(AN: This was based one two prompts the first being Tony saying "You better be sick or dying in there" to Peter and then finding out its true. And the second being Peter suffers from a permanent injury. So, thank you to those that sent those in and thank you to everyone that sent an encouragement to my inbox on tumblr to help me write you guys are the reason this was written at all so, I love you. And I really hope you enjoy)

Tony banged his fist on Peters door, quickly losing his patience. "Will you hurry up? How long does it take to get out of your suit? God, you better be sick or dying in there with all the time you're taking."

The mechanic grunted, annoyed and looked at his watch again. He'd been waiting for ten minutes for Peter to get out of his spider-suit so he could fix it. Sometime during the mission, the sensors had been compromised and stopped sending out information.

"Come on, kid. I have other stuff to do tonight. I can't wait around for you."

"Is Peter in there alone?" Tony turned at Steve's worried voice and waved a hand.

"Yes, because I may be a helicopter parent for a kid I'm not even remotely related to but I am not going to watch him get dressed, thank you."

Steve pushed past him, to the door, voice hitching up a notch in tone and concern. "Tony, this is serious. He should be in the med bay!"

Natasha and Sam turned at the captains raised voice, looking just as worried and Tony started to panic a little bit. "What? Why?"

Natasha frowned, looking at Sam incredulously. "Because he hit his head. Really hard. Tony, he was out for a full two minutes mid-mission. He hit the ground so hard I thought his skull was going to crack open like an egg. I'm surprised he even woke up let alone swung back here."

Sam shook his head, confused. "Didn't Karen or Friday alert you?"

Tony's heart was about to explode in his chest. Peter had been hurt and he hadn't known? "No! His suits sensors were damaged! I haven't gotten any information from his suit for the last thirty minutes!"

Steve thumped on the door, calling out to the youngest avenger. "Peter, I need you to answer me. Are you okay?"

A muffled voice came through, slightly slurred and very tired. "Yes, please stop yelling. I'm fine I just can't move that fast because of this stupid headache. It's killing m-"

Tony's stomach clenched into a knot at the sudden cut off of Peters' voice because he hadn't trailed off, no his word had been strangled before a groan and crash sounded from the other side of the door.

Steve jumped in fright at the crash and Tony's stomach curled tighter at the heavy thump of something hitting the carpet. Something like Peter.

"Peter, I'm coming in!"

Steve shoved the door open as all four heroes rushed in, only to freeze in the doorway at the sight greeting them.

Peter was on the floor, back rigid, eyes rolled back into his head as his whole body shook.

Steve reacted first, sprinting forward and calling out. "He's having a seizure! Someone call Bruce!"

He ran in and dropped onto his knees beside the kid, hastily turning Peter on his side and slipping a protective hand under his head.

Tony blinked after a second and collected himself, making his way to the two on the ground. "Friday, get Bruce in here!"

"Yes, Boss." The AI's voice was almost drowned out entirely by the noises the teenager was making. He grunted as he shook, limbs smacking the floor as Steve protected his head and his breaths sounded so strangled that Tony was worried he'd asphyxiate.

His own voice came shakily as he watched Peter seize, unable to do anything but wait for it to be over. "What's happening to him?"

Steve's worried eyes met with Natasha's and Sam's from where they stood in the doorway. "It's gotta be the head injury. It must be worse than we thought. Dammit, I knew I should have stayed with him."

Tony didn't bother dignifying that with a response since everyone knew Cap, and half the team of heroes had been too preoccupied with the mission to worry about babysitting a kid that should have known better.

Sam was looking down at his watch, counting the seconds that ticked by as the crease between his eyebrows grew deeper because, with his enhanced healing, a seizure for Peter should only last a couple of minutes before it got really dangerous.

Tony couldn't concentrate on anything but the sharp pangs of worry stabbing through his chest with every beat of his heart because he didn't know what to do. There was nothing to do.

He could only sit there and watch the fifteen-year-old shake and grunt, barely bringing in enough air between his clenched teeth. He didn't even know what was happening and Tony had never liked being in the dark. Peters' head thumped harder against Steve's hand and Tony felt his throat begin to squeeze tight.

Footsteps came thundering down the hallway, coming closer and growing louder until finally, Bruce was pulling up to the doorway, pushing a gurney with him.

"How long has he been seizing for?"

Sam looked up from his watch, eyebrows pinched. "Just over a minute."

Bruce nodded and pulled his bag off the gurney before kneeling next to his patient. "What happened?"

Steve answered that one, voice slightly strained from holding the shaking teenager on his side. He may have been having a seizure but he still had super strength and he was hard to hold on to.

