Kara, Alura, Mon-El, and Al are keeping people safe and saving them from falling debris as Morg'Ann and James evacuate the buildings.
Clark is currently on the other side of the planet dealing with these...planet-quakes as Myr'nn and J'onn make it to the location and get prepared.
"Our time is short, it seems." Myr'nn says.
"Give them all to me." J'onn asks his father. "Every memory. I can take it."
"We haven't the time. But there is one more I must give you." Myr'nn says and he gives J'onn the dawn of the Green Martin's and the first keeper of the sacred scrolls.
Back in the city, Morg'Ann slides across the ground and raises her shield as it takes the damage of falling debris and James goes inside to rescue someone's son who's inside.
At the DEO, Winn is putting out the fires that are starting from the ruptures in the building.
"Supergirl, Spider-Man, the waterfront's in trouble. And something's coming up." Mary warns them.
-
Peter and Kara were flying out and they look to see the Legionnaires are here.
"You didn't think I'd miss out on the fun." Imra says as she uses her powers to raise the water to stop If from reaching the city.
"Never though I could get to use this cold setting again." Peter says as he activates his lasers and they start shooting -100 degrees on the water and it comes together and stops heading towards the city.
"You're all clear, kid. Now let's blow this thing and go home." Kara quips.
"I assume that's some sort of film reference." Brainy guesses.
"Wait, nobody showed this guy Star Wars?" Peter asks as he flies next to Kara. "Not one of them? I mean, prequels sure, sequels I give or take. But none of them?" He wonders as Brainy shoots it and the water falls back into the ocean.
-
Myr'nn and J'onn say their goodbyes to one another and Myr'nn promises to always be there for J'onn before merging with the staff and saving the earth.
Reign starts to get crushed within the crust and all over the world, the tornados, tsunamis, everything stopped all at once.
The heroes all come together as they see that the damage is done.
They finally won, they saved the day.
-
They return to the DEO and J'onn comes back and now they wanna get some answers from the Legionnaires.
"How'd you know to come back?" Kara wonders.
"We got Mon-El's signal." Imra tells them. "The message from the time beacon."
"Mon-El said it broke on Argo." Alura remembers.
"It did." Brainy says as he approaches them. "The beacon had a failsafe installed, to send the message after being destroyed."
"Winn, did you track down the source of the terraforming?" Alex asks him. "Or Reign's location?"
"Peter's Mom is working on that." Winn says while pointing his thumb behind him, gesturing to where Mary is searching for them. "That is still weird for me to say."
"What about Sam?" Kara asks.
Sam is still asleep and is fighting Reign off from within her mind.
Brainy takes to Winn and Mon-El and told them that he can't go back to the future now that his relative, Brainiac, the evil one, is alive because of their changes. The future needs Mon-El to return and Winn to take his place among the Legionnaires.
"He wants you to go to the future?" Peter asks as Winn went to him and James for advice.
"I know, it's insane. And I-I don't know where to begin to solve a problem like that. I don't know what Brainy was thinking but he's malfunctioning." Winn states.
"Or he's thinking you're the smartest dude he knows." James guesses.
"Oh, and then there's this." Winn says as he pulls out a paper being protected in a casing.
"What's that?" Peter asks.
"Oh, you know, just a different design off of the same technology that Gwen used to create your holo-shield." Winn states. "Brainy brought it back from the future. Apparently, it's an artifact and the apparatus saved countless lives or something."
"Or something?" Peter asks. "Dude, Gwen could never solve how to create a shield to protect the whole body. If she did, she wouldn't have stopped at this little shield I use to block lasers." He says as he activates the holo-shield to prove his point. "You're a genius."
"He's right. The only person who doubts that is you." James agrees. "Question is, what do you want to do?"
"I made a shrine to, like a cup of dirt from the future." Win informs the two of them.
"That's weird." James comments.
"Agreed." Peter replies.
"Shut up." Winn tells the two. "You know, and actually going to the future, that's like beyond my wildest dreams. But, no, this is my home. I have you guys, and Kara, Alex, and J'onn. You guys are my family. That's...that's too hard."
"I took off my mask today." James informs him. "I...met this woman and her kid was in danger while she was panicking. I don't know if it was my eyes, or voice, but after I removed it she found her calm instantly. And that makes me wanna take off my mask all the time. It does feel too hard."
"Destiny is calling you, Winn. You gonna answer, or pretend you're not home?" Peter asks him.
The alarms start going off and they run to see Mary working on it.
"Mom, what's happening?" Peter asks her.
"It would seem J'onn J'onzz's ship is sending a distress beacon." Mary tells them.
"A distress call? Why would Selena do that?" Kara wonders.
"A trap? I'm just guessing." Winn says.
"Regardless, I've been able to access the ship's sensor. My craft is sitting near a great power source. I believe it might be the site of the terraforming." J'onn says as he looks over the information.
"But Sam is still unconscious. We need her around if we're going to stand a chance against Reign." Kara says.
