Barry speeds up to Savitar and tries to make it in time when a blast comes in and throws Savitar off and Barry speeds to grab Iris as she falls but is alive.

"What?" Barry asks as he turns to see both Frost of Earth-2 and Cisco with their arms stretched out.

"Looks like we arrived just in time." Frost-2 tells Cisco.

"Whoo! And not a minute too soon." Cisco agrees.

"NOOOOO!!!" Savitar cries out before speeding lad knowng if Iris dies now, it'll be too late. The timeline has changed.

"Sorry it took me so long." Cisco apologizes as Barry engulfed Iris into a hug. "I had to get to Earth-2, find Harry, get him to tell where Frost was. Get to there, fight a few Symbiotes and then fill her in on what's going on here and get here."

"You saved her, Cisco. That's all that matters." Barry says, happy they did it. "Wait, where's Peter?"

-

Peter and Killer Frost were still fighting in the forest as Peter wraps his legs around Caitlin's neck and tackles her to the ground.

"Who knew you'd be so straight forward in public." Frost flirts with him and she blasts him off of her and slams his head against a tree and drops to the ground. "Bye-bye, Spidey." She says and gets ready to kill him, but can't do it.

"Go on, Cait. Fulfill your destiny. Strike me down with all of your anger, and take your rightful place next to a god who's using you, and your journey to the dark side will be complete." Peter dares as he sees Caitlin isn't going to kill him.

Their moment gets ruined by Savitar speeding in with the bazooka.

"Keep him alive." Savitar tells her.

"What?! Why?" Frost asks him.

"Because I need him to build something for us." Savitar explains and speeds the two of them off. He now needs a new plan now that Iris is still alive.

-

Barry and the team return to Star labs and sees that they changed the future.

"So, we did it?" Joe asks.

"We did it!" Cisco cheers after he dropped Frost back on Earth-2 as she couldn't stay with the Symbiotes still around.

As they're celebrating, Fox comes in and sees them all happy.

"Lucius?" Barry questions. "Where were you?"

"I was working on something that's going to help Caitlin. I was kept up to date from Peter on what's happening, don't worry." Fox promises.

"Okay, I'm once again lost on this time travel stuff. What happens to Savitar now that Iris isn't dead?" Joe asks.

"Iris doesn't die, Barry doesn't become the same future version of himself he met. He never creates time remnants to fight him and Savitar is never born." Cisco explains to him.

"So once the timeline starts cementing, he will...vanish. It's gonna take some time for it to cement." Fox adds on.

"And as soon as it does, he's going to go full Marty McFly at the end of Back to the Future." May finishes.

"And how long will that take?" Joe wonders.

"Depending on how big the paradox is how long the timeline takes to cement." Fox tells him. "Adding to the Back to the Future reference, it took days for Marty to start vanishing, but in the sequel it was almost instantaneous how the past and future changed. My guess would be a couple of hours at best."

"He could do a lot of damage in a few hours." Joe states.

"And has anyone seen Peter?" May finally asks.

"Savitar must have had a backup plan for in case this didn't work. He stole the bazooka for something. He's been planning this for centuries. He wants to be a god, so he must need Caitlin for whatever he has planned." Barry takes a guess.

"Anyone have any good news?" Joe wonders.

"Well, I have this." Fox says as he pulls out a small vial.

"What...is that?" HR asks him as he flips his drumsticks around.

"This is a cure for Caitlin. Had to go talk to Caitlin's mother and did some research on her father, but this will rewrite Caitlin's meta-DNA. It will even them out so Caitlin can have control again." Fox explains as Wally speeds back.

"I searched the forest. Savitar and Caitlin were gone. No sign of Peter except for a bunch of dissolving webbing." Wally breaks to them.

"Savitar has them." Barry guesses.

-

Savitar stops and drops Peter, sending him toppling across their lair.

"Oh. You better have a plan C, because I don't think plan B is going to work at all." Peter tells him.

"Fix this." Savitar tells him, referring to the bazooka.

"You want me to fix the Speedforce bazooka?" Peter asks him. "I didn't make it, I just manufactured the parts. I had nothing to do with build it. I don't know how it works." He informs the Two Face looking friend of his.

"You know enough about it to alter what it does." Savitar knows.

