Peter was running around the city, keeping the people safe while Barry was working on getting faster to catch the newly named Reverse Flash. They were both afraid of the criminal and what he can do. But they're going to train harder so they can stop him and not put their loved ones in danger.

At a car containment building, the door starts getting frozen over and a car comes ramming into the door, shattering It. Leonard Snart and Mick Rory, his new partner with the heat-gun, exit the car.

"Told you It would break." Snart states to Mick.

"And the shrink says I'm crazy." Mick states to himself. "What is this place?" He asks Snart.

"Customs warehouse. Imported cars from Europe, all worth a fortune." Snart explains and Mick removes the covers on the cars and sees the bran new vehicle.

"Question. How do you suggest you and I drive all these cars out of here?" Mick questions seeing they didn't bring any vehicles except the one they rammed.

"We're not. We're not stealing anything." Snart answers.

"What are you talking about?" Mick asks now believing he truly has gone crazy.

"Our entrance set off the silent alarms. The cops will be arriving in two minutes and 14 seconds." Snart starts explaining the plan since Mick doesn't exactly have the brain to ask him the plan.

"Bring them." Mick states and goes for the case with the heat-gun from the car.

"That's not for the cops, as we discussed." Snart warns him as he sits against the cars. "He'll be here." Snart states, talking about the Flash.

Outside, Spider-Man got word of what's happening and is following the police cars to help with the criminals.

Back inside, Snart starts hearing the sirens and is getting confused. "You do hear that, right?" Mick asks him.

"He's not coming." Snart realizes and they start leaving. Seeing they won't be getting their fight they were hoping for.

"Seatbelt." Snart warns mick and they escaped.

-

Later the police show up to see what's happened. "Are you sure nothings missing?" Joe asks the officer.

"That's what the supervisor said." He explains to Joe. "I can check again." He offers as Barry is doing his thing.

"Well, the breakage indicates the door somehow had zero viscoelasticity when it hit the ground." Barry explains and they don't understand. "I'm sorry. The steel shattered like glass." Barry explains and looks over the pieces of the door. "It was frozen, Joe."

"Snart." Joe states.

"I thought Snart was some world-class thief." Eddie states. "All these expensive cars...he didn't take any of them?" Eddie asks and Barry was thinking the same thing.

"Eddie, put out an APB on Snart." Joe tells him and he leaves to do it.

"Snart wasn't here to steal anything. He was setting a trap for me." Barry tells Joe.

-

"Captain Cold is back?" Cisco asks as Barry fills them in what's going on.

"For a non metahuman, Leonard Snart is proving to be quite the nemesis." Wells states to them.

"Doesn't he still have the cold-gun?" Peter asks them. "Because If prefer not to go against that thing with round 2." Peter states, hating normal cold, let alone a gun that can give you frostbite easily.

"Well, what does he want this time?" Caitlin asks him.

"The Flash." Barry answers them. "If Snart wants a fight with the Flash, then I'll give him one." Barry tells them and Wells disagrees. "You don't think I should?" Barry asks him.

"I didn't say that, but as fast as you are, you cannot be everywhere at once. And it becomes a question of priorities." Wells explains to him. "Now, in the last month, you have made a commitment to increasing your speed, enhancing your reflexes, and it's working. You're finally getting faster."

"Okay, but I can't just ignore Snart." Barry states to him not wanting another chance of someone else dying.

"Last time you fought with Snart, a train derailed. You were lucky to get all of those people to safety. Now if you don't give him a fight..." Wells explains and Barry understands.

"He might just back off, and there'll be no casualties."

"Look, Barry, Cisco and I will work with Joe and the police and devise a way to catch Cold. Yes, I said it, Cisco. As soon as it came out of my mouth, I heard it." Wells realizes and Cisco just smies that his name is spreading.

"We can easily devise a way to stop Snart." Cisco tells him.

"Yeah, and I can upgrade my suit to be able to melt the ice or something I already have a heater installed." Peter offers.

"Whether or not you go after Snart, that's your choice. We here, we will do whatever we can to support it." Wells tells Barry. "But after this past Christmas, after the events with the Reverse Flash, I just think he poses a greater threat to all of us."

-

Cisco and Peter came up with an idea that can keep the police safe and they brought the prototype to the prescient to see if they'll take it.

"Excuse me, can I have you attention?" Cisco asks while all of the police are looking his way.

"You have their attention, Cisco." Peter states to him and Cisco Just chuckles nervously.

"Okay, check it. So, dr. Wells, dr. Parker and I, we took your ballistic shields and we lined them with a pretty sweet compacted heating ribbon designed to repel temperature attacks, especially those reaching absolute zero, like Captain Cold's gun." Cisco explains to them.

