So I've been thinking about writing this story for a long time and have only just decided to start it now. This is a Pietro/OC and as a few of you may realise after reading the first few chapters there will be some changes going on. I hope you all enjoy this story and please review as it means a lot and I get an understanding of what you all think.

Avengers cause mayhem in city!

Hulk levelled city – Innocents killed!

Do we need the Avengers?

"It doesn't look good does it?" The woman that had welcomed me into her house muttered softly running her hand over the large protruding bump that announced her pregnancy. I glanced over to her noting the worry plastered on her face, knowing she was worried about not only her husband but the whole team.

"It never looks good," I grumbled to the woman as I shuffled over on the couch making space for her, bringing my legs up to my chest as I looked back to the screen watching as images of all the Avengers came on the screen. "They always blow it out of proportion," I added taking hold of her hand and giving it a short squeeze hoping it would reassure her. She gave me a soft smile her eyes shining with gratitude but I could still see the panic in her eyes. "I wish I was there,"

"You're on vacation and you still end up doing a job," I froze at her words, turning my head towards her slowly hoping she hadn't figured out the agreement I had made with Clint. "I'm not stupid sweetheart, I know you told Clint you'd watch over us while you were here and he wasn't. I swear you can't go five minutes without checking the perimeter."

"Laura -" I started only to be cut off by the shrill ring of my phone. I knew who it was because everyone else had a ringtone. "Quinn," I answered giving Laura an apologetic smile as I got up off the couch and peered out of the window.

"Hill here," Maria announced as if I would actually need informing that it was her calling. I chuckled lightly at her words feeling more amusement then I should.

"I know, caller ID told me that," I noted feeling Laura's gaze burning into my back as she tried to listen in on the conversation. That's what you got when you married a SHEILD agent and housed two more throughout the year.

"Right," Maria went on but I could tell that she was only half focused on this conversation. "The teams lying low right now. Clint's about an hour away. I know it's not reasonable but this is the only place the team has at the moment." She explained but she didn't really have to. I knew better than anyone that this place wasn't known about. "Pass the message onto Laura please,"

"Of course," I muttered feeling drained all of a sudden. If they were coming here than they were going into hiding. Was it really worse than I thought? "Are they all coming?" I asked feeling Laura sit up straighter behind me.

"That's affirmative," Maria sighed deeply on the phone and I could hear button's being pressed quickly through the phone and knew she was working on the computer at the same time. "I've got to go, tell the boss I'll be on hand if needed."

"Speak to you soon Maria," I mumbled softly ending the call and turning slowly back to the woman that was waiting for me to affirm everything she had just heard.

"They're on their way?" She asked and I could see the happiness leak through her eyes at the thought of her husband coming back to her alive. I nodded slightly turning my head towards the stairs as the two Barton children rushed down smiles on their faces.

"Aunt El, Cooper hit me!" Lila called running towards me, wrapping her arms around me as she shot her brother a glare. For a six year old she was fairly intelligent and already learning how to snitch on her brother. Cooper, the oldest Barton kid at ten looked sheepishly at me shrugging his shoulders when Laura gave him a disapproving look.

"Shall we bury him in the garden then?" I asked the six year old running my hands through her dark hair as I looked over to her brother with a small smirk on my face. He looked so much like his father and if he was to become like him as he grew then Clint and Laura had a lot of work to look forward to.

"We could never!" Lila cried out looking over to her brother with fear on her face at the thought of him being buried in the garden.

"Okay then," I smiled knowing that she loved her brother dearly even though they argued all the time. "How about you both go up into my room and watch that movie on my tablet?" I supplied knowing that both of them wanted to watch the latest Disney film again. By the large smiles on their faces and the way they shot out of the room, stomping on the stairs I took that as a yes.

"You're so good with them Elia," Laura stated as she picked up the blanket from the couch and folded it over the back, giving me a small smile. I never really had experience with children until I met the Barton's kids and having known them for the last two years they sort of became my younger siblings in a sense. "Help me make lunch for when Clint and the others arrive?" She asked receiving a nod as I followed her into the kitchen.

"Honey … I'm home," Clint's voice called causing Laura to look at me with wide eyes as she held Lila's art stuff in her hands before stepping out into the open living room – diner a startled look on her face. They had taken less than the hour Maria had stated which left her feeling slightly behind schedule. "Hi ... company … sorry I didn't call ahead." At his words I stepped into the open planned room behind Laura looking at the defeated looking Avengers. My eyes settled on Tony first making a quick calculation that he was fine before they drifted to Bruce. He was looking fine on the outside but I could see that he was mentally and emotionally defeated.

"This is an agent of some kind," Tony stated looking to Thor who nodded his head in slight confusion as he glanced back to Clint and Laura. I felt burning eyes on me then and turned to face the woman that was burning a hole into my head. Natasha sure as hell looked worse off than the others and I wanted to run to her then to wrap my arms around her.

