Y/N's P.O.V

We head over to time machine in our new white suits and I've got my original Spider-Man suit underneath.

I need it for the mission as I was wearing in 2012. Though I did have to make some adjustments to it.

I don't want my younger self getting any future suit ideas.

Steve tells me he wants me to boost the team's morale for this mission by giving a speech to the other's.

Y/N: Three years ago we lost. All of us, we lost friends, we lost family and we lost apart of ourselves. Today we have a chance to get it all back. You know your teams, you know your missions.

We all put our hands in the middle.

Y/N: Get the stones, get them back.

Steve: We have one round trip each, no mistakes, no do overs. Most of us know where we're going. That doesn't mean we should know what to expect. Be careful and look out for and each other.

Y/N: We have to work as a team to get this done. United we stand, divided we fall. This is the fight of our lives, and we're gonna win.

I look at Tony and Steve.

Y/N: Whatever it takes.

Tony and Steve look at me with a smile.

Steve: Whatever it takes.

Tony: Whatever it takes.

Cap looks to everyone.

Steve: Good luck, everyone.

We all spread out a bit.

Rocket: They're pretty good at that.

Scott: I know right.

Leonard: Very inspiring.

Tony: Alright you heard 'em. Stroke those keys Jolly Green.

Steve looks at me.

Steve: You are getting good at the speeches.

I smile at him.

Y/N: Well, I learnt from the best. You taught me how to be someone worth following, Steve.

He chuckles.

Steve: That's good, because once this is over, they'll be following you.

I tilt my head.

Y/N: What does that mean?

Steve smirks.

Steve: You'll find out.

I look over to see Rocket talking with Clint.

Rocket: You better bring that ship back in one piece.

Clint: Yeah, yeah, yeah. I'll do my best.

Rocket: As promises go that kinda sucked.

Nat looks to us.

Natasha: See ya in a minute.

I look around and see Steve, Tony, Ben Bruce and Bucky on one side and Natasha, Clint and Snart on the other.

The machine then activates.

We all activate the helmets on our time travel suits.

All of us look around getting ready for what's about to happen.

We all shrink down and go into the quantum realm and head off to our respective time periods.

(New York, 2012)

Third person perspective

The year is 2012 and the Battle in New York has started.

This is the battle in which the original Avengers formed for the first time to defeat Loki and his alien army called the Chitauri.

Y/N's P.O.V

Myself, Steve, Bruce, Tony and Scott exit the quantum realm we find ourselves in New York the year 2012.

When we show up the original Avengers are fighting the alien army, the Chitauri.

Once we land on the ground are time travel suits dissolve off our bodies.

Cap and I moves forward before looking back to the others.

Steve: Alright, we all have our assignments. We got two stone uptown, one stone down. Stay low and keep an eye on the clock.

We hear a roar and then turn to see 2012 Hulk smashing his way through everything.

I look to Bruce.

Y/N: And maybe you should smash a few things along the way.

Bruce nods and rips his vest off and starts lightly smashing things.

Bruce then heads of to find Dr. Strange and get the Time Stone.

Steve, Scott, Tony and I get the Mind and Space Stones from what will become Avengers Tower.

(Fifteen minutes later)

We're all at what will become Avengers Tower.

Tony is in position outside to update us on what's going on.

Tony: Alright, boys, things look like there about wrapped up here.

Steve: Got it. I'm approaching the elevator now.

Y/N: I'm in the stairwell. Cap, what's you got the scepter, give me the signal and I'll come get it.

Steve: Copy that.

I fly in silently and see my past self and the other's standing around.

As they move around I spot 2012 Cap in his old suit.

Tony: Oh, Mr. Rogers, I forgot that suit didn't do anything for your ass.

Steve: No-one asked you to look, Tony.

Tony: It's ridiculous.

Y/N: I'm with Tony on this, Steve. Your ass didn't look great.

Steve: Thanks, Y/N.

Scott: I think you look great, Cap. You ask me that's America's ass.