"Oh, you don't want a prison maker. I have an idea. How about something that's gonna fix that burnt thin crust pizza of a face you have." Peter mocks him.

"An inter dimensional quantum splicer." Savitar informs him on what he wants.

"A splicer?" Peter asks, confused to what he's saying.

"I open a time portal, exposing the Speedforce, you shoot me with it, and I become fragmented throughout all of time. The past, present, and future. After that, the paradox can't kill me." Savitar explains to him.

"You want me to splice your soul throughout every moment in time. I'm pretty sure Voldemort had the same idea with the horcruxes, and we know how that ended for him." Peter quips.

"I will exist throughout every minute and rule the world from the Big Bang all the way up to the end of the world." Savitar finishes.

"That's why you didn't finish us off. You knew you needed this, and only we could create it." Peter finally realizes.

"Tracy Brand trapped me in the Speedforce in the future. All I had to do was get her to build it a little earlier and have my friend and all the adjustments." Savitar replies.

"I'm not your friend. I'm not building anything for you. And you know I don't break, so why don't I just sit here and wait to see how accurate Back to the Future was to how we're erased." Peter asks him and Savitar starts vibrating his hand and tries to threaten Peter and sees he's not going to break.

"Maybe you won't break. But she can." Savitar says and points to Killer Frost. "You know what I'm remembering? Fox has just returned to Star labs and he has a way of helping her. He can turn her back. You can have the woman you love back. You're so close. But you can't when she's dead. So either you put that brain of yours to work, or you loose her."

Peter looks and sees that he's stuck in a corner. If he works on it, then Savitar is going to rule the world all throughout time and space. If he doesn't, that means he looses Caitlin for good.

He then starts getting to work on it.

-

Barry is in a parking garage and is waiting for Savitar to come in.

Savitar does come and is across from Barry.

"I wasn't sure you'd come. Must be an off sensation, getting new memories. You having an uncertain future." Barry tells him.

"What do you want?" Savitar asks him. "I'm busy."

"Doing what? Getting erased from existence?"

"We will see which one of us gets erased."

"Are you still planning on becoming a god?"

"Peter and Caitlin are still alive. If that's what you're worrying about."

"I know. You need them for something. To pull off your grand ascension."

"Look, Barry, if I wanted to talk to myself, I could have done that, back at my lair. What...do you want?"

"I want to help you. You don't have much time, before the paradox reaches you. Come back to Star labs. Let Peter and Caitlin go, and let us figure out a way to save you."

"You really think I'd trust you?"

"You showed up. So you remember me coming here. Did I have any tricks up my sleeve? Was I planning on blindsiding you."

"I don't know. Maybe I get off on watching you grovel."

"No, I don't think that's it. I think you're hearing me. I'm still in there. Deep down, buried beneath the scars and the pain, that part of you that...it must feel so lonely. But it also knows what it's like to have a family, to have friends. You can have all that back. We can stop hurting each other. I remember when I was six, and I begged Mom and dad to let me go to the Science Expo in Midway. And we got a flat tire on that dirt road, so we were towed to that garage in a tiny, one street town. Of course, we were stuck there all day. Then we got ice cream and French fries at that little diner, and that night, we watched the local firework show, and...it turned out to be a great day. That's my favorite memory of Mom and dad. What was the name of that town?"

"Masonville." Savitar says with emotion.

"I'm still in there. Come home." Barry asks of him.

-

Peter was working on the Speedforce bazooka and can't help but keep looking over to Caitlin.

"You should be working on that, instead of looking at me." Frost tells him.

"You know that he's just using you, right?" Peter informs Caitlin.

"I'll take my chances." Frost assures him.

"Why are you taking chances with the enemy here?" Peter asks and drops his tools. "I'm willing to do anything for you, and you chose to follow the false-prophet who offers the exact same thing. I'd die because I love you."

"You love Caitlin." Frost reminds him.

Peter walks towards Frost as she looks away from him. "Caitlin, Killer Frost. You're both the same, I already told you that. Two sides of the coin who don't know how to face the other. So instead of facing, you both turn away and fight for dominance over the one body you both share." He states and turns her to face him slowly and takes her hand before placing it on his chest.

