Natasha's POV:
"Well I used some special technology that S.H.I.E.L.D is developing, it allows my clothes to stick to surfaces. It makes it easier to climb up buildings." I replied, folding my arms and smirking. They all stared at me with shock.
"S.H.I.E.L.D can make stuff like that!" Steve said, bewildered. It's funny that Steve still isn't used to the new world and all the technology. I nodded at him and he raised his eyebrows in disbelief. Tony just smiled and slung his arm around Steve's shoulders. I smiled at those two. I know they want to keep it secret, but being a professional spy and interrogator, it wasn't hard for me to figure out. Plus, they make it really obvious.
"So what are we gonna do with her?" Tony's sister asked. We all crowded around the girl as she struggled to escape the bindings. 'Good luck with that' I thought. She looked up at all of us, eyes filled with hatred.
"Midgardians, you shall release me at once before you regret it!" She screamed, shaking the chair from side to side.
"Oh yea? What are you gonna do about it?" Tony cockily asked. Steve sighed.
"Listen, I'm sorry. But we need to talk to you, and you don't seem too co-operative at the moment." Steve said, taking a step towards the girl. She narrowed her eyes at him.
"What is it that you need to know?" She asked, leaning forward as much as she could in the chair. Coulson stepped forward to join Steve.
"If you would just like to come with us and answer our questions, I promise we'll let you go."
"I think I would rather stay where I am thank you." She replied, leaning back into the chair. I looked over at Fury and saw that he was about to protest so I intervened.
"That alright. I can work with this." I found a nearby chair and placed it in front of her. "Hello. My name is Natasha." I began. "Who are you?" She hesitated for a few moments before taking a breath and answering.
"I am Elizabeth Odinson, Princess of Asgard and Goddess of the elements." I heard muffled laughter behind me, so I turned around and saw that Tony and Marie has their hands over their mouths trying not to burst out in a giggling fit. I turned back to see that Elizabeth was giving them a death stare. That seemed to shut them up.
"Asgard?" I heard Coulson ask from behind me. "That sounds familiar..." He trailed off, deep in thought.
"You must be talking about my brother, Thor. He was banished here four months ago. You may remember 'the destroyer'?" Everyone's eyes went wide, including mine.
"Your Thor's sister?" Fury asked.
"Yes, I doubt you know much about him. He isn't one for small talk." She replied.
"Ok, moving on. How did you get here?" I questioned.
"Since the Bifrost was destroyed, my father had to use a powerful magic even I'm not familiar with. And before you ask, the Bifrost is what used to allow us to travel between realms." Elizabeth shifted in her seat, trying to get comfortable. I pondered on what question to ask next.
"Why are you here?"
"It's a long story."
"We have time." Fury intervened. Elizabeth sighed and hung her head for a few moments before answering.
"A long time ago when Asgard and Jotunheim were at war my father, Odin, found a child. A frost giant baby. It was small, and most likely would have been outcasted when it reached adulthood if it stayed that way. No one knows what came over him, but instead of leaving or killing it, Odin took him home. It turns out that not only was that baby the prince of Jotunheim, but that baby was also Loki. My father and Laufey, the king of Jotunheim, formed a... Pact, I suppose. Loki was used as a symbol of peace, however he never knew. That was, until recently." She paused for a moment, taking this time to look out into the sky wistfully, her eyes filled with sadness. "When Thor was banished to earth, my father fell into Odinsleep, causing Loki to become the king of Asgard. During that time, he changed. He became bitter, evil. I don't know what happened, but I suspect that it was because he found out that he was Laufey's son. He invited the Frost Giants over to Asgard to kill Odin, and in return they will go in peace. However, when Laufey was about to kill Odin, Loki killed him. Or at least he thought he did. It seemed that the magic Loki used didn't kill him, but instead put him into some sort of deep sleep. Loki wanted to destroy Jotunheim to appear as the hero. He sent the destroyer to kill Thor, as you already know. Somehow, Thor came back to Asgard, and confronted Loki, who was planning to use the Bifrost to destroy Jötunheim. In order to stop him, Thor had to destroy the Bifrost. During this process, Loki and Thor fell off the side and almost fell into the void below. Luckily, Odin had woken up and was there to catch them. Thor was holding onto Odin, and Loki onto Thor. I was on the bridge too, trying to pull them up. I remember the look on Loki's face when he let go, plummeting into the abyss below." Her head was handing low, eyes shut tight. Everyone around her was quiet, a look of sadness of their faces. Even Fury's eyes failed to hide their emotion. "Just before I came here, me, Thor, and many others were attending a royal feast. However, we were unfortunately attacked by the Frost Giants, who wanted to kill me as revenge for Loki's death. So, in order for me to be safe, father used powerful magic to send me here. And that, Midgardians, is why I am here." She looked up at all of us, her face filled with sorrow. A few short moments of silence passed, before an obnoxious voice sounded. 'For God sake' I thought.