"And that's supposed to stop us from turning into popsicles?" One of the officers asks them.

"In a nutshell, yes." Peter tells him.

"How we supposed to trust anything from S.T.A.R. Labs after you nuked the city?" A different officer asks and they knew that would come up from someone.

"You're right, you shouldn't trust us." Cisco tells them. "What happened a year ago, that was our fault. And we can't change the past, as much as we wish we could. But tomorrow is a different story. We just want the chance to make things better." Cisco explains and aims his ice gun and shoots the shield and the police watch as the ice on the shield quickly melt away and they're impressed.

"Dummies are one thing. My officers are another." Singh warns them and they understand and he leaves.

"Looks like we did a good thing today." Peter states and smiles to his friend seeing he's got some cred back and leaves to S.T.A.R. Labs to work on his suit for the fight.

-

Caitlin is also at S.T.A.R. Labs and is looking at anything related to Firestorm. She was so focused, she didn't hear Peter coming in and touching her shoulder and she jumped.

"Sorry. Didn't mean to scare you." Peter quickly apologized.

"No, it's okay. I was just focused on something." Caitlin says and Peter looks at what's she's looking at.

"Firestorm. Isn't that what Ronnie said before he vanishes?" Peter asks her.

"Yeah. I've been looking over everything to find anything that could help with him, but theres nothing." Caitlin states and changes the subject. "So, What brings you here?" She asks him.

"I'm here to give my suit's heaters some upgrades like I said last night to withstand the cold temperatures. I don't wanna repeat of the last time I fought Snart." Peter explains to her.

"Yeah, even with your radioactive blood, you almost got permanent frostbite, so it's a good idea." Caitlin states to him and sees something else is bothering him. "You sure nothing else is bothering you?" She asks.

Peter thinks for a minute and goes for the straight answer. "I'm terrified." He states and Caitlin is surprised at him. He's never admitted to being afraid before. "The Reverse Flash threatened May. And I'm not as fast as Barry to be able to save her if he goes after her. And I don't know how to tell her she could be in danger without telling her about Spider-Man." Peter explains the predicament to his friend.

"Why don't you just tell her?" Caitlin asks him. "I mean, you told us pretty easily." Caitlin explains to him.

"If I told her, I don't know how she's going to react, and if I remember correctly, you passed out when I told you." Peter states and she sees his point. "I know I have to tell her eventually, but it's been over a decade and I still haven't been able to tell her. I just want to keep her safe."

"Maybe telling her will make her more safe." Caitlin explains to him. "I mean, if she knew her nephew was Spider-Man, she would know you'd never stop until she was safe. Sure, you fight criminals and super powered people, but that's because you choose to." Caitlin tells him and he understands what she means.

"I'll think about it." Peter says and starts getting to work on the upgraded and gets an idea. "Wait, Cait. What if Firestorm isn't a word?" Peter asks him and she doesn't understand. "What if it's an anachronism for something? Like a scientific idea." He explains and Caitlin sees where he's going with it and retypes F.I.R.E.S.T.O.R.M.

"Fusion Ignition Research Experiment and Science of Transmutation Originating RNA and Molecular Structures." Caitlin reads outloud.

"That's a mouthful." Peter tells her happy to have helped. "Wait, I've seen this research before." Peter realizes. "It talks a lot about altering the structure of an element by unzipping the atoms, and rebuilding it to create a new element. It was written by Martin Stein, and co-written by Jason Rush, who's a grad student here at Hudson university. So if we want information, he's the most likely to have it." Peter explains to her and she gets happy.

"Thanks, Peter." She tells him.

"With or without the mask, I help those who need it." Peter replies and then starts getting to work for real.

-

That night, they got word Snart is planning on stealing a painting resembling fire and ice. And let's be honest, when you buy something that's basically half white and the other is red for over a million dollars, you've got too much money.

The Rathaway's are leaving their plane with the painting as they speak as Snart approaches them. "Somebody better call 911." Snart tells them, hoping the Flash will show up this time.

As time passes, the police approach with Spider-Man and his cold-resistant suit. Snart shoots his cold-gun and it has no effect on any of them.

"Mick!" Snart shouts and the police and Peter see his partner.

"Who's he?" Peter asks, completely confused now. "Why do they call you people the heat?" He asks them. "I'm the heat!" He shouts and shoots them with his heat-gun and they can't protect themselves against that.

"Forget them, Mick. Get ready for him." Snart says and Mick isn't listening as he's loosing control over himself as he keeps burning. Peter sees Mick's more focused on the cops than him, and uses it as an opening to shoot a taser web, causing his gun to short circuit.