She, along with Clint had been my mentors during training but over the last couple of years she had seemed more like a sister who treated me like any older sister would.

"Gentlemen, this Laura," Clint introduced his wife as he turned back to his team mates all of them but Nat looking confused. Tony raised his hand awkwardly while the others smiled slightly at the introduction.

"I know all of your names," she stated slowly as if it needed to be pointed out. The rushing of feet down the stairs indicated that the two youngest members of the household had finally realised that their dad was back.

"Oh, incoming," Clint muttered softly realising the same thing just as Lila and Cooper rushed round the corner, large smiles on their faces at the sight of their dad.

"Dad!" Lila called out rushing into his arms as Cooper hugged his side as Clint greeted them both with excitement. He hadn't seen them for the last two months, being busy with Avenger stuff and instead had me as his replacement – not like I was much. Only Aunt El to the two of them but according to Laura that meant a lot to them.

"These are smaller agents," Tony went on as if it could explain the little family gathering in front of him. I knew Clint hadn't told anyone besides me, Nat and Fury about his family so it must have been some shock to them.

"Did you bring Auntie Nat?" Lila asked as Clint set her down as he turned his head towards Tasha. I glanced at her seeing her straighten up and push away the pain she was feeling as she stepped forward scooping Lila in her arms.

"Sorry for barging in on you," Steve went on to say after watching Tasha hug Lila to her chest, looking towards Laura an apologetic look plastered on his face.

"Yeah we would have called ahead but we had no idea you existed," Tony added onto the end looking at Clint with a pointed look.

"Fury helped me set this up," he explained but he no longer had Tony's attention as the man was staring at me a slightly angered look on his face. Not liking the look he was sending my way I slipped back into the kitchen filling the tall glasses Laura had set on the side earlier with lemonade. I could tell a really long talk was going to take place soon.

"You knew about this?" Tony asked me from the doorway of my room looking slightly annoyed as I rested on the bed on my stomach, propped up on my elbows as I read the book perched before me. I glanced down to the book, taking in the page number before closing it and pushing myself up into a seated position.

"Where do you think I go when I'm not working in the lab or on a mission?" I replied setting the book on the bookshelf beside all my other books. Clint and Laura had given me my own room about a year ago stating I would be needing one as I was part of the family. It made sense after the long periods of time I spent here sometimes, like the two months I had been here on 'vacation'.

"I don't know because you don't tell me," he growled out his eyes roaming around the room until they settled on the desk that housed my laptop and a few photo frames. He stepped into the room then, walking over to the desk and picking up one of the photos. "This is your room? You have your own room here?"

"I am here between working at the lab, staying in the tower and going on missions Tony," I stated taking the photo from his hands and looking down at it. It was a phot of me, him and Bruce, the three of us at Christmas last year. It was one of my favourite pictures. "And I don't have to tell you everything," I added rolling my eyes at the look he was giving me.

"Hey that's not fair," he started but stopped when I raised my hand not wanting to hear it today. After all there was a murderous robot on the loose trying to destroy the world and humanity as we know it.

"Shouldn't you be talking to Steve? Trying to figure out how to stop Ultron?" I questioned setting the photo back onto the desk, stepping away from him. I sighed in defeat at the look he was giving me, running my hand through the thick curls that fell down my back, framing my face. "I told Laura I was going to help with dinner," I mumbled giving him one last look before leaving him in my room and venturing downstairs. Clint was waiting at the bottom of the stairs as if he knew I would be there at that moment.

"How was the chat with Stark?" He asked causing me to roll my eyes as we walked into the kitchen where Laura was already starting on dinner.

"He wasn't very happy," I grumbled washing my hands and taking the knife she offered me, starting on the load of vegetables needing to be cut. "I think you'll be receiving a few words about my room as well," I added knowing Tony wasn't happy about that either.

"He'll understand," Clint went on resting his hand on my shoulder in comfort before giving me a pointed look. "You don't make it better. Between the two of you I don't know how you can have a conversation without it being awkward."

"Clint!" Laura chided slapping her husband on the arm sending him a look that had him running from the kitchen. It was funny that a master assassin like Clint could get scared from one look sent by his wife. "Elia don't listen to him," she tried to assure me but I smiled at her knowing Clint was right.

"It's okay, I'm okay," I assured her looking out of the window and into the surrounding forest around us.

So Fury was here and not dead. That was a shook at first but I got over it when he gave me a short nod and asked me to fill him a glass of lemonade. And now they were talking about Ultron and how to stop him and I felt like I was missing something as I sat next to Tasha, actually I felt awkward being there because I felt out of place.

