**Request for someone_4u where the Avengers do some training and forget about their youngest teammate. Hope this is what you are looking for, I took some liberties in the plot! Omg it's so long, I am so sorry, I just fell in love with the idea once I got started. Enjoy!**

Tony straightened up, clapping his hands together. "Should be good to go now."

The team leaned in to the small room, looking around. It didn't seem too different, but who were they to judge Tony's handiwork.

"I outfitted it to push as much of Peter's powers as possible. Its got super-imposed lighting, so we get that hazy red, and I did it up with a randomization algorithm to test his spider-sense. We have illusion holograms, too, so he'll keep climbing around the room. There's a few other things in there, too, but I think I covered most of it."

Steve nodded his head. "We just want to see how he does in an hour, Stark. This is a baseline test to get an idea of what he's capable of."

Tony shrugged. "I don't really care what you all want to do. Ask him if you can run the tests, he says yes, you can use this room."

The team all waved the man off. They knew how to ask a literal child if they could run tests. As if sensing that he was a topic of discussion, Peter bounced down the hall, his eyes bright and searching. He'd only met the team a few weeks before, he was still a little star-struck by them.

"Hiya, Mr. Stark! Hi, team!"

Tony ruffled the teen's hair. "Hey, kiddo. I'm gonna work on some catch up work for Pep, you still good for training today?"

Peter nodded his head enthusiastically.

"Great. I'll be in my lab if you need me, I'm just going to be doing paperwork and boring reports and signing off on some projects."

Tony said his goodbyes, then headed down the hall and around the corner.

"So," Peter started excitedly. "What are we doing today?"

Natasha almost smiled at the boy's tone, Clint just barely catching the hint of her feelings on her face before she hid them again.

"Well, we're all going down to the big gym to spar and train with each other," Steve started. "We have something special for you, though. We don't really know a lot about your powers yet, so we set up a special room for you. It's designed to test your abilities and measure your bio-metrics. Think you can do that?"

Peter's smile faltered slightly. He thought he was going to get to train with the team, not on his own. After a split second, he smiled again.

"Sure! How long do you need me to do the test?"

Steve smiled back warmly. "Not long, maybe an hour?"

Peter nodded. "Okay."

The team headed downstairs to the gym and Peter wandered into the dark room. For a minute, nothing happened.

Then, out of no where, there was a barrage of bullets and harsh bursts of cold water, Peter's Spider Sense warning him just before they went off. The teen launched himself up into the air, then landed on nimble toes and fingers, dodging the projectiles and terrible shots of water.

Suddenly, the floor seemingly shifted and Peter panicked, thinking the floor might be giving out. He shot a web to a far corner, flinging himself to the wall and scrambling to the safety of the ceiling.

Just as he started to breath normally again, sharp spikes began to pop out from the ceiling, startling the boy and chasing him around the wall.

Another barrage of bullets.

Wet, soggy floors made Peter slip and fall.

Shifting walls.

Bullets.

Water.

Ceiling.

Spikes.

Bullets.

Water.

Bullets, spikes, shifting, walls, spikes, water, bullets, slipping floors.

Peter collapsed, his body giving out. He didn't know how long he'd been in the dark, hazy room, but he knew it was longer than a little bit. Longer than just a test.

The walls opened up again, Peter just barely rolling out of the way of a stream of cold, hard water before it splashed into the opposite wall.

The teen crawled to the door, banging for it to open and let him out. Begging FRIDAY. Begging for Tony.

His hands were worn raw, his arms weak with fatigue. His legs were wobbly, one of them dripping blood from a stray bullet, the other barely oozing from where one of the spikes had grazed him.

His torso was heaving, trying to soothe his lungs with full breaths, but there was only the dusty, warm, wet air in the room. The broken rib from when he'd fallen to the wet floors from wet hands ached against his muscles, the need for air outweighing the need for rest.

"Please! Just let me out!"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Tony came up to the penthouse, making himself a little late-afternoon snack. The rest of the team was there, too, each one collapsed in the living room with exhausted faces and bodies.

"Hey, how was training?"

"Good," Clint said. "Nat kicked our butts again."

The redhead smirked. "You just make it so easy!"

Tony laughed, then looked around more closely. "Did Peter go to take a shower or something?"

Everyone suddenly went rigid, as if preparing for some punishment.

"Shit," Sam whispered. Steve didn't even have it in him to scold the man, instead getting up and running to the elevator, Nat and Tony close behind him.

