Everyone was in the lab, assessing the damage Ultron caused. Turns out, during the fight, one of the Iron Legion sentries took Loki's scepter.

Thor went to track the Legionnaire down, Bruce and Natasha went to figure out if Ultron escaped, and if so, how.

Aaron spent the entire time glaring angrily at Tony and Bruce and tried his hardest not to knock both of their heads together in super-speed a hundred times.

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

Steve: Ultron.

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

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

Rhodey: He's in your files, he's in the Internet...what if he decides to access something a little more exciting?

Hill: Nuclear codes.

Rhodey: Nuclear codes...

Aaron glared at Tony even harder as Tony was staring at a destroyed Legionnaire the whole time.

Rhodey: Look, we need to make some calls, assuming we still can.

Natasha: (confused) Nukes? He said he wanted us dead.

Steve: He didn't say "dead", he said "extinct".

Clint: He also said he killed somebody.

Bobbi: Uh, correct me if I'm wrong, but there was nobody else besides us in the building.

Tony: Yes, there was.

He summons a hologram of JARVIS, but it was destroyed and fragmented with hints if blue surrounding it.

(A/N: Aaron is standing next to Steve, away from Tony and Bruce)

Aaron: (shocked) Oh, god...

Bruce: (shocked and confused) What?

They all stared at the hologram in shock and confusion.

Bruce: This is insane...

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

Aaron: No, Ultron could've assimilated JARVIS. This isn't strategy, this is...this is...

Bruce: Rage.

Aaron: Yeah, rage.

Suddenly, Thor came into the lab and grabbed Tony by the neck and held him up as he strangled him.

Bobbi: Whoa, whoa, whoa!

Clint: It's going around.

Tony: (while choking) (to Thor) Come on, use your words, buddy

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

Steve: Thor! The Legionnaire?

Thor let go of Tony and shoved him away.

Thor: Trail went cold about 100 miles after, but it's headed north. And it has the scepter. Now, we have to retrieve it, again!

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

Aaron: (to Tony) You got off easy, Stark. If it were me, I would've knocked both your and Bruce's heads together at Mach 5, and that's me going easy.

Steve: (turns to Aaron) You knew about this?

Aaron: I did, and I tried to talk them out of it. I didn't say anything because I thought he'd listen to me and scrap the whole idea. But, turns out, I was an idiot for thinking that Tony Stark wouldn't be a stubborn jackass.

Helen: I don't understand...(turns to Tony) You built this program. Why is it trying to kill us?

Suddenly, Tony began laughing as Bruce shook his head, silently telling that now's not the time.

Thor: You think this is funny?

Tony: (turns to Thor) No. It's probably not, right?
Is this very terrible? Is it so...(laughs) Is it so...It-It is, it's terrible.

Aaron: (walks up to Tony) You know, this shitshow wouldn't have even happened if you hadn't messed with something you didn't understand, like I told you to!

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

Bruce: Tony, Maybe this might not the time...

Tony: (turns to Bruce) Really? That's it? You just roll over and show your belly every time somebody snarls?

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

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

Steve: Well, you did something right. And you did it right here. The Avengers were supposed to be different than S.H.I.E.L.D.

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

Rhodey: (sarcastically) No, it's never come up.

Tony: Saved New York?

Aaron: (sarcastically) Never heard that one before.

Tony: Recall that? A hostile alien army came charging through a hole in space...we're standing 300 feet below it...We're the Avengers. We can bust arms dealers all the live-long day, but...(points up) That up there, that's...that's the endgame. How were you guys planning on beating that?

Steve: Together.

Tony: We'll lose.

Steve: Then we'll do that together, too.

Aaron smiles when he hears this. This is what the Avengers are supposed to be. A team willing to fight when others couldn't or wouldn't. One that sticks together through thick and thin, no matter what.

Steve: Thor's right, Ultron's calling us out. And I'd like to find him before he's ready for us.

Aaron: The world's a pretty big place. Let's start making it smaller.

Steve: He's right. Let's get to work.

Timeskip

The Avengers spent all night trying to find Ultron. Aaron decided to call it a night and slept in his room. Despite him and Bobbi having a loft of their own, Tony made him a room to stay in, just like he did for the rest of the Avengers.

Aaron quickly fell asleep, but he was met with a peculiar sight.

He found himself in a market in Sokovia for some reason.

He looked around in confusion until his eyes landed on a familiar person.

Wanda Maximoff. And she seemed to see him too, and is just as confused as Aaron is.

Wanda: (confused) What are you doing here?

