Ok, so it's been a little while since I wrote a deaging fic for the Avengers and thanks to the person who messaged me asking for it (I don't know is you want you name mentioned or not) But here's my Steve Rogers deaging fic. Please enjoy!

It had started with a headache. They'd returned from fighting near a factory and Steve had said he was going to sit down for a while. No one really worried about it, in fact most of them were worn out and feeling slightly irritated by the day's events. They had caught a group of mercenaries trying to raid a chemical plant and things had escalated to a larger fight and even to a small explosion. No one was happy and they had even been forced to have a chemical scrub down after being exposed to a leaked gas. The final verdict had been that the gas was harmless to them and the knowledge that the scrub down had been unnecessary had been even more annoying.

They had returned home and all split up. Tony had shut himself up in his lab, Clint had passed out on the couch and Steve had gone into his room to try and rid himself of a headache with a short nap. Soon after the others returned from their own mission in much the same mood.

The next morning was a slow one. A small mission was called but Clint and Natasha took care of it. Tony spent the day in his lab, sleeping part of it and working the rest. Bruce was busy with his own research and Thor was off for the day. No one saw Steve which was not such a surprise. Everyone was busy with their own affairs.

It wasn't until noon that a mission came through that required more people. Tony buzzed Steve's room repeatedly bot to no avail. No one was answering and finally he gave up and went searching for him. "Steve, come on man we've got a job to do." He called, throwing open the bedroom door.

There was a loud yelp from inside the room and Tony leaped backwards. Steve was not in his room, instead a boy had jerked upright from the bed and let out a shocked yell. "What the hell?" Tony squwaked loudly.

The boy lying on the bed was wearing one of Steve's shirts and was gazing at him with wide blue eyes. He couldn't have been more than seven or eight but she was terribly thin. Tony stared at him in disbelief, he wasn't stupid enough to believe Captain America could be up to no good, more like Steve was probably helping some kid but still he hadn't been expecting to find a child.

"Who are you?" The boy asked, eyes wide.

"More like who are you? You're in my house." Tony retorted, still a little stunned.

The boy looked around and suddenly seemed to realize he was not at home. "Where am I?" He asked, sounding afraid now.

"Stark Tower, where do you think?" The boy blinked stupidly, not comprehending. "I'm Tony Stark? Iron Man? Captain America brought you here didn't he? Big tall guy, blond hair? Excessively ripped?"

The boy shook his head, opened mouthed.

"Steve? Mr. Stars and Stripes?"

"I'm Steve." The boy said, plainly not understanding anything he said.

Tony groaned. "Alright Steve, I'm looking for the other Steve. This is his room. Did he bring you here?"

The boy's eyebrows came together. "I don't know. . ." He mumbled.

"You gotta speak up kid. Where'd he go?"

"There's no one here. I was at home. . . I was in bed. . ."

Tony groaned again. "Alright I'm just gonna send you home. What's your name? I'm gonna call your parents."

"We don't have a telephone." The boy said softly.

Tony groaned a third time. "cell phone then. What's your mom's name?"

"Sarah."

"Sarah what, it's kind of hard for me to find one Sarah in New York." Tony had already typed the name Sarah into his phone.

"Sarah Rogers." The boy was looking less worried and now a little taken aback by Tony's attitude and tone of voice.

Tony had finished typing before he realized what the kid had said. "Your name is Steve Rogers?"

The boy nodded, eyebrows shooting up.

"I don't think so. You're coming with me and you better start telling me the truth before I call the police." He stepped forward and hauled the boy out of the bed, slightly surprised by the child's light weight before leading him by the arm down the hall.

Bruce was in the living room, waiting to leave and looking impatient. "What's taking so long?" He asked.

Tony gave the boy a little push towards the couch and threw his hands up. "I don't know. I went to go get Steve and found this kid. He won't tell me his name or how to get ah old of his parents. I'm calling the police."

"I told you my name!" The boy cried, sounding upset.

