Steve
We've been hunting Thanos for three weeks now — deep space scans and satellites, and we got nothing. Tony, you fought him...
S Stark
Who told you that? I didn't fight him. No, he wiped my face with a planet while the Bleecker Street Magician gave away the stone. That's what happened, there's no fight...
Steve
Okay, did he give you any clues, any coordinates, anything?
S Stark
I saw this coming a few years back, I had a Vision, but I didn't want to believe it. I thought I was dreaming.
Steve
Tony, I'm going to need you to focus...
S Stark
And I needed you, as in past tense. That trumps what you need. It's too late, buddy. Sorry. [standing up] You know what I need? [knocks his cereal bowl away in anger] I need a shave. And I believe I remember telling all of youse...
R Rhodes
Tony, Tony, Tony...
S Stark
...alive and otherwise, that what we needed was a suit of armor around the world! Remember that? Whether it impacted our precious freedoms or not, that's what we needed!
Steve
Well, that didn't work out, did it?
S Stark
I said we'd lose. You said, "we'll do that together too." Guess what, Cap? We lost, and you weren't there. But that's what we do, right? Our best work after the fact? We're the Avengers, we're the Avengers? Not the Pre-vengers, right? Okay?
R Rhodes
You made your point. Just sit down.
S Stark
Nah, nah. Here’s my point.
R Rhodes
Tony, you’re sick! Sit down! Sit!
S Stark
[points to Carol Danvers]
She’s great, by the way! We need you—you're new blood! Bunch of tired old mules! I got NOTHING for you, Cap! I've got no coordinates, no clues, no strategies, no options... zero, zip, nada. No trust — liar. [Tony takes off his arc reactor and slaps it into Steve's hand] Here, take this. You find him, you put that on, you hide...
Steve
[Tony falls to the ground. Steve is by his side and everyone is starting to gather.]
Tony!
S Stark
I'm fine. I... [collapses]
R Rocket
[The team attacks Thanos at his home. As Steve and Natasha enter, Rocket turns the Infinity Gauntlet over to find the Infinity Stones missing]
Oh, no...
CA Captain America
[to Thanos]
Where are they?
CM Captain Marvel
[Tightens her vise grip on Thanos' throat]
Answer the question.
Thanos
The universe required correction. After that, the stones served no purpose beyond temptation.
B Bruce
You murdered TRILLIONS! [shoves Thanos to the ground]
Thanos
You should be grateful. [gets punched by Bruce]
BW Black Widow
Where are the stones?
Thanos
Gone. Reduced to atoms.
B Bruce
You used them two days ago!
Thanos
I used the stones to destroy the stones. It nearly killed me, but the work is done. It always will be. I am... inevitable.
WM War Machine
We have to tear this place apart. He has to be lying!
Nebula
My father is many things. A liar is not one of them.
Thanos
Ahhh. Thank you, daughter. Perhaps I treated you too harshly– [Gets decapitated by Thor]
R Rocket
What? What did you do?
Thor
I went for the head.
Banner
[Inside the Avengers Compound, the heroes are conducting a time travel experiment]
Okay, here we go. Time travel test number one. Scott, fire up the uhhhh…the van thing. [Scott opens the portal]
Steve
Breakers are set, emergency generators are on standby.
Banner
Good. 'Cause if we blow the grid, I don't wanna lose tiny here in the 1950's.
Scott
Excuse me?
N Natasha
He's kidding. You can't say things like that.
Banner
It was a bad joke.
N Natasha
You were kidding, right?
Banner
[whispering to Romanoff]
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!
Banner
On the count of 3. 3…2…1!
Young Scott
[Bruce presses a button, and Scott disappears into the Quantum Tunnel. In 5 seconds, Bruce presses a button, and someone in the Ant-Man suit comes back. A teenager appears out of it]
Uh, guys? T-This doesn't feel right.
Steve
What is this?
Banner
What's going on?
Banner
[Banner pushes another couple of buttons, trying to fix the problem]
Hold on.
Young Scott
[irritated]
Yes, it's Scott!
Elderly Scott
[Scott gets sucked in back into the quantum tunnel, and it appears to be an old man in the Ant-Man suit]
OWW! My back…!
Steve
What is this?
Banner
Can I get a little space here.
Steve
Yeah, yeah. Can you bring him back?
Banner
I'm working on it! [taps the side of the button pad, trying to pull back Scott]
Steve
[After a moment, another person appears in front of them. This time, it's a baby in the Ant-Man suit]
It's a baby.
Banner
It's Scott!
Banner
He'll grow!
R Rogers
[exasperated]
Bring Scott back!
Banner
When I say kill the power, kill the power.
N Natasha
[annoyed, she goes to kill the power]
Oh, my God.
Banner
[configuring the time machine]
And…kill it!
Scott
[Natasha kills the power as Banner sends baby Scott back into the Quantum Realm and retrieves Scott's present self, who is shaken from the Avengers' experiment]
Somebody peed my pants…
R Romanoff
Oh, thank God.
Scott
But I don't know if it was baby-me or old-me. Or…just me-me.
Banner
Time travel! [Steve just shakes his head and walks away] What? I see this as an absolute win.
Steve
Okay, so the "how" works. Now we gotta figure out the "when" and the "where." Almost all of us has had an encounter with at least one of the six Infinity Stones.
S Stark
Well, I'd substitute the word "encounter" for "damn well near been killed by" one of the six Infinity Stones.
Scott
I haven't, I don't even know what the hell you're all talking about.
Banner
Regardless, we only have enough Pym Particles for one round trip each, and these Stones have been in a lot of different places throughout history.
S Stark
Our history. So, not a lot of convenient spots to just drop in.
