[We cut to a montage showing reunions and celebrations. At Clint Barton's farm, he joyfully reunites with his family. At Peter Parker's school, Peter and Ned meet in the hallways. They share a handshake before giving each other a heartfelt hug. In San Francisco, Scott Lang watches fireworks with Cassie Lang and Hope Van Dyne. In Wakanda, T'Cahlla, Shuri, and Ramonda oversee the celebrations from their balcony. We then see Sonic and Tails repairing their house with the help of Knuckles, Amy and Sally, but unknown to them, Shadow is Staring at them in the shadows with a smile on his face. We then see Bruce Wayne return home to his family, he lifts Damien onto his shoulders and kisses Talia. Over all this, we hear Tony's voice narrating.]

TONY STARK (voiceover): Everybody wants a happy ending, right? But it doesn't always roll that way. Maybe this time. I'm hoping if you play this back, it's in celebration. I hope families are reunited, I hope we get it back, and something like a normal version of the planet has been restored. If there ever was such a thing. God, what a world. Universe, no, Multiverse, now. If you told me ten years ago that we weren't alone, let alone, you know, to this extent, I mean, I wouldn't have been surprised. But come on, you know? The epic forces of darkness and light that have come into play. And, for better or worse, that's the reality Morgan's gonna have to find a way to grow up in.

[Cut to the Stark household. Pepper, Morgan, Happy Hogan, and Rhodey all watch Tony's holographic message being projected from his Iron Man helmet. Tony is sitting down recording the message.]

TONY STARK (hologram): So I thought I'd probably better record a little greeting... In the case of an untimely death on my part. I mean, not that, death at any time isn't untimely. This time travel thing that we're gonna try and pull off tomorrow, it's– it's got me scratching my head about the survivability of it all. That's the thing. Then again, that's the hero gig. Part of the journey is the end. [Tony suddenly gets up walking towards his camera] What am I even trippin' for? Everything's gonna work out exactly the way it's supposed to. [He leans down and smiles. He is looking straight at Morgan] I love you 3,000.

[The message ends and the hologram cuts out.]

[Cut to outside the cottage. Pepper carries a wreath out of the house to an audience waiting outside for the intimate funeral. She lays the wreath on the lake. On top of the wreath is Tony's first arc reactor which Pepper had framed with the words "Proof That Tony Stark Has a Heart" back in 2008. The camera slowly pans to see Pepper, Morgan, Happy Hogan, & Rhodey, all being joined by Steve Rogers, Peter Parker, May Parker, Thor, Bruce Banner, Doctor Strange, Wong, Scott Lang, Hope Van Dyne, Janet Van Dyne, Hank Pym, Peter Quill, Nebula, Rocket, Teenage Groot, Drax, Mantis, T'Challa, Okoye, Shuri, Clint Barton & his family, Wanda Maximoff, Bucky Barnes, Sam Wilson, Harley Keener, Sonic, Sally, Knuckles, Amy, Tails, Shadow, Bruce Wayne and his family, Clark Kent and Lois Lane, Diana Prince, Hal Jordan, Barry Allen, Secretary Ross, Maria Hill, Carol Danvers, and Nick Fury, silently watching the wreath float away.]

[Cut to Clint and Wanda, standing by the riverside shortly afterwards.]

CLINT: You know, I wish there was a way– that I could let her know. That we won. [Looks over to Wanda.] We did it.

WANDA MAXIMOFF: She knows– They both do.

[Clint gives her a side hug and Wanda reciprocates.]

[scene cuts to Happy and Morgan.]

HAPPY: How you doing, Squirt?

MORGAN STARK: Good.

HAPPY: You good? Okay. You hungry?

MORGAN STARK: Mm. Hm.

HAPPY: What do you want?

MORGAN STARK: Cheeseburgers.

HAPPY: You know your dad liked cheeseburgers? I'm gonna get you all the cheeseburgers you want.

MORGAN STARK: Okay.

[Following the funeral for Tony, we cut to Thor and Valkyrie in New Asgard.]

VALKYRIE: So, when can we expect you back?

THOR: Um– about that–

VALKYRIE: Thor. Your people need a king.

THOR: No, they already have one.

VALKYRIE: That's funny. You're being serious?

[Thor nods his head]

THOR: It's time for me to be who I am rather than who I'm supposed to be. But you, you're a leader. That's who you are.

VALKYRIE: You know I'd make a lot of changes around here.

THOR: I'm counting on it. Your Majesty.

[Thor offers Valkyrie a farewell handshake]

VALKYRIE: What will you do?

THOR: I'm not sure. For the first time in a thousand years, I– I have no path. I do have a ride, though.

[Camera pans to the Benatar parked on the cliff]

ROCKET: Move it or lose it, hairbag.