"Wow must have taken you a long time to perfect that soppy story, what ever your name was, Elizabeth?" Tony laughed meanly.
"I don't understand." Elizabeth said, cocking her head to one side.
"Bitch pu-lease, do you really expect us to believe that? Your probably some sort of lab experiment gone wrong. Listen sweetheart, we're not a charity. We're not going to take you in just because you're a little special. So how about we give you a lift back to whatever lab you came from and leave us alone, kay?"
"TONY!" Both Marie and Steve yelled at the same time. Steve hit him over the head and Marie punched him in the stomach. With a straight face I got up and turned towards Fury and Coulson.
"Sir, we need a plan. What are going to do with her?" I asked. Fury and Coulson both turned away from me, muttering something I couldn't hear. Turning back to the fight, I saw that Elizabeth had become angry again, and Tony was smirking annoyingly. Steve and Marie were shaking their heads in disapproval, desperately trying to get Tony to shut up. I heard Fury cough behind me.
"Agent Romanoff, we have come to a decision." I nodded, and stepped aside to let them through. "Elizabeth." Their fighting ceased instantly, all eyes on Fury.

Tony's POV:
"TONY!" Both Marie and Steve screamed at me. Marie punched me really hard in the arm to be honest didn't hurt and I was expecting so... But Steve went and hit me over the head. It didn't hurt but wasn't expected which kind off hurt. I looked at him with a 'what the hell' look.

Nat, fury and Coulson had turned around and we're discussing some thing important I'm guessing as their voices were a little hushed. My annoying sister and my sweet boyfriend were still staring at me. "What?" I asked and my mouth curved into a smile. Marie gave the most evil eye she could which just made me laugh a little under my breath. Steve on the other hand walked over to that rejected lab rat. He kneeled down next to her like the true gentleman he is.
"Miss Elizabeth, I realise you are not used to earth and it's way of living but-" he paused and looked at me "most of the people here are like him and are just pains in the backsides. Please don't get to offended by the ridicules comments that comes out my boyfriends mouth." As he said this he gestured to me then got up and walked over to me. Kissing me on the lips once he turned and walked to Marie standing away from me. Marie gave me a smug look, but I smirked and her expression went blank. 'My turn to have a bit of fun' I said to my self.

"I was serious you know, what lab do you need to go back to, I'm more than happy to take you." The corners of my mouth curved a little into a slightly crooked smile. Looking up I saw the shame in Steve's eyes, he mouthed 'don't' and shook his head. His beautiful blonde hair swayed as he did so. As I forced my self to look away I saw Marie was doing the same. However the failed lab experiment, Elizabeth? Just burned a hole in my skull. Her anger was quite apparent as her eyes had gone sharp, jaw clenched, tied hands in fists and she was shaking. 'Tony-1/Elizabeth-0' I announced to my self. It was quite amusing to me to see her so wound up.
"Oh mortal, you are so toying with the wrong goddess." Elizabeth's once hard set face had slightly softened and her face wore a huge ass smile. I just laughed and put on my best annoying smirk.