"No, you told me Steve's name. I know Steve. You're not him. He's like four of you. Maybe five."

Bruce crossed his arms. "How did you get here?"

The boy looked at him for a moment before glancing at Tony. "I don't know, just let me out and I'll go home."

"We can't let a kid out on the streets of New York." Bruce said. "Can you give us your address."

The boy did and Tony typed it into his phone. A warehouse came up in it's location. "Kid. . ." He said, rubbing his forehead. "Ugh, JARVIS where's Steve?"

Captain Rogers is currently in the living room of the Tower Sir.

Tony made a face of aggravation. "JARVIS, could you scan yourself for system errors?"

I can sir but if this is related to the whereabouts of Captain Rogers I can assure you that he is in the living room.

"Yeah no I've got a kid here who keeps telling me he's Rogers."

Biometric scans confirm that that is Stephen Rogers. There are slight differences to his genetic makeup but all concluding data confirms that Captain Rogers is in the living room.

Bruce glanced at the boy who was now looking around wildly. "Who's talking?" He asked.

"That's not Steve." Tony argued, ignoring the kid.

"I wanna go home!" The boy said, now sounding overwhelmed. "Just let me go."

Bruce continued to study the boy before picking up his tablet from a side table. "JARVIS, could you please pull up a picture of Captain America prior to the super soldier serum.

Gladly Sir.

A moment later Bruce was squinting at the tablet. "Are there any earlier photos?"

According to the internet there is one senior high school photo and one photo of Captain Rogers as a child. I believe the photograph of Captain Rogers as a child would be most helpful.

"Can you pull it up?"

Ignoring the boy who was now looking around as though he was going insane Bruce handed the tablet to Tony. The boy in the picture was a few years younger and standing with a blond woman. She had her arm around his shoulders and he was leaning against her leg but faded and old there was no mistaking that it was the boy sitting on the couch.

Tony made a slight face. "No way. . ." He looked from the tablet to the boy and back before motion for Bruce to follow him out into the hall. "Stay here." He ordered the boy who had started to follow them.

"What the hell's going on?" He hissed, once they were out of ear shot.

"How should I know? Maybe something happened with the chemicals."

"Oh God. . ." Tony groaned and put his head in his hands. "We need to fix this. I can't deal with Captain tricycle."

Bruce made a small noise and nodded. "I'll take him down for a med eval. We've got to make sure nothing else is wrong with him. We should also figure out if the chemicals effected him and if they could effect anyone else."

"Alright. . . okay. . . I just spent the last ten minutes yelling at him that he wasn't Steve Rogers. How do I fix this?"

"Well you could just admit you're wrong. . ."

Tony gave him a sharp look, catching the jab. "I'm gonna call Thor and tell him to deal with the mission. You deal with the kid."

Bruce gave him a look of disbelief before rolling his eyes and stepping back into the livingroom. The boy was still sitting on the couch, looking around with narrowed eyes. A quick look over placed him at about eight or nine. Maybe ten but probably not but more than that he was terribly thin and terribly peaky looking.

"I'm sorry about all that. We were pretty confused about some stuff. Im Bruce." He squatted down and held out his hand to Steve. The boy took it with some trepidation and shook. "I'm a doctor too so I'm gonna ask you some questions. You can ask me questions too if you want."

Steve nodded and licked his lips. Bruce wondered if they would be able to pull up any old medical records. As he was now he looked so sickly and weak that he might as well try and help the kid until they were able to trun him back. "Can you tell me how old you are?"

"Eight. What's going on?"

Bruce took his wrist and pulse. "Well I'm not really sure." He said, counting in his head. "I'm gonna tell you you the truth. You're not supposed to be a kid. I know you as an adult and you were exposed to a chemical and whatever it was turned you back into a kid."

Steve stared at him blankly before making a face. "I don't think that can happen." He said doubtfully.