Aaron: I uhh...don't think I'm actually here...Last I checked, I was in my room in New York after Skynet 2.0 decided to wake up and attack us.

Wanda seemed to understand the reference, but not because she's seen the Terminator movies, and Aaron somehow knew this.

Aaron: You met Ultron, didn't you? You and Pietro?

Wanda: Get out of my head!

Aaron: I didn't mean to get in your head to begin with! ...What did Ultron tell you?

Wanda didn't answer, but she did ask him a question.

Wanda: Why would you help Stark? You're meant to be a hero, why would you help a killer like him?

Aaron: Tony's a lot of things, but a killer isn't one of them.

Wanda: Tell that to my parents!

Aaron was confused by Wanda's accusation, but he remembered something, and put it together.

Aaron: The shell that hit your apartment building, it was a Stark Industries shell, wasn't it?

Wanda didn't answer, but that was the only answer Aaron needed.

Aaron: You and your brother want revenge, is that it? Is that what Ultron promised you?

Again, Wanda didn't answer, but it was more than enough for Aaron.

Aaron: Look, revenge won't do you or Pietro any good. It corrupts you, turns you into something you're not. Trust me, I know, I've been there.

Wanda: You don't know a damn thing!

Aaron: Maybe. But what I do know is that Ultron doesn't have your best interest at heart. He's lying to you, using you to get what he wants, you and your brother are just a means to an end, and once he gets what he wants...you'll just be loose ends to him.

Wanda: You're wrong! GET OUT OF MY HEAD!

The next morning

Aaron woke up and found himself in his room back in New York.

He looked at the clock and saw that it was 8:15 in the morning.

He sighed and got up from the bed, got dressed, and walked out.

???: Morning, Aaron.

He turns to see Steve walking towards him with a tablet in hand.

Aaron: Morning, Cap. (points to the tablet) What's that?

Steve: See for yourself.

He hands Aaron the tablet which showed a picture of Strucker, dead, and the word "PEACE" written in blood on the wall behind him.

Aaron: Jesus...

Steve: Yeah. Come on.

Steve and Aaron went into a room with the rest of the Avengers.

Steve hands Thor the tablet.

Tony: What's this?

Steve: A message. Ultron killed Strucker.

Thor pushed the tablet onto Tony's chest, who grabs it and sees what's on it.

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

Bobbi: No, this is a smoke screen. Why send a message when you've already given a speech?

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

Natasha: Yeah, I bet that he...

She types into the computer to look for what they have in Strucker, but...

Natasha: Yep. Everything we have on Strucker's been erased.

Aaron: (grins) Not everything.

He speeds out of the room and comes back with a large pile of physical files and sets them on the table before speeding back out and coming back with another pile and setting those down.

Aaron: Paper. Old, but gold.

The Avengers began digging into the files for any leads.

Clint: Known associates...Strucker had a lot of friends.

Bobbi: All horrible people, some with crappy names. Like, who the hell calls himself "claw"?

Tony: Wait, I know that guy. Give me that.

Bobbi hands Tony the file she had on a man named Ulysses Klaue.

Tony: Back in the day, he operates off the African coast, black market arms.

Steve looked at Tony in disappointment, but Tony cleared things up.

Tony: There are conventions, right. You meet people, I didn't sell him anything. He was talking about finding something new, a game changer. He was very Ahab.

Thor noticed something that resembled a scar on Klaue's neck.

Thor: (points at the scar) This.

Tony: This is a tattoo, I don't think he had it.

Thor: No, (points to Klaue's tattoo on his neck) those are tattoos, this is a brand.

Bruce scans the brand on the computer.

Bruce: Yeah, it's a word in an African dialect meaning "thief" in a much less friendly way.

Aaron: What dialect?

Bruce: Wakanada...(looks at the screen) Wa-Wa-Wakanda.

Tony and Steve look at each other as they have realized what Klaue stole.

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

Steve: I thought your father said he had the last of it.

Bobbi: I'm don't think I understand, what comes out of Wakanda?

Tony, Steve, and Aaron look at the shield.

Tony: The strongest metal on Earth.

Steve: (turns to Tony) Where is this guy now?

Aaron: Uhhh, according to those files, he's in South Africa.

Steve: Alright, let's move.

The Avengers left the room, suited up, and boarded the quinjet before flying to South Africa.

Timeskip
South Africa

The Avengers arrived at a salvage yard. Bruce stayed on the quinjet until it was time for a "code green".

