietly reinforced the structure, weaving stabilization runes into the white concrete foundations and the structural steel discs.

"It’s structural enrichment, Tony. Ergonomics for the house," Harry would say when Tony asked.

"Right. Ergonomics. Very prestigious," Tony would tease, though he spent hours trying to understand the science of Harry's magic. He’d set up oscilloscopes to monitor the ambient field, trying to find the math behind the way Harry could fix a broken glass without touching it.

The bots were in their element. DUM-E had taken on the role of primary safety monitor, his sensor light pulsing a steady amber as he hovered near Tony’s shoulder. Whenever Tony’s heart rate spiked or his breathing became shallow, DUM-E would nudge his elbow with a fire extinguisher nozzle.

"Not now, DUM-E! I’m not on fire. I’m calibrating!" Tony would shout.

U was stationed at the secondary bench, systematically sorting the high-grade titanium plates for the suit’s frame, while Butterfingers handled the delicate micro-circuitry for the flight control system. The robot’s movements were glacial and cautious, its pressure sensors agonizing over the grip.

"Bring it here, you useless heap of scrap," Tony muttered, though he patted U’s base as he moved past.

The Mark II was taking shape; it was a masterpiece of aerospace technology—sleek, silver, and stripped of everything except propulsion and flight controls. Tony had built the frame from a high-grade titanium-gold alloy, the same materials he’d used for the Atacama rover.

"Okay, let's do this," Tony said, stepping into the center of the fabrication floor. He was wearing the preliminary flight boots and gauntlets, the metallic clack of the hardware echoing in the disc-shaped room.

Harry sat on a nearby drafting table, his legs dangling, holding his titanium fountain pen. "JARVIS, record everything. If he accidentally Apparates himself into the ceiling, I want the thermal data."

"I have already prepared the high-speed cameras, Sir," JARVIS noted.

Tony looked at Harry, his brown eyes observant and uncharacteristically still. "Sometimes you gotta run before you can walk, H. It’s a law."

"It’s a slogan for a shoe company, Tony. It’s not physics," Harry countered, but he didn't pull back his sleeve.

"Launch in three... two... one."

The repulsors ignited with a resonant, joyous hum. Tony lifted off the floor, the displacement of mass creating a localized distortion in the air. He hovered for a beat, his grin wide and genuine, before banking toward the open ocean side of the workshop.

"JARVIS, take me up! Max thrust!"

Tony roared out over the Pacific, a silver streak against the blue California sky. Harry stood on the testing platform, tracking the high-velocity signature. He felt a surge of pride, a grounding warmth that had nothing to do with magic. Tony was flying. He wasn't just surviving; he was conquering the variables.

"Altitude is four thousand feet... five thousand," JARVIS reported through the workshop speakers. "Sir, I must advise you that the icing problem at this altitude is becoming statistically significant."

"Just a little higher, JARVIS! Let's see what this thing can—"

Suddenly, the signal from the gauntlets flickered. On the monitors, the thermal readings dropped into the blue.

"Ice! Total system failure!" Tony’s voice crackled over the comms, sounding more precise than frightened.

"Tony! Level out!"

"He is in a free-fall, Mr. Potter," JARVIS said, the British lilt carrying a note of profound concern. "Primary thrusters are locked. I am attempting to reboot the flight control subroutine."

Harry gripped his wand, his fingers finding the mechanical mark on his elbow. He focused every ounce of his intent on the silver shape plummeting toward the cliffs. He didn't want to Apparate into the sky—the atmospheric pressure would kill him—but he could anchor the descent.

"Tony! Deploy the flaps! Use the manual override!" Harry shouted.

"I’m working... on it... H!"

The suit’s stabilizers flared for a split second, catching the air. Tony banked hard, the silver armor screeching as it fought gravity. He wasn't falling anymore; he was a high-velocity projectile aimed straight at the mansion.

"Sir, your trajectory is—"

CRASH.

The sound was a textbook displacement of mass. Tony slammed through the roof of the living room, the glass curtain walls vibrating as the silver armor punched through the white concrete discs. He tumbled onto the floor, a tangle of metal and dust, coming to a stop three feet from the sunken seating area.

Harry was there in a second, sprinting from the workshop elevator. He knelt beside the suit, his hands blurring as he worked the mechanical locks. "Tony? Tony! Answer me!"

The faceplate clicked open. Tony looked up at him, his face soot-stained but his eyes wide and hungry for more data. He let out a short, jagged laugh.

"Note to self," Tony wheezed, his lungs dragging in the air. "The icing problem is... not a rounding error. And we definitely need a better roof."

Harry stared at him, the fury and the relief clashing in his chest until he finally let out a tired, genuine chuckle. He reached out and gripped Tony’s head, leaning in and giving Tony a kiss.

"You're an ass, Anthony," Harry whispered.

"Yet, you're still here, H," Tony replied.

The silence of the room returned, but it wasn't the silence of the cave. It was the silence of a system that had survived its first major failure and was already planning the next breakthrough. The Mark III was waiting, and for the first time in his life, Tony Stark knew exactly where home was.