"Am I pushing you royal buttons?" I teased. Taking a step closer to her I forced a sweet smile. "Can I just ask which is the right goddess to 'toy' with?" Her face was now set again, this time with a deep frown almost a scowl. She opens her mouth to say something but unfortunately Marie stuck her nose in.
"That's enough now Tony." the warning in her voice was so prominent and her eyes had the same glow as the flames that Elizabeth once covered her self in. My little sisters hands were clenched by her sides and she was right I front of me, trying to be threatening I assume.
"Woah back off tiger, please don't eat me over a perfectly simple question. I'm interested is all!" I said putting my hands in the air in a mock surrender. She backed of stared at me for a few seconds then simply said,
"bite me you good for nothing son of a bitch." The venom on her words meant nothing to me just washed right off.
"I'd be carful baby sis, it's not nice to call mum a bitch, wonder what would happen if she found out?" I mocked smirking and staring at her. This time I took a step forward.
"Don't talk about mom like that." Marie said angrily, her stance changed almost to a fighting one. Steve was making his way over to wards us. He stopped only about a meter away.
"Oh shouldn't I? Well what are you gonna do about it?" My voice was tormenting and a smirk played at the corners of my lips. Oh how I loved winding up my sister. Instead of saying anything she lunged at me, grabbing my neck and wrapping her legs around me. She pulled me down to the floor and was about to punch my wonderful face when Steve came and lifted her off me. Getting up I saw that the lab rat was smirking at me.
"What you looking at bitch?" I shot at her. My comment didn't seem to faze her.
"Your sibling quarrels are quite amusing to me. The metal man, beaten by a young girl." She raised one of her eyebrows at me. "And how is it that a grown man is so small?" My face melted into a scowl.
"Well at least I'm not a rejected lab rat which quite frankly no one likes or can be bothered with!" I spat. Marie, Steve and Elizabeth laughed. My face went blank.
"I don't like you either Tony!" Marie sang and went to high five Steve but he looked kinda guilty. I folded my arms and stared into Elizabeth's eyes. She stared back. 'looks like we're having a staring contest.' I thought. After a while my eyes started to water, however before I gave up Elizabeth blinked.
"Ha ha! I win, sucka!" I yelled fist bumping the air. Marie shook her head but Steve just smiled.
"I thought you humans were better than this. Your all so petty, thinking everything is a game to be played. You act like a man but inside your just a child."
"Well at least kids know what's fun! Your so boring!" I replied, causing her face to turn into a dark scowl. I leaned forward smirking, our faces inched apart.
"Elizabeth." We all stopped and turned toward Fury, who was walking towards us. "I have decided to trust you. You can live here on earth, but only as long as you don't show your powers to the public." My mouth opened in shock.
"Fury, your seriously letting her stay! Send her back!" I argued, throwing my hands in the air. He turned towards me, arms folded.
" Mr. Stark. You may have the pleasure of looking after her. She will live here with you and you are not to let her go out alone, understood?" His face stayed blank as he spoke. Marie just laughed and high fived her self.
"Yay another girl in da house, finally someone to help me when you two are being mushy!" She pointed and me then Steve, then laughed again. Elizabeth looked amused again, boy how I wanted to slap her annoying face. Steve walked closer to me and hugged me. He leaned down so he could whisper in my ear
"I don't mind being mushy do you?" That made me laugh just a little. I got on my tip toes and pecked his lips twice.
"No I don't." I giggled. Boy how I loved this man. We disconnected our touch and turned to the rest of the group. "Alright, she can stay. But no burning stuff!" I said pointing to lab rat. She grinned and nodded her head. Natasha walked over behind the chair and untied her hands. She sprung up and did a small curtsy to Fury.
"Thank you." She said. Marie squealed and ran over to her, pulling on her arm towards the elevator.
"Oh my god I have so much stuff to show you!" Marie rambled on as they disappeared behind the doors, Elizabeth having a terrified look on her face.
"Well, we best be off. I'll be checking in every now and again." Coulson said, following fury out the doors. As Natasha waked past she whispered-
"Don't mess this up." After they all left I turned back to Steve and smirked.
"Now, where were we?"
