TC Stark: Hello! It's been a while since I've written anything Marvel related, but this is an idea that's been floating around since I saw Avengers 2. I really would like this to be a relaxing project for me and I hope anyone who reads it will like it too. I have taken some liberties, such as Pietro actually living after the events of AOU and breaking up Bruce and Natasha. I'm sorry, it just didn't work. Besides that, I would like to stay as in character with everyone as possible. So, if anyone sees any discrepancies, please point them out. Thank you!

Also, please "like" my fanpage pages/TC-Starks-Writing-Corner/1377045832592468 :) I post a lot of stuff fandom related as well as my own works.

Disclaimer: If anyone has read my "Whatever Time We Have Left" story, I am reusing Tilda. I found with that story that I never developed her properly, so I'm revamping her - giving her a fresh coat of wax and throwing her into this story. Also, as much as I love the Cap, I've realized (in my head) she is much better suited in this AU, as this is a Pietro/OC story (with small parts of Cap/Black Widow because they're my OTP). This story is rated M for mature content, such as sex, violence, death, language, etc. I try not to ever be too vulgar, but also don't believe in censorship. This story deals with the serious issues of a fatal medical condition, so there's that. I do not own anyone, except Tilda and my ideas.

Chapter One

They had thought he was dead. It had seemed logical enough. If someone got shot multiple times and collapsed on the ground, not moving for several hours; it seemed the plausible conclusion would be that he was dead. It had been a real shame, considering they had all just started to work well together.

What none of the Avengers had taken into account, was that Pietro Maximoff's cell structure was different than the average human's. Not only did the man have the ability of super speed and a incredibly fast metabolism, but also a very fast healing system. Sure, at first his body did shut down, but after a few hours, the bullets were popped out and all the wounds were closed. Quicksilver had jumped off that table so fast it had given the coroner a heart attack - luckily, he survived.

It had been a whirlwind of emotions for the Maximoff twins. All they had had in life were each other, and for a brief moment, Wanda had truly thought Pietro was gone. Her brother had woken up to find out the Avengers had beaten Ultron, were now based in a new facility in upstate New York, and his sister seemed to have a...friendly relationship with The Vision.

"But, I look good, no?" Pietro smugly asked, as he and his sister sauntered throughout the facility. Though their homeland was on the other side of the ocean, they knew now that they were Avengers and their lives could never turn around to go back in the past. It actually felt good, like having extended family.

Wanda gave a warm, kind smile while reaching up to tuck a strand of hair behind Pietro's ear, "Yes, very good. I would not think Avenger's facility would have beauty salon in it."

With a shrug, Pietro waved his hands in a circle, "It is Tony Stark - he's vain man."

The experiments the enhanced twins underwent had left strange side effects. Oddly enough, what had bothered Pietro the most, was what it had done to his hair. The blonde had made him look as if he had gotten a terrible dye job, and whoever had done it bleached it too much. Now, at least he looked more natural.

As the twins strolled around a corner, Pietro turned to ask Wanda in their native tongue, "Who is that with Natasha?"

Living in the Avengers facility, they were used to seeing other former SHIELD agents. Nick Fury had a bit of a following that those who were blind to Hydra's secret operation, had followed the director even after the disband. Natasha wasn't very talkative to those she didn't deem trustworthy, so seeing her so casually speaking with someone was odd.

Only about two inches taller than the Black Widow, this other woman wore the typical outfit Pietro was used to seeing SHIELD agents wear. Black leather pants, thigh holsters, combat boots, and a tank top most women would wear to the gym. A black headband kept wisps of hair out of the stranger's face. She too must have seen the facility's barber shop, as her hair was long and unnaturally orange.

This woman had the typical body of an agent. Feminine curves, with a toned behind (he looked, he couldn't help himself), flat stomach, and what looked like an average sized chest. Not as big as Natasha though - God, he shouldn't have been so observing when it came to his female coworkers, but he liked to think he was that way with everyone. Everyone was unique in their own ways, he liked to think he was just seeing everyone's little details.

Whoever she was, she had peach colored skin and green eyes. Her arms were defined, like someone who did a lot of pushups and pullups. Her right arm was covered in a full sleeve of tattoos, though Pietro couldn't make them out. Neither he nor Wanda had any ink, though it was common for the poor class in Sokovia to get depictions of how hard life was on their bodies.

"You two gonna keep staring or be social?" Natasha gave a small smirk, her sultry eyes shifting over towards the twins.

Moving closer to the two agents, the other opened her body to the Maximoff twins and looked both up and down, "So, these are the enhanced, huh? Sorry I missed out on all the fun."

Natasha amusedly rolled her eyes and introduced, "Agent Tilda Stygar has been based in our Australian base for the past few years."

"Before shit hit the fan and we all found out we were working for some crazed Nazi organization," Tilda scoffed with her arms folded, "What a disaster it was trying to regroup, save whatever we could, and not be hunted. And you guys were secretive, took me forever to get in touch with Fury."

"Well, we weren't exactly that liked - Hydra and all. Anyway, this is Pietro and Wanda. The Maximoff twins."

They all exchanged simple nods, while Wanda tilted her head and asked, "I recognize the name Stygar."

Tilda gave a crooked smirk, her eyes holding a small glimpse of rue, "He was an infamous Swedish doctor known for experimenting on his daughter. I think he wanted to be Sigmund Freud of something. He actually tried to replicate Captain America's serum because he was obsessed with the guy, but can you believe he actually ended up dying of cancer?" She nonchalantly shrugged, winking at Natasha before leaving.