"So what does he want?" Fury asked looking around the group waiting for them to give him there ideas on what the murderous robot wanted. It was all like static in my mind as they all gave their suggestions about Ultron. I knew what he was made to do. Half the time in the lab Tony and Bruce went on about Ultron but he sure as hell didn't turn out the way they had planned. Instead of stopping war he had started war and wanted to end the world – not what they had in mind.

"Ultron's going to evolve," Bruce's voice cleared through the static in my mind bringing me back to the conversation just as he mentioned Helen Cho. I watched as they made their plan now, finally know that Ultron was going to get the good doctor to build him a body, each of them getting into action ready for the upcoming fight. I knew I wouldn't be able to sit this one out, I would fight with them. I couldn't sit this out not with my family out there fighting.

"You just had to make a murderous, maniac robot that wanted to destroy the world, didn't you," I groaned out to Tony rolling my eyes as the team all stopped to look at me. I knew they were wondering if I actually called Tony out on what he had done. It seemed Fury was the only one not shocked by my words as he chuckled lightly as he turned to me.

"I like you little Stark," he announced causing both me and Tony to freeze at his words. I could feel everyone's eyes darting between me and Tony know wanting to figure out what Fury meant. Only Clint, Tasha and Laura knew about the connection between me and Tony.

"Little Stark?" Steve questioned looking over to me before his eyes settled on Tony as if expecting an explanation. It looked like he was still frozen in his place but I knew he didn't want to tell them. That had been the agreement.

"Well if you're not going to announce it, I will," Fury groaned out a lot of disbelief in his voice as he looked to Tony before glancing to me and then to Steve. "You know Agent Elia Quinn," he started waiting as Steve nodded before looking to Tony as he went on. "Birth name Eliyana Aurelia Harley Quinn Rose Stark, daughter to none other than Tony Stark, aka. Iron Man."

"What?" Steve asked sounded confused and letting that confusion show as he looked between Tony and me. "But, but … she calls him Tony?"

"For her own protection," Tony finally spoke seeming to snap out of his frozen state as he looked over to Steve. "Her mom died during childbirth so she was mine but I didn't want her life ruined by the press. The birth certificate isn't on file so no one knows I have a daughter. She goes by her mother's last name anyway so she can't be traced back to me. We do fine, we make it work,"

"That explains a lot," Steve mumbled his eyes darting to me before he turned back to Tony a frown on his face. "That thing with Loki, he was getting at you, when he -"

"Don't mention it!" I called out remembering exactly what he was talking about. It was after all why I joined SHEILD in the first place and how I bonded with Clint so fast.

"Sorry," the captain muttered probably seeing the panic flash across my face. "I can't believe you didn't tell us," he accused looking over to my father with annoyance on his face and what I understood to be hurt.

"It's the same reason why I didn't tell you about my family," Clint supplied coming to Tony's aid as he stuck up for him taking away Steve's attention. "He was protecting her,"

"You knew?" Steve asked looking at the archer before darting his eyes to the red head still sat beside me as she kept a clear face. "And you?"

"They had to know," I mentioned indicating to the two agents that where my mentors. "They were training me after everything happened. They needed to know so they could teach me not to break." I paused as I looked over to Tony grimacing as I turned back to the captain as he stood in his suit ready for action and sighed. "If people were to find out, they'd take me to get to him. I couldn't afford that to happen. My dad … well he's my dad and he's given me everything I could ask for. He loves me and he cares about what I do. I won't allow myself to break so easily and give him up. It's not in my blood."

"Enough of this, there is still a robot out there that needs killing," Tony said stopping the silence that had begun after my words. There weren't many times over the years where we allowed our relationship to show and I knew he grow uncomfortable when other people knew that we cared for each other.

"I'll take Natasha and Clint," Steve announced as he walked through the hallway a few minutes later as Tony followed, me shadowing their movements. I had no idea where I was going but I knew that I would be fighting alongside them if I had my way. There was no way in hell I was missing out on the next fight with Ultron.

"I'll drop Banner off at the tower," Fury told the two men in front of me as we came to a standstill in the hall. I glanced up then not realising the man had joined us but jumped at the chance of getting out of here.

"I'll go with him," I input receiving looks form all three of them as Fury nodded at my words before looking to Tony.

"Mind if I borrow Miss Hill?" He added causing me to smile as the woman technically still worked for him.

"She's all yours," Tony said frowning and adding onto his answer "apparently," if I was correct in saying I would think he was slightly hurt that she had hidden that she worked for Fury. God he could be such a baby at times.

"You ready to go?" Fury asked me receiving a nod as I slipped my jacket on, zipping it up halfway and pulling my hair back over my shoulders.

"What do you plan on doing?"

"I don't know something dramatic I hope," he supplied indicating that I go with him as he went to fetch Bruce. I looked to Steve, giving him a small smile before directing my eyes to Tony.

