I tried okay?! This isn't the best chapter I've ever wrote mainly because I wanted to get on with my main avengers story line. Warning that this chapter contains violence and blood.

Enjoy!

'Clint what's the word with Romanoff? People really starting to pile up here. We could really do with the target!' Steve asked, agitation sprang from every word as he was fed up of fighting. However a part of him was worried about Natasha, radio silence was still in place but even a word or grunt down comms was expected, and seeing as it had been well over 10 minutes he could feel something had gone wrong.

'Nothing Steve, it's a big building though and you know how Nat stays on radio silence until contact. Give it another 5 minutes and I'll head in'

'I could go check in, I don't like the atmosphere' Tony pitched in, he was also worried then a idea came to him.

'Banner! You there?'

'Woahh yeah yeah, what's up?' Bruce had just been asleep, so hadn't actually registered what commotions had happened whilst in his slumber.

'I need you to get some thermal imagining of the building, look for 2 people inside. Then if something goes down we know'

'On it'

As Bruce tapped away at the keyboard, he eventually gained an imagine of 2 people, stood inches away from each other, talking.

'Well, Stark they seem to just be talking'

'What?'

'Well Anna, shall we talk or get on with it?'

'Awww Natalia how I've missed you, why don't we talk? You're not in a rush are you?' Sarcasm bounced of her voice like a trampoline, if Nat wasn't annoyed before she definitely was now.

'No I'm not but sooner or later my friends are going to figure somethings up.'

'Friends are they now? You've become soft! What happened to your training? Did you forget or have you pushed those memories so far behind you than you can see them? You can't run forever Natalia'

A chill ran up Natasha's spine, is there was one thing that could defeat her it was her past.

Gangs, Russians and even aliens were no match for the effect and dread that the mere mention of the Red Room has on her. Just thinking about it paralysed her and Anna knew this, because Anna was her best friend. Until she failed. And Failing meant punishment and punishment meant pain.

The first thing she was taught, was to look after herself and only herself, don't make ties, friends make you a fool. So when Nat started to become top of class it was no question that Anna would constantly follow a close second to her best friend, and in the red room second wasn't good enough. Tortured day and night Anna would scream her way through her 13th, 14th and 15th birthday and Nat couldn't do anything about it.

'After you became 'the best assassin ever known' I was forced into HYDRA, they had no use for me except for a lab rat. A fucking lab rat Natalia. I spent years and years of my life training and because of you, years and years of my life we're spent being tortured and tested on.'

Nat's face dropped. Being tortured by the red room was difficult enough, but HYDRA? Well, that was a whole new level. Nat only spent a few years with HYDRA until she became a payed assassin but the years she stayed she didn't enjoy. She stared at Anna, hidden in the shadows. Just like old days.

'I'm so sorry, I genuinely am. But I don't understand why you're here? Am I supposed to turn back time and stop being good?'

'Hahaha, no. You see when I was being tested on by HYDRA, one thing they tried out was a drug that could make you invincible and powerful. And it actually worked, but then a base got blown up where the drug was being manufactured and everyone who knew it's secret died. And you know what's even better? I was the only one who was given it! So Natalia Romanoff, you ready to meet your match?'

Heart rate raised, hands at the ready position, Natasha knew there was only one way to end this.

'I was born ready'

The first thing that happened was that Anna lunged at Natasha, even though she had a small body her weight pushed Romanoff over like she was a paper clip. Punch after punch was thrown in Natasha's stomach, forcing the wind out of her lungs. Gaining the upper hand she pulled out her gun and took a shot at Anna. Nothing happened, the bullet hit but she just stood there laughing and unfazed, what bought Nat back to reality was the sound of the gun clattering to the floor. Punches were thrown, kicks were blocked and it wasn't until Anna pulled out a knife that Natasha really started to worry. Anna was making her way over to the door, and inevitably locked it. There was no escape for the black widow now.

'It's kill or be killed then is it? What makes you think that you can win even with your enhancements. You know it takes a lot to kill 'little miss avenger'. Heavily breathing she took out her knife and prepared to die. It wasn't the best strategy she's ever had but she knew that for any normal person they would be dead by now. Charging at Anna knife in one hand, she kicked and struggled trying to cut her former friend, she soldiered on until she realised that the cuts that should have appeared didn't. Her skin seemed to be impenetrable.

Think, think, think! Another way to kill someone? Ahhh that's it!

Running on adrenaline, Natasha jumped from the desk onto the shoulders of the small figure and pulled out a wire from her sleeve. Using the same move as she did on Bucky but pulling with all the amount of strength and will she had. It started to work until her leg started to tingle and she felt a burning sensation coming from her thigh. This didn't matter tho, as Anna fell face first to the floor.

'Aww dammit my new suite as-well!' Natasha cursed out-loud looking at the small pool of blood forming from her leg. It was nothing that couldn't be fixed by a bandage.

Turning round to inspect the desk in which Anna was sat on was a mistake and as soon as her head moved away Anna grabbed Natasha's fallen gun.

'Hey Natalia?'

At the sound of the voice Nat turned and faced 3 incoming bullets. Due to the speed of the bullets and the reaction Time she had her chance of missing one was very low, but still she jumped. As the bullets hit her body, she was pushed backwards by the sheer force of the shot. One bullet was lodged in her shoulder, the other her stomach, the other her lung.

Menacingly, Anna approached the worlds greatest assassin and presented a knife to Widows face.

'Let's start with that lovely face shall we?'

She started by cutting her hair, then her cheek, her body was exposed and then slashed, her legs and even feet felt the wrath of an angry Russian with a knife. Blood poured out of every known place and the pain Natasha was in was the worst she's ever felt.

'Goodbye my friend' Anna whispered.