"We go, now!" Snart tells him and shoots Peter before he could stop them. The cold doesn't hurt him, but the blast still hit him across the room. "I hate Snart." Peter states as Snart and Mick escape.

-

Peter went to S.T.A.R. Labs to have Caitlin check up on him after the fight and he's perfectly fine despite the light bruises and a bit of s sunburn on his chest.

"Thanks, Cait." Peter thanks her as she finishes.

"No problem, Peter." Caitlin tells him happy to help. "So, what happened?" She asks

"Snart has a new partner with him. He had this handheld flamethrower. I wasn't able to counterattack that." Peter tells her.

-

At their hideout, Mick and Snart think about what to do now they have the painting. "The bug's webb fried the secondary internal fuel chamber." Mick explains as he fixes the gun. "It could've been worse. You were right to get me to learn every part and circuit of this thing." He states as Snart comes up completely angry. "Repairing It was...a snap." Mick says as Snart raises the cold-gun at Mick and he raises the heat-gun on Snart.

"Give me one good reason I shouldn't kill you right now." Snart asks Mick.

"It's gonna be hard to find someone else to listen to your winning speeches." Mick replies to Snart.

"You lost it out there," Snart tells Mick, "just like the last job. You lost focus, became obsessed."

"I'm obsessed? What about you?" Mick asks Snart since he's been obsessed with the Flash for months. "What about you? You're usually counting the seconds, gig the whole thing planned out. But all you care about now is the Flash."

"We have to put him down. With him gone, that leaves Spider-Man and he's useless against these weapons." Snart states to Mick.

"We got the finger painting. It's worth millions. It's ours. We're rich, job done." Mick counters seeing no point in going after someone faster than the two of them.

"What about the next job, Mick? With weapons like these, no one can stand against us, no one except the Flash." Snart explains then lowers the cold-gun. "If you want out, take the painting and go." He tells Mick. "But if you want Central City to be outr home where we can do and take whatever we want...this is our chance...your chance." Snart explains and Mick just turns to the painting and burns it with the gun.

"Very motivational." Mick states about the speech and is in with the plan of taking down the Flash. "How do we get him?" Mick asks Snart.

"Flash and Spider-Man aren't so different from us. They have partners too." Snart states and remembers the people who saved them the first time.

-

Caitlin went to Jitters to get what he could from the co-author of the paper Peter found and he explained to her that Martin Stein was the leader behind the project and he's been missing ever since the accelerator. And that the army showed up and took everything related to their research so there's nothing that could help her find Ronnie and she leaves to her car.

As she's heading to the car, her phone rings and she sees Peter's name on the screen and answers it. "Hey, you get anything that could help with Ronnie?" Peter asks her.

"No, but you were right about the research. But get this, a day after the accelerator, the army confiscated everything related to F.I.R.E.S.T.O.R.M." Caitlin informs him on what she found.

"Okay, if the army is involved, this could be more serious than we thought."Peter states.

"Yeah, that's what I was thinking. I'll tell you about it more later, see you." Caitlin replies, but before he could reply a blast of ice hits her car door.

"Caitlin, what was that?" Peter asks heading the commotion from the other end. Caitlin turns around slowly and sees Mick and Snart.

"Car trouble?" Snart asks and Peter recognizes the voice as Caitlin screams and tries getting into the car and Mick grabs her.

-

"When the heat-gun was fried, it increased the surrounding temperature of the air dramatically, sort of like an extreme heat wave." Cisco explains at S.T.A.R. Labs to Barry and Wells as they're unaware of what happened and Cisco gets a name for Mick. "Heatwave."

"Stop doing that." Wells exclaims at him.

"Okay. I measured the temperature output of both the cold and heat guns, right? And while the cold-gun achieves absolute zero, the heat gun successfully reaches absolute hot, or the hottest temperature an object can achieve." Cisco keeps explaining to them.

"So potentially, these two guns could cancel each other out." Wells realizes seeing where Cisco is going.

"Yes, but to do that, you'd have to make them cross streams." Cisco explains when they hear something slamming in the halls.

"You mean like in Ghostbusters?" Barry asks him as Wells turns to check on the noise.

"That film is surprisingly scientifically accurate." Cisco realizes and they turn to see Peter in his suit and out of breath and he pulls off his mask.

"You alright there, man?" Cisco asks him.

"He..he took Caitlin!" Peter tries talking through gasping for breath after running from his apartment all the way to S.T.A.R. Labs.

"Who took Caitlin?" Wells asks when Barry's phone goes off and he answers it and speeds off.

