Grace never actually goes to sleep, time getting away from her, and because of this she hears Tony moving around in the morning, up before anyone else. Curiously, she stops painting — the painting being not quite finished yet — and walks out into the hall, then downstairs.

Tony is fully dressed, drinking coffee rather quickly. His eyes widen when he sees her. "Grace? Why are you up?"

She shrugs. "I never went to bed."

He's really shocked then, and incredulous. "Grace Maria Stark, are you kidding me-?"

She waves him off. "Oh, you used to do it all the time."

"That doesn't mean that-"

"You never answered my question," she interrupts. "Why are you up?" She gestures to his outfit, which is clearly not meant for just hanging out at home. "Where are you going?"

He looks at her for a moment, then sighs deeply, looking down at the counter. "I figured it out," he says.

Confused, she asks, "Figured... what out?"

He looks up at her, eyes heavy. "Time travel."

She gasps. "Oh-"

"And I'm going to the compound now," he continues. "To tell them. Help them. Even though this is insane." He runs a hand through his hair. "But if I can do something about it, and I don't, then... it's my fault, right?"

Grace's hope returns, amidst her shock, and she's practically shaking with urgency and excitement. "I... Just- Just give me five minutes and I'll be ready to go." She turns to run back upstairs, but Tony stops her.

"Wait, wait, wait, go where?" he asks.

"With you," she says, as if it were obvious.

He sighs, knowing this was going to happen. "Grace-"

"Come on, Dad," she insists. He opens his mouth to argue, but she states her case before he can. "I want to be a part of this. I want to help you. Please, Dad. I can help, and you know it."

He thinks for a moment, and he knows, in any case, she deserves to at least be there. This is mostly for her, really. She's the reason he even looked into this at all. He sighs. "Your mom is probably gonna kill me, but fine. Five minutes. Come on."

She grins and runs back upstairs, pulling random clothes out of her closet, not caring if they match, brushing her teeth probably less thoroughly than recommended, and grabbing her hair brush to take with her in the car, along with her phone, which she has enough presence of mind to remember. Just before she leaves the room, though, a glint against her cork board catches her eye.

The necklace Peter gave her.

She takes a few more seconds to grab it, somehow putting it on as she leaves the room. She's still back downstairs in four and a half minutes.

