Hi! So this is my first english ff. (it isn't my first language so pls be merciful) If you haven't watched aou you should know that this ff contains some major spoilers.

The wind has to be really cold up here.

That was the only thing Pietro thought while he ran straight to one of the last standing headquarters of HYDRA. But of course the wind barely even touched him. With his super speed he shot through it like one of Barton's arrows. To his advantage cause despite the super fancy and multifunctional supersuits of the other Avengers he just wore some robust pants, a flexible shirt, not one of those he used to wear but one made of a special material that didn't heat up even at his extreme speed, and his running shoes.

It was, compared to the fight in Sokovia, a small mission.

He still shivered when he thought about the battle that happened 6 months ago.
He almost died back then, the scars from where the bullets hit him still reminded him of that every day. If he wouldn't have had his fast metabolism, which caused the wounds to heal immediately after he was shot, he would have died, that he was sure of.

But he was almost over it. Together with the help of his twin sister and his new friends in the Avengers he fully recovered.
Just the memories sometimes haunted his dreams.

To forget everything he poured himself into work. He made long training sessions every day to improve his powers and took part in every mission the Avengers had. Of course he noticed that his sister was worried about him, but he told her that he was fine every time she asked.

He just needed some time. And some distractions.

This mission was perfect for it. Even though HYDRA was destroyed there where still some offshoots, trying to do their own thing and taking part in some crazy world-destruction plan.

As soon as they found the base they assembled a small team, consisting of him, Captain America, Black Widow and Iron Man. All members weren't around all the time in the Avengers headquarter, but they came back when they really needed them. Except for Bruce Banner whom they still haven't found a trace of.

The base was set in Russia, just a few kilometers (according to Pietros thinking of 'few') away from where the big battle happened, making him unwillingly think back about what happened there.

"I got some information." he heard Tony Starks voice through his earphone, "The base is fully occupied whit heavily armed HYDRA agents so watch out that you don't get perforated."

Quicksilver laughed, knowing that this comment was meant for him. He still had some trust issues toward Tony Stark but he kinda liked his humor.

"Also it seems like this base was more of a laboratory where they did some plain crazy experiments. Maybe with humans." Stark added after a short break.

Silence followed and Pietro wondered if he was meant to say something about it, being one of those experiments.

"If," Stark continued, "if there should be some human experiments it would be the best if we get them out of there and bring them to our headquarter. But be careful 'cause I have no idea what kind of experiments those could be. Got it?"

"Got it." Pietro answered at once with the rest of the team.

He didn't quite know what he should do with this information. He very well remembered the time when they experimented with him and his sister. It was a horrible time and they both barely survived the mutations their bodies have gone through. It made him angry thinking that maybe some other people had to go through this against their will.

But he didn't had much more time to think about it cause they had reached the base.
Together they stormed in.

As Tony said it was full of armed HYDRA agents. Together they fought them, trying to get further into the building. Pietro speeded through the barely lit aisles, dashing past horrible looking labs and knocking out some of the men on his way.

He quickly recognized a similarity. This base was built exactly like the one he and his sister were held in.

Like in trance he ran along the aisles, on and on to the part of the building where their rooms used to be.
When he reached the dorms he slowed down. He stood before one of the heavy metal doors that were along the aisle. It had a little window whit heavy bars. Pietro looked through it.

The room was barely lit but he could still see something. On one side stood a bed and on the other a sink and a toilet. He almost passed to the next door when he noticed two eyes staring at him. In one of the dark corners sat a child, looking like he was not older than 8.

"Are you alright?" Pietro asked through the small window.

The boy shook his head.

"Okay listen, I'll get you out of there." he said.

He took a step back and hit against the door with full force. Nothing happened. He quickly ran back and grabbed a gun of one of the soldiers he knocked out. He came back and shot at the keyhole. Then he tried once again to kick it down and this time it worked. He saw the boy flinch as the door crashed to the ground. Pietro went to the boy and kneeled down to him.

"Everythings' alright. I'm gonna get you out of here, okay?"

The boy nodded with big eyes.

Pietro picked him up and dashed through the door. But as soon as he got back into the aisle he heard a loud explosion. The heat wave almost knocked him over.

"Get out of here!" he heard Steve shouting through his earphone. "They knew we were coming! This whole building is about to blow up!"

Pietro nodded and was about to run off when the boy said "Wait! You can't leave Ilea here!"

He pointed to the door next to his. Pietro quickly dashed to it and looked through the window. It was exactly the same room but in this one he could see a person laying on the bed.

"Pietro where are you?! Get out!" he heard Tonys voice.

"I need your help!" he replied.

With the boy he dashed toward where he think the voice came from and found Iron Man a few aisles ahead.

"Here, take the boy and get out I'm coming immediately!" and before Tony answered he handed him the boy over and dashed back.

He went to the next door and kicked it in. He dashed to the bed. Now he could see that it was a girl, about his age. She seemed to be sleeping what he couldn't quite understand since the first explosion should have woken her up. But he didn't had much more time to think about it. He quickly picked her up and ran back to the entrance, out of the building and back to the jet.
He heard the loud explosion of the building and felt the heat on his back but continued running till he reached the others.

"Man, I thought you wanted to stay in there." Steve said as Pietro climbed in the jet. He carefully laid the girl on one of the benches.

"You managed to rescue another experiment?" Natasha asked and surveyed the girl.

"Good job." Steven said and slapped on Pietros back that he almost fell over.

The little boy who sat at the other bench ran over to the girl as soon as he saw her.

"Ilea!" he whispered and grabbed her hand.

Steve kneeled down to the boy and put a hand on his shoulder.

"What's your name kid? And who is she?" he asked him softly.

The boy hesitated shortly.

"I... I'm Jamie. And this is my sister Ilea. Um, but not my real sister I just call her like that."

Steve nodded.

"And do you know why you were in there?"

Jamie got a kind of scared expression.

"They… they did strange things with us." he pointed at his wrist where you could see some small red injection sites. "Every week they put things in our arm and then lock us in our rooms. I always got ill from this stuff and I don't remember much. I don't know what happened to Ilea when she was in her room." he began to tear up.

"It's okay." Natasha said calmly. "Just one more question. Where you the only ones?"

"I don't know." Jamie answered "I've only ever met Ilea."

Natasha nodded.

"But why is she sleeping?" Tony asked who sat behind the helm of the jet and now turned around.

Steve shrugged. They just stood there and obeyed Jamie and the girl.
Jamie just stood there and held her hand, then he nuzzled his face in her shoulder.

As if she felt his touch Ilea slowly opened her eyes.

She first gazed into space until her eyes slowly wandered to Jamie. She looked at him for a while than smiled lightly.
Her pupils were so big that you almost couldn't see her eye color.

"They drugged her." Pietro said.

Everyone turned to him.

"They sometimes did this to Wanda." he continued "If she got too destructive they drugged her so she wouldn't devastate everything."

Meanwhile Ilea had closed her eyes again.

"We really need to bring them to the headquarter." Steve stated.

The others sat back down, everyone lost in their own thoughts.

Pietro continued to watch Jamie and Ilea.

They both looked exhausted, whit dark circles under their eyes and hollow cheeks. Ilea was a bit too pale and her long brown hair looked dull. Still she had some specific kind of beauty.

It made him angry to think about how they both had suffered.

He leaned back in his seat and closed his eyes, trying to get a bit of sleep on the rest of the flight.

I need to tell you that I won't be able to update regular because of my work schedule (I'm working as a nurse) but reviews can be some big motivators ;)
