Peter has spent the past week searching for Caitlin/Killer Frost, but nothing has turned up and Fox is still out of town.

But he did however leave Peter something new in his suit display. It's a suit he called the Velocity-Spider. It is a red and gray armored suit that includes unique looking silver visors for the eyes, as well as more defined plating and a glowing blue spider symbol that apparently glows in the dark, which isn't exactly useful for stealth.

Blitz features are the signature power of the Velocity Suit. When activated, it boosts the wearer's speed and allows him to use his momentum as a weapon, making it the perfect weapon to use against Savitar.

His computers suddenly alert him that there's a sudden wave of cold in the atmosphere.

Killer Frost is on the move, and so is he.

-

"Her name is Tracy Brand." Barry tells the team at Star labs on the information from the future. "She's one of the world's top theoretical physicists, or at least she will be."

"Girl Scout earns her merit badges. 2021 nobel prize, Copley medal, presidential commendation." Cisco lists.

"She's a genius yes, but what's that to us?" Joe wonders.

"She's the key to stopping Savitar. Future me said that four years from now, she invents the technology that traps Savitar in the Speedforce." Barry explains to him.

"Four years too late." Joe states.

"Yeah, except he did say that Peter would be able to help create it sooner, but after he left, we don't exactly talk in years." Barry says.

"So, we just need to find Tracy and make things up to Peter and we can save her." HR recaps their mission.

"Yeah, but that's gonna be difficult since Peter wants nothing to do with us." Cisco reminds them as he searches for Tracy. "Tracy Brand, currently enrolled in CCU theoretical physical program."

"So our hopes of defeating an evil speed god hinge on a grad student?" HR asks. "Could he worse." He admits.

"Let's go." Barry says and they leave to find her.

-

HR, Cisco and Barry leaves and go to CCU and head towards her labs.

"Ah, the soul sucking fluorescence of academia." Cisco says walking through the halls.

"Yeah, this is exciting. It's like meeting Norbert before he was Einstein." HR says, getting his name wrong. Or that could be his name on Earth-19.

"Albert." Cisco corrects him.

"Norbert Albert?" HR asks as they find her labs only to find Peter has beaten them to Tracy.

"Peter?" Barry questions.

"Speedy?" Peter questions back. "Cisco? Drumsticks? What are you guys doing here?"

"Who are you people?" Tracy asks.

"I'm Barry Allen. We would like a moment to talk with you." Barry explains.

"Well, I was kinda talking with her right now, Barry." Peter tells him.

"Peter, we're after the same thing here." Barry reminds him.

"Are we?" Peter asks when his senses alert of something and he looks to the door across the room starts freezing and shattering.

"Admission here is so easy." Killer Frost tells them as she steps into the room wearing a new outfit.

"That's why I'm here." Peter says as Frost shoots a icicle at Tracy and Peter quickly webs the icicle with a experimental fire webbing that Fox created for cold climates, cold situations, and cold metas, as it melts the icicle.

"Look who got new toys." Frost tells Peter.

"Get her out of here." Peter tells Barry and the others as he gets ready to fight Caitlin. Not something he's looking forward to. "So I see you've gone full Killer Frost, nice suit. I'll give you that much." He tells Frost.

"I got tired of those pencil skirts." Frost quips.

"Oh, now you're making quips. You know, if you weren't trying to kill me, I'd see if we could make this relationship work between a cold hearted villain and a warm blooded hero...but I made a promise to help you. Both of you." Peter says before creating a webbing of a firewall behind him so Frost can't reach Tracy before she sends a blast at him, causing him to be knocked unconscious and Frost makes her escape.

Barry goes around the building to find Peter unconscious and Frost is gone.

-

Barry brought Peter to the medical lab to help rest off the attack and when he woke up, Barry returned to talk to him.

"I'm not coming back to the Save Iris Group." Peter warns Barry without even looking at him.

