[We cut to a cabin in the woods, at the bank of a lake. We see Tony Stark sitting outside what looks like a tiny shed.
Tony: [Clapping his hand in a famous beat. Clap! Clap! Clap-Clap-Clap! Clap-Clap-Clap- Clap!] Chow time! Maguna? Morgan H. Stark. You want some lunch?
Morgan: Define lunch or be disintegrated. [She puts on a silver and blue helmet similar to Iron Man's]
(A girl with long dark hair walks out in front of Tony. This is Morgan Stark, Tony and Pepper's daughter. She looks to be about 8 years of age.)
Tony: Okay, You should not be wearing that, okay? That is part of a special anniversary gift I'm making for Mom. (Takes the helmet off Morgan's head. She emerges out smiling mischievously.)
Morgan: Okay dad, i wanted to try it on
Tony: There you go. Are you thinking about lunch? I can give you a handful of crickets on a bed of lettuce.
Morgan: No.
Tony: That's what you want. How did you find this?
Morgan: Garage.
Tony: Really? Were you looking for it?
Morgan: No. I was looking for my ball and i found it sitting there
Tony: You like going to the garage, huh? So does daddy. It's fine, actually. Your mom never wears anything I buy her.
(They start walking towards the house, but Tony notices a black Audi pulling coming to a stop a few meters away. Steve, Nat, and Scott get out of the car. Tony sighs. He is not looking forward to the discussion about to take place.)
Scott: (Cut to after Scott's plan has been explained to Tony) Now, we know what it sounds like...
Steve: Tony, after everything you've seen, is anything really impossible?
Tony: Quantum fluctuation messes with the Planck Scale, which then triggers the Deutsch Proposition. Can we agree on that?
(Scott, Steve and Nat all look puzzled. Science is barely any of their fields.)
Steve: (Tony giving a drink to him.) Thank you.
Tony: In Layman's terms, it means you're not coming home.
Scott: I did.
Tony: No, you accidentally survived. It's a billion to one cosmic fluke. And now you wanna pull off a... What do you call it?
Scott: (Trying to hide his pride) A time heist?
Tony: Yeah, a time heist. Of course, why didn't we think of this before? Oh, because it's laughable? Because it's a pipedream?
Scott: The Stones are in the past. We can go back and get them.
Nat: We can snap our own fingers. We can bring everyone back.
Tony: Or screw it up worse than he already has, right?
Steve: I don't believe we would.
Tony: Gotta say, sometimes I miss that giddy optimism. However, high hopes won't help if there's no logical, tangible way for me to safely execute said time heist. I believe the most likely outcome would be our collective demise.
Scott: Not if we strictly follow the rules of time travel. That means no talking to our past selves, no betting on sporting events -
Tony: I'm gonna stop you right there, Scott. Are you seriously telling me that your plan to save the universe is based on Back To The Future?
Scott: [embarrassed] No.
Tony: Good. You had me worried there. 'Cause that'd be horse shit. That's not how quantum physics works.
Nat: Tony... We have to take a stand, you werent even there when we were fighting thanos, we all risked our lives to save y/n but in the end thanos still won
Tony: i wanted to be there but i was looking out for my family
Steve: y/n used to be your family at one point but you hated her, for all her life, i want to bring her home tony, i want to bring everyone home, wanda, bucky and everyone else we lost 5 years ago
Scott: look tony, can i call you tony. I know you got a lot on the line. You got a wife, a daughter. But I lost someone very important to me. A lot of people did. [His voice gets louder as he tries to sell his desperation to Tony.] And now, now we have a chance to bring her back. To bring everyone back. And you're telling me that won't even...
Tony: That's right, Scott, I won't even. I got a kid.
Steve: I HAVE A KID TOO TONY, SHES BEEN GONE FOR FIVE YEARS ALL BECAUSE WE COULDNT GET THE STONES TO GET WANDA AND BUCKY BACK. TRY LEAVING WITHOUT SEEING YOUR ONE TRUE LOVE, IMAGINE IF PEPPER GOT BLIPPED HOW YOU WOULD FEEL
Tony: honestly steve im sorry, do know whats it like, remember i lost pepper because of one problem so i do know whats it like, now lower your voice my daughter is inside
[Morgan runs to her dad, who picks her up.]
Morgan: Mum told me to come and save you.