[scene cuts to Quill searching for Gamora on the screen as Thor walks in he closes it]

THOR: Well, here we are. Tree! Good to see you. Well– [Thor removes his shades and taps Quill on the shoulder] The Asgardians of the Galaxy, back together again. Where to first? [Thor touches the screens map to pick their destination]

QUILL: Hey, just so you know, this is my ship still. I'm in charge.

THOR: I know. I know. Of course, you are. Of course.

QUILL: See, you say of course, but then you touch the map. It makes you think that maybe you didn't realize I was in charge.

THOR: Quail– you– that– that's your own–

QUILL: Quail?

THOR: –insecurities in there. Okay? I'm merely trying to be of service and assisting.

QUILL: It's Quill.

THOR: That's what I said.

DRAX: You should fight one another for the honor of leadership.

NEBULA: Sounds fair.

[Quill looks around]

QUILL: It's not necessary.

THOR: It's not.

QUILL: Okay?

ROCKET: I got some blasters, unless you guys wanna use knives.

MANTIS: [enthusiastically] Oooh, yes. Please, use knives.

DRAX: Yeah, knives.

GROOT: I am Groot.

[Both Thor and Quill laugh but Quill tries to laugh harder]

QUILL: Not necessary...

THOR: There shall be no knifing one another. Everybody knows who's in charge.

QUILL: [glances at Thor] Me, right?

THOR: Yes, you. Of course. Of course. Of course.

[Scene cuts to Bruce, Steve, Sam and Bucky at the funeral]

BRUCE BANNER: Now, remember– You have to return the stones to the exact moment you got them. Or you're gonna open up a bunch of nasty alternative realities.

STEVE ROGERS: Don't worry, Bruce. Clip all the branches.

BRUCE BANNER: You know, I tried. When I had the gauntlet, the stones, I really tried to bring her back. [Looks at Steve] I miss her, man.

STEVE ROGERS: Me, too.

SAM WILSON: You know, if you want, I can come with you.

STEVE ROGERS: You're a good man, Sam. This one's on me, though.

[Steve goes over to Bucky]

STEVE ROGERS: Don't do anything stupid 'till I get back.

BUCKY BARNES: How can I? You're taking all the stupid with you.

[They both hug each other]

BUCKY BARNES: Gonna miss you, Buddy.

STEVE ROGERS: It's gonna be okay, Buck.

[Steve goes over to the Quantum portal and dons the Quantum suit]

SAM WILSON: How long is this gonna take?

BRUCE BANNER: For him? As long as he needs. For us? Five seconds.

[Steve picks up Mjolnir (2013)]

BRUCE BANNER: Ready, Cap? Alright. We'll meet you back here, okay?

STEVE ROGERS: You bet.

BRUCE BANNER: Going quantum. Three, two, one–

[Steve disappears into the Quantum portal]

BRUCE BANNER: And returning in, five, four, three, two, one–

[Steve doesn't appear on the pad. Bruce looks around the equipment]

SAM WILSON: Where is he?

BRUCE BANNER: I don't know. He blew right by his time stamp. He should be here.

[Bucky turns around from the pad]

SAM WILSON: Well, get him back.

BRUCE BANNER: I'm trying.

SAM WILSON: Get him the hell back!

BRUCE BANNER: Hey, I said, I'm trying!

BUCKY BARNES: Sam...

[Sam walks toward Bucky. Sam, Bucky, and Bruce see old looking Steve sitting on a log. Sam and Bucky go near him.]

BUCKY BARNES: Go ahead.

[Bucky has a smile forming and looks over to Sam. He walks towards the old man and instantly recognizes the now-elderly Steve Rogers]

SAM WILSON: Cap?

(OLD) STEVE ROGERS: Hi, Sam.

[Old Steve looks over to Sam]

SAM WILSON: So did something go wrong, or did something go right?

(OLD) STEVE ROGERS: Well, after I put the stones back, I thought, maybe I'll try some of that life Tony was telling me to get.

SAM WILSON: How'd that work out for you?

(OLD) STEVE ROGERS: It was beautiful.

SAM WILSON: I'm happy for you. Truly.

(OLD) STEVE ROGERS: Thank you.

SAM WILSON: Only thing bumming me out is the fact I have to live in a world without Captain America.

(OLD) STEVE ROGERS: Oh, That reminds me. [brings out his shield.] Try it on.

[Sam looks over to Bucky, who nods, and Sam holds Steve's shield.]

(OLD) STEVE ROGERS: How does it feel?

SAM WILSON: Like it's someone else's.

(OLD) STEVE ROGERS: It isn't.

[Sam tries to hold back tears]

SAM WILSON: Thank you. I'll do my best.

(OLD) STEVE ROGERS: That's why it's yours. [shakes Sam's hand]

SAM WILSON: [seeing elderly Steve's wedding ring] You wanna tell me about her?

(OLD) STEVE ROGERS: [smiling] No. No, I don't think I will.

[In the final scenes, Steve has time traveled back to the 1940s to be with Peggy Carter. They are seen dancing to "It's Been a Long, Long Time" in their home, and they end with a kiss.]