C Clint
Which means we have to pick our targets.
Steve
Let's start with the Aether. Thor, what do you know?
N Natasha
[Thor is sitting on a chair with his sunglasses on]
Is he asleep?
R Rhodey
No. I'm pretty sure he's dead.
Thor
[wakes up]
Where to start? Umm…the Aether, first, is not a stone, someone called it a stone before. It's more of a…an angry sludge thing, so…someone's gonna need to amend that. Here's an interesting story though, many years ago…my grandfather had to hide the stones from the Dark Elves, wooooh, scary beings. So Jane… [an image of Jane Foster pops up on the screen] Oh, there she is. That's Jane. She's– an old flame of mine. She– she stuck her hand inside a rock this one time– and then the Aether stuck itself inside her. And she became very, very sick. So I had to take her to Asgard, which is where I'm from. And we had to try and fix her. We were dating at the time, you see. I got to introduce her to my mother…who's dead… [seeming on the verge of tears] …and, oh, you know, Jane and I aren't even dating anymore, these things happen though you know, nothing last forever… [Tony starts to push Thor back to his chair] I'm not done yet, the only thing permanent in life is impermanence.
S Stark
Awesome. Eggs? Breakfast?
Thor
No. I'd like a Bloody Mary.
R Rocket
Quill said he stole the Power Stone from Morag.
Scott
Is that a person?
R Rocket
Morag's a planet, Quill was a person.
Scott
A planet? Like in outer space?
R Rocket
[Mockingly]
Oh, look: it's like a little puppy, all happy and everything. [starts petting Scott] Do you want to go to space? You want to go to space, puppy? I'll take you to space!
Nebula
Thanos found the Soul Stone on Vormir.
N Natasha
[in a business-like tone]
What is Vormir?
Nebula
A dominion of death, at the very center of Celestial existence. It's where... Thanos murdered my sister.
Scott
Not it.
N Natasha
[lying on a paper-filled table]
That Time Stone guy…
Banner
[lying down on the floor]
Doctor Strange.
N Natasha
Yeah, what kind of doctor was he?
S Stark
Neuro stuff meets rabbit from a hat. Nice place in the Village, though.
Banner
Yeah. Sullivan Street. [Corrects himself] Hmm– Bleecker.
N Natasha
Wait, he lived in New York?
S Stark
[Sarcastically]
No, he lived in Toronto.
N Natasha
Guys, if you pick the right year, there are three Stones in New York.
Banner
[Sits up in surprise]
Shut the front door!
IM Iron Man
[After the Snap is undone, Iron Man, Captain America, and Thor approach Thanos from 2014 after his attack on the New Avengers Facility, who is fully aware of his plan's success and his fate and the Avengers' attempts to undo his plan, and has arrived at Earth]
What's he been doing?
Thor
Absolutely nothing.
CA Captain America
Where are the stones?
IM Iron Man
Somewhere under all this. All I know is he doesn't have them.
CA Captain America
So we keep it that way.
Thor
You know it's a trap, right?
IM Iron Man
Yeah. And I don't much care.
Thor
Good. Just as long as we are all in agreement... [Summons Mjølnir and Stormbreaker] Let's kill him properly this time.
Thanos
[The three walk over to confront Thanos face-to-face]
You could not live with your own failure. Where did that bring you? Back to me. I thought by eliminating half of life, the other half would thrive. But you've shown me that's impossible. And as long as there are those that remember what was, there will always be those that are unable to accept what can be. They will resist.
IM Iron Man
Yep, we're all kinds of stubborn.
Thanos
I'm thankful. Because now, I know what I must do. I will shred this universe down to its last atom - and then, with the stones you've collected for me, create a new one. Teeming with life, that knows not what it has lost, but only what it has been given. [Thor starts up Stormbreaker and Mjolnir] A grateful universe.
CA Captain America
Born out of blood.
Thanos
They'll never know it. Because you won't be alive to tell them. [The three fight Thanos]
DS Doctor Strange
[Doctor Strange has magically transported all the previously disintegrated Avengers and their allies, hundreds in all, to the battlefield to face Thanos' hordes]
Is that everyone?
W Wong
What, you wanted more?
CA Captain America
[Giant-Man emerges with Professor Hulk, War Machine, and Rocket. The Avengers, Guardians of the Galaxy, Wakandans, Asgardians, Masters of the Mystic Arts, and Ravagers take up battle positions]
Avengers... [he summons Mjolnir] ...assemble.
SW Sam Wilson
[Last lines: Steve fails to come back immediately after returning Mjolnir and the Infinity Stones in their original places in time. In 2023, Bucky Barnes and Sam Wilson see an elderly Steve sitting on the bench near them.]
Cap?
Steve
Hi, Sam.
S Sam
So did something go wrong, or did something go right?
Steve
Well, after I put the stones back, I thought, maybe I'll try some of that life Tony was telling me to get.
S Sam
How did that work out for you?
Steve
It was beautiful.
S Sam
I'm happy for you. Truly.
Steve
Thank you.
S Sam
Only thing bumming me out is the fact I have to live in a world without Captain America.
Steve
Oh. That reminds me… [Brings out his shield.] Try it on. [Sam look over to Bucky, who nods, and Sam holds Steve's shield.] How does it feel?
S Sam
Like it's someone else's.
Steve
It isn't.
S Sam
Thank you. I'll do my best.
Steve
That's why it's yours. [Shakes Sam's hand]
S Sam
[Seeing elderly Steve's wedding ring]
You wanna tell me about her?
Steve
No. No, I don't think I will.
[In 1948, Steve has time traveled back to be with Peggy Carter. They are dancing to "It's Been a Long, Long Time", and end with a kiss.]