"Right. Your sixth sense alerts you when I'm near." Barry reminds himself forgetting that power half of the time.

"I have been so focused on changing your future, I was blinded by the fact I was cementing Caitlin's future into becoming what I promised her she wouldn't become." Peter says while looking down at Caitlin's belongings that are still here after the incident that are still here.

"Listen, Peter, when you left, I traveled to the future and saw what happened to us. I never apologized, or made up for what happened. And that caused us to drift apart." Barry says and Peter finally faces him. "My future self explains to how we should be working together to fight Savitar, but when it comes to the people we love, we do that on our own. Focus on who we love." He explains to him.

"So you're saying you're done asking me to help you save Iris in the long run?" Peter asks him.

"You focus on getting Caitlin back, and I'll make sure Iris doesn't die. What do you say? Ready to fight a god together?" Barry asks of him and raises his hand.

Peter can agree to that and shakes his hand. "Team Spider-Flash." He agrees. "So. Where are we at with Tracy?"

-

They tracked Tracy to Jitters and they've sent HR to talk to her and to convince her to help them and Peter is on standby wearing his new Velocity-Spider and prays that Fox was right about it improving his speed to match Barry's.

HR and Tracy leave Jitters as their drinks freeze solid.

"Guys, we need a little help here!" HR calls when a a sphere flies towards Tracy and is interrupted by Peter speeding in and catching it.

"Lucius, you're getting a raise." Peter promises himself.

"Spider-Man?" Tracy asks looking over his new suit.

"Get her out of here." Peter says as Barry joins him.

"Caitlin. Please, stop." Peter begs of her.

"So you're Savitar's lackey now?" Barry asks of her.

"More fun to reign in hell and all that." Frost replies before she starts making a ice slide which seriously reminds Peter of Frozone from Incredibles.

"I'm gonna have her head back this way. When she comes back, you use one of your web gadgets and you two can work it out." Barry promises, remembering the agreement and speeds off after her.

Frost looks and sees Barry chasing her as she's after Tracy but Barry keeps them safe as they head back towards Peter who seriously doesn't want to do this.

But before he could even get the chance to, Frost sends a giant mist of ice at him and Barry pushed him out of the way, ending up with him going flying and Peter hitting his head.

Frost creates another icicle in her hands and walks towards Barry and leaves Peter.

"Savitar says I'm not allowed to kill you, but I can't have you following me around." Frost says and walks up to Barry. "It was the right leg last time, right?" She asks, remembering their first attack when the icicle gets knocked out of her hand once more and she looks to see Peter is back up. "You're seriously becoming a pain, Spider." She states.

"Yeah, I've heard that before." Peter states as he's holding his side from the push it got injured. "Caitlin, you need to stop this isn't you."

And what if you're wrong?" Frost asks him.

"Then kill me." Peter dares as he walks up to her and take off his steel mask to face her. "You have put your life in my hands countless times. That's how we first met. I saved your life, remember? It's time we reverse the roles. If I'm wrong, and you're not the woman I know and love, then kill me."

"Don't think I won't." Frost warns him.

"Then do it." Peter tells her and watches the struggle going on in Caitlin's eyes again.

For a brief second, they went from ice blue to the dark brown eyes he loves before they returned to ice blue and she blasts Peter just to push him, not to hurt him and leaves them.

But all that did for Peter was prove he was right, Caitlin is still in there and is still fighting.

"So this is where the Flash and Spidey goes down?" Tracy asks in Star labs. "It's not exactly what I imagined, but it's cool. So I always wondered how you kept the friction from building up a lethal dose of static charge."

"Yeah, the suit is vulcanized Teflon. It neutralizes any electron imbalance." Cisco says.

"And the White Which. I'm guessing you know why she's after me." Tracy guesses.

"She's teamed up with a villainous speedster from the future, and you build the technology that stops him." Peter explains still wearing the Velocity-Spider.

"Where'd you get the new suit anyway?" Barry finally asks him.