Bruce smiled a little. "I didn't either but I can prove it. Want to see a picture of yourself all grown up?"

The boy gave him another doubtful look but nodded and he pulled up picture of Steve from the army. He thought a black and white picture would probably be best. they would have to explain the world's new technology at some point but until then this would do and who knew, maybe by some stroke of luck they would get him cured or he would turn back on his own before it came to that.

"That can't be me!" The boy said, looking at the picture with a slightly miserable expression. "He's way too strong looking."

"Well that's a lot of years away. A lot changes."

The boy said nothing but Bruce had the distinct impression he did not believe it. "Listen, I know this is a lot to take in but I'm telling you the truth. More than that, this isn't even the 1940's. This is 2016."

The boy's eyes shot towards the door and he drew back slightly. "Listen mister, I just want to go home."

Bruce sighed and picked up a copy of that day's paper. "Look. See the date?" Steve was looking at him like he was a crazy person but his eyes focused on the date.

Steve took it and swallowed. "So I'm an old man?" He asked, sounding like he was coming out of his doubt.

"Not exactly. It's pretty complicated. I can tell you about it in a little bit but I think I'd like to examine you first. Will you come with me?"

Steve nodded and got to his feet, adjusting his shirt so it didn't fall off his shoulders. "Can I have something to wear?" He asked a little sheepishly.

Bruce grinned slightly. "Sure. Tony, can you send someone out to get him some clothes?" He called. A positive sounding yell came from the hallway and Bruce shrugged and lead Steve to the elevator. "It'll be just a little bit."

"So. . . if I'm an adult, do I live here?"

"No, you have your own place but you do have a room here. You woke up in it."

"I don't understand any of this!"

"It's alright. You will. Things will make more sense when I explain everything. You joined the army when you grew up and you were part of a program to make a super soldier. I can find a film on it if it helps."

He lead the boy out of the elevator and to his lab, telling him to sit on a table until he had found his doctor's bag.

"Who was talking earlier?" Steve asked, looking around. Bruce had the sudden thought that all of the things he was looking at were impressively new. He could not have seen anything like them before, in fact most people today couldn't have.

"A. . ." He wracked his brain for what to say. "It's called a computer. It's like a library inside of a box and run by electricity. This one can talk like a person."

"Is it magic?"

He laughed a little. It seemed so strange to think that Captain America believed in magic as a child. Maybe he did as an adult, Thor was enough to make people wonder. Bruce wasn't so convinced but who knew? "I guess you could say that but all man made. Like a car or a movie."

"I'd like to see one."

"We can look at one in a bit." He regretted saying box. No one had a box anymore. Well, no one friends with Tony Stark.

He checked the boy's heart and lungs, not pleased when he heard how shallow Steve's breathing was and his heart rhythm. "I'm going to give you a round of anti-biotics. That's a kind of medicine and an inhaler. It's for asthma. It'll help you breath." He went to a cabinet and fished for a bottle of anti-biotics. They hadn't had them in the 1920s. Then again, they hadn't has fluoridated water or most vaccines. He checked his cabinets and made a note to order an inhaler. "If you take this twice a day I think you'll start to feel better. Do you see the doctor much?"

"There's one who makes rounds in our neighborhood. He comes once a month and mom always tries to get me to see him but sometimes she has to call another one. I get sick a lot."

Bruce nodded. He had heard that. "Well I think you'll feel better once these kick in and the inhaler will help, I just have to get it for you."

"Am I sick as a grown up?"

"I've never seen you get sick. I'm not even sure you can."

A sort of whimsical smile passed over the boy's face and Bruce wasn't sure he believed him. "Why don't we go back upstairs. I can show you a computer. The boy nodded, looking a litle in over his head and Bruce lead him back to the elevator. He wasn't a history expert but he knew enough to know they had had elevators in the 1920s. He had already calculated that if Steve was eight then he would be from either the year 1926 or '27. He made plans to do a bit of reading later. Tony was probably already on that.

