New York City, outside
This is now the year 2023. Certainly, New York City was once a large hustle and bustle metropolis, which was caused by the Snap five years ago until it became abandoned, gloomy, and less crowded. The sudden disappearance of millions of people caused panic and chaos within the city. However, notable New York residents killed in the Snap which included April O'Neil, Casey Jones, Master Splinter, Baxter Stockman, Rocksteady, Stephen Strange, Wong, May Parker, and Peter Parker. Sometime after Thanos wiped out half of all life in the universe, New York City was largely abandoned. Survivors of the Decimation began to form communities outside the city, including a makeshift marina on Liberty Island. Citi Field, which had been left unused as the Snap made the New York Mets stop playing, now held a therapy group formed by survivors, including Steve Rogers. And in the past five years, the victims of the Decimation would be known as the Vanished. Despite the destruction caused by the Mad Titan, the world was slowly recovering. Anyway, inside a largely abandoned part of Manhattan, Leonardo, Silver, and Luna are in Times Square. Sonic, Lincoln, and Raphael in Lower Manhattan. Jet, Knuckles, and Lola at 9/11 Memorial Museum and the plaza that is next to the One World Trade Center. However, in the past five years since losing their family and friends, Lincoln, now 16 years old, which he became Leni's age, Luna is 20 years old, and now Lola is 11 years old, which was Lincoln's former age, which would reveal that Lily is now 6 years old. And the turtles are now adults after their sensei turned to dust, his sons go their separate ways after moving out of the lair three years ago. For starters, Leo resides at the New Avengers Facility. Donnie inherits Tails' Lab for his technology to be created. Raph still lives in sewers. And Mikey inherits Mr. Grouse's house while he is gone from the Decimation.
Leo: (depressed with a sigh) Another gloomy day at a time like this in the city.
Silver: Let's not give up hope yet! We still got landmarks to maintain.
Luna: I sure hope what Cap's doing in his group session with the survivors of the Snap.
Silver: For some reason half of the city's population is still around, but not the other half.
Sonic: (on comms) We wouldn't count on that if we were you! (somewhere in Lower Manhattan with Lincoln and Raph) All the boats are around the Statue of Liberty.
Raph: No enemies were around since the last time we fought the Foot.
Lincoln: Or Dr. Eggman.
Sonic: Since Knuckles and his crew took the vibranium back from Eggman.
Luna: No wonder how he got to Wakanda. When you guys were looking for the Avengers for clues.
At the 9/11 Memorial Museum. Jet, Knuckles, and Lola looking around at the semi-crowded landmark.
Lola: Since Sonic had obtain the vibranium shields when Cap dropped them and left.
Jet: We didn't know there were any treasure around the country.
Knuckles: Certainly, the vibranium belongs to the Wakandans for some reason they use for weaponry, spinal wounds, and use Kimoyo Beads for communication.
Lincoln: (on comms) Speaking of communication! I wonder how Cap is doing with his session therapy lately?
Sonic: Same here!
Inside an abandoned cafe, with a poster on the wall labeled "WHERE DO WE GO, NOW THAT THEY'RE GONE?". A therapy session is taking place with Steve Rogers and seven other people.
Grieving Man: So I, uh... Went on a date the other day. It's the first time in five years, you know? I'm sitting there at dinner... I didn't even know what to talk about.
Steve: What did you talk about?
Grieving Man: Same old crap, you know? How things have changed, and... my job, his job... How much we miss the Mets. And then things get quiet... He cried as they were serving the salads.
Starlin: What about you?
Grieving Man: I cried... just before dessert. But I'm seeing him again tomorrow, so...
Steve: That's great. You did the hardest part. You took the jump, you didn't know where you were gonna come down. And that's it. That's those little brave baby steps we gotta take. To try and become whole again, try and find purpose. I went in the ice in '45 right after I met the love of my life. Woke up 70 years later. You gotta move on. Gotta to move on. The world is in our hands. It's left to us guys, and we got to do something with it. Otherwise... Thanos should have killed all of us.
San Francisco, day
A self storage facility with a sign saying "U-STORE It, SELF STORAGE", inside the facility, there are some stuff and junk where Luis' Van has been impounded after the Decimation. However, a rat inadvertently presses some buttons, which activates the portable Quantum Tunnel in the back of the van, where Scott Lang, also known as the Ant-Man came out of the Quantum Realm. His objective was to extract the healing particles for Ava Starr, who goes by the name Ghost for her condition. Unfortunately, Hope van Dyne, better known as the Wasp, and her parents, Hank Pym and Janet van Dyne disappeared after Thanos snapped his fingers, leaving Scott stuck in the Quantum Realm for the next five years, until now. But thanks to the rat, Scott is now released from the Quantum Realm.
Scott: (takes off his helmet and checks his surroundings) What the hell?
He manages to stand up, as another electrical failure sparks out of his gauntlets, and now looks around in a confused look.
Scott: Hope?
Inside a security office, a security guard is seen reading a book as he looks upon his security screen, seeing something going on in one of the storage facilities. In the cameras, it shows Lang in his casual clothing, shouting, waving a sign with the word "HELP" written on it.
Outside the facility, he pulls out a pushcart and looks back seeing the guard giving a stern look from far. He walks around until reaching his hometown, finding a post filled with MISSING posters, abandoned houses, a wrecked car, nothing but desolation. He then sees a kid in a bike pass by.
Scott: (calls to the boy) Kid! Hey kid!
The kid stops his bike as he stares back in a serious look.
Scott: What the hell happened here?
The kid still stares at him and is almost about to tear up, but immediately turns away from him and move on. Lang still gives the same confused look, as he arrives in somewhat a memorial called "THE VANISHED", with all the names of the people who became victims of the Decimation. As Lang arrives on one of the engraved stones, he immediately drops the handle in shock.
Scott: No. Please. Please, please. (moves on to check the other side of the engraved stone) No, no, no. No. (Lang excuses aside a young couple as he keeps on checking another engraved stone if his daughter's name is on one.) Excuse me, sorry. No, Cassie, no.
The camera keeps panning and switching as Lang checks the rest of engraved stones if his daughter's name was in one.
Scott: (desperate) Please, please, please, please... No, Cassie.
Lang looks at the engraved stone in shock, revealing his name in it. Thus the stone makers put his name in by mistake knowing that he was alive the entire time.
Scott: What?
In the suburbs
Scott is now seen running across the memorial, then to his hometown, only to ring a doorbell at his house, bang on the door, and try opening the door, but is found locked. Then, he sees a feminine figure appear out of a hallway inside. The figure gets closer, revealing a woman in a purple sweater, with her hand pushing towards the glass door's window, and her face filled with amazement, as she unlocked the door. It was Lang's daughter, Cassie, now a grown-up teen since the last five years.
Cassie, who hasn't seen him for five years, holds up his face in an emotional sight and starts to smile tearfully. Scott does the same.
Scott: Cassie?
Cassie: Dad? (Both of them emotionally hug each other as both dad and daughter had reunited. Then Lang shoves her back, realizing that his daughter is now a full-grown teenager.)
Scott: You're so big!
Both dad and daughter share a hug once more.
Scott: Cassie! Hope is gone! And so are her parents!
Cassie: Oh, no! Not them too! I hope you could bring them back!
Scott: I sure can do, Cassie. I'll go to Cap and see if he'll get things up and going.
He and Cassie hug again before the daughter could say.
Cassie: Good luck, dad! Bring them back safely!
Scott: See you soon!
Most importantly, I have added extra scenes in New York, which included the therapy session scene where Steve was telling the grieving people to move on from their past lives until the bitter end.
