Chapter 1

Rosie Marie Virginia Stark isn't your average teenager. By the age of 14 she's already experienced more than most people will in their whole lives. She has her crazy family to thank for that. The Avengers. Her crazy, messed up, amazing family that she wouldn't swap for the world. That's why she finds herself flying in a helicopter towards a base with the world's most dangerous assassins in front of her.

"GO!" Clint Barton aka Hawkeye screamed to Natasha Romanoff aka Black Widow and Rosie aka Iron Woman and (without the suit) Death Adder. Long story short she's killed people with snakes more times then she can count. When A.I.M decide to experiments on snakes it's kind of easy to kill the Agents with them. Oh and she's also fought a genetically engineered Boa Constrictor. That is one experience she never wants to repeat.

Natasha was the first one to jump out the helicopter with Rosie following straight after. Rosie ducked as the blades of the helicopter swung round furiously above her. Nearly as soon as they'd hit the ground bullets were fired at them from the compound. Looking up slightly she saw Natasha firing at the men surrounding the compound. Taking out her gun she quickly did the same and not long after arrows flew over her head each time finding their mark. Rosie dived to avoid bullets that were aimed at her head with ease. Jumping back on her feet she took out her Katanas off her back and started to run towards the door with Widow and Hawkeye on either side of her. All Rosie new about this mission was they needed to get a computer hard drive and get out without being killed. What was on it, they weren't told and she hated it. This was the second S.H.I.E.L.D. mission Rosie had gone on with Natasha and Clint, Budapest being her first.

"Adder this way!" Clint hissed as they ran into the compound when all the men outside were either dead or unconscious. Rosie looked up to see Clint and Natasha sprinting off down the hall to the right. Seeing this she quickly turned and hit the man coming through the door after them with the butt of her Katana before putting her Katanas back in their holds on her back and running after them. Not long after she caught up with them. Clint seeing her shoved her in front of him and behind Natasha. Rosie rolled her eyes at his actions. He's always trying to protect both Natasha and Rosie in the field even though they don't need it (well Natasha defiantly, Rosie sometimes she does).

"So where is this hard drive?" Rosie shouted to them.

"Don't know," Clint shrugged, "Just follow Nat."

"Well that was very useful, thank you!" Rosie rolled her eyes, maybe Natasha knows, "Tasha, please say you know where we're going!"

"I have an idea," Natasha smirked. Rosie's eyes widened. Great, if neither of them know then they're in trouble.

"How you two are still alive I'll never know," Rosie muttered under her breath. Neither of them seemed to ever have a plan so how they survive in the field is beyond her. Then mind you Rosie rarely ever has a plan and she's still alive, at the moment.

"Heard that!" Clint smirked.

"Whatever," Rosie laughed.

"Will you two shut up?" Natasha hissed.

"Well someone's grumpy," Clint whispered to Rosie. Natasha looked over her shoulder and glared at Clint and Rosie who was holding back a laugh. Rolling her eyes Natasha pushed open a door on the right before walking into an office.

"Watch the door," she ordered Rosie as soon as the three were inside. Rosie nodded before taking a gun out of its holster on her leg and looking out the door. Behind her she could hear Natasha and Clint arguing about something that she didn't want to know about. For what she managed to pick up from the argument it sounded like they were fighting about the best way to get out. So they don't even have an escape route! Well this is going from better to worse!

"Guys hurry up!" Rosie hissed. If they don't have an escape route they're going to need as much time as they can get to find one. The men would be coming after them and they'd soon be in this corridor.

"Got it, let's go," Natasha told them not long after. Rosie nodded and ran out the door. She just went to look behind her when she was pushed into another room. Rosie crashed through the open door and skidded along the ground eventually banging into what looks like a boiler. Annoyed Rosie looked up to see who attacked her.

"Clint what the fuck?!" she growled rubbing her shoulder that hit the boiler. Clint either didn't hear her or was too busy scanning the walls for something. Behind him Natasha was shooting at the men down the hall. Growling Rosie stood up and went to go help Natasha when Clint shoved something into her hands. Looking down she saw the hard drive before looking back up at him confused.