Pietro's eyes temporarily followed Tilda's behind, before Wanda gently smacked his arm. Sometimes, her brother could be a real dog. Back in Sokovia, he certainly got a lot of attention from the female gender, and even some men at times. While he was always suave and kind towards those who gave him all that confidence, the twin didn't remember him hardly acting on it - he could have been a real man whore, if he had wanted to be.

Turning towards the Black Widow, Pietro asked, "She friend of yours?"

With a small shrug, Natasha answered, "She was one of the first people I met when joining SHIELD. I would say our paths have crossed a lot."

"Whatever happened to Dr. Stygar's daughter?" Wanda asked.

"That was her."

Dr. Bruce Banner was sitting at one of the desks in the Avenger base's laboratory, looking through a microscope, when Tilda walked in. It had taken a few weeks, but the doctor had finally returned to the Avengers. Albeit embarrassed, he stepped back in with his tail between his legs and went back to work. It was not easy being The Hulk. Everyone thought it was a great asset, but it was his burden and it was a heavy weight to bare.

Things had been awkward at first in the base, but eventually Bruce and Natasha came to an understanding that a relationship between them would not work. It felt forced and perhaps they wanted to really liked each other, but there was nothing there other than a good friendship and mutual respect.

"Dr. Banner, right?"

Looking up from the microscope, Bruce removed his glasses while standing up to shake the agent's hand, "Yes, but please - Bruce. Tilda, right?"

Tilda nodded, as Bruce let her to a different portion of the lab. Everything was incredibly clean or almost futuristic. It must have been a scientist's dream to have everything Tony Stark could provide at his disposal. There was equipment there that other researchers would have sold their souls to own.

"So, I read your files." Bruce started, retrieving a few items before walking over to him.

Green eyes watched as the doctor prepared a syringe to collect a blood sample, "Last time I had a checkup was in London - last year. I didn't have any time to really see anyone else, y'know with the whole Hydra, SHIELD thing going on."

Bruce nodded, looking around and seeing he left the disinfectant on another table. Before he was able to retrieve it, the item floated towards him and hovered in front of the doctor's face. He looked skeptically at Tilda, who only raised an eyebrow at him before he reached out and grabbed what he needed.

"So, it's true. Telekinesis?"

Tilda nodded her head, "Yep. Started bending spoons with my mind when I was ten. My real potential hit when I was sixteen. Just a couple of years before my father died and SHIELD got me. Hm. Nine years go by fast."

As Bruce began taking blood, he asked, "I read Dr. Stygar stretched out your serum intakes over the years. That's a lot of exposure for a young person."

With a shrug, the orange haired woman responded, "Yea, well - dad was convinced that you just didn't have the serum down right. That he could perfect whatever formula was used on Captain America and make a female version. I don't think he ever really liked the telekinesis thing, but rolled with it," Snorting, she added, "Steve Rogers' face was plastered everywhere in our place growing up. It was what I was supposed to aspire to. Haven't met the guy yet, he seems cool, I guess."

"He is a very good man," Bruce nodded, before finally asking, "How many years did they give you?"

There was the question she was expecting. Looking down at her nails, Tilda shrugged, "Ten. They said it could change, depending if the deterioration of my cells decided to increase. Guess daddy didn't calculate that all that extra exposure to radiation might actually do some damage."

"I'm sorry."

"I'm not sentimental," Tilda shrugged, "It's something I've made peace with a long time ago. Your quality of life kind of goes down when the only reason you were really born was to be experimented on," Cracking a small smile, she commented, "But, you didn't ask me to come see you for my life story."

"No, but I did ask you here because your case is well documented and Dr. Stygar did get a lot of media attention before his death. I don't...I don't know why anyone would mess with that serum, especially after what happened to me."

As blood was being drawn, Tilda explained, "Because science won't ever rest."

"That was your father's famous line during his court hearing."

The enhanced agent nodded, as if realizing that she did indeed quote her father, "Well, the old man had a flare for dramatics. Like Stark."

Bruce snorted, "You haven't seen dramatic until you've met Tony. He's definitely more of a fan of...public speaking than I am, but...he is a genius. Our working relationship really benefits I think so. Well...besides Ultron, I guess."

And almost leveling New York City. Tilda refrained from saying that. People often didn't like having their failures pointed out. Sometimes, social interaction wasn't her best quality, but from being with SHIELD, she had learned a lot that her parents had neglected to teach her. Her mother and father hadn't been married, nor even dating. They were just colleagues who decided to have a child through artificial insemination, as sexual intercourse seemed repulsive to them.

After Bruce collected what he could, Tilda slid off the medical table and cracked her back. The doctor observed that she seemed to be in good health. Physically at least. Perhaps she was a little too aloof at the idea of dying, but heart rate was fine, brain function was good - he supposed he really wouldn't know how her cells were doing until he got them under a microscope, and he didn't want to do that with her around.

Shaking her hand, Bruce explained, "I'll try to get these results as soon as possible. You're living on base now, right?"

"Yep, um, third floor I believe. I just got in this morning. And take your time, Bruce, I'm in no rush," Smiling, Tilda nodded, "It was great meeting you. Guess we're connected in some weird way, huh?"

"Weird, definitely."

Tilda smiled, while turning around to leave. It was just then that Steve Rogers was walking in, dressed casually as he had just been out with Sam Wilson. The two hadn't met, but Natasha had informed him that they had a newcomer in the facility. As the unofficial Captain of the Avengers, he had wanted to meet the newest edition.

Tilda though, hurriedly walked passed the captain and out the door. Befuddled, Steve turned towards Bruce and asked, "Who was that?"

"Your biggest fan. I think."