As I'm standing around I see Rumlow's S.T.R.I.K.E crew come in with Jasper Sitwell.

(Five minutes later)

Y/N's P.O.V

So, I've just gotten the scepter from Steve.

My younger self is currently helping Cap with search and rescue.

Tony should've gotten the Cube by now.

I walk around the corner to the nearby walkway.

Y/N: Tony, talk to me. Tell you've got that Cube.

I stop when I see someone infront of me.

Y/N: Ah, you gotta be shitting me?

I see my 2012 self standing infront of me.

Y/N 2012: I've got eyes on Loki, Cap. Fourteen floor.

I put the scepter case down.

Y/N: I'm not Loki. And I don't wanna hurt you, kid.

Y/N 2012: I don't buy that.

He rushes forward and throws a punch, but I grab his fist with ease.

I force him back and he slides across the walkway.

Y/N: You've still got alot to learn, kid.

He looks at me.

Y/N 2012: Now, I'm gonna kick your ass.

He charges at me and we fight.

I'm mainly just defending myself as I don't wanna hurt him.

As we fight we knock the scepter down and fall down after it.

We hit the ground a few levels below the walkway.

I stand up and see him pick up a picture.

The picture of me with my birth parents.

Y/N 2012: Where the hell did you get this?

I go for the scepter, but he quickly jumps up and gets me in a headlock.

We fall down to the floor.

Y/N: Natasha... is... your sister.

He let's me go.

Y/N 2012: What?

I quickly hit him and grab the scepter.

I then turn and hit him with the scepter, knocking him out.

After that I grab my picture and stand up.

I look down at my fourteen year old self.

Y/N: Sorry, kid. Just know you're gonna take worse beatings than that along the way, but you'll be okay.

I then leave to meet up with the other's.

(Ten minutes later)

???: Hey, Y/N.

I turn to see Tony and Scott in a scrapped car, with Steve leaning against it.

Tony: We've got a problem, buddy.

Scott: Yeah, we do.

Tony and Scott explain what happened with the Tesseract.

Y/N: Well, what are we gonna do now?

Steve: I don't know.

Tony: Hey cut me some slack, guys. I just got hit in the face with the Hulk.

Scott then starts freaking out as he says we don't have any other options.

Tony: Wait, I think I know how we can get more Pym particles.

Y/N: How?

Tony gets up and comes over to Steve and I.

Tony: A little trip down memory lane. Camp Lehigh.

Steve: When were they there?

Tony: Well, I have a vague idea.

Steve: How vague, Tony?

Tony: I remember coordinates.

Steve: Now, we need to get the Tesseract.

Just then I remember something Fury told me back in 2016.

Y/N: I know how to re-take the Tesseract.

Tony: How?

Y/N: Fury once told me that my birth parents had the Tesseract in their possession and got it back to Fury two weeks after I was born and two weeks before they died.

Cap looks down.

Y/N: Anyway, in 1998 the Tesseract is sitting in my parents house and I know the coordinates.

I start putting in the coordinates.

Tony: Okay, we'll get some Pym particles from 1975, and after that we'll come to the year 1998 to get you.

Y/N: Got it.

I give Tony the coordinates for where I'm going.

Scott: What are you guys talking about?

Steve: Well, I guess we're improvising.

I hand Scott the scepter.

Y/N: Scott get this back to the compound.

Steve and Tony start to put the coordinates in for where their going.

Scott: Steve Captain America Rogers. If you guys do this and it doesn't work, your not coming back.

Tony: Thanks for the pep talk, piss-ant.

Tony looks to Steve.

Tony: Do you trust me?

Steve: I do.

He then looks to me.

Tony: What about you, kid?

Y/N: Always.

I look at Steve.

Y/N: It's your call, Cap.

Steve: Let's do it.

The three of us activate our time travel suits and go back into the quantum relem.

Steve and Tony head to New Jersey, 1970. 

While I head to Queens, New York 1998.