Once back upstairs Steve crept towards the window and looked out across the city. "I recognize a few buildings." He said, turning his head to look at Bruce.

Bruce for his part gave him a strained smile. "I told you it was New York."

"I can't believe I'm in the future." Steve said wistfully, leaving the window and taking a seat on the couch.

"I know this must be a lot to take in but the world's not so different." Bruce said, taking a seat next to him. "People still go to work and kids still play. People still go to the movies and baseball games."

"They do? Can people fly yet?"

Bruce laughed a little. "Well only in an airplane."

"What about underwater? Do we live underwater?"

"No. . . no one lives underwater."

"What about on the moon?"

Bruce laughed again. "Not there either. Mostly we just live on Earth. I'm from Ohio."

Steve nodded although he looked a little disappointed. "Bucky says we're gonna live on the moon in fifty years."

"Well, he might be off by a few but maybe some day."

Steve nodded again and sighed. "And I still live in New York?"

"You do. Here, if you have any questions about today we can look it up on the computer." He opened his lap top and waited.

Steve scrunched up his face. "Who's the president?"

"I can tell you that one. His name's Barack Obama." He pulled up a picture and Steve stared at it.

"I didn't know a colored man could be president. Good for him."

"Well he got elected twice." He decided not to comment on the 'colored' comment. In the 1920s that was polite and there would be time to correct that later.

Steve gave a serious nod and continued to look at the picture. "Is he a good president?"

"I think he's alright. Who's president in your time?"

"Calvin Coolidge. Can I see a picture of an elephant? Me and some boys went to the zoo last month and saw one."

Amused, Bruce pulled up the image and let Steve click through the different pictures. The boy learned fast and hit the arrow keys back and forth, smiling when he made the picture change. He told Bruce about the zoo and the different animals he had seen, occasionally asking to look at a new animal.

They were interrupted a few minutes later by Tony arriving with a shopping bag. "Pepper sent a lady out and got you some clothes." He said, handing Steve the bag.

After a quick look in the bag Steve got to his feet, using both arms to push himself up. "Where can I get dressed?" He asked.

Bruce directed him to an empty bedroom and told him it could be his if he wanted.

Once the boy was in the room he turned to Tony. "I need to order him an inhaler. I think he has asthma."

"Yeah I can get you one." Tony said. "What's he like?"

"Um. . . pretty normal. I told him the truth and I think believes me. He was asking about people flying so I guess he thinks it's the future.:

"Thor can fly."

"Thor's not exactly your average man."

Tony waved away his comment. "This is gonna be a pain." He said. "This place is about as un-1920s as you can get. I mean he said they didn't even have a phone."

Bruce gave him a raised eyebrow. "A lot of people didn't and Steve grew up poor."

"Yeah so he probably thinks electricity is witchcraft."

"I kinda doubt that."

"Fine but I seriously doubt we can explain everything to him."

"Well maybe we won't have to. Did you let the others know?"

"I sent everyone a message. Clint and Natasha should be back soon."

"Alright, well I'm going to take a blood sample from him and analyze it tonight so maybe I'll be able to find out what caused this. My money's still on the chemical plant."

"This better be reversible." Tony groaned.

So it's not really set at a specific time and I'll probably blend some elements from the comics kind of like I did in my Black Widow one and my Hawkeye one. The title comes from an episode of the Twilightzone. It doesn't really have anything to do with the story but I thought it sounded good. Thanks so much for reading. I'll try and update at least once a week and usually on Saturday.

I'm going to try and make stuff as historically accurate with this story as I can. It's actually kind of neat if Steve was bornJuly 4th 1918 he'd be the same age as by grandfather, less than a month apart (July 17th 1918). With some of the research I've been doing on the 20s it's kind of weird to think that the things I'm writing were things he experienced and saw change. Kind of cool too and I love history so I'll try and do my best with the history, I'm a US history major anyway so this is pretty fun for me.
