We see Ultron has uploaded his consciousness in the abandoned Sokovia base.

The Avengers are gathered in the lab

Bruce Banner:
All our work is gone. Ultron cleared out, used the internet as an escape hatch.

Steve Rogers:
Ultron.

Natasha Romanoff:
He's been in everything. Files, surveillance.

Regulus:
Probably knows more about us than we know about each other.

James Rhodes:
He's in your files, he's in the internet. What if he decides to access something a little more exciting?

Maria Hill:
Nuclear codes.

The ones who knew what nuclear meant paled at the thought

James Rhodes:
Nuclear codes. Look, we need to make some calls, assuming we still can.

Natasha Romanoff:
Nukes? He said he wanted us dead.

Steve Rogers:
He didn't say dead. He said extinct.

Clint Barton:
He also said he killed somebody.

Maria Hill:
But there wasn't anyone else in the building.

Tony Stark:
Yes there was.

Stark bring up the now-destroyed 3D image of JARVIS' consciousness

Tony frowned at the sight of his beloved ai.

Bruce Banner:
This is insane.

Steve Rogers:
JARVIS was the first line of defense. He would've shut Ultron down, it makes sense.

Bruce Banner:
No, Ultron could've assimilated Jarvis. This isn't strategy, this is...rage.

Thor barges in and grabs hold of Stark by his throat, holding him up

Regulus:
Thor!

Reggie looks at Thor with a tight smile. "Thor. You oversized golden retriever." Thor looks at him with acknowledgement. "We don't grab people by the neck, especially ones that have no sort of protection or are basic baseline human." He says. Thor realizes what he means and shoots Tony a sorry look.

Tony subconsciously rubs his neck.

Clint Barton:
Woah, woah, woah! It's going around.

Tony Stark:
[to Thor]
Come on. Use your words, buddy.

Thor:
I have more than enough words to describe you, Stark.

Steve Rogers:
Thor! The Legionnaire.

Thor lets go of Stark

Thor:
Trail went cold about a hundred miles out but it's headed north, and it has the scepter. Now we have to retrieve it, again.

Natasha Romanoff:
The genie's out of that bottle. Clear and present is Ultron.

Dr. Helen Cho:
I don't understand. You built this program. Why is it trying to kill us?

Stark starts laughing, Banner subtly shakes his head at him to get him to stop

"The bloody hell are you laughing about." asked James, who looked at him with anger. Sirius goes to agree. Tony rolls his eyes, not seeming to care.

Reggie stares daggers at James. He remembers that the last encounter he had with James was not very fun.

Thor:
You think this is funny?

Tony Stark:
No. It's probably not, right? Is this very terrible? Is it so... is it so... it is. It's so terrible.

Thor:
This could've been avoided if you hadn't played with something you don't understand.

Tony Stark:
No, I'm sorry. I'm sorry. It is funny. It's a hoot that you don't get why we need this.

Bruce Banner:
Tony, maybe this might not be the time to--

Tony Stark:
Really?! That's it? You just roll over, show your belly, every time somebody snarls.

Bruce Banner:
Only when I've created a murder bot.

Tony Stark:
We didn't. We weren't even close. Were we close to an interface?

Steve Rogers:
Well, you did something right. And you did it right here. The Avengers were supposed to be different than SHIELD.

Tony Stark:
Anybody remember when I carried a nuke through a wormhole?

James Rhodes:
No, it's never come up.

Tony Stark:
Saved New York?

James Rhodes:
Never heard that.

Tony Stark:
Recall that? A hostile alien army came charging through a hole in space. We're standing three hundred feet below it. We're the Avengers. We can bust arms dealers all the live long day, but, that up there? That's... that's the end game.

Reggie lets out a shaky breath. Remembering everything that happened that day. How it screwed everyone over. Then he remembers Tony's death. Things may be different now, but it didn't change what happened five years ago.

He sees how Pepper struggles to raise Morgan alone.