"I was talking to Caitlin on the phone when I heard Snart talked and she screamed and she must've dropped it or something." Peter explains to them.

-

Barry makes it to the crime scene and sees Caitlin's car and calls out for Joe. "There's no sign of Caitlin." Joe explains and Barry now blames himself because Snart got her to get to him.

"We have to get her back." Barry states to Joe.

"Damn right. Come on, let's go." Joe replies and they go to find her.

-

At the prescient, Eddie approaches them with some news about Snart's partner. "We got a hit, a second pair of prints. Belonging to a Mick Rory. A big time arsonist. He and Snart worked a job last year that went bad." Eddie explains and hands them the file on him. "Half of Rory's body was burned in a fire that got out of control. He escaped from the ambulance on the way to the hospital, hasn't been seen since." Eddie tells them and is still confused.

"Why would they kidnapped someone like Caitlin?" Eddie asks since he doesn't know she works with Flash.

"Joe, Thawne, it's on every channel." Singh states and turns on the tv's and shows Caitlin being held hostage with Snart and Rory holding her back.

"Greetings, citizens of Central City. I am Leonard Snart. But you can call me Cold." Snart tells them.

-

At S.T.A.R. Labs, Peter is watching the same broadcast and his anger is growing. "I'm gonna make this simple for everyone. That read streak you've been hearing whispers about, the one mysteriously saving people these last few months with Spider-Man? Well, surprise, he's real. Calls himself the Flash. Porter and main, tonight, sundown. Show the whole world you're real." Snart says and Peter knows that's where Snart wants the fight and he's serious. "And Spider-Man, if you decide to make an appearance, this woman dies." Snart warns Peter and the camera goes dead.

"Hang on, Cait. We'll find you." Peter whispers, hoping she can hold on until they find their location. From what he could see in the background, they were in some warehouse.

-

At their hideout, Mick is tying Caitlin into the seat with a bomb strapped underneath. "You're a friend of theirs, huh?" Mick asks Caitlin. "He's fast." He states and lights a lighter. "Like fire. Fire, it's undefinable. Heat, light, energy. It's an evolution when things burn."

"You're sick." Caitlin states angrily, hating she's being used against her friends.

"Maybe you're the sick ones. You ever think of that?" Mick asks her and Caitlin disagrees and sees his scars.

"You've got third-degree burns. Why didn't you get skin grafts?" Caitlin asks him.

"The fire revealed my true self, showed me who I really am." Mick replies. "I wonder what the Flash will reveal when I burn his skin off. Maybe afterwards, I'll roast a spider." He states and that makes Caitlin's blood boil. Peter's been there for her whenever she needed him, if he dies because of her, she'll never forgive herself.

"Do whatever you want to me, but leave them alone." Caitlin states through her teeth.

"Ooh, you and these heroes must be pretty close if you're willing to die for them, hmm?" Mick asks her and grabs the heat-gun. "You want me to show you who you really are?" He asks her and aims the gun towards her head and she starts getting scared.

"Mick." Snart interrupts him. "Time to go." He tells Mick and he activated the bomb under the chair.

"You better pray the next people that come through this door is us." Mick warns her and puts a cloth around her mouth to keep her quiet.

-

At S.T.A.R. Labs, Barry is waiting for his time to get to the fight when his phone rings.

"Okay, you're up." Joe tells Barry. "Barry, after tonight, everyone's going to know that the Flash exists. You ready for that?" Joe asks Barry and he isn't sure about it and hangs up.

As Barry gets into his suit, he goes into the halls and Peter is there in his suit. "Okay, we clear on the plan?" Barry asks Peter.

"You keep them busy, me, Joe and Cisco locate Caitlin and get her to safety. It's not a complicated plan." Peter states, since he was the one who had the idea.

"Okay, let's do this." Barry says and speeds off.

-

Porter and main, Snart and Mick show up and wait for Flash to make his appearance. Barry comes speeding in and is ready to fight. "The scarlet speedster. Any preference on how you'd like to die?" Snart asks him. "The flame or the frost?"

Barry doesn't say anything and walks towards them. "Not in the mood for chitchat. Gotcha, ready when you are." Snart states and they warm up their guns and Barry's eyes flicker with electricity and they beigin their fight.

Snart freezes the road and explodes a firehydrant and freezes up the explosion.

Barry runs and slips onto the ice sending him through the water, causing it to shatter.

"Barry you okay?" Wells asks him from S.T.A.R. Labs. "You know what you need to do."

"Yeah, get them to cross their beams and cancel their guns out. I know." Barry replies from behind a car. "Not as easy as you would think." Barry states.