Tony: Good job. I'm saved. [Turning to face Cap, Nat and Scott.] I wish you'd come here to ask me something else. Anything else. Honestly, I... I missed you guys, it was... Oh, and table's set for six, but i am sorry about y/n
Steve : look tony I'm happy for you, I really am. But this is a second chance, to get everyone back, to get y/n back home to save wanda and bucky and everyone else
Tony: I got my second chance right here, Cap. I can't roll the dice again. If you don't talk shop, you can stay for lunch. im sorry about y/n i really am
[We see Cap, Nat and Scott walking back to their car outside Tony's house.]
Nat: He's scared steve, i will help you get y/n back home
Steve: He's not wrong, but thank you nat. it means a lot
Scott: Yeah, but I mean, what are we gonna do? We need him. What, are we gonna stop?
Steve: No, I wanna do it right. We're gonna need a really big brain.
Scott: (Incredulous, pointing to Tony's house) Bigger than his?
[Cut to a cafe somewhere, we see Bruce Banner, but not the same one that we remember. He looks more... Professor Smart Hulk.]
Bruce: Come on, I feel like I'm the only one eating. [Pushing a plate forward] Try some of that. Have some eggs.
Scott: I'm so confused.
Bruce: [seriously] These are confusing times.
Scott: Right. No, no, that's not what I meant.
Bruce: [dropping the act] No, I get it. I'm kidding! I know. It's crazy. I'm wearing shirts now.
Scott: Yeah! Wh...How? Why?
Bruce: Five years ago, we got our asses beaten. Except it was worse for me. Because I lost twice. First, Hulk lost, then Banner lost. Then, we all lost.
Nat: No one blamed you, Bruce.
Bruce: I did. For years, I've been treating the Hulk like he's some kind of disease, something to get rid of. But then I started looking at him as the cure. Eighteen months in a gamma lab. I put the brains and the brawn together. And now look at me. Best of both worlds...
steve: bruce please we need help, we need everyone to return home, especially wanda and bucky. for y/n's sake, shes been missing for 5 years, the only two people who know how to calm her except me and nat are gone. wanda would especially know to get y/n to return home, help us please, if not for me then for y/n
Bruce: ok i will try and help, i know y/n means a lot to you steve, i will be at the compound soon
Nat: thank you Bruce
The scene cuts to Tony Stark in the kitchen washing dishes after dinner. As he finishes the last of them, stumbles upon a photo of both Stark and his daughter when she was younger, even though tony and y/n never got along, he still wants to give his birth daughter her happy ending. Tony finally wants his daughter to be happy. later that night Tony goes into his workshop and starts talking to his computer, generating a holographic model of something he's working on.
Tony: Look at a mod inspiration, let me see what check out. So, recommend one last sim before we pack it in for the night. This time, in the shape of a mobius strip, inverted, please F.R.I.D.A.Y
F.R.I.D.A.Y: even though you programmed me to only listen to y/n, i'll help you. Processing...
Tony: i know i did but this is to help y/n get her life back. please Give me that eigenvalue. That, particle factoring, and a spectral decomp. That will take a second.
F.R.I.D.A.Y: Just a moment.
Tony: And don't worry if it doesn't pan out. I'm just kinda -
F.R.I.D.A.Y: Model rendered.
In a complete shock of amazement, the render comes back as 99.987% successful. Tony falls back, bewildered by this discovery.
Tony: Shit!
MORGAN STARK: Shit.
Morgan, who has been hiding behind him all this time, giggles as she repeats the word Tony just uttered.
Tony: [Whispering] What are you doing up, little miss?
Morgan: Shit.
Tony: No, we don't say that. Only Mommy says that word. She coined it, it belongs to her.
Morgan: Why you up?
Tony: 'Cause I got some important shit going on here. [Morgan gives Tony a taste of the incredulous] What do you think? No, I got something on my mind. I got something on my mind.
Morgan: Was it Juice Pops?
Tony: Sure was. That's extortion. Great minds think alike. Juice Pops, exactly was on... [Looks back to the model, Then turns back] my mind.
[In Morgan's room]
Tony: You done? Yeah, now you are. [Tony wipes Morgan's lips and pushes her head onto her pillow] That face goes there.
Morgan: Tell me a story.
Tony: A story... Once upon a time, Maguna went to bed. The end.
Morgan: [Giggling] That's a horrible story.
Tony: Come on, that's your favorite story.
Morgan: dad, can i ask you something
Tony: ofc honey
Morgan: i know y/n is my older sister but why hasnt she been to visit ? and why did Captain America say that she was his ?