"I now have a wardrobe of outfits to choose from." Peter admits to him. "But this one is seriously hot and the mask is itchy. I don't know how all those knights did it."

"That's cool." Cisco states, hearing he has more outfits.

"Anyway, back to the topic, he wants to kill you before you build it." Barry explains.

"And have Killer Frost live up to her name so Caitlin can never return." Peter finishes.

"Killer Frost? Her name is Killer Frost?" Tracy asks.

"We know it's a lot to take in." Joe says.

"To be fair, you're basically telling me I'm Sarah Conner in Terminator." Tracy informs them and they're all skeptical on that error.

"More like Miles Dyson in Terminator 2." Miles tells her.

"Or even John Conner in any of them." May states.

"That works, too." Cisco agrees.

"So you're telling me my ideas about the...Speedforce, being able to control it, manipulate it, all of that were correct?" Tracy asks.

"It appears so." Barry says and shows her the information from the future. "Look, Tracy, we need your help. We need you to build this trap now."

"What happens if I don't build it now?" Tracy asks.

"There will be no stopping Killer Frost for starters." Peter tells her.

"And someone is going to die." Joe says and looks to Iris and Tracy excuses herself.

"I got this one." HR promises and leaves to talk with her.

-

Later, Tracy went to the park with a statue she admires they found from her hologram pictures and HR went to talk to her and she was just scared about this and he talked to her and she's ready to go at it.

"You know, since he's a god of speed, why doesn't Savitar just finish her off himself now he's free?" Peter finally asks.

"Let's just be glad he hasn't done that yet." Cisco states.

Peter can agree to that but he still wonders why when his phone goes off and see it's May. "Hey, May, what's up?" He asks as he answers.

"I talk. You listen." The voice of Killer Frost leaves the phone and now Peter's getting worried. "In an hour, you're gonna get a message with an address. Bring me Tracy Brand, or I will kill your precious aunt." She warns him.

"Caitlin, don't do this." Peter begs when she hangs up.

"What was that?" Miles asks and Peter just grabs the mask for his suit and races off.

Peter speeds through the streets and combines that with his swinging to avoid pedestrians and cars to make it to May's apartment and sees that Frost froze off the door from its hinges and must've taken her by surprise.

-

"So you're saying that if we don't turn Tracy over to Killer Frost, she's going to kill May?" Cisco asks as Peter is pacing around the cortex in fear.

"And if she does kill May, there is no way she is going to come back from that." Peter states not wanting to loose the two most important women in his life at once.

"Correct me if I'm wrong, but Tracy is our key to stopping Savitar, right?" HR reminds them.

"Yes, but what are we gonna do? We gonna just let Frost live up to her name and kill May?" Cisco asks.

"Not if I can stop her first." Peter promises.

"No ones gonna die, all right?" Barry promises. "Peter, were gonna get them both back, I promise you that."

Peter's phone goes off and he takes a look to see that it's May...well, Killer Frost.

"That's them. They're at the old Dressler Factory." Peter tells them.

"Okay, we know where they are. So what do we do?" Cisco asks.

"I have a plan. Just depends on how long miles can be invisible for." Barry says.

"How long do you need?" Miles asks.

-

At the Dressler Factory, May was zip tied to a chair in the middle of the room with Frost pacing around the room waiting for them to show up.

"You know, he hasn't stopped believing in you." May tells Frost who stops at the sound of her voice. The voice of the caring woman who has lost just as much as Peter and still believes in the good of people; just like him. "Yeah, even when everyone believes you're gone, Peter is holding onto hope. You know how he is. He's a hopefulist. I know it's not a word, but you know what I mean."

"Stop talking." Frost warns her.

"Or what, you going to kill me? I'm your only leverage to get them to come here. Kill me, you have nothing." May states and Frost is impressed by how well she's doing this. "I've watched a lot of movies with Peter and know how these situation works."

"I can freeze your lips shut." Frost dares with mist floating in her hands.