Tony, Aaron, Thor, and Steve would confront Ultron while Clint, Natasha, and Bobbi would sneak around.

They went inside and saw Ultron, in a bigger metal body, ranting to himself about one of his creators.

Ultron: It's a thing with me. Stark is...he's a sickness!

Tony: Ah, Junior...

Ultron turns to see Tony, Aaron, Steve, and Thor behind him.

Tony: You're gonna break your old man's heart.

(A/N: Aaron is between Thor and Tony)

Ultron: If I have to.

Wanda and Pietro stand of either side of Ultron, with Wanda staring at Aaron a bit longer.

Thor: (To Ultron) Nobody has to break anything.

Ultron: Clearly, you've never made an omlette.

Tony: (turns to Thor) He beat me by one second.

Pietro: (to Tony) Ah, this is funny, Mr. Stark. It's what, comfortable? Like old times.

Aaron and Tony followed Pietro's gaze and saw several rockets with the Stark Industries logo painted on them.

Tony: This was never my life.

Aaron: (to the twins) Look, you two are walking down a dangerous path, but you can still walk away from all this.

Wanda: Oh, we will.

Steve: I know you've suffered...

Ultron: (groans in disgust then chuckles) Captain America, God's righteous man, pretending you could live without a war. (turns to Aaron) And The Flash, a symbol of hope to many, but also a killing curse to anyone he touches. I can't physically throw up in my mouth, but...

Aaron: If you really knew me, you'd know I never killed anyone, and I never will.

Ultron: I'm certain your father Brian O'Connor and Ethan Phillips would beg to differ.

Aaron inhales sharply as he clenched his hands into fists in anger.

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

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

Tony: Uh-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...

He suddenly activated a magnet in his hand to pull Tony closer before firing a blast to send him back. Tony flew at Ultron and began fighting him as the rest of the Avengers fought the Ultron bots that showed up.

Pietro charged at Thor and pushed him back a few feet. He looked at Aaron and shook his head as he ran off somewhere else.

Steve tried to charge at Wanda, but she used her psionic energy to push him back.

Suddenly, gunfire was heard as Klaue's crew attacked them with guns.

Bobbi took out her batons and took out three goons before throwing one of the batons at the fourth, knocking him out.

Clint began shooting his arrows at the goons.

Aaron dealt with some of the Ultron bots when he saw Pietro running towards Steve. He intercepted him and pushed him away a few feet. Pietro got up quickly.

Pietro: Nope, not doing that again.

He tried to speed away, but Aaron blocked him off.

Pietro: Okay, then.

He swings his fist at Aaron, who easily parries the swing. Pietro swung again, but Aaron grabbed him arm and threw Pietro over his shoulder and onto the ground hard.

Aaron: Stay down, buddy.

Meanwhile

Wanda was standing next to an Ultron bot when it turned to her and its blue light changed to red and spoke in Ultron's voice.

Ultron: It's time for some mind games.

Its light changed back to blue and charged towards the Avengers.

Meanwhile

Back on the quinjet, Bruce was feeling uneasy, so he tried contacting the team.

Bruce: Guys, is this a "code green"?

All he got was scrambled noises. Taking this as a bad sign, Bruce opened the ramp and walked down it as he heard gunshots from the shipyard.

Meanwhile

Aaron was dealing with two more Ultron bots.

Steve: (on comms) Thor, status?

Thor: (on comms) The girl tried to warp my mind. Take special care, I doubt a human can keep her at bay...

Aaron: (into his comms) Thor?

He received no response as he saw Pietro speed in and take a fighting stance in front of him.

Aaron: (sighs) Come on, Pietro, you know I'll just kick your ass again, right? I did it twice already.

Pietro: (smirks) Yeah, I know.

Aaron: (confused) Then why are you-?

His eyes widen when he realized what Pietro was doing.

He was distracting him.

He turns around, only to be met by Wanda, who uses her powers to manipulate his mind...

???

Aaron was in a barren desert. He looked around in confusion.

Aaron: HELLO?!

His voice echoes across the desert, but there was no response.

Aaron: ANYBODY?!

???: Don't bother.

Aaron turns towards the voice, and his eyes widen in shock when he sees who it is.

Brian: No one's coming to help you.

Aaron: (shocked) Dad?

Brian: No one's gonna help you, just like you didn't help me.

???: Or me.

Aaron turns to see someone else he never thought he'd see again.

Ethan: I don't know why the hell did I choose to trust you, but doing that got me killed.

Aaron looked down and saw blood coming out of the left side of Ethan's chest...exactly where he shot himself.

