A/N: You know what's coming. Please review! And there it is. Two words that you are probably sick of by now. Sorry. But please review, even if it's just one word, just please. I'm begging again. Please?

Message to The21stquinn: you are amazing.

Natasha knew where Rostov and Drakov would be. There was a tiny office in a corridor that led from the experimentation lab, and it was the only place where the workers could relax from their busy lives of torturing helpless girls. It was a popular place to sit in, as you could watch the experiments take place each day on the giant screens that were in there. That was classed as fun there.

The other Avengers followed behind Natasha, taking in everything. They had only found out about her past around a month ago, so to actually see where it all took place was new for them. They didn't understand how anyone could actually put her through this hell. And it was hell. Everywhere they went there were rooms that Natasha had called the torture rooms. They were locked at all times until they were needed.

What was weird about all this was that Natasha wasn't as affected as they thought she would be when they came here. She was silent as they walked, only pointing out the different rooms she had been beaten up or trained in. But they knew that inside, she was being tortured all over again.

Natasha walked over to another red door, but it was bigger than all the rest they had seen and it didn't have any locks on it. Natasha took a deep breath as she pushed open the door.

The lab was exactly the same. She felt like she had turned into a 5 year old again, walking through the door for the first time, unsure of what would happen.

Steve stepped into the room first. Natasha followed, immediately breaking the security camera in the corner.

There was a metal slab in the middle of the room and trays surrounding it. They were full of needles and other medical instruments that looked extremely sharp. There were huge rubber wires hanging down from the ceiling just above the metal. Steve didn't ask, but Natasha knew what he was thinking. "This was the experimentation lab," she explained, "they chained us down to the metal and drugged us with enhancers and other things to improve us." "Then they would test our strength by attaching the wires to us and electrocuting us." She shuddered as she remembered the electricity ripping through her as she screamed.

Tony walked away from Natasha to the side of the room and found a small table with the folders stacked up on top of it. He picked one up and skimmed through it. He realised that this was the information about each girl that had come here. There was a photo attached, and every one he looked through had a red cross over it. He assumed that meant they had died. He searched through until he found Natasha's folder. Inside he found a picture of a scared 5 year old girl that had been taken from her home and everything she knew. He read the information.

Name: Natalia Alianovna Romanova

Age: 5

D.o.B: Unknown

Tony was confused. How could they not know her birthday? He continued reading.

Eye colour: Green

Hair colour: Red

Number of times experimented on: 67

Tests passed: 100

Tests failed: 0

First kill: Russian traitor, age 50

Kill count so far: 250

Tony threw the folder down. He couldn't continue. She had a kill count of 250. She was 5! How was that even possible? But the experiment numbers shocked him the most. How could a 5 year old girl survive 67 experiments? He glanced over to Natasha who was staring at the metal in the middle of the room, slightly pale.

How she had coped with this he would never know. Natasha looked up at Tony. She saw the folder and her eyes widened, knowing he had read it. "Natasha, how many times were you experimented on?" Tony asked, unsure if the number had increased. "150. They used to do it twice a week but it decreased when I got older."

150 times and she was still going. How? But there was one more question he needed the answer to, he wasn't sure that she would actually answer. He hesitated before asking. "And Nat, how many people have you killed?"

Natasha tensed and looked over to Clint. He nodded and gestured for her to tell them. "2576," she whispered.

Everyone was silent. No wonder she kept saying she needed to clear her ledger.

When they were done looking through the room, Natasha led them into a small plain corridor, with one door at the end. "They'll be down there," Natasha said. They didn't know how she knew, but then again there were a lot of things they still didn't know about her.

They silently walked over to the door and Natasha kicked it open. Rostov and Drakov jolted awake as they heard the sound.

When they looked up, there were guns pressed on their foreheads. Drakov gulped. He had planned to attack Natasha, instead of her attacking him. How had she found them?

Natasha meanwhile, was looking at Rostov. He was exactly the same, but his hair had gone grey. She remembered everything he had forced her to do for him and all she wanted to do was scream at him, but she forced herself to stay quiet.

Natasha wasn't going to question them, or take them to SHIELD. She was going to kill them, quickly. She wasn't going to prolong the deaths. She needed them dead.

Natasha looked Clint in the eyes and he nodded at her.

Before any of them could say anything, Rostov and Drakov were on the floor a bullet in each of their heads.

She walked away without blinking. She had an empty feeling inside of her, like a little bit of the darkness in her soul had gone. The others were looking at her a little sadly. They walked out of the room and they left in silence.

They sneaked out past the guards who were still unaware of their presence. They were going back into the forest when Natasha dropped down to an object on the ground. They heard a shrill beep and she told them to run.

Behind them, part of Natasha's past had exploded. They should have expected her to do that.

They were back in the quinjet within 5 minutes. They sat down, a little out of breath, but proud, not for themselves, but for Natasha. She had risked everything going back there but she still went and had showed them things they had never thought she would even talk about.

Natasha had fallen asleep against Clint but they knew it wouldn't be long before she woke up screaming. Half an hour later, it happened. Clint pulled Natasha out of her mind and walked her to the small bathroom that was on the quinjet.

They walked out together but didn't sit down. They had reached the SHIELD base. The Avengers walked out and saw Fury waiting for them. "Well done on your mission, Avengers."

They nodded and made to leave but Fury had shouted something at Clint and Natasha. Behind him, Phil was looking guilty.

"Have you got something to tell me Agents?" he called out to them.

Clint and Natasha ran for their lives.

They walked back to the Tower, where they found Pepper and Jane waiting for them, and Tony was looking suspiciously at them.

"JARVIS, what was Fury talking about?" "I am not sure I am authorized to say anything sir."

Clint looked at Natasha and she smiled at him. "Go ahead JARVIS."

JARVIS's automated voice spoke again. "Agent Barton and Agent Romanoff got married in Budapest 1 year ago, sir."

Everyone's jaw dropped. Clint and Natasha grinned at them.

So I wanted to bring back Natasha's daughter but then I realised she got shot in the head. Have any of you guys got suggestions? Or do you even want that to happen? Maybe the one that died was a clone, I don't know. Please help me!