"Then why didn't you do that when you first took me?" May asks her as the icy mistress walks up to her. "You're strong, Caitlin. But everyone has their breaking point. And when we reach that breaking point, we need someone. You have someone who isn't going to stop until you are safe. This life is nothing but people hunting you down and trying to end you."

"The Spider can believe whatever he wants, but I'm not going back." Frost states when they finally show up. "Look who finally showed up. Hand her over." He tells them.

"You don't have to do this." Barry tells her.

"Yes, I do." Frost replies.

"Why? Because Savitar commands it?" Barry asks as he walks towards her. "You're..."

"Family?" Frost once again finishes.

"We protect each other, till the end." They both say and they're seriously confused.

"Savitar told me everything you'd say. You two are more alike than you realize." Frost tells Barry. "You see, that's how Savitar knows every move you're going to make. He's always one step ahead of you, because this is all history to him. That's how I know Cisco is in the rafters right now." She says and holds a detonator remote and the roof explosion when Miles and Cisco come down on a web.

"That failed." Miles states as Frost freezes Joe's gun and Barry speeds May out and Peter raises his hands.

"You think your webs can stop me?" Frost asks him with an arm raised.

"Wrong suit." Peter tells her and sends a dart out and she dodges it.

"You're full of surprises, Spider." Frost states.

"I'm here to help you, Caitlin." Peter promises.

"Caitlin is dead."

"Not to me, she's not. I know you're in there, Cait. And I'm never going to stop believing in you." Peter promises and Frost sends a blast of ice at him that he quickly speeds around and punches her across the room.

Seeing she's knocked unconscious, Peter runs up to her and takes off his mask.

"I love you, Caitlin." Peter says as he takes a sample of her blood in the process when his suit alerts him of a approaching speedster and Savitar appears and doesn't seem to notice Peter.

"My ascension is nearly at hand, heroes. As I rise, you will fall." Savitar promises them before Peter speeds up behind him and pulls out an inertron blade, the strongest material Fox could find, from his suit and stabs Savitar in the back, causing the god to cry out in pain before speeding off with the blade embedded into his neck as he takes Caitlin with him.

-

"I don't know how we keep surviving these things." Cisco states as the team reverses returns to Star labs.

"How did she even know we were up there?" Miles wants to know.

"Yeah, and how she knew exactly what I was going to say. That was weird." Peter agrees with him. "That was percist. Like Savitar was watching us. He knew what he was doing."

"He must've taken Caitlin so he could use her for something else." May guesses.

"Well, now I have a sample of her blood, when Fox gets back he can work on a cure to help save her." Peter promises.

-

After everything Barry thinks of the events that have occurred and realizes everyone was right.

There was no way Savitar knew exactly what he was going to say, what they were going to do by just remembering it...he was there.

Barry knows who he is.

He races off to an empty street and just waits a minute until Savitar suddenly appears.

"I know who you are." Barry tells him.

"It's about time." Savitar says.

"Yes, it is. Everything with you is about time, isn't it? The past, the present, the future. You know all of it, right? And you know everything about me! About Joe! About Wally. About iris! About Cisco, Caitlin, Miles, May and Peter. You know our strengths, you know our fears. You know how much we love each other. And you know how to use that love against us. That's why you took Caitlin, so that Peter would distance himself from the rest of us. But that blade...when he stabbed you, you didn't see it coming because that wasn't supposed to happen. Peter wasn't supposed to be there. All this time, we thought we couldn't stop you because you were one step ahead, but that's not it! You don't just know what's gonna happen to us. You were there. You lived it. You remember, when you were me." Barry finishes.

Savitar kneels down and the suit begins to open to reveal Barry Allen, and his face is burnt from the speed he's running at which is why he wears the suit and Barry can even see a scar on the side of his neck from Peter's blade.

"Like Peter said...we do like to play god." Savitar tells Barry as the two stand face to face after all this time.