"Let's go."

~~~~

Excited and hopeful, Grace's heart jumps when she sees the first glimpse of the compound, and she doesn't even care that all she had for breakfast was a granola bar that Tony grabbed for her on their way out. Seeing the compound doesn't hurt as much as it usually does (which, now, admittedly, is only a little) due to the circumstances.

She might actually get Peter back. The memories here wouldn't be bittersweet to think about. And they would be able to make new ones. Better ones. She almost thinks she's dreaming.

As they get closer, she sees that Steve is standing outside, dejected, even as he looks at the fast-moving car (reminding her of the drive to the airport before Afghanistan, a drive Grace will never forget) curiously.

Tony stops the car abruptly, but overshoots Steve due to the speed, and so has to back up in order to be directly in front of him. Grace laughs before Tony rolls the window down, looking at Steve.

Grace leans towards the window and smiles. "Hey, Steve."

"Why the long face?" Tony asks, before Steve can respond. "Let me guess, he turned into a baby?" He being Scott, the one who had the crazy idea in the first place.

Steve nods with a small sigh. "Among other things, yeah. What are you doing here?"

Tony, getting out of the car, doesn't answer his question. "It's the EPR Paradox. Instead of pushing Lang through time, you might've wound up pushing time through Lang. It's tricky — dangerous. Somebody should've cautioned you against it."

"You did," Steve admits, and Grace watches the conversation, leaning against the car on the passenger side.

"Oh, did I?" Tony replies, causing Grace to snort lightly. "Well, thank goodness I'm here. Regardless, I fixed it." He holds up his hand, where he's wearing a device he created before leaving the house. It looks a bit rudimentary, but it'll get the job done. "A fully functioning Time-Space GPS." Steve smiles, and Tony drops his hand. "I just want peace-" he holds up a peace sign as he says it "- and it turns out, resentment is corrosive, and I hate it."

"Me too," Steve replies.

Tony sighs. "We got a shot at getting these stones, but I gotta tell you my priorities. Bring back what we lost? I hope, yes. Keep what I found? I have to, at all costs. And-" he steps towards Steve "-maybe not die trying would be nice."

Steve holds out his hand, and Tony shakes it. "Sounds like a deal." He then looks at Grace, curious again. "You here to help?"

Her smile widens, and she walks around the car to stand next to them both. "You bet."

"She rushed out of the house this morning, which is why she's dressed like that," Tony adds, referring to Grace's unfortunate ensemble of neon orange leggings and a bright red t-shirt with an Iron Man helmet on it.

Grace looks down at herself. "Yeah, I didn't even know I had this shirt, if I'm being honest."

Tony looks at it for a moment, then declares, "I think it's Pepper's."

Grace nods. "That explains it."

"Anyway, I'm sure Nat has some suitable pants you can wear because whoever bought you those needs to be banned from buying you clothes for the rest of their life," Tony continues.

Grace laughs. "Pretty sure Harley sent me these as a joke for my birthday in, like, high school."

"Case in point."

Steve laughs, mostly at their family dynamic, something that hasn't changed between them all that much through the years, at least in their banter and humor. He's missed them. A lot.

Tony sighs and turns, opening the trunk of the car. He pulls out a large disc, then dumps the stuffed animal, crayons, and blankets off it, all of it Morgan's. When he does, it reveals the face of the disc — an outer ring of red around a ring of sliver-white, around another ring of red, then a blue circle with a silver-white star in the center. The shield.

There's guilt and tiredness in Steve's voice when he sees it. He sighs. "Tony, I don't know."

"Why? He made it for you." Tony flips it again, the back facing Steve so he can put his arm through it. "Plus, honestly, I have to get it out of the garage before Morgan takes it sledding." Grace chuckles.

Steve takes it from him, the weight of it familiar on his arm even after five years. "Thank you, Tony."

Tony nods. "Will you keep that a little quiet? Didn't bring one for the whole team."

Grace grabs a case from the trunk and closes it, asking, "We are getting the whole team, right?"

Steve nods. "We're working on that right now."

Grace immediately grins. "Oh, we're getting the band back together. This is great."

"You weren't even in the band the first time around," Tony points out.

"Well, I am now; I'm here, aren't I?" Grace replies, walking past Tony. He and Steve follow, the latter chuckling as they go.

Grace saw Nat first, and so greeted her first, excited to see her again, even if Nat laughed at her outfit. After getting Grace a pair of black leggings and a cuter shirt, she saw Scott again, and she greeted him in friendly manner, as she'd technically only met him the one time.

And then there was Bruce.

At first, she thought it was just the Hulk, but then he said, "Hey, Grace. Long time no see," in Bruce's exact voice.

Grace was sure she'd never been more confused. "What in the...?"

"You like it?" he asked. "I took the best parts of Bruce and the best parts of the other guy and just-" he used his hands to demonstrate, one being Bruce, one being Hulk, and then he put them together "- made them into one. So now... you get the best of both worlds."

"I don't think this is exactly the same thing that Hannah Montana did," Grace said, eyes wide, partly in shock, partly just confused.

"What?" Bruce asked. "I mean, no, but... cool right? Took me eighteen months in the lab."

Nat saw Grace's face — and Tony's, also noting how he hadn't said a single word since seeing Bruce for the first time — and she sighed. "You'll get used to it. Eventually."

"So you're not impressed?" Bruce asked, a bit crestfallen.

"Scientifically? Yes," Grace said. "This is just... very, very strange."

Tony nodded. "Yeah, what she said. I agree. Wholeheartedly. Very impressive but very strange."

Bruce smiled a little. "Thanks guys."

Then, Nebula and Rocket showed up, though Rocket didn't stay long. He took Bruce to go get Thor, while Nat went to get Clint, so the others tested Tony's time travel tech in the meantime, beginning construction on the machine they'd need to travel in time.

Nat got back with Clint first, and Grace could tell that what had happened hit him hard. Nat previously told her that his whole family had disappeared in the snap, and she hurt for him, especially after seeing the hardened expression on his face. He gave her a tight smile when he saw her, one that didn't reach his eyes. "Hi, Grace."

"Hey," she replied, hugging him, though it took him a moment to hug back. She hoped it helped.

When Bruce and Rocket finally got back with Thor, he was very different too. Most noticeably, he was incredibly out of shape, especially considering his physique in the past, and his hair, including his beard, looked very unwashed. Above all that, though, he had a sense of sadness around him, one it almost seemed he was trying to mask with humor and... well, alcohol.

He certainly wasn't in a good place.

Grace still smiled at him. "Hey, Thor." And, even though he smelled — he really needed a shower, at least — she hugged him. "I've missed you."

After a moment, a bit of shock, he hugged her back. "Hello, Grace... You've gotten... older."

She pulled back. "Yeah, well, I'm twenty two now."

He chuckled, shoving her on the shoulder in a friendly manner, though it was quickly obvious to Grace at the time that he was still plenty strong. "Ah, you're just a baby. A slightly taller baby, but a baby."

They continued building the time machine, Tony and Bruce (though mostly Tony) directing everyone else. They also made a time travel suit, and Scott tried it on. They had to make five more, seeing as six people were meant to go — that's all they had the Pym Particles (what would allow them to actually time travel) for, excepting one, though originally two, test runs. Scott screwed that one up, but Clint ended up doing the test run they had left, and it worked.

They can do it. They can really do it. It seems more possible now that it ever has before, and not just to Grace, who holds the pendant on her necklace often. Everyone they've lost, all those they've mourned over.

After five years, they can finally bring them back.