He then turned to his father and saw three smoking blades protruding out of his chest...exactly where he got stabbed by Viktor Phillips.

Brian: You're a goddamn curse to anyone who even thinks of coming anywhere near you.

Ethan: You call yourself a hero, but all you do is get people killed.

Aaron: (tearing up) No...no, I tried to save you...I swear to God, I tried to save you both.

???: Like you "tried" to save me?

Aaron turns to see someone wearing a suit, and his eyes widen when he recognized who it was.

Coulson: You just left me to die.

Aaron: (shocked) Coulson, I...

Coulson: And now, everyone you ever gave a damn about will suffer the same fate as us.

Suddenly, several gravestones surrounded Aaron, who was even more shocked, and even terrified when he read the names on them...

Mia O'Connor
Barbara Morse
James de Luca
Gwen Stacy
George Stacy
Tony Stark
Steve Rogers
Natasha Romanoff
Thor Odinson
Clint Barton
Bruce Banner
Nicholas J. Fury

Aaron started hyperventilating as he several more gravestones filled the desert, most with names Aaron didn't recognize.

Brian: And eventually, so will the world...

Aaron dropped his to his knees and held his head as an overwhelming pain filled his head. Soon, the pain became too much, causing him to let out a bloodcurdling scream...

Aaron...

Aaron...

South Africa

???: AARON!

Aaron opened his eyes and immediately got up and ran into the wall, not seeing who was it that woke him up as he was breathing heavily.

He found himself back at the shipyard.

He finally saw Clint and Bobbi in front of him. Clint was helping Natasha, who seemed to be in a trance.

But Aaron couldn't calm down.

Bobbi started walking towards Aaron.

Bobbi: Aaron...

Aaron: STAY BACK!!! STAY AWAY FROM ME!!!

Bobbi and Clint were taken aback by Aaron's sudden outburst.

Clint: Okay, kid. We need to get to the quinjet. Everyone else is down, and we need to get out of here.

Aaron nods before joining Clint, Natasha, and Bobbi.  Bobbi kept looking at Aaron, who seemed to be in a worse state than everyone else combined.

Timeskip

The Avengers were in a quinjet with Clint piloting it, and morale was very low.

Turns out, after mind-fucking most of the Avengers, Wanda manipulated Bruce into turning into the Hulk and going on a rampage in Johannesburg, forcing Tony to call in the Hulkbuster armor and dealing with Bruce, but not without causing extensive damage to the city.

Ultron and the Maximoff twins manage to escape with a substantial amount of vibranium.

Bruce was in the middle of the quinjet, covering himself with a blanket.

Aaron was in the back of the quinjet, isolating himself from everyone else.

Bobbi kept glancing at Aaron, and her heart broke every time she did. She hated seeing the man she loves so broken. She desperately wants to console him, but he pushed her away every time she tried.

Hill: (on comms) The news is loving you, guys. Nobody else is. There's been no official call for Banner's arrest, but it's in the air.

Tony: (into his comms) Stark Relief Foundation?

Hill: (on comms) Already on the scene...How's the team?

Tony: (into his comms) Everyone's...We took a hit. We'll shake it off.

Hill: (on comms) Well, for now, I'd stay in stealth mode, and stay away from here.

Tony: (into his comms) So, run and hide?

Hill: (on comms) Until we can find Ultron, I don't have anything else to offer.

Tony: (into his comms) Neither do we.

He ends the transmission and walks up to Bobbi.

Tony: How's Aaron doing?

Bobbi: (sighs) He's gotten a little better, but...Whatever he's seen must've been bad, because, even now, I've never seen him like this since...

Tony: Since his dad...

Bobbi: Yeah, but somehow, this is worse...a lot worse than that.

Tony nods in silence.

Bobbi: (angrily) I swear to God, next time I see that Maximoff bitch, she's gonna be begging me for mercy.

Tony didn't have anything to say about that, so he walked away and went to Clint.

Tony: Hey, wanna switch out?

Clint: No, I'm good. (looks at Bobbi) You know, I've never seen Bobbi this angry, or angry at all...

Tony: (surprised) Really?

Clint: Yeah, she isn't really an angry person, so...if she's pissed off like that...That Maximoff girl's gonna rue the day she pissed off Bobbi Morse.

Tony: (chuckles) Yeah...

Clint: ...If you wanna get some kip, now's a good time, cause we're still a few hours out.

Tony: A few hours from...where?

Clint: A safe house.

Tony stayed silent as Clint continued flying the quinjet to the "safe house."