"Actually, before you guys came back from Argo the first time, Lena learned she could end Reign, with a lethal dose of Kryptonite." James tells them. "She wouldn't do that when they were still connected, but now..."
"No." Kara interrupts. "We don't kill. Not even someone like her. There's got to be another way."
"Skirt, we cannot contain her. She's basically invincible to everything that should hurt anyone like us. The hardest lesson a hero learns is...sometimes, the thing that we never want to do, the thing that we took an oath to never do is the one thing we need to do for the greater good." Peter tells her, remembering he also needed to cross that line a few times. It never gets easier, and he tries to avoid it as much as possible himself.
"If all else fails, and we have no other recourse, I agree." J'onn says.
Kara sees their points and they get ready to head out to stop them and Reign.
As they left leaving, Sam wakes up and she has her powers under control.
-
The team enters the fortress and they see they've got the witches outnumbered by 2 to 1.
They all go running in and start fighting them off.
Al and J'onn make quick work of the elder witch and handcuffs her with ease using kryptonite cuffs.
"What is this, devilry?" She asks.
"A little piece of home." J'onn says as the others fought the other two.
Morg'Ann does a spin and smacks her shield in her face and Alura kicks her down.
Peter and Kara go and start to fight Reign off once more.
They take their fight to the sky and Peter webs Reign and slams her into the ground. But Reign isn't down yet as she flies back up to them and they slam into the Legionnaires ship.
The three go flying in and Peter is sent tumbling as Reign and Kara continue to fight.
Peter raises his last kryptonite missile in his arsenal and raises it to see Reign has Kara in a chokehold.
"Shoot it!" Kara tells him.
"I don't have a clear shot." Peter tells her since most of the kryptonite would be more likely to kill Kara then Reign.
"You cannot win. There is no prison you can build that can contain me." Reign tells them. "There is no one, no weapon on this planet of equal power that can kill me."
As if on que, Sam appears and stabs Reign, sending her falling and dropping Kara
Reign gets up and punches Sam away.
Seeing his opening, Peter shoots the missile and it hits Reign in the face, causing her to choke on it.
Kara gets up and quickly punches Reign while she was weak and she goes flying into the pit she was reborn from.
But she isn't down yet as Reign comes back up and starts randomly firing lasers everywhere.
Peter was the first to get hit as he didn't have enough time to activate his shield and the laser kills him.
Sam moves to avoid the laser only for her to be next to get hit and Kara watches as most of everyone gets hit by the laser and Reign dies.
Kara gets out from behind the rocks and sees the only other survivor was Morg'Ann who used the shield for cover.
Morg'Ann is clutching Peter's hand as he groans in agony.
"Peter!" Kara tells as she runs up to him.
"Hey, Skirt...heat vision is painful." Peter quips. "All these years of fighting, battling, I learned nothing. I came in, running blind."
"No, this...it's my fault." Kara tells him, knowing she came in willing to do anything to prevent his death like Thawne warned her...and now she's the one who caused it. "I came in here ready to kill her...I should have found another way. I lost track of what I stand for."
"There's another lesson in superheroing I never taught you." Peter realizes. "Sometimes, we don't have a choice. And sometimes...you do everything to find another choice. And sometimes you find...another one when it's too late."
Kara looks around and sees some Harun-El was in the room and then takes Mon-El's Legionnaire ring.
"The rock split them apart. It could put them together. There was a prison strong enough to contain her." Kara realizes and looks to Morg'Ann. "Stay with him, I have an idea." She tells him, not wanting Peter to be alone in case this doesn't work.
"Supergirl, did Sam get there?" Alex asks.
"She did, but we screwed up. I need you to find me a disruption." Kara tells them. "I need to go back in time, like the Legion."
"You can't breath in space." Winn warns her.
"I'm wearing Mon-El's ring, I can with it on. If I can turn back time, I could use the electricity in the Harun-El to take us to the Fountain of Lillith." Kara explains the plan.
"The pressure alone could crush you, Kara." Mary warns her.
"Just find me one, now." Kara pleads and then flies off into space where they found one and sees events of time reversing before her.
-
Kara opens her eyes and she sees she's back in Reign's arms in the chokehold.
Peter goes to raise his missile when she stops him. "Don't!"
"You cannot win." Reign tells them. "There is no prison you can build that can contain me. There is no one, not anything on this planet of equal power that can kill me."
Sam comes back and Kara flips Reign over her head before Sam could repeat the events.
"Throw me the Harun-El!" Kara tells Peter who picks it up and it burns his hand as he grabs it before tossing it to Kara.
"Shock us again in five minutes." Kara tells Peter before they go to fight Reign off in Sam's mind.
Sam finally gets revenge for everyone who Reign has hurt and killed or have tried to as she used the weakness fountain to kill Reign.
"What have you done to me?" Reign asks as demons from the place start to surround and consume her into ashes.
They wake back up and sees everything is alright and Reign is gone for good this time.
-
Peter finds Kara staring off into the night sky and joins her on the balcony.