"The only reason I'm fighting is because this is beating, and it only beats for you, Caitlin. I trust you with my life. And you had the chance to kill me in the woods long before Savitar showed up. You didn't take the shot when you had it. You had multiple chances to kill me and you never tried to do it. Because I know deep down you still love me. Because I still love you. Caitlin is still in there, I know because when I look into your eyes, I don't see a cold blooded killer. I see someone who's begging someone to understand her, and I do. Instead of fighting each other, you should be working together."

Frost looks up to his eyes and the two just start to lean in close before they start to passionately kissing. The two stay like that for a second before separating from each other.

"In all honesty, I thought your lips were blue by design. You wear blueberry lipgloss?" Peter asks Frost and she actually chuckled at that.

Frost actually smiles, a genuine smile at this man who somehow is able to thaw her frozen heart and she realizes she couldn't hurt him if she wanted to. She does love him. The reason she joined Savitar was because he told her that he left team Spider-Flash and given up on her. But that seems to be just a lie.

She quickly separates from him when Savitar returns from blowing up Star labs using the philosopher stone.

"How'd it go?" Frost asks.

"As I expected." Savitar tells her. "I was a fool to think otherwise."

"What did you do?" Peter asks him.

"I got rid of a problem. A few of them." Savitar says and Peter knows he went to Star labs. "Is it ready?"

"Yeah, it's done." Peter says.

"Do it." Savitar tells Frost, meaning it's time to kill Peter.

Frost starts to become skeptical on the path she chooses as she gets ready to kill him.

Peter closes his eyes and knows it's coming. But he doesn't miss the battle he can see in Frost's eyes on wether or not we should kill the man she loves.

Yeah, Frost admits it. She loves Peter.

Before she could do anything else, Peter's senses go off and a breach opens before Cisco steps out.

"Cisco?" Peter asks before Cisco opens a portal and they get away.

"What was that?" Savitar asks Frost. "I told you to kill him."

"He got away, what do you want me to say?" Frost asks him.

"It doesn't matter anyway. It's time." Savitar states and grabs the Speedforce bazooka.

-

In Barry's loft, a breach opens and the two of them escape and see the rest of the team are waiting for them.

"Oh, I thought something happened to you guys." Peter says and runs to hug May and he grabs Fox and starts running his nuckles through his head. "You are getting a double raise, my friend! Harry, when'd you get here?"

"I'm here to help." Harry tells them.

"Good. Because I know what he's planning and where he's heading, but I might need you to do something." Peter tells him.

"What do you need me to do?" Harry wonders.

"How do you look in red?" Peter wonders and that confuses them.

-

Savitar and Frost head to a opening in the woods.

"We have to hurry. I must become immortal before the paradox reaches me. Today, I become a god." Savitar says as he starts opening a time portal and returns to Frost. "This is why I brought you here."

The Black Flash/Zoom Time Wraith exits the portal and Frost starts atttackig him until she shatters him like glass.

"See you later, Hunter." Frost says.

"The one thing Black Flash can't fight...cold." Savitar says and gets into position and Frost picks up the Speedforce bazooka and shoots Savitar.

They watch as he starts duplicating over and over before something happens and they close in on each other and a flash of red lightning exits the portal and punches Savitar.

"I've been waiting a long time to do that." Jay Garrick tells Savitar who's now confused.

"You didn't actually think I'd actually help you become a god, did you?" Peter asks as he and the entire team has showed up. "I changed the polarity of the climbing arc, and then I turned the Speedforce splicer into a speedster skeleton key."

"Let's end this." Barry says.

"Me, Miles and Cisco get Caitlin, everyone else get the god." Peter tells them the plan and they split up as the speedsters all race the god.

As they're running, something Savitar didn't see coming happens.

The Velocity-Spider comes speeding in and punches him.

"How are you here?" Savitar asks the Spider-Man imposter.

"He's not." The voice of Harry Wells leaves the suit.

"Wells." Savitar realizes.

"Spider-Man has a lot more than just one costume. And just about anyone can wear the mask." Barry says as the four of them start racing after the god.

Savitar cuts down some trees to block their path but it doesn't even phase them. Barry leaped over it, Wells went around the left side. Wally went underneath it, Jay went around the right side.

Savitar leaps into the air and throws a bolt of lightning at the four of them, sending them flying.

With the spiders and Cisco, they're dodging Caitlin's attacks while Cisco is using his powers to get them around faster than Caitlin can see.