"I'll see you at the tower?" I questioned hoping he would only go to NEXUS and not do anything stupid. Like he always tended to do. He nodded his head in agreement allowing me to breath out a breathe I had not known I was holding. I gave them both one last smile before following the path Fury had taken to get to Bruce.

"Stay safe," I called to both of them as I turned the corner seeing Bruce and Fury waiting by the door.

"Harley Quinn?" Bruce questioned as he wandered around the lab looking at the notes made by him and Tony. I smiled at his words knowing exactly what he was talking about.

"He thought it would be funny," I mumbled rolling my eyes as the older man chuckled at my words. "he had to name me," I told him looking down at the ring on my right hand, twisting it slightly as I went over what Tony had told me. "Mom died before she could do it. They had split up a couple of months before I was born. She told him she wanted nothing to do with him, told him not to bother with me because I wasn't his child. Sure he may have fathered me but he wasn't my father where it counted.

"He got a call three in the morning from Happy, he was trailing mom because she was close to her due date and when she went into labour he took her to the hospital. She had no one, no parents or siblings. She only really had dad but then they didn't work out. She asked Happy to stay and he did. Happy didn't call Tony before to let him know she was in labour, he didn't call until she was gone.

"Tony thought he was joking, pulling some prank. It was April fool's Day and he thought Happy was getting back at him for something he had done a couple of weeks earlier. He didn't actually believe I was here until he came to the hospital at Happy's instance." I paused looking to Bruce, noting the way he seemed hooked on my words as if picturing Tony when I was born. "He was twenty-six when he became a dad, twenty-six when he first held a baby and twenty-six when he realised it wasn't only him he had to think about anymore.

"They never spoke about baby names. That was always mom's job but he knew she liked the name Eliyana for a girl. I don't know how I got Aurelia but he told me he added Quinn to my name to honour mom and he just couldn't help by placing Harley before it.

"He hired Pepper then, to help look after me. She was already working for the company but he trusted her enough to care for me. As I got older the more important her job got. When I was old enough to look after myself she took her role as his assistant again. I never felt neglected by him though. Pepper may have been my main parent but Tony was always there. He was a dad to me and god did he spoil me rotten."

"It sounds like he cares," Bruce said when he was sure I was finished with my story. I guess he was surprised. Not many people had seen Tony as a caring guy but I had.

"He does," I admitted feeling proud that I was one of the reasons Tony Stark had a reason to care. "He would never show it but he's a dad. You ever wondered why he has me working in the labs with you two and not on some other floor." Bruce shook his head that clueless look plastered across his face.

"Because you're too smart to be down there," the man we were talking about stated alerting us to his presence as he joined us in the lab. I could tell by the shining off his eyes that he had heard what I had said to Bruce about him.

"You and I both know it's not because of that," I said shifting on my seat as I looked between the two men giving Bruce a look as I glanced down at the desk with a smile. "Last year one of the guys on the lower floors happened to ask me out just as he walked passed." I mentioned not able to keep the smile off of my face as I remembered the reaction it got out of Tony.

"What happened?" Bruce asked the smile coming out in his words. I could tell Bruce was already amused by my words.

"He fired him on the spot," I chuckled looking to Tony as he huffed, crossing his arms against his chest.

"Really?"

"That scumbag was going to touch my little girl," he grumbled turning away from us and we laughed at his words. I could see that Bruce was shocked by Tony's actions but noticed something else about him then. He wasn't shocked when he found out.

"You knew," I whispered looking at Bruce, my head tilted to the side. Bruce looked at me in confusion probably thinking I was talking about the guy Tony fired. "You knew he was my dad," I added wanting him to be clear on what I was talking about. He nodded at my words looking over to Tony as he froze at this new information. "How?"

"After the incident with Loki, I was checking your blood. I ran all the test and a match came up for DNA. I was confused at first because you both said you were here on a scholarship, you mentioned you were an orphan." He explained reminding me of the time when I was cooped up in the lab because of Loki. "The DNA results said that you were related to Tony and him being your father was the conclusion I came to. They were almost accurate so there was no other explanation. I was going to question him about it. Ask if he knew but I saw the way he acted around you when you were trapped in here, I knew then. I knew he knew and I knew you knew. I decided it didn't matter. It had nothing to do with me."

"You've known for three years and you never said anything?" I asked wondering how he had gone that long without actually having his theory confirmed verbally.

"I didn't have to say anything, I guessed at what was going on. That you both knew but were keeping it hidden. I knew there must have been a reason,"

"As nice as this conversation is, maybe we should get on with some work," Tony interrupted seeming to unfreeze from his spot as he dropped the phone that had been at his ear. Huh, I didn't even realise he had gotten a call. "Cap's bringing the cradle to us," he announced rubbing his hands together as he looked between me and Bruce a plan already formulating in his head.