"Whoo, this has been a rough few weeks." Peter states. "First, we fight Reign and I end up in a coma. Next, we find out our parents are alive. Then, I have a sister who wants to be a hero. Then Reign is defeated, she comes back, she tried to destroy the planet. We defeat her. She comes back. Then we banish her into Sam's mind where she's being attacked by...demons?"
"That about sums it up." Kara says and faces him before pulling him into a kiss, happy that he's alive.
Peter kisses back and they stay that way for a minute before he breaks it off. "What was that for?"
"Just happy you're okay." Kara explains, not wanting to say that he was supposed to die because Thawne said so. "You're strong for a non bulletproof being."
"Ha-ha, you're more powerful than me. We've established that." Peter says sarcastically. "Even though I could beat you if I wanted to."
"What was that?" Kara asks.
"Nothing." Peter replies and pulls her into a kiss this time and she happily returned it. "But honestly, we won. So why do you look so sad?"
"Before I went to Argo, I thought that I could be Kara Zor-El, ordinary citizen. That I would feel that I was home. But when we were fighting Reign and the witches, I had this moment...this realization Argo's not my home anymore. National City is my home. Earth is my home. And it's my job to protect it."
"Home is not a place, it is living among those who live and honor you." Peter quotes what Myr'nn told him.
"Yeah, it is." Kara agrees.
"When we first met, I didn't know what to think of you. It was...crazy to say nonetheless. I've met your cousin a dozen times and he never mentioned once mentioned a relative. I thought you were crazy to just jump in like that, saving a plane and me helping you out. But then I remembered myself, when I first did this. Nobody asked me to, nobody forced me to. My decision was because of what happened to my uncle. For years, my mind blocked that off from me. Told me I wasn't there when he fell...but if it wasn't for his fall, I wouldn't have rised up. These years with you, the ups, the downs, they've been amazing. I thought this life would start to dim your light like I did to me. You can only do this for so long before you question what you're fighting for. Or run out of things to fight for. But all I see is that your light is not only as bright as ever, but you gave me a reason to keep fighting. A reason to hope, and restored my light. You saved me, Kara Danvers, not Supergirl. With or without that cape, you're amazing." Peter tells her.
Kara smiles and wipes the tears away. "Okay, that's it." She says as she pulls him in again and kisses him and Peter chuckles under his breath at how the Girl of Steel has become soft around him.
"You two done over there?" Mary asks and they break apart and see their parents were watching.
The two of them just get nervous like two high schoolers who were just caught.
Winn agrees to go with the Legionaries back to the future to save the world.
J'onn promotes Alex and makes her the new director of the DEO so he can help people in the way of the Green Martian.
Lena gets the blood tests for Sam are finally normal meaning Reign is in fact gone for good.
-
They throw a party to say goodbye to Winn, Brainy takes his new place at the DEO.
Al, Mary, and Alura leave back for Argo and Morg'Ann stays behind with her brother.
And to top it all off, James told the world that he is Guardian and everyone is talking about the new Captain America that some people are calling Miss America.
"Do you think Winn's gonna make the Legion new outfits?" Kara asks Peter.
"You should see the designs that guy made for me. Some were red and gold, some were just seriously multicolored. No, I'm sticking to red, blue and gold." Peter tells her as the oven beeps, meaning dinner is done.
"Yeah, why did you add the gold?" Kara wonders.
"What, thought I'd paint myself to look like the American flag? Nah, I'll leave that to my sister, the new Captain America."
"That's another thing I've been meaning to ask, you're related to Captain America?!" Kara finally freaks out as everyone knows the super soldier from World War Two.
"Yeah, that was a reason I didn't really believe I was a alien years ago. I just thought that it ran in my blood. Then the other other powers manifested and I gave up on understanding them." Peter says as he drops the food on the island table.
"And where is your sister?" Kara asks, looking around.
"She wanted to do a bit more superheroing before turning in." Peter explains as he takes some plates and puts them down next.
Things are just gonna get a lot more stranger and they welcome anything to try and stop them.
-
Somewhere in the city, someone wakes up in a dark building and goes to stand up only to start crushing a metal pole in her hands as she looks and sees she's completely nude.
Grabbing the nearest cloth to cover herself, she walks over to a mirror and looks at her reflection.
She had short blonde hair that reached up to her cheeks on the left side of her face. The right side of her head had completely short hair that barely went past her head.
She reaches up and touches her cheek, not understanding what happened to her.
"Who...am I?" She asks as she looks at her other hand and it's sticking to the cloth she's using to cover her body.
"Who...why...why can't I remember anything?!" She asks as she panics and puts her hand to her forehead and backs up into more reflections and all she can see is herself.
But she has no idea who she's looking at.
She has no idea who she is, where she is, or what's happening to her.
But one word is repeating in her mind.
One thought.
One idea.
One thing repeating over and over.
Peter.
——————
No joke, my original ending was gonna be a double of Peter like Kara, except his would have a cyborg half. Think of a fusion of Peter and his suit, kinda like Cyborg.
But then I got the idea for this.
FYI, her design is based off of the Gwen from Into the Spider-verse.