Clint still has his moments thinking about Natasha.

How Bucky still has his nightmares.

He remembers Natasha.

He remembers the war.

Tony Stark:
How were you guys planning on beating that?

Steve Rogers:
Together.

Tony Stark:
We'll lose.

Steve Rogers:

Reggie can't help but think about what Tony said after returning from space.

Stark looks at him for a moment before turning away

Steve Rogers:
Thor's right. Ultron's calling us out. And I'd like to find him before he's ready for us. The world's a big place. Let's start making it smaller.

Back in Sokovia, the twins meet with Ultron in an empty church.

James cringes at his look alike.

Wanda Maximoff:
Talk. And if you are wasting our time...

Ultron:
Did you know this church is in the exact center of the city? The elders decreed it so that everyone could be equally close to God. I like that. The geometry of belief.

Ultron is sat in a chair facing away from them, a cloth draped over him

Ultron:
You're wondering why you can't look inside my head.

Wanda Maximoff:
Sometimes it's hard. But sooner or later, every man shows himself.

Ultron stands and faces them, revealing his new body. Wanda briefly looks shocked

Ultron:
Oh, I'm sure they do. But you needed something more than a man. That's why you let Stark take the scepter.

Wanda Maximoff:
I didn't expect... But I saw Stark's fear, I knew it would control him, make him self-destruct.

Some glared at Wanda. Tony couldn't help but feel uncomfortable near said girl.

Ultron:
Everyone creates the thing they dread. Men of peace create engines of war, invaders create avengers, people create...smaller people? Uh...children! I lost the word there. Children. Designed to supplant them, to help them...end.

Wanda Maximoff:
Is that why you've come? To end the Avengers?

Ultron:
I've come to save the world. But also... yeah.

[In the Sokovia base.]

We'll move out right away. This is a start, but there's something we need to begin the real work.

Wanda Maximoff:
[referring to Ultron's bots]
All of these are...

Ultron:
Me. I have what the Avengers never will. Harmony. They're discordant, disconnected. Stark's already got them turning on each other. And when you get inside the rest of their heads...

The Avengers couldn't help but wince at the truth. Except for a few induvesula, they weren't really connected.

Pietro Maximoff:
Everyone's plan is not to kill them.

Ultron:
And make them martyrs? You need patience. Need to see the big picture.

Pietro Maximoff:
I don't see the big picture, I have a little picture. I take it out and look at it every day.

Ultron:
You lost your parents in the bombings. I've seen the records.

Pietro Maximoff:
The records are not the picture.

Wanda Maximoff:
Pietro.

Ultron:
No, please.

Pietro Maximoff:
We were ten years old, having dinner, the four of us. When the first shell hits, two floors below, it makes a hole in the floor. It's big. Our parents go in, and the whole building starts coming apart. I grab her, roll under the bed and the second shell hits. But, it doesn't go off. It just... sits there in the rubble, three feet from our faces. And on the side of the shell is painted one word...

Wanda Maximoff:
Stark.

Pietro Maximoff:
We were trapped for two days.

Wanda stared at the screen with hatred. She still has a slight burning hatred for Stark. She'd never say it out loud because she was afraid of losing Reggie. He was the last person who truly cared for her. She wasn't going to let Stark take him away from her.

Tony couldn't help but feel disgusted. He knew his bombs had destroyed many lives. He wished he would have gotten rid of them sooner. A thought hit him. They never sold bombs to the Sokiva army. Weird. 

The wizards looked at Tony with disgust and hatred. They'd never understand the muggle world and yet they judge them so harshly.

Wanda Maximoff:
Every effort to save us, every shift in the bricks, I think, "This will set it off." We wait for two days for Tony Stark to kill us.

Pietro Maximoff:
I know what they are.

Ultron:
I wondered why only you two survived Strucker's experiments. Now I don't. We will make it right.
[to Pietro]
You and I can hurt them.
[to Wanda]
But you will tear them apart, from the inside.