Peter finally sees his opening as Cisco opens a breach for him and Peter leaps through score kicking Frost to the ground and aims his web shooters at her.

"Go ahead, do it." Frost tells him and Peter lowers his shooters.

"No. What I told you earlier was the truth, I know there's good in both sides of you. This is your power, making it your responsibility. But this will help." Peter states as he reaches into his pouch that comes with his suit and pulls out the cure. "You wanna find a balance insidead of constant fighting, this is your chance." He tells her before tossing it at her feet and walks away.

Miles' senses go off as the god of speed returns to them. "Look out!" He shouts as Savitar throws Miles and Cisco away and once again Peter is getting strangled by Savitar's suit.

"You'll pay for what you did!" Savitar promises and Caitlin watches as the man she loves is dying and he doesn't have help coming for him. "And you can die twice." He states, remembering when Weather Wizard killed him.

Before he could kill Peter, Savitar gets blasted by a giant mist of cold and Peter looks to see Frost saved him as she walks up to Peter and helps him stand back up.

"I knew you didn't have it in you, Caitlin." Savitar says as the speedsters return and Barry quickly changes Peter into the Velocity suit. "I only have a few minutes left. I can feel it. But before I go, I'm gonna kill Joe. And Wally. And Iris. If I am going to die, then everything the two of you love is going to die too." He promises and turns to Cisco, Miles and Caitlin.

Peter speeds at him and with all of the power his suit could give him, he was able to go inside the Savitar armor and pushes Savitar out of his own armor.

Before anyone could realize what happened, Peter starts using his own super strength and webbing to destroy the suit from the inside and the suit explodes.

"No!" Savitar cries.

"How does it feel to come so close, just to end up on the ground!?" Peter asks of the false god. "You let the pain and the darkness determine who you became!"

"But we won't let the pain decide our destinies." Barry promises and the two of them then combine their speed and send two upper cut's to Savitar's chin, sending him flying before tumbling to the ground.

The two heroes watch as the unconscious monster starts to flake away and gets erased from existence.

Peter removes his mask and looks to Caitlin and smiles at the other before they run and Peter tosses his mask before he starts kissing Caitlin as they pull the other as close as they can possibly get to one another.

"I don't know if this is weirder or just uncomfortable." Cisco states looking at the two of them and they just ignore him as they stay there.

No cold entered Peter's face. No frost sucked the heat out of his body. There was just warmth, and the soft, familiar motion of Caitlin's lips against his own.

She was breathing heavily when she finally pulled back, her cheeks flushed pink. She smiled, rubbing a thumb over his lips. "I think I got some lipstick on you."

"I don't care." Peter breathed, leaning back down to kiss her again and wrapping her up in his arms as she holds onto him with all her strength as if she would loose him if she let go.

It had been months, but Caitlin Snow was finally back, and was finally home.

-

They had managed to loose Caitlin in the aftermath of Savitar's death.

Peter had to help Cisco dismantle the splicer, a sort of just-in-case precaution that Barry was all for taking. Caitlin had been right beside him, her hand resting on his arm, but when he looked up again she was gone.

No one had even seen her leave, and Peter felt a crushing disappointment that she wasn't staying.

Now it had been two days, and he still hadn't seen her. He was starting to get worried. He knew how self-destructive Caitlin could get when she was alone with her guilt and pain, something he was sure she had an awful lot of right now.

Outside the labs, Peter glanced away from him and was about to head in when his gaze caught a figure standing under a tree.

He, Barry, and Cisco walked down the grassy slope just as Caitlin came around the tree. She took off her sunglasses, smiling a little as the three of them approached her.

"Well, well, well," Cisco greeted. "At least you're not shopping at Villains R Us anymore."

Caitlin didn't seem to register the joke.

"Why did you come here?" Barry wonders.

Caitlin stared at her feet. "I don't know."

Peter tilted his head, wanting to reach out and hold her but restraining himself. "Maybe you're ready to come home?"

"I don't have a home," Caitlin murmured, shaking her head sadly. She finally looked up, making eye contact with Peter, and reached into her pocket. She pressed a small, blue vial into his palm. The cure. "Tell Fox thank you," she said. "But I'm just not ready to use this."

Peter rolled the vial to his fingertips and passed it back to her. "Keep it," he said quietly. "Just in case you ever want to use it."