"You two need to get out of here, there's too many off them. I'll hold them off," Clint pulled Natasha into the room before slamming the door closed and blocking it with a crowbar. After he'd placed the crowbar he removed the cover of the vent he had spotted.

"Clint no! We're staying here! Coulson sent us on this mission together so we stay together! So either you're coming with us or we're staying- what are you doing? CLINT PUT ME DOWN!" Rosie squealed as he picked her up and shoved her into the vent quickly followed by Natasha. As soon as Natasha was in he replaced the vent cover and took out his bow.

Inside the vent Rosie looked at Natasha wide eyed. Was he crazy? Natasha looked at her and shrugged Rosie instantly understood.

"Does this a lot hu?" she said more in the form of a statement than a question.

"Yeah you get used to it, after a while you just stop arguing. Get moving we'll meet him at the Helicopter," Natasha shrugged. She had stopped arguing with Clint about two years ago. He was stubborn he was never going to let her stay. Rosie nodded and started to crawl through the vents. Not long after she came another vent cover. After allowing Natasha to see where it led she kicked it open before diving down into an empty hall.

"This way," Natasha ran off to the left. Rosie turned and followed soon coming out into field outside the compound. Together they ran over to the Helicopter and jumped inside Natasha in the front and Rosie in the back. With the door closed Rosie leant between the two seats.

"Are you sure Clint's going to get out?" Rosie asked.

"Well he usually does so I don't think today will be any different," Natasha muttered as she started up the Helicopter. Rosie sighed and sat back before putting on her headset. Just like Natasha had said minutes later Clint came running out chased by at least 15 men.

"Go," Clint growled when he jumped into the Helicopter.

"What have you done?!" Rosie screamed. Rosie looked to the thing in front of her. No, this can't be happening! Why would someone want to turn themselves into that!

"I'll be a great! Just like you! With this power I'll be unstoppable!" they screeched.

"It's not the power that makes you a great! It's who you are inside and what you chose to do with it!" Rosie screamed as wind started to pick up. Where it was coming from she didn't know.

"You're trying to ruin me! Just like he said! How could you? I looked up to you!" they screeched.

"He's a liar! He's using you!" she shouted over the winds.

"LIES!" they screeched just as a fire ball shot at Rosie.

"Rosie? ROSIE?!" Clint turned round and shouted at her. Rosie jumped at his shout. She'd blacked out again. Again that vision that had been forced into her mind at Jane and Thor's wedding took her away. Rosie looked up to Clint.

"What?" she asked only half there. Half her mind was in the helicopter and the other half in that vision. Clint sighed and ran a hand down his face.

"It was that vision again wasn't it?" he asked. Rosie nodded. At his Clint nudged Natasha and she turned round as well.

"Can you still not figure out what it's about?" she asked. Rosie just shook her head. It was three months after the wedding and she was starting to lose hope of ever cracking them. After the visions constant reappearance Thor had taken her back to Asgard to see if they could make the woman who made her have these visions in the first place get rid of them or explain them. By the time the two had arrived in Asgard they were greeted with the news that the woman had already been hung for her crimes to Asgard. Hearing this Thor had demanded that someone try and make sense of these visions but after weeks of tests they had gotten no further. So if the Asgardians couldn't figure it out what makes them think they could? It's magic. Asgardians understand it better than anyone. But then again, magic is just science we don't understand. Natasha sighed before taking off her headset. They weren't getting anywhere and right now they have to finish off their mission.

"We're here, better get to Coulson before he starts shouting at us again," she muttered. Rosie and Clint quickly removed their own headsets before they all got out of the helicopter. Looking around the flight deck of the Helicarrier her eyes landed on the door leading inside and a smirk pulled on her lips.

"Speak of the devil," Rosie smirked. By the door leading into the Helicarrier was Coulson. Clint laughed before pushing Rosie forward.