Many shuddered in fear.

Back at the Avengers headquarters]

Maria Hill:
He's all over the globe. Robotics labs, weapons facilities, jet propulsion labs, reports of a metal man, or men, coming in and emptying the place.

Steve Rogers:
Fatalities?

Maria Hill:
Only when engaged. Mostly guys left in a fugue state going on about old memories, worst fears, and something too fast to see.

Steve Rogers:
Maximoffs. Well, that makes sense he'd go to them, they have someone in common.

Maria Hill:
Not anymore.

She hands Steve a tablet showing photo of Strucker's dead body with the word PEACE written in blood on the wall next to him

Clint Barton:
[Barton's talking on his cell phone]
That's a negative. I answer to you. Yes, ma'am.

Steve interrupts him

Steve Rogers:
Barton, we might have something.

Clint Barton:
Gotta go.

Steve Rogers:
Who was that?

Clint Barton:
Girlfriend.

"You have a girlfriend." Steved asked. Nat and Reggie smiled. Clint only nods with an awkward smile.

After Steve has gathered the rest of the team he shows them the photo of Strucker's body

Tony Stark:

Steve Rogers:
A message. Ultron killed Strucker.

Tony Stark:
And he did a Banksy at the crime scene, just for us.

Natasha Romanoff:
This is a smokescreen. Why send a message when you've just given a speech?

Steve Rogers:
Strucker knew something that Ultron wanted us to miss.

Regulus:
Yeah, I bet he...
[looks at the computer monitor]
Yep. Everything we had on Strucker has been erased.

Tony Stark:
Not everything.

The team go through the physical files they have on Strucker

Steve Rogers:
Known associates. Well, Strucker had a lot of friends.

Bruce Banner:
Well, these people are all horrible.

Tony Stark:
Wait. I know that guy.

Some look at Tony with accusing faces.

Banner passes him the photo he was looking at

Tony Stark:
From back in the day. He operates off the African coast, black market arms.

Steve gives him an accusing look

Reggie looks at Steve with a pointed look and says, "You seem to forget your dear old friend Hoawrd used to do worse,"  not caring for Tony's annoyed face at the mention of his father. Steve looked almost offended at the rude comment about his friend. "Howard was a go-" he was cut off by Reggie. "Shut up"

Tony Stark:
There are conventions, alright? You meet people, I didn't sell him anything.
[we see the photo is of a man named Ulysses Klaue]
He was talking about finding something new, a game changer, it was all very "Ahab."

Thor:
[Thor points to the scar on the back of Klaue's neck]
What's this?

Tony Stark:
Uh, it's a tattoo. I don't think he had it...

Thor:
No, those are tattoos, this is a brand.

Bruce Banner:
[Banner identifies the brand on Klaue's neck on the computer]
Oh, yeah. It's a word in an African dialect meaning thief, in a much less friendly way.

Steve Rogers:
What dialect?

Bruce Banner:
Wakanada...? Wa...Wa...Wakanda.

Reggie begins to cheer at the mention of Wakanda. Everyone looks confused. "Best people you'll ever meet." he says to everyone in confusion.

Tony Stark:
If this guy got out of Wakanda with some of their trade goods...

Steve Rogers:
I thought your father said he got the last of it?

Reggie giggles in his seat.

Bruce Banner:
I don't follow. What comes out of Wakanda?

Tony Stark:
[looking at Steve's shield]
The strongest metal on earth.

Dumbledore looked intrigued at that.

Steve Rogers:
[to Stark]
Where is this guy now?