"He was hit in the head during the mission and was down for a couple minutes but when he was up he was mostly okay."

Bruce snapped his gloves on and pulled a needle out of his bag. "What does 'mostly okay' mean?"

Natasha spoke up from the doorway, voice more strained than Tony had ever heard it. "He said he had a bad headache and his words were slurred."

Tony shuffled back a little, allowing Bruce access to Peters' arm to inject the anticonvulsant.

It took a moment, but Peter's shaking started to die down, his eyes closing where they had been rolled back. But the seizure didn't stop completely. Peter's muscles were still locked tight, his jaw clenched too and Tony could see the fine tremors vibrating through him.

"Why isn't it stopping?" The anticonvulsant had eased it a little, allowing Peter to breathe at a safer rate, but the seizure was still going and Bruce sighed.

"Dammit."

"What? What does that mean?" Tony knew he was heading for a kind of panic he couldn't calm down from and he consciously eased his breaths and tried to slow them down.

"It means he needs a head scan. Natasha, grab the backboard. Sam, get over here."

Both heroes did as they were told, hurrying over and crouching next to Bruce as he began giving orders.

"Put the backboard right up against his back, we're going to roll him on three. Ready? One, two, three. Natasha, get those orange belts there."

Peter grunted, limbs still trembling as the hands on him pulled and pushed and strapped him down. His vision was blurry and while he could hear everything around him, his mind was having trouble processing what it all meant.

Whatever he was lying on was hard and his shoulder blades knocked against it as he shook, muscles tense and locked tight.

Bruce's familiar voice came close to his ear as a strong hand pushed his left arm down and strapped it tight while his other arm was released as a blood pressure cuff was wrapped around it. Peter didn't know what was happening and he was scared.

Tony watched in horror as the teenager was tied down. "I thought you weren't supposed to hold people down when they had seizures?"

Bruce grunted with effort as he tore Peters shirt open and pressed monitors to his chest. "Normally you wouldn't but we need him in the med bay now and he'd roll right off if he weren't secured. Dammit, Sam how long has it been?"

The man looked down at his watch, frowning. "Over two minutes, now."

Bruce cursed and mumbled something else but Tony wasn't listening because Peter was looking at him. While he seized, hands clenched into tight fists, neck straining while his head thumped back against the backboard, he stared up at Tony. His eyes were wide and frightened with tears that leaked out the corners to roll down his temples and into his hair.

Tony leaned forward, voice hollow. "Peter, can you hear me?"

And to his horror, Peter nodded. He was still shaking, still going through the seizure but he was conscious and aware and Tony almost wished he weren't because then Peter wouldn't have to be so scared.

Tony quickly grabbed the teenagers hand in his, squeezing it gently as he called out for help. "Bruce, he's awake."

The doctors head snapped up from where he was connecting lines and monitors. "What? Is he responding?"

Tony nodded and kept his eyes on the kids, trying not to show how panicked he was. "Yes, what do I do?"

Bruce shook his head a little as if trying to focus, and his hands hurried back to his task. "Talk to him, try and keep him calm."

Bruce went back to instructing the others while Tony leaned over Peter and tried for a smile. "Hey, buddy. You're okay. Bruce is taking care of you and I'm going to keep holding your hand. Just keep looking at me. Everything's going to be fine."

Bruce spoke up, voice controlled and calm, making Tony feel a little more at ease. "Peter, we're going to lift you into the gurney and get you into the med bay. Just try to keep breathing."

Peter blinked up at Tony, unable to squeeze the fingers holding his as he felt the backboard and himself being lifted and moved onto the gurney. His jaw was clenched tight and he couldn't speak, trapped in his own body.

He wanted to say something, to ask what was happening to him or tell Tony he was sorry for not telling him about hitting his head. But all that came from his mouth was a moan. Tony leaned over him as the others began pulling Peters gurney down the hall.

"Just hang on, kid. You'll be okay." He was slightly out of breath as they raced to the med bay and he lifted a careful hand to brush Peters tears away with his thumb.

Peter wanted to believe him, he wanted to be okay, but his head hurt so badly and it was getting harder to focus.

Peter watched Tony's worried eyes and tried to hold onto them but they flickered away when something started beeping.

Bruce lifted his tablet as he ran alongside Peter gurney, cursing. "Shit. Move faster! He's going to-"

Peter's eyes rolled back and his back arched, chest straining against the straps holding him down. His heart raced in his chest and he could hear Tony yelling something, hand tightening on his.

And then there was nothing but white.

(Theres more coming! I hope you like it! The next chapter jumps straight from here to a few weeks later so theres no waiting around while hes in the coma its just right to the damage and consequences of the TBI.