"He's less likely to kill you," he joked. Rosie laughed before walking over to her handler and hugging him. It had been weeks since they'd seen him. Well properly him. They'd seen holograms of him giving him their separate missions but not really him.

"Coulson!" she smiled, "It's good to see you! Well actually see you… Not busy with your team?" Coulson just laughed before walking inside. Natasha and Clint quickly sped up so they were on either side of their handler with Rosie trailing behind them. Coulson led them towards his now rarely used office.

"Well done good effort today you three. I think the title is ours again this year," Coulson smiled. Rosie raised an eyebrow. Title? What title? She was told nothing about a title… what the hell is going on?

"Excuse me?" she raised an eyebrow. Coulson turned round to look at his youngest Agent and youngest ever S.H.I.E.L.D. Agent. Rosie raised her eyebrow at him. Seeing this Coulson furrowed his eyebrows together.

"They didn't tell you?" he asked. Rosie scowled at him. Tell her what? What was another thing the two were keeping from her about S.H.I.E.L.D.? She knew normally when they kept things from her it was for her own good and that they're trying to protect her but still. She's a Stark, they need to know everything. It's an occupational hazard.

"Tell me what?" she hissed. Coulson laughed before turning back round. Rosie scowled at the back of his head. Will someone just tell her already?!

"That wasn't a real mission. It was S.H.I.E.L.D.'s annual handler compotation if you like. It's a yearly event where the handlers and their Agents each do the same mission and whatever team completes it first well win. Seriously they didn't tell you?" Coulson explained. Rosie groaned. Of course it wasn't a real mission. Why had she never heard about this before? She's been a S.H.I.E.L.D. Agent for around a year but then she didn't have a proper handler for a lot of that time since someone pretended to be dead.

"No," Rosie growled before looking to the hard drive in her hand, "So I don't need this?" Coulson shook his head. Rosie shrugged before chucking it at the wall. Smiling as she watched it smash into pieces. At the sound of something smashing the three in front turned to look at her eyebrows raised. Rosie shrugged.

"What?" she asked. The three just turned round and carried on walking.

An hour later Rosie walked out of the office. Clint had told her to go ahead and get a jet whilst Natasha and Clint sorted something out with Coulson. Lost in her own world she didn't hear someone squealing. She was just about to go into the hanger when someone came up behind her. When a hand grabbed her arm Rosie nearly jumped out her skin. Turning round she saw one of her many senior Agents. Rosie recognised him instantly as Agent Crichton. Rosie raised an eyebrow at him.

"Agent Crichton, do you need something?" Rosie asked.

"I hate to do this Agent Stark, but my daughter would love to meet you and-" Crichton was promptly cut off by a squealing girl. Rosie looked past Crichton to see a green eyed brunette about her age bouncing towards her. Rosie let a groan escape her before looking up to Crichton. Crichton gave her a look that said I'm sorry before putting his hand on the girl.

"Agent Stark this is my daughter, Olivia. Olivia this is-" Crichton started but was once again cut off.

"OH MY GOD! It's you! It's Rosie Stark, Iron Woman! Ohmygod! I can't believe it! AHHH!" Olivia squealed talking as fast as she possibly could. It was a miracle that Rosie could even understand her in the slightest. Olivia grabbed Rosie's hands and shook them rather widely. Crichton pinched his temple behind her catching Rosie's eye. As soon as she caught his eye she mouthed "Don't worry, I get this a lot. Can blame Tony for that". Crichton smirked her trying his best not to laugh. Olivia continued to shake Rosie's hands.

"Oh my god it's really you! You're my favourite Avenger! I love what you've done with the suit! You're amazing! I'm you're biggest fan!" she squeaked. Rosie was about to speak when someone shouted at her.

"Oi! Mini-Stark! I thought I told you to get a jet!" Clint shouted at her smirking.