Salvage Yard, African Coast; Klaue is talking on the phone in his office

Ulysses Klaue:
Don't tell me your man swindled you. I sent you six short range heat seekers and got a boat full of rusted parts. Now, you will make it right, or the next missile I send you will come very much faster.
[he ends the call and connects to another call]
Now, minister, where were we?
[suddenly the lights go out causing a commotion in the salvage yard. The twins enter Klaue's office]
Yeah. The enhanced. Strucker's prize pupils.
[picks up a dish of candies from his desk]
Want a candy? Oh, sorry to hear about Strucker. But then, he knew what kind of world he was helping create. Human life, not a growth market.
[the twins look at each other]
You...you didn't know? Is this your first time intimidating someone? I'm afraid that I'm not that afraid.

Wanda Maximoff:
Everybody's afraid of something.

Ulysses Klaue:
Cuttlefish. Deep sea fish. They make lights. disco lights. Whoom, whoom, whoom! to hypnotize their prey, then whoom! I saw a documentary, it was terrifying.

As if on cue, Ultron breaks through the glass window and knocks down Klaue

Ultron:
There is no "man" in charge. Let's talk business.
[Klaue gives Ultron some vibranium from his stash]
Upon this rock I will build my church. Vibranium.

Ulysses Klaue:
You know, it came at great personal cost. It's worth billions.

Ultron chuckles and remotely puts money in Klaue's bank account

Ultron:
Now, so are you. It's all under your dummy holdings? Finance is so weird. But I always say, "Keep your friends rich and your enemies rich, and wait to find out which is which."

Ulysses Klaue:
Stark.

Ultron:
What?

Ulysses Klaue:
Tony Stark used to say that...to me. You're one of his.

"Probably should have not said that" says Reggie

Ultron:
What?! I'm not...!
[he grabs Klaue]
I'm not. You think I'm one of Stark's puppets, his hollow men? I mean look at me, do I look like Iron Man? Stark is

He chops off Klaue's arm

There are gasps of shock heard throughout the hall.

Ultron:
I'm sorry. I am sor-- Ooh, I'm sure that's going to be okay. I'm sorry, it's just I don't understand. Don't compare me with Stark! It's a thing with me. Stark is, he's a sickness!

Some people look at the screen in disgust or fear.

Stark appears in his Iron Man suit

Tony Stark:
Ahh, Junior.
[He lands, and Thor and Steve come up behind him]
You're gonna break your old man's heart.

Ultron:
If I have to.

Thor:
We don't have to break anything.

Ultron:
Clearly you've never made an omelet.

Tony Stark:
He beat me by one second.

Pietro Maximoff:
Ah, this is funny, Mr. Stark. It's what, comfortable? Like old times?

Tony Stark:
This was never my life.

Steve Rogers:
[to the twins]
You two can still walk away from this.

Wanda Maximoff:
Oh, we will.

"I mean period.." says Mary

Steve Rogers:
I know you've suffered.

Ultron:
Uuughh! Captain America. God's righteous man, pretending you could live without a war. I can't physically throw up in my mouth, but...

Thor:
If you believe in peace, then let us keep it.

Ultron:
I think you're confusing peace with quiet.

Tony Stark:
Yuh-huh. What's the Vibranium for?

Ultron:
I'm glad you asked that, because I wanted to take this time to explain my evil plan--

Ultron attacks Stark, and his drones drop down to attack Steve and Thor. The Twins join the fight.

Everyone begins to tense, sensing fights about to begin.

Ulysses Klaue:
[as everyone else fights]
Shoot them!

Klaue's Mercenary:
Which ones?

Ulysses Klaue:
All of them!

Klaue's Mercenary:
[to his men]
Move, move, move!

The rest of the team, including Natasha, Barton and Regulus now battle it out with Ultron's drones, Klaue's men, and the twins as Stark fights with Ultron

Steve Rogers:
[after knocking down Pietro]
Stay down, kid!

Wanda cringes at that. She was not a child. She was a grown women.

Ultron:
[through a drone, to Wanda]
It's time for some mind games.

Banner hears the commotion as he waits in the Quinjet

Bruce Banner:
Guys, is this a Code Green?

Wanda and Reggie both tens up as they realize
