(a/n) Hey guys here is chapter 4. This is the party and introduction of Ultron. I will be writing this different from the film. So I am taking the party in my own direction. So don't be surprised when it does not match AoU.

It has been a few days since the Sokovia mission. Steve never came to talk to Nat and Nat never went and tried to talk to Steve. He has been non-stop training since the mission ended. Nat on the other hand has been taking a break which is totally uncharacteristic of her. Tonight is the first time they will be in the same room since the debriefing after the mission. Nat is not sure how things will go down. She is also not sure why Steve never tried to talk to her like they planned. Maybe he decided against it. Who knows.

Nat is just hanging out on the couch sipping on her beer when Steve approaches her and takes a seat.

"Hey Nat. Sorry I haven't had the chance to stop by your floor and chat. I have had a lot on my mind and needed to just think. I went to visit Peggy the day after we got back from the mission. She isn't doing too well. They don't know how much longer she will be with us." Steve pauses. "Sorry bothering you with this but I just needed someone to talk too. I know that I have you and the rest of the team but Peg is the last person from before I went down with the plane that is still living. It is scary to know that I will lose her too and I feel like I will be alone. Like no one understands me because they aren't from that time." Steve finishes and looks to Natasha for a response.

Natasha isn't sure how to respond to that. She knows that she is from his time and could be that to him. But at the same time how will he look at her once he knows she has been lying all this time? Will he be okay with it or will he be unable to accept her for who she really is?

"Steve, I can't even begin to imagine how you are feeling but I can and will be there for you through all of this. Can we talk in private, maybe up on my floor? There is something I would like to share with you." Nat tells him with a hesitant tone.

"Sure Nat lets go"

As the head up to her floor, Natasha wonders if this is a major mistake or if she is doing the right thing. It would be nice to have someone to know she thinks. In all honesty everyone from her past is deceased now as well. Well at least anyone that she can think of.

" we have reached your floor, do you need anything else from me?" J.A.R.V.I.S. asks.

"Yes, please shut down any monitoring devices that Tony has on this floor that is going to pick up anything that is said. What I am about to say is for Steve's ears only so please make sure Tony does not have a way to find out."

"Roger that Agent Romanoff"

" Thank you J.A.R.V.I.S." Natasha replies and then directs her attention to Steve. "There is something that you should know about me Steve." She pauses and looks into his beautiful blue eyes. He seems intent on listening so she continues "My name is Natalia Alianovna Romanova, I was born in Stalingrad, Russia. Formerly known as the U.S.S.R., I do not know my exact birth date but I am well aware of the year" Steve cuts her off.

"Nat, I know all of this what are you trying to tell me" Steve asks curiously.

"I was just getting there. My birth year was doctored by the KGB to not alert the United States as to what Russia had accomplished. My true year of birth is actually 1928. Nick kept my doctored birthdate in S.H.E.I.L.D. systems as he felt it was need to know. Clint doesn't even know. Not my birth year and not what I am about to tell you next." Natasha pauses and Steve looks at her to continue. "If you are wondering why I look so young, well it's the same reason you look so young. I was given a variant of your super soldier serum. It was nowhere near as successful as yours but I have increased healing abilities, strength, agility, and so much more just like you. My aging is also slowed significantly." Natasha stops and waits for his reply. Steve stares at her, he looks like he is studying her intently.

"Wow Nat, you don't look a day over 60" Steve replies jokingly. Nat lets him joke since she does pick on his age on the daily. Steve continues on a more serious note "Nat all joking aside, why did you choose to share this information with me so freely? You never open up?"

"Well Steve, I guess I realized that sometimes keeping my secrets is not always the best policy. There are still things that weren't released in the file dump last year that I may choose to never repeat. But I knew that this was something that could help you through your hardships with not having anyone from before the ice to talk to. I may not have known you then but I was alive and kicking back then and I am here for you now. So if you need to talk don't hesitate."

"Thanks Natasha. It really means more than you will ever know."

"Roger that Captain. I warn you. If. You. Ever. Speak. A. Word. to Stark. I will find a way to kill you slowly" Natasha mock threatens.

"Nat. I would never. I have to tell you that I…." Steve is cut off by the HQ's emergency alarm.

Natasha is sitting on her lounge waiting for what Steve is about to tell her when the alarm sounds which is odd because J.A.R.V.I.S. should have made them aware of a threat. Natasha springs into action before Steve can finish his statement. Which Natasha thinks is something she is not and may not ever be ready to hear from him.