"I know! I just got side tracked!" she shouted back. Out of the corner of her eye she saw Olivia start bouncing up and down. Rosie could only guess that seeing two of the other Avengers was a big thing for her.

"Well it was a pleasure meeting you Olivia but I need to go," she explained as Clint shouted at her to hurry up from inside the hanger, "ALRIGHT! KEEP YOUR FEATHERS ON I'M COMING!" Rosie pulled her hands out of Olivia's continuing to smile at her. As soon as she was in the hanger and out of Olivia's eyesight she let out a sigh allowing her shoulders to drop. Crazy fans like Olivia, was a bit much. Tony had told her how to deal with fans like that but she still hates it. Rosie was making her way towards the jet she saw Clint and Natasha go into when someone caught her attention out of the corner of her eye. Rosie turned and instantly froze in her place. Being led to a jet in handcuffs was none other than Winter Soldier. As almost as if he sensed someone watching him, Winter turned to the side and caught sight of Rosie. As soon as his eyes landed on her he smirked causing her to feel light-headed. With that Rosie started to sway.

"Rosie? Rosie!" she heard Natasha shout at her but her cries were very distant. Natasha's cries were soon over powered by a woman's blood curdling scream before Rosie collapsed to the ground and it all went dark.

Rosie woke hours later with the woman's screams still echoing in her ears. Groaning Rosie rubbed her head before looking around her. She was in her room in the Stark floor in Avengers Tower. Clint and Natasha must have taken her back. Whilst sweeping her room her eyes landed on Natasha who was standing by the door hidden in the shadows.

"Tasha?" Rosie raised an eyebrow, "What are you doing here? What happened?" Natasha moved over to Rosie's bed and sat down on the edge. Rosie watched her as Natasha turned to look at her. Natasha's face was lacking emotion. It was her Widow face. Oh great. Now she was in trouble. Fine, two can play at this game.

"I should ask you the same thing. You fainted as soon as you saw Winter. Clint, Coulson and I new Winter was being moved today and after what happened during the Red Room mission we were trying to keep you as far away from him as we can. We didn't want you to see him but what I really want to know is why you fainted," Natasha explained. Rosie looked away from Natasha to the bed beneath her. If Natasha was going to try and interrogate she'd play the stubborn teenager she's meant to be.

"I don't know," she muttered. Rosie knew that there was no way Natasha would have bought it. Natasha knew too much about what happened between herself and Winter in the Red Room. Mello, Hope, Kitty and Rogue had seen the whole thing and Steve the last part of the encounter. Natasha had asked all of them about what had gone down between the two because of her relationship with Winter from the Red Room. Steve had opened up willingly but the four girls weren't as willing to as Steve. They'd seen the whole thing and were confused about what they had seen. The conversation between Winter and Rosie had confused them even more. The three had refused to talk but after Natasha had had a proper talk to them they gave in and told her everything.

"What was it Ro? There's a reason, I know it. Why else would you attack Winter like how you did in the Red Room? Rosie I know he can play mind games but I need you to tell me. I can help you past whatever he did, whatever he brought to light," Natasha told her. No, she can't. No one can. Not that. Not what happened. They only way to get passed it is to forget about it and she was doing a bloody good job of forgetting before he showed up and messed the whole thing up.

"Once again I don't know why I fainted. I probably just haven't eaten enough. I attacked him like I did because I was sick fed up of him and what he's done to the team," Rosie spat. Natasha sighed before standing up. She was getting nowhere and she just didn't have the energy to fight Rosie at the moment but she promises herself that whatever it is that Rosie is locking up she'll get it out of her. She knows what keeping something big locked up can do to someone. Everyone needs someone to confide in and she thanks her lucky stars that she had Clint.

"I'll tell Pepper you're up. Once again you've managed to give Pepper another panic attack," Natasha muttered coldly. Rosie sighed as Natasha walked out her room. She hated lying to her team. But what happened with Bucky, what caused her to faint, what caused her to attack him, what made her try to kill him is something she is so desperately trying to forget.