Tony: thats a lot of questions morgan
Morgan: please answer them dad
Tony: ok, you deserve the truth, y/n is now steve's daughter, he adopted her after i gave him permission as i was a horrible father to her, i was really bad to her, i regret everything i said to her. i just hope one day she can forgive me, i am trying to be a better father for you maguna
Morgan: you are a good father, dad. you cant change the past but you can always change the present
Tony: I love you tons. [Kisses Morgan on the forehead.]
Morgan: I love you 3000.
Tony: [Silently] Wow. [Turns off the lamp] 3000. That's crazy. [Closed the door] Go to bed. Or I'll sell all your toys. Night, night.
Cut to the living room where Pepper is reading a book sitting on the couch. Tony paces in front of the fireplace.
Tony: Not that it's a competition, but she loves me 3000. You were somewhere on the low 6 to 900 range. [Pepper scoffs]
Tony: [Absentmindedly] What are you reading?
Pepper: Oh, it's just a book on composting.
Tony: [Still absentmindedly] What's new with composting?
Pepper: Just -
Tony: I figured it out, by the way.
Pepper: You know, just so we're talking about the same thing -
Tony: Time travel.
Pepper: [Amazed] What? Wow... That's amazing, and... terrifying.
Tony: That's right.
Pepper: We got really lucky
Tony: Yeah, I know. you couldve got dusted away or morgan couldve have
Pepper:i know tony, but A lot of people didn't, including wanda. imagine how y/n is feeling without her
Tony: i know pep, but I can't help everybody.
Pepper: It sort a seems like you can.
Tony: Not if I stop. I can put a pin in it right now, and stop.
Pepper: Tony, trying to get you to stop has been one of the few failures of my life. [Tony smiles]
Tony: I sometimes feel I should put it in a locked box and drop it at the bottom of a lake... and then go to bed.
Pepper: But would you be able to rest?
Tony: no but, i would put a pin in it for you
Pepper: my opinion would be to help to bring back everyone, to help your first daughter for her happiness tony. just because you too dont really get along and shes no longer your daughter, you should at least try and help them to get them all back
Tony: ok, i will help them, but im coming back as soon as its done
Cut to a lab in the Avengers Compound, we see Bruce fiddling with buttons on a panel. Scott is in his Ant-Man costume in front of his van, with the back open to show the Quantum Tunnel. Nat and Steve are beside Bruce
Bruce: Okay, here we go. Time travel test number one. Scott, fire up the uhhh... the van thing.
[Scott opens the portal]
Steve: Breakers are set, emergency generators are on standby.
Bruce: Good. 'Cause if we blow the grid, I don't wanna lose Tiny here in the 1950's. [Scott, Nat and Cap give Bruce a panicked look]
Scott: Excuse me?
Nat: He's kidding. [In a hushed tone to Bruce] You can't say things like that!
Bruce: Just... It was a bad joke.
Nat: You were kidding, right?
Bruce: [Whispering to Nat] I have no idea. We're talking about time travel here. Either it's all a joke, or none of it is. [Loudly and gives Scott a thumbs up] We're good! Get your helmet on, Scott. I'm gonna send you back a week, let you walk around for an hour, then bring you back in 10 seconds. Makes sense?
Scott: Perfectly not confusing.
Steve: Good luck, Scott. You got this.
Scott: You're right. I do, Captain America.
[Bruce presses a button, and Scott disappears into the Quantum Tunnel.]
Bruce: On the count of three. 3... 2... 1!
Bruce presses a button, and someone in the Ant-Man suit comes back. A teenager in appears out of it.
TEEN SCOTT: Uh, guys? This...this doesn't feel right.
Steve: What is this?
Bruce: What's going on?
Nat: That...who is that?
He pushes another couple of buttons, trying to fix the problem.
Bruce: Hold on. [Panicking]
Nat: Is that Scott?
TEEN SCOTT: Yes, it's Scott!
Teen Scott gets sucked in back into the quantum tunnel, and it appears to be an old man in the Ant-Man suit.
OLD SCOTT: Ow! My back!
Steve: What is this?
Bruce: Can I get a little space here.
Steve: Yeah yeah. Can you bring him back?
Bruce: I'm working on it! [Tapping the side of the button pad, trying to pull back Scott]
After a moment, another person appears in front of them. This time, it's a baby in the Ant-Man suit.
Steve: It's a baby.
Bruce: It's Scott.
Steve: As a baby!
Bruce: He'll grow.
Steve: Bring Scott back!
Bruce: [motioning to Nat] When I say kill the power, kill the power.
Nat: Oh my god. [rapidly walk near to the generator]
Bruce : And... Kill it!