"Steve that's odd. The alarm sounded but J.A.R.V.I.S. has not briefed us on anything. We should head back down to the team and see what's up"

"We need to make a stop at my floor so I can grab my shield"

"Okay let's go"

As Natasha is riding in the elevator with Steve, she can't help to wonder what could possibly be going on that J.A.R.V.I.S. wouldn't prep them on.

Steve hops off the elevator quickly at his floor grabs his shield and they are on their way to the common floor where the party was being held. They step off on the elevator to witness the team being accosted by a half broken down talking robot.

Natasha can't help but think to herself what the hell has Tony done now. This has to be one of his little pet projects.

As Steve and Nat are stepping off the elevator in combat mode, the robot turns to them.

"Ahhhh. Agent Romanoff and Captain Rogers, how nice of you to join the team. I was just explaining how your friends here cannot be worthy, because you are all killers. Sadly I have already had to kill today. Whoever he was, he seemed to be a good guy but I had do it. Because sometimes we are faced with ugly choices"

"Who did you kill" asks Steve who is readying for a fight.

"Not sure. But I can tell you I am Ultron. I am here on one mission and one mission only. To ensure peace in this world at this time" Ultron tells the team.

With that Tony's arsenal of "peacekeeping" robots blast through the doors and attack the team. Steve takes the first one easily ripping it to shreds. Nat takes off after another one. She is able to destroy it quickly thanks to the pistols she grabbed on the way down.

What the fuck is going on here. How the hell did this happen? Where did Ultron come from. All questions running through Nats brain as she begins fighting yet another robot. She looks to her left and Thor is taking down two at a time with Mjolnir. Steve is currently above their heads taking one down that was attempting to fly away. Nat doesn't see Rhodes anywhere, Hill is taking cover behind the sofa and taking shots at any robots that come into range, Tony is making his way to his suits, Bruce is somewhere hopefully not turning green, Clint is on a perch knocking arrow after arrow into the sorry suckers. The question is where did this Ultron go? She doesn't see him anywhere. She takes her last robot down and calls out to the team "Has anyone seen this Ultron? He is worth finding we cannot allow him to get away."

"Nat we're good here, try and find him. I'll be right behind you" Steve shouts to her.

"You got it Soldier" she yells back.

Nat takes off through the building to try and find Ultron. When it comes to her that he is probably after Loki's scepter. So she makes her way to Tony and Bruce's lab to secure it. But by the time she gets there Ultron is already removing it from its case.

"Shit" Natasha mutters.

"Ah. Agent Romanoff how nice of you to join me. Here I thought that I would get away easily. Tell me is there anyone right behind you" Ultron asks.

With that Natasha springs into action and dives for the scepter. Somehow Ultron was able to get the jump on her and blast her with enough power to kill a non enhanced human. Thankfully for Nat, he merely gave her stun. She is still conscious and tries to get up but Ultron is able to fly out of the sky light without any more resistance from the Avengers.

"Mother fucker" Natasha screams.

At that moment Steve comes running in with Thor not that far behind

"Natasha are you okay" Steve asks worried by her angered scream

"I am fine Steve but Ultron escaped with the scepter."

"It's okay Nat all that matters is that you as well as the rest of the team are okay. We got the scepter back before and we will do it again don't worry" Steve reassures her.

" I know Steve but I should have been able to stop him. He got the jump on me"

"Lady Natasha things of this nature happen do not be discouraged" Thor chimes in.

"Yeah Nat. Thor is right. We are a team and we will get it back together. Everyone makes mistakes or can't always get it done the perfect way. Look at me I am living proof. I crashed plane into the ice and was frozen for years. Now that's a major flaw in the plan" Steve tells her with a smile.

"Don't ever joke about your situation Steve. But I know where you are coming from. Just let an Agent be pissed that she didn't complete her mission okay Steve" Nat tells him

"You got it Nat. Now let's go and form a game plan with Tony. Who is cleaning up the robot mess in the common room." Steve tells her and then looks at Thor and says "You coming too? We could use your help"

"Yes, I will help Son of Rogers."

"Thanks, Thor" Steve says with a smile.

Natasha cannot believe she let Ultron get away that easily. She should have at least been able to give him a good fight, instead he hit her with one energy blast and was able to fly away. How could she let this happen. All Nat know is, she will not stop until Ultron is taken out. Now time to figure out how she can do that.
