5 YEARS LATER

At the Avengers compound, Natasha is making herself a peanut butter sandwich as she is surrounded by holograms of the others.

"Yeah, we boarded the highly-suspected warship Danvers pinged." Rocket says.

"It was an infested garbage scow." Nebula says.

"And now we smell like garbage." Rocket complains.

"Well, you were closer." Carol replies.

"Okoye, did you get a ping on the tremors?" Natsha asked her from Wakanda.

"'T'was a mild subduction under the African plate." She answers.

"So, how do we handle it?" Natasha asked.

"Nat. It's a earthquake in the ocean. We handle it by not handling it." Okoye answers.

"Carol, are we seeing you here again next month?" Natasha asked her.

"It's not likely." She answers.

"What? You gonna go get another haircut?" Rocket asked.

"Listen, furball, what's happening on earth is happening on thousands of other worlds. So you won't be seeing me for a while." Carol says back.

"Okay, good point." Rocket mumbled.

"Okay, well, this channel is always open if you need anything." Natasha says and they all leave except Rhodes. "Where are you?" She asked him.

"Mexico." Rhodey answers. "They found a lead to a warehouse and when they got there...it was like a massacre. Definitely cortel guys"

"It was probably a rival gang." She says.

"Except, it's not. It's definitely Barton." Rhodes breaks to her. "I gotta tell you, A part of me doesn't even wanna find him." He states sympathetically. "I'm heading back tomorrow. See you then." He says as he shuts off the hologram.

Natasha sits back down and looks over to a photo of her and Peter that was taken years ago on her desk and starts crying at the memory of her dead nephew.

"You know, I'd offer to take you someplace just to get you out of here, but I have a feeling I should come back on a better day." Steve says and Natasha looks up and sees him.

"Come to do your laundry?" She asked him.

"Came to see a friend." He says.

"Well, your friend is doing fine as you can see." She informs him while wiping the tears.

"You know, I saw a pod of whales when I was coming over the bridge."

"In the Hudson?" She asked.

"There's fewer ships polluting the waters." He explained.

"Okay, if you're about to tell me that there's a bright side to everything that's happened, you're about to be hit in the head with a peanut butter sandwich." She warns him.

"Sorry. I was just with my group, telling them that it's time to move on. Some of them do, but not us." Steve says as he sits down across from her.

"If I move on, who does any of this?" Natasha asked him.

"Maybe it doesn't have to be done." He answered.

"I used to have nothing, and then I got this. This job. This family. And I was better because of it. And even though they're gone...I'm still trying to be better." She explains to him. She was nothing but an assasian, then she was an agent of S.H.I.E.L.D., then she became an aunt and mentor to a child she easily loved.

"I think we both need to get a life." Steve tells her.

"You first." She replies when a alert appears in her face. She flips it on and the camera outside activates.

"Oh, hi is anyone home?!" They look and see Scott. "This is Scott Lang! We met a few years ago st the airport in Germany! I got really big!" He says.

"Is this an old message?" Steve asked in shock.

"Ant Man? I know you know that!" Scott says.

"It's the front door." Natasha answers.

"Yeah, that's me, can you buzz me in?" Scott asked.

Later, he's inside pacing and mumbling.

"Scott." Steve says and it snaps Scott out. "You okay?" He asked him.

"Look, have either of you guys ever studied quantum physics?" Scott asked.

"Only to start up a conversation." Natasha jokes, knowing Peter tried to explain it to her years ago.

"Okay, five years ago, before...Thanos, I was in a place called the quantum realm. It's like a microscopic universe." Scott says explaining the quantum realm. "To get there, you have to be incredibly small. Hope my...She was supposed to pull me out, but then Thanos happened." Scott explains.

"So that's where you've been for the past 5 years?" Natasha asked.

"No, you see, for me it was 5 hours." He tells her and they're confused. "In the quantum realm, time and space don't work the same. Everything is unpredictable. Is that anyone's sandwich?" He asked seeing Natasha's sandwich and walks over and takes a bite out of it.

"Scott. What are you talking about?" Steve asked, not understanding what he's talking about.

"Look, I can't stop thinking about it, what if...we could harness the quantum realm energy, used it to go back to a place, like...before Thanos." Scott tries explaining.

"Are you talking about a time machine?" Steve asked.

"No, that's ridiculous. It's more like a...okay, yeah, a time machine. I know, it's crazy." Scott says.

"Scott, I get emails from a talking raccoon. Nothing's crazy to me." Natasha states.

"So, who can we talk to about this?" Scott asked.

-

"Are these our gojis?" Tony stood in the kitchen with Pepper, helping her prepare lunch. He could see Gerald, his rather spritely alpaca, out the window, chopping on the grass. Ernő kept circling the kitchen, meowing as he went, obviously ready for his lunch too.

"They are not." Pepper informed him as he examined the ones in the bowl he was holding.

He raised his eyebrow, "What's wrong with ours?"

Pepper stopped cutting the vegetables, to glare at him, "Your alpaca ate them all."

Tony clicked his tongue, "Aww."

"All of them."

He moved around and stopped by her other side, "What a glowing endorsement." He sang as he placed the bowl down beside her, "First of all, Gerald is ouralpaca."

Pepper snorted and shook her head, "He's not my alpaca if he's eating my gojis."

"Okay..." Tony took a handful of gojis and hovered them over the salad bowl, he actually had no idea what he was doing. He could cook, yes, but he didn't understand anything that Pepper made, "They're going to be nice in the salad, right?"