Nat pulls down a lever, and everything shuts down. Scott, the normal Scott, gets spewed back out again.
Scott: somebody peed my pants
Nat: Oh thank god.
Scott: But I don't know if it was "baby" me or "old" me...Or just "me" me.
Bruce: [holds up his his hands in a dramatic way] Time travel!
Steve says nothing. He simply shakes his head and walks away
Bruce: What? I..I see this as an absolute win!
at this time bruce and rocket went to see thor
SCREEN TITLE: TOKYO
[After seeing a Quinjet flown to the capital, the scene cuts to a nightclub in the city of Tokyo, as the entertainment still intact, loads of dead bodies of yakuza members are seen as a hooded figure throws a shuriken at another yakuza member firing at her. They are shouting something in Japanese, as two more men come out of nowhere and draw out their UZIs.]
THUG #1: あいつだ! アキヒコさんを！(Romanized: Aitsu da! Akihiko-san wo!) (Translated: It's her! He's after Akihiko!)
Both thugs fire their SMGs as both got slain by a shuriken. A yakuza member wielding a katana charges at him in the stairs, but is immediately overthrown and slain by the Ronin. Ronin then fights another sword-wielding thug, which is thrown outside the glass, killing him. The camera passes through two more buildings as the fighting ensues with different screams, shouts, more havoc inside, and gunfire. A man in a dark raincoat jumps through the glass window, with the Ronin doing the same, as both of them lands in a dark alleyway. The man in the raincoat turns to the Ronin, who just landed after him. It was Akihiko, the leader of a yakuza gang, whose head being hunted by the Ronin himself.
AKIHIKO: てめえ なぜこんなことをする? 俺たちてめえになにもしてねぇだろ！(English: Why are you doing this? We never did anything to you!)
RONIN: [As he draws out his katana and reversibly wields it.]地球の半分 サノスにやられた... お前はなぜ無事なの...(English: You survived... Half of the planet didn't. They got Thanos... you get me.)
Both sides engaged in combat as Ronin pierces his stomach, but doing only minor damage to him.
RONIN: [Also in Japanese] お前はもう十分殺しただろ(Romanized:Omae mo jūbun korshita daro) You're done hurting people.
AKIHIKO: [Japanese]俺らがだと? 気でも狂ったか! (Orera ga dato? Ki demo kurutta ka!) [he gestures to all the scattered bodies of his henchmen and chuckles] (English: WE hurt people? You're crazy!)
Akihiko charges, which Ronin immediately blocks. Both clang swords for two seconds, seeming that the yakuza leader has the upper hand, but Ronin punches him in the face, and sword-points him to his throat, in which Akihiko is temporarily petrified.
He lowers down his sword as if he is about to surrender, but charges again at Ronin. Both swords clashed as Ronin slices his stomach, losing stamina, but gaining more strength from his rage.
AKIHIKO: [in a Gatotsu-like sword stance] 死ね! (Romanized: Shine!) (English: DIE!)
They both draw their katanas and the sword-fight continues. Ronin is clearly a better fighter, but Akihiko is also quite experienced. They clang swords, and for a second, it looks like Akihiko has the upper hand swinging at Ronin's neck. Ronin, however, ducks and slides under the katana, and slices Akihiko in the stomach as he slides past. Akihiko, now fatally injured, drops his katana.
AKIHIKO: 待て! 助けてくれ! お前に何でもやる! 何が欲しい? (Romanized: Mate! Tasukete kure! Omae ni nan demo yaru! Nani ga hosī? (English: Wait! Help me! I'll give you anything! What do you want?)
RONIN: [Raising his katana, in English] What I want... You can't give me.
He thrusts the blade downwards into Akihiko's stomach. The body of the Japanese falls to the ground. Ronin grabs the sword, and wipes it on his gauntlet, ridding it of the blood of Akihiko. She notices someone behind her, and grabs her mask, and slides it off her head, revealing herself as y/n stark, who has gone on a rampage since the decimation. She turns around and looks at Nat, who is standing behind her, holding an umbrella, and in casual clothes.
Y/n: You shouldn't be here.
Nat: Neither should you.
Y/n: I've got a job to do.
Nat: Is that what you're calling this? Killing all these people isn't gonna bring wanda or bucky back.
[y/n starts to look emotional, on the verge of crying.]
Nat: We found something. A chance, maybe...
y/n: [Now openly crying] Don't...
Nat: Don't what?
y/n: ...don't give me hope.
Nat: I'm sorry I couldn't give it to you sooner, y/n