Caitlin bit her lip but nodded, tucking the vial back into her coat. "I...I guess I came back to say goodbye."

"Caitlin-"

"No, you don't understand," Caitlin shook her head, shutting her eyes for a moment. "I...I've done things...become someone that-that I don't understand. I need to figure that out, and I-I need to make sure that in doing so, no one else gets hurt. You all trust me, and I know you'll trust me forever, no matter what I do. But I just don't trust myself, and I need you to understand that. I have to leave."

Peter swallowed, his throat suddenly dry. This couldn't be how it all ended. But he couldn't say a word.

Caitlin started to turn, but Cisco caught at her arm. "Caitlin-" he started, but his voice faltered.

"I have to go," Caitlin said again, and his hand dropped.

Finally, Peter shook himself. "Wait!" he cried, covering the few steps that she had already taken and closing the distance between them. "Stop, Caitlin, please."

"It's okay, Peter. This isn't forever. I'll...I have to find my own journey back to you." Caitlin promises him and pecks him on the lips.

"I'll wait for you to finish that journey." Peter promises.

"I could be gone a long time." Caitlin warns him.

"You are worth waiting for. I waited two years to be with you, I can wait a little while longer to be with you forever." Peter promises as she leaves the two of them standing there.

"You doing okay, man?" Cisco asks Peter as Barry's the first to leave.

"Yeah. Hey, you mind if I...I need some time to think. And I need to do something, I don't think I can do that here." Peter explains to him.

"Yeah, I'll explain to the team." Cisco promises and Peter walks away from Star labs.

This isn't forever, but this could be a while before he comes back. Besides, there's someone who needs his help.

-

Peter gets to New York the next day and called to give his friend a heads up before knocking on her door.

The door opens and Jessica Jones is there.

"Come to finally pick up your kid?" Jessica asks him.

"Nice to see you too, Jessica." Peter says and she lets him in.

"Told her you'd be here to bring her back. You sure you gonna do this?" Jessica asks as she closes the door.

"Yeah, I'm sure." Peter says as Frankie comes into the room. "Hey, Frankie. Was Jessica kind to you?"

"She was nice, yeah." Frankie says and walks up to him nervously. "I didn't think you'd be back for me."

"I don't abandon anyone. Jess, mind if I had the room?" He asks Jessica and she leaves. "Frankie, I've been thinking about something that I want to know your opinion on. What do you say you come back to Central City and I look after you?"

Frankie waits for him to say something to reveal this as a joke, but it seems there isn't one. "You serious?"

"I know how it feels to have powers at your age, how it feels to have nobody understand what you're going through. I've been where you are, and Jessica says that you've been doing well on controlling them. What do you say? Want me to look after you?"

Frankie smiles with tears of joy and just pulls Peter into a hug as her answer that Peter happily returns.

-

Five months later

Peter picked a bad time to cut losses from the team, the night that he left for New York, Barry was taken into the Speedforce prison because it needs an occupant after what he did with Flashpoint.

Cisco was left in charge of team Spider-Flash as Kid Flash and Vibe help fight the crimes and even the Spiders. But Peter doesn't feel like he should be at Star labs without Caitlin.

And apparently, HR's books actually took off so he's been on nonstop book tours.

Everything in the city was at least peaceful as the team are working on a way to keep the city safe and bring Barry home. At least until Peter turned on the news at his home. That's what he calls it at least.

It doesn't feel like home without Caitlin...

But he and Frankie has been able to become a custom to living with each other, she even met May who adores her.

Whenever he's out Spider-Manning, he knows Frankie can take care of herself both against people and just being home alone. But when he knew he would be out for uncomfortable amount of hours, Fox or May would look after her and stay with her or she would stay with them.

Peter's also more careful when he's fighting crime knowing there was someone who now relies on him, but he keeps the city safe just like before.

"The police found the entire warehouse of men were slaughtered this morning. Residents are advised to remain in their homes. The assailant appears to be armed, dangerous and wearing-" the news was saying as Frankie and Peter were eating breakfast, but Peter knew what they were going to say.

"A red suit." Peter finishes as he knows exactly who the man is.

"You know who that is?" Frankie asks him.

Yeah, Peter knew exactly who it was. Only one person wears red and black while leaving a trail of dead bodies.

Deadpool.