"No, no." Pepper snapped, holding her hand out to stop him, "Don't, don't, don't." Tony stopped in his tracks, and retracted his hand, "Can you put it down?" She asked, "Get out of my kitchen."

"So, we're good here, right?"

"Yeah, we're great." Pepper said, somewhat sarcastically, as Tony looped his jumper over his arms, "Tell Madam Secretary that lunch is in five."

Tony clicked the door open, "I will collect our alpha female posthaste." He informed her, before stepping out, he stopped a few meters away from Gerald and whistled to gain his attention, "Hey you, yes you, look at me when I'm speaking to you. Stay away from mom's gojis or I'll give you to the local petting zoo, okay?"

Gerald was unphased and went back to grazing the grass. "Oh, forget it." Tony rolled his eyes and turned back around, skipping down the stairs toward Morgan's tent, where she spent most of her time.

Tony clapped his hands together as he closed the distance between him and the tent, "Chow time!" He announced as he grabbed one of her many plush toys of the ground, he sat down on a small wooden chair, "Morgoona?" He called, "Morgan H. Stark." He proclaimed, "Want some lunch?"

The tent flaps moved, and Morgan came out, with her hand raised, showing off her toy Iron Man repulsor. "Define lunch or be disintegrated." Alarmingly, she was wearing the mask that went with Pepper's Rescue Armor, and it was somehow turned on.

"Okay," Tony said, with his hand held up in surrender. The mask was too big for Morgan's head, and she was having to hold onto it, "You should not be wearing that, okay?"

He moved forward, placing his hands on her shoulders, "That is part of a special anniversary gift, I'd made it for Mom." He leaned closer, pressing a kiss on the side of the mask, he moved back and slowly pulled the helmet off her head, revealing her messy wind-swept hair underneath, he was surprised she'd managed to see through it, "There you go." He muttered as he brushed her hair out of her eyes, "You thinking about lunch? I can give you a handful of crickets on a bed of lettuce."

"No," Morgan said, trying to react stern to his humour but he could see her fighting the urge to giggle.

"That's what you want." Tony teased, he reached down picking up the Rescue helmet, "How did you find this?"

"Garage." Morgan answered nonchalantly as she twirled her hair around her hands.

"Really?" Tony narrowed his eyes, "Were you looking for it?"

"No." She said defensively, "I found it though."

"You like going to the garage, huh?" Tony asked as he scooped her up, "So does daddy." He started to walk up the garden, "It's fine, actually." He told her looking down at the mask in his hand, "Your Mom never wears anything I buy her."

Tony then looks and sees a car approaching and the others exit. The fact that Scott Lang was behind Natasha, was an immediate red alarm too, considering up until right now, Tony thought he was dead.

Later, they're all talking and explaining the plan.

"Now, we know what it sounds like." Scott says after explaining everything.

"Tony, after everything you've seen and done, is this possible?" Steve asked.

"Quantum fluctuation messes with the Planck scale, which will trigger the Deutsch Proportion. Can we agree on that?" Tony says as he hands them some drinks. "In English, it means you're not coming home."

"I did." Scott says.

"No. You accidentally survived. That's different. It's a billion to 1 shot." Tony replies to that. " And now you wanna pull a...what did you call it?"

"A...Time heist." Scott says.

"Why didn't we think of this before? Oh, because it's laughable." Tony states.

"The stones are in the past. If we can go back in time, we can get them back here." Steve defends the plan.

"Snap our own fingers, and bring everyone home." Natasha finishes, willing to give her life if it means she gets to bring Peter back.

"Or mess with everything up even worse." Tony interjected.

"I don't believe we would." Steve says.

"Gotta say. I sometimes miss tat giddy optimism." Tony informs him. "I don't do something if there's no hope of it working or if I can't find a safe way to execute said time heist." He explains. "And I'd think the most likely outcome will be all of us pushing up daisies."

"Not if we follow the rules of time travel." Scott tries explaining. "Okay? That means no talking to our past selves, no betting on sporting events." Scott explains.

"I'm gonna stop you there. You're betting our lives, our universe...based off of Back to the Future?" Tony asked, not liking this.

"No." Scott says.

"Good. Because you had me worried. 'Cause that'd be bullshit." Tony says. "That's not how quantum physics works."

"Tony. We have to make a stand." Natasha says.

"We tried to stand, remember? And look where it got us." Tony replies.

"Look. I know you've got a lot on the line. You have a wife, a daughter. But I lost someone important to me. A lotta people did." Scott says trying to convince him. "And now, we have a chance to bring them back, everyone back. And you're telling me that you won't even..." Scott starts and Tony cuts him off before he finished.

"That's right, Scott, I won't." Tony says when the door opens and Morgan comes over to him.

"Mommy told me to come save you." She says as he picks her up.

"Yep, I'm saved." Tony says as he stands up. "I wish you were coming here to ask me something else. Anything else."

"Tony, I'm happy for you, but this is a second chance here." Steve says trying to convince one more time.

"This is my second chance right here." Tony says. "If you wanna stay, we can have the table set for you guys, if not, you know your way back." He goes inside with Morgan.

"He's scared." Natasha says as they head back.

"Well, he's not wrong." Steve says.

"Yeah, But I mean what are we gonna do? We need him. We gonna stop?" Scott asks them.

"No, I wanna do it right. We're gonna need a really big brain." Steve tells him.

"Bigger than his?" Scott questioned.
