Bruised But Not Broken - Irondad/spiderson

He has a heart

Tony Stark had survived invasions, gods, monsters, and his own worst instincts.

None of that prepared him for the sound of a teenager crying in his sleep.

He hadn't meant to hear it.

He was halfway down the hall, debating whether to leave entirely, when the sound slipped through the crack beneath Peter's door. It wasn't loud. It wasn't dramatic. It was broken in the way only people who didn't expect comfort ever sounded—short, choked breaths, like the body was trying not to wake itself up.

Like even unconscious, the kid was afraid of being a problem.

Tony stopped dead.

For a moment, instinct screamed at him to turn around. Give space. Respect boundaries. All the responsible adult things he was supposed to do.

Instead, his hand moved on its own.

He opened the door.

Peter was curled on his side, knees drawn too tight to his chest, arms wrapped around himself like he was holding something together by force. His face was turned into the pillow, muffling the sound, but Tony could see the way his shoulders shook with every breath.

He was dreaming.

Tony knew that look.

He'd worn it himself once. In caves. In nightmares that didn't care whether you were awake.

"Hey," Tony whispered automatically.

Peter didn't stir.

His fingers clenched in the sheets instead.

"No," Peter murmured, barely audible. "I'm sorry. I didn't mean to. I'm sorry."

The words hit Tony square in the chest.

He took a step closer, slow, careful, like approaching a wounded animal that might bolt if it sensed him. The floor didn't creak. The kid didn't wake.

"I'll fix it," Peter whispered. "I'll be better. I promise."

Tony swallowed hard.

Jesus.

This wasn't guilt. This wasn't teenage melodrama. This was a kid who genuinely believed his worth was tied to how little trouble he caused.

Tony sat down on the edge of the bed.

The mattress dipped, and Peter startled—breath hitching, heart rate spiking so fast Tony could hear it without trying.

"Hey, hey—Pete," Tony said quietly. "You're okay."

Peter bolted upright with a gasp, eyes wide and unfocused, chest heaving like he'd been drowning.

"No—no, I—" His hands flew up defensively before he even realized where he was. "I didn't—I'm sorry, I wasn't—"

"Peter," Tony said firmly, grounding his voice. "It's me."

The kid froze.

Blink.

Blink.

Recognition flickered, then horror.

"Oh god," Peter whispered. "I—did I—was I—"

Tony lifted his hands, palms out. "You were asleep. You didn't do anything wrong."

Peter stared at him like he didn't believe that sentence had ever been true in his life.

Slowly, his shoulders caved in on themselves.

"I'm sorry," he said again, smaller. "I didn't mean to make a scene."

That did it.

Something in Tony cracked—not loudly, not dramatically—but in the way tectonic plates shift before earthquakes.