The AI sparked to life, saying that she'd let the teen out of the room just a few minutes ago, and that he was in the hall.

Tony nearly pried the doors of the elevator apart to get to the teen faster, his dress shoes slipping on the smooth flooring and sending him sprawling into the wall. He didn't even right himself as the elevator finally opened, instead half-crawling, half-galloping down the hall.

There, slumped against the wall of the hallway, was Peter, bloodied and tired and sore.

"Peter! Underoos, look at me!" Tony took the boy's head into his hands, examining the boy's wet curls and tired eyes. "Can you see me? Is anything blurry?"

"M's'r Stark?" Peter slurred slightly, his words punctuated by gasps and pants. "I asked for you."

Tony's heart broke as he heard that, glancing at his watch to take Peter's pulse. He'd been in that room for over 5 hours. He'd been hurt under Tony's care.

"I'm here now, okay, kid?" The billionaire scooped him up easily, letting the blood and water and sweat soak into his expensive suit. He started walking away, whispering sweet condolences and reassurances as he headed back towards the elevator, leaving Natasha and Steve behind, both shocked.

"5 hours," Steve whipered.

Natasha didn't say anything, just walked towards the stairs. She stalked up them, one at a time, her shoes barely making any noise as she got closer and closer to the penthouse. Steve wandered after her, still dazed by what he'd just seen.

"Come with me," she said when she got up there, her voice deadly calm. The team didn't dare disobey her.

"Is Peter okay?" Clint asked, siding up to Steve, Bucky not far behind.

Steve shook his head, not needing to say anymore.

The med-bay was hectic, but in the middle of that chaos, was Tony. He was sitting in a chair against the wall, head in his hands. The team approached him slowly, unsure of what he might say.

"Hey, Tones, is he-"

Tony held up a hand. "I trusted you people for one day! I trusted you again after everything, I trusted you with someone I care about, and you can't even keep an eye on him? You can't even go get him out of a literal torture chamber?"

Steve, feeling defensive, mumbled under his breath. "You programmed the room."

"You think I don't know that?" Tony roared, his voice breaking. Tears pooled in his eyes. "You don't think I'm turning my head over sideways wishing I had told you fucking people 'no'?"

No one said a thing for a long minute until Nat took a breath and sat next to her friend. "Is he going to be okay?"

Tony shrugged. "He's dazed and dehydrated. He has a gun shot wound, which will take a couple days, and the grazing on his leg isn't too deep. He has a broken rib, and a concussion. And I think he- uh, he might have had..."

Tony trailed off for a moment, eyes flitting around his palms.

"He might have had a panic attack in the room. It was the water. I thought..."

Everyone settled into horrified silence. What had they done?

"And the worst part?" Tony added, after a long few minutes. "It's that I know he won't blame any one of us. He'll say it's fine. I had FRIDAY pull up the video of him begging for someone to let him out, screaming for me, and he's going to say it's fine."

No one knew what to say to that, so they just said nothing and kept waiting in uncomfortable silence. Finally, after what felt like ages, a nurse came out of the room where Peter was.

"He's awake and stable and fine, just a little banged up. You guys can go in and see him."

Tony was the first to make it through the door, Nat pushing her way in next, Steve and the others following behind her.

"Hey, Bambi. How are you feeling?" Tony asked softly.

Peter shrugged. "I've been better, but I've also been so much worse." The teen looked around the room, taking in the downcast expressions and teary eyes. "Hey, what's up with all the sad faces? It's not like I died."

He smiled after he said that, flashing a bright face around the room.

"Really guys, it's fine. You got distracted, I get it. Trust me, I've been in some pretty awful fights, this was like... just me being so tired. I can always give it a second go if you want, too, now that I know what-"

Tony cut him off. "No, you're never taking another test ever again. And you're never training with these people ever again either."

Peter chuckled. "Whatever, Mister Stark, you're just a worried dad!"

Everyone blushed suddenly, feeling uncomfortable. Except Tony, who just shook his head, rolled his eyes, and sighed. "Whatever you say kid."

Peter smiled, then looked around again. Everyone was still looking so sad and guilty, so the teen reached out and grabbed the closest hand he could. Natasha.

"Really. I'm fine. It's not your fault."

The redhead smiled weakly, not even bothering to hold back tears anymore.

"Yeah?"

"Yeah."

Tony leaned over the bed, his eyebrows raised. "Told you so."