-

Peter and Joe are moving in on a location Cisco pinpointed for them. "Are we sure Caitlin's here, Peter?" Joe asks him as they move towards the warehouses.

"Starting from Caitlin's car, me and Cisco were able to piece together surveillance footage that lead us to this general area." Peter explains and activated his heat signature software to do its thing.

"There's over a dozen warehouses here. How do we know where to start?" Joe asks Peter.

"Well, my scans indicate that only one of these places has heat on for about the past few days. And I jags a feeling Snart's hotheaded friend likes things hot." Peter explains and they move towards the warehouse and see the doors are locked.

"This is definitely the place." Peter states and grabs the lock with his bare hands and shatters it.

"You watch my six, my senses will handle the rest." Peter tells Joe as they walk through the warehouse.

"Caitlin, you here?" Peter asks and hears someone whimpering. "Caitlin, is that you?" Peter asks and his mask gets her behind the cases.

"Stay here, I'll get her." Peter tells Joe as he leaps on top of the shelves and sees her.

"Caitlin." Peter calls out and she looks up to see him. "I'm glad to see they didn't hurt you badly. Okay, is there anything I should be concerned about?" He asks her and she tries saying something, but the gag is preventing her.

"Okay, That was a stupid idea on my part, just nod your head where." Peter states and she nods downward and Peter sees the bomb. "That's not good." Peter mumbles since he knows nothing about bombs but remembers what Oliver taught him about land mines.

"Caitlin, I'm gonna need you to remain calm and trust me." Peter states, not wanting to explain what he's about to do and she looks confused. "You trust me, right?" Peter ask her and she nods her head and he puts his plan into action.

Please shoots a web at the ceiling and knows that if he's not precise, he and/or Caitlin could die. "I hope Oliver taught me right." Peter states and swings down and grabs Caitlin's chair and that sets off the bomb, but Peter got them far enough away so they didn't get hurt, but it burnt the webbing.

"You good?" Peter asks her and she's terrified. "It's gonna be okay, we got you." Peter states as Joe comes up to them and sees she's okay.

-

Back at the fight, Barry is trying all he can, but he can't get their beams to cross. "I can't get them to cross streams. Speed isn't getting this dome." Barry explains to Wells.

"You're right. Maybe the way to do this is not by going faster." Wells realizes and Barry understands.

"It's going slower." Barry replies and starts running slowly towards the two of them and they shoot him with their beams. Barry just takes it and moves closer until their lined up and speeds off and the beams finally cross causing them to blow Mick and Snart backwards. Snart reaches for his cold-gun and Barry stops him.

"I didn't see that coming." Snart states. "I guess you win this time."

"There won't be a next time." Barry states and Eddie, who tried helping during the fight, came up to arrest them. "Thank you, detective." Barry says, discarding his voice before speeding off to see if Peter did his part.

-

At the prescient, Snart and Mick are being brought through for processing as Mick screams about how he'll burn everything and everyone.

"You're partner's a real hothead." Joe states to Snart.

"That's funny." Snart says while fake laughing.

"You know what's hilarious, Snart?" Joe asks him. "We got you."

"Congratulations." Snart replies non-enthusiastically and they take him away.

"Nice work, Eddie." Barry congratulated him.

"It wasn't me. It was the Flash." Eddie admits while he hands the head and cold gun to Cisco.

"We won't be needing these for trial." Eddie states and Cisco promises he will destroy it.

-

Peter makes it to S.T.A.R. Labs to check on Caitlin after the events that's occurred. "Hey, Cait, you doing okay?" Peter asks as she's just staring at the computer and it's off.

"Yeah. I guess." Caitlin replies to him and Peter doesn't believe her. "All things considered, I knew you guys would find me." Caitlin reassures Peter.

"You know, this is exactly why I kept my identity from you. Everyone who learns my secret gets into trouble." Peter explains to her.

"The reason I was safe was because I knew my friend would rather die than give up on me." Caitlin assured him and he agrees he would always put his friends first. Maybe that's another reason that he should've told everyone a long time ago.

"Also, thanks for the quick rescue." She states and gets up to give him a hug. Peter retaliates and hugs her back.

"I'll always be there for all of you. No matter the time, place or reason." Peter replies to her.

"That's why I know I can rely on you, Peter." She states and breaks the hug.

"Look, Cait, I won't be able to get much sleep knowing people might actually know who you are, you mind if I just kept my eyes on you for tonight?" Peter asks and she knows he's just looking out for a friend.

"Sure, just for tonight. I can take care of myself, you know." Caitlin agrees, hoping he doesn't make a big fuss.

"I know you can, but I make no promises." Peter states as they get ready to leave for the night and she just laughs at his reply.
