:Chapter Three:

"What is this for?" (Y/N) poked her chest, feeling the cool metal under her sports bra.

Tony wiped his hands, "Because your powers-"

(Y/N) raised her hand to stop him, "Please don't call them powers, they are a curse." she spoke quietly.

The genius nodded, "Because whatever those people put in you has surged through your body at an incredible rate, your heart has been silently under attack by it. Neither I nor Bruce knows what it is but we are trying to figure it out."

The young teenager stared in the mirror, watching as he skin healed itself around the new wound, "So, what does it do?"

"It's practically a deterrent. It's kind of like mine," Tony motioned to the light beaming from under his t-shirt, "But where mine keeps shrapnel from entering my heart, yours prevents whatever antibody they gave you from entering yours and instead changes it into something useful that your body can handle."

(Y/N) tapped at the small light coming from her chest. She had only been staying with the Avengers on the helicarrier for a week, and this was the first thing that Dr Banner had picked up on. He insisted on something needing to be done to protect (Y/N) from whatever was travelling through her veins - no one knew what it was.

"Do you think we'll ever find out what they put in me?" (Y/N) asked quietly. She was still new to socializing with others, but she was slowly starting to trust Tony. He was like a father figure to her already and she enjoyed learning about his robotics.

Tony looked at the vulnerable teenager sat near his desk, staring at her new chest piece. He hated this. He hated having the arc reactor in his own body, and he had to just install one into a young innocent girl who hadn't done anything wrong in her entire life.

"I don't know." he sighed walking before sitting down beside her, "But I promise I'll do whatever it takes to help you - you don't deserve any of this."

(Y/N) suddenly wrapped her arms around the genius, startling him slightly. He wasn't used to this affection from people but he wrapped his own arms around her to comfort her. "Thank you, Mr Stark."

"Hey, hold still, I need to get this bit of glass out of your stomach." Tony muttered, sending a playful glare at the teenager.

"But why! My body will heal on it's own!"

"Not if you keep that glass it won't. It'll become infected and then we'll have something bigger to deal with." The genius sighed.

(Y/N) flinched as Stark removed a large piece of glass from her side, "Have you been taking lessons from Dr Banner or something? I thought robotics was your thing?"

Tony gently as possible pulled the last piece of glass from her side before watching as her body quickly healed itself - that still impressed him to no end. Whatever (Y/N) had been tethered with all those years helped her in some ways.

"I still know a little about medicine and all that crap you know." he answered, leaving (Y/N) to chuckled at him.

"Hey, guys!"

The two looked over to the door to find Pepper Potts walking through, two cups of drinks in her hands, "Hi, Miss Potts!" (Y/N) smiled, gratefully taking the (F/D) from her.

"Hey, honey." Tony smiled, giving her a small kiss.

"So, (Y/N), how are you feeling? I heard you went on your first mission earlier." Pepper grinned at the young female, knowing that she had wanted to go on a mission since she found out about the Avengers.

"It was great!" (Y/N) exclaimed, "That God is no match for me!"

"Calm down, squirt." Tony chuckled, "You should've heard him during interrogation. He said that you were no match for him."

(Y/N) hummed, "Yes, that's why I was able to drag him back to his cell."

"You dragged my brother back to his cell?" A surprised voice broke out, leading the three of them to stare at the God of Thunder walking into the room.

"Surprised, Point Break? (Y/N) isn't just a sweet bag of sugar." Tony smirked.

"Shush, Mr Stark! You'll give away my secret identity!"

"Oops, sorry!" he shushed himself, playing along. This small action caused Pepper to smile at the two of them - she out of anyone in the helicarrier knew the most that Stark was close to (Y/N).

"I'm sure she is." Thor nodded before continuing, "However, I've come to say that I am returning to Asgard for a while."

"What, why?" (Y/N) asked, sounding disappointed.

"It should only be for a short time." Thor said, "But with Loki's escape, I need to return to the Allfather to discuss our options on what to do with him. Knowing that he's escaped an Asgard prison makes him dangerous. And although I love my brother dearly, he still needs to be kept in check."

"That's exactly what I was coming to discuss with you." Another voice broke through.

"Is this a meeting in my lab now?" Tony muttered towards Pepper, who simply smiled at him and wrapped her arm around him as comfort.

"What is it that you propose, Director?" Thor asked.

Fury walked towards the four, handing Stark a folder, to which the billionaire kissed the back of his teeth at, "I don't like being handed things."

Pepper rolled her eyes at him and took the folder from Fury before giving it to Tony, "Better?"

Tony grinned, "Much."

Fury began to speak again, "As we now know, Loki is capable of escaping even the most vast prisons. And as much as I hate to say it, is there any point in keeping him in prisons knowing he will always escape?"

"Are you saying that we let him carelessly walk around the helicarrier?" Tony rolled his eyes, "Because that's a stupid idea."

"I'm very much aware of that fact, Stark. However, I'm talking about more of a rehabilitation method." Fury stated.

"Rehabilitation? I don't understand." Thor spoke.

"You mean train him, make him see the error of his ways?" Pepper asked, leading Fury to nod.

Tony chuckled, "You really think that lunatic will come through? He tried to take over this planet."

"That's why you'll be guarding him." Fury told the genius, "I'm suggesting a process were we teach Loki wrong from right, and perhaps he'll change his mind about trying to rule Earth."

"I'm sorry, but didn't he get Barton to shoot you?" Tony asked.

"Doesn't Loki have powers?" (Y/N) asked, "Won't he be able to escape easily?"

Thor thought for a moment before speaking up, "I understand what you mean by this ordeal. If I speak with the Allfather, perhaps he can limit Loki's powers whilst on Midgard."

Fury nodded, "And I want him off this helicarrier, I don't fancy getting shot again." he looked pointedly at Stark.

Tony raised his eyebrows, "You're seriously thinking about making me take Loki back to the same tower he almost killed us all over?"

"I'm not thinking about it - I'm telling you to." Fury told the genius, "We'll provide the money for his food as such-"

"Do you really think I need money to keep one extra guy in my house?" Stark muttered.

Fury ignored the arrogant man before turning to the female watching everything take place, "And I want (Y/N) to live with you and be his guard."

"What?"

"No." Stark muttered, "(Y/N) has enough going on with herself right now as it is. She doesn't need an irritable, dramatic God on her tail."

"It's the best option." Fury looked at the female, "(Y/N) is capable of keeping Loki in check, she was able to drag him back to his cell even at his most powerful - does that not tell you something?"

Tony looked conflicted, not wanting (Y/N) to be put in any risk around that being.

"Mr Stark, it does sound like a good idea. I could stay with you, and in doing so we'll be able to continue in the lab, and I'll kick Loki's butt when he gets annoying!" (Y/N) grinned.

The genius sighed, "Fine, but if he makes one wrong move, he's out whether he's dangerous or not." Fury nodded at Stark's consequences.

"Can I see him?" (Y/N) asked, turning her attention to Thor.

The God of Thunder looked at the others before turning back to her and nodding, "I suppose you could come with me. I need to have a talk with my brother anyway."
