Vernon Dursely had far darker ties than anyone imagined. His mother had been an influential member of the communist party in Russia, and therefore, he had all of the right connections. All of the right connections, that is, to got rid of his niece.

Petunia didn't need to know. He'd told her that he was taking the brat to an orphanage.

His contact meet him at the airport. Vernon Dursley would never see his niece again.

Natalia Romonova was very uncertain about the two-year old in the Red Room. She didn't have a name, but Natalia had mental dubbed her Rosie.

The name fit her personality, the little girl was bubbly, happy, and unbroken. She wouldn't last very long. Not in the Red Room.

Natalia had yet to discover exactly what was in store for the young child, but she intended to find out.

Natalia watched horror as Rosie, her Rosie, sat broken and alone in the center of the technology filled bedroom belonging to her.

The Red Room had destroyed her. But not in the way Natalia had expected.

She had expected a hardened child assassin, void of all humanity. That was nowhere near what she'd found, nearly a year after she had first seen the little girl. No, those idiots had experimented on her.

They'd wired a computer into her brain. The possibilities were endless. She could hack into government facilities, learn anything she wanted without any lessons. But, all of that knowledge and power was useless, because how could anyone ever expect a three-year old girl to handle all the world's secrets and terrors.

Natalia hated them for it. It wasn't the first seed of resentment she'd felt against the Red Room, and it wouldn't be the last. But it was the first one that meant something. The first time Natalia had felt as though she may want to act on her anger.

Two years later, Rosie was much better. Talking again, learning to control the constant stream of information contained in her mind. Natalia, however, was closer to snapping than ever. It was no longer a question of if she would leave the Red Room, but when.

Natalia also knew she would be taking Rosie with her. She'd searched the girl's files thoroughly, determined to discover her real name, or even a family member. But, her little friend had apparently been donated by her own uncle, which settled Natalia's secret wish to keep the girl. Rosie already called her Mama. It had been a while since the heads had questioned it, so long as their information supplier was able to work, they didn't care what made her stable.

That's what Rosie was to them. An information bank. Natalia hated that almost more than anything else about the Red Room.. Because of something they had done, suddenly a child was degraded, at least in their eyes, to a thing. No longer a human.

Natalia was done playing their game. This time she was well and truly leaving.

Two nights later, the Red Room lost two of it's most valuable assets.

Three years later, Agent Clint Barton, of S.H.E.I.L.D., was studying his target. Natalia Romanova was easily the most elusive target he'd ever had, but she had finally used all her tricks.

She stood across the elevator from him. They were heading to the sixteenth floor, where he assumed she was staying.

"I'm going to ask you to hear me out, before you try to kill me. Please do."

Clint's eyebrows shot up in surprise. She wanted to talk? Maybe she was buying herself time, maybe she was trying to save her skin. Or maybe she was having some sort of a change of heart.

"Alright. I'll hear you out."

The elevator doors dinged open, and she stepped out, gesturing for him to follow. He did, and she led him down the hall, pulled out her key and unlocked the door. As they stepped into the hotel room, he heard a child cry out.

"Mama! He's not going to kill you! I need you! Mama!"

A tiny red hair girl of about nine was the source of the noise. She ran into Romanova's arms.

Romanov's smiled faintly, smoothing down the little girl's hair.

"Rosie, you were supposed to be asleep."

The child steps away from Roma- her mother? She wears an expression easy to read. Disappointment.

"Oh, Mama, since when do I listen to anything anybody tells me to do? In fact in the last hour alone, I've learned six new ways of building a hydro bomb."

Romanova sighs, before smiling gently. She is so unfurled, and gentle, he has a difficult time believing her file , which he has studied meticulously.

"That's my Rozi*. Now little one, I have some business to discuss, which may get messy though if all goes to plan, it won't. Go watch t.v. or whatever it is that normal children are doing nowadays.'

The child smiles, slightly demonic, before she tells her mother that television is stupid, and she will be reading Aristotle, as he at least had some common sense.

She exits, and Romanova turns back to him. " I'll work for S.H.E.I.L.D. under specific conditions. First, Rosie is a child, not a tool. With her permission, you may request information from her. She knows everything. Secondly, you will let me legally adopt her, and allow me to change my name. Are these acceptable terms?"

It isn't so much as a question, but more of a dare. A dare to say no.

He wasn't going to.

"Collect your things. I'll call a car, we leave in ten."

A/N Hey you loser's! This is my idea of fun. I think you will like it.

Basically, we will have an intellectual, slightly dark, female harry, with some badass assassin parents.

Review if you think I should continue.

I don't own Marvel, or Harry Potter. I own the concept of this story though

Also, I know I said I was taking a break, but writing romantic stories has become... Difficult in light of my sexuality. Yay. So little to no romance here. I think.

*Rozi= Rosie in Russian.
