Peter is helping Joe fight off Alchemy's men as Barry is still being held up and Joe grabs his gun and Peter raises his web shooters trying to figure out what they're supposed to be doing.

"Shoot him!" Barry tells them.

"I can't see it." Joe says as even Peter can't see it.

"Just do it!" Barry says and Peter throws a web grenade as Joe starts shooting and the grenade gives them an outline on what Savitar looks like when Alchemy grabs the stone and starts trying to escape.

"Oh, no, you don't!" Peter says and tires webbing him but Alchemy uses the stone to vaporize the webbing.

"Let's go for a run." Savitar tells Barry and the two disappear.

On Peter and Joe's side, they were able to stop one of the followers from getting away but they turn to see Barry is gone.

-

Barry gets pulled out of a blue vortex and thrown onto the ground as Savitar appears to beat Barry down and brings him through the portal multiple times, making him appear in several different places.

Savitar finally throws him at the water front and looks at the beaten down speedster.

"Had enough?" Savitar asks Barry.

"Not even close." Barry sates standing back up but as soon as he runs at Savitar, he sends Barry flying after punching him so fast, when Barry got whiplash from the speed as he's getting thrown around constantly.

"Still alive down there?" Savitar asks Barry. "You are only a shadow beneath my throne. You are the past, where as I...I am the future Flash." Savitar informs him before grabbing him by the face and pulling out his blade again when a breach opens.

Caitlin and Cisco exit the breach and see Barry held up by a chokehold of what seemed to be air.

Caitlin bit her lip, hard. "I can't see it!"

"Just do it!!" Cisco yelled, on his knees with a hand at his head from the strain of creating a breach.

Caitlin lifted her hands, concentrated, and sent a stream of ice towards Barry's invisible foe. Soon enough, a shape began to form: large, hulking, and inhuman creature.

However, the ice cracked and there was a flash of white lightning before Barry crumpled back to the ground.

"Ooooh!" Cisco stood up with a groan, rubbing his head and taking off his goggles. "Whew-y! I'm gonna feel that tomorrow. That was a new and painful use of my powers."

Barry lay on his back in the pile of ice chips.

Caitlin walked up to him, followed by the hobbling Cisco, and helped him up. "You okay?"

"Yeah, I'm okay," Barry breathed, wobbling on one foot and a knee, hand still on the ground. "Just cold. Thanks for coming."

-

The team returned to Star labs and brought the Wally cocoon with them, not knowing what else to do and Caitlin started a quick checkup on the team.

"Barry, you're already healing; you should be fine soon. Uh, Cisco, the MRI that I did of your brain shows changes in the capillary morphology similar to that of a mini stroke," Caitlin recapped, coming over to stand by the bed where Cisco was lying, hand on his forehead. "I wouldn't try and inter-dimensional breach like that anytime soon."

"Okay, okay," Cisco said, sitting up with a worried look on his face. "You can't just gloss over that, okay? W-w-what does that even mean- am I gonna have this migraine for for the rest of my life?!"

Caitlin stared down at him, unamused. "It means that you should take a few Aspirin and you'll be fine."

"Oh," Cisco huffed. "Well, just...lead with that, next time."

"Peter, you should be perfectly fine. Just a few bruises from being thrown around like that." Caitlin assures him.

"Thanks, Cait." Peter replies happy. "And we know the risk you took with using your powers."

"I didn't do anything." Caitlin tells him.

"You saved Barry's life, possibly mine." Peter informs her.

"You've saved mine plenty of times. I'm sure I still owe you." Caitlin tells him. "I'm gonna go check on Wally."

"I'm gonna ask the obvious question...What was that thing?" Peter asks Barry.

"I don't know." Barry tells his friend. "But now we know Alchemy is just the lackey. Whatever that thing was, it's what we're really up against." He says as they leave the med lab.

"Question; you're the only one who can see him?" HR asks Barry. "Why? I mean...why?"

"They're both speedsters. Maybe it has something to do with that." Cisco guesses.

"My senses were at least able to pick him up. So that's something, but all I saw was a flash of white." Peter informs them.

"Maybe. But I think he's more than a speedster. I mean, when he had me, it wasn't like we were even moving; it was like we were instantly somewhere different, even from my perspective." Barry tells them.

"Did he say anything else?" HR asks.

"He said his name was Savitar." Barry answers.

"As in the Hindu god of motion?" Peter asks him.

"He said he was a god." Barry confirms.

"That's-that's nice. That's not scary...at all." Cisco says, not loving this.

They then leave to go check on Wally to see what's happening.

"Can you tell us anything?" Barry asks the two medical experts.

"Well...Wally's alive in there, but his vitals are really subdued." May says looking at their data.

"She's right, his brain function is seriously low. Something like you'd see in a coma patient." Caitlin tells them.

"I was in a coma when I got my powers. Maybe it's a similar process." Barry tells them.

"Is there a way of breaking this?" Peter asks Caitlin.

"When a caterpillar is in its chrysalis, it literally breaks its body down into enzyme soup before rebuilding as a butterfly." Caitlin explains to them, meaning if they do open it by force, they could kill him.

Joe starts rambling about how none of them know what's happening inside that thing and he can use his detective skills to possibly get something out of the Alchemy follower that they captured.

-

Suddenly, Peter's spider senses go off, but it's not a bad thing. It's like...there's something wrong, but not a bad wrong. It was like his senses were telling him that there's something about to happen.

But it seems more time has passed as he was staring off since Joe has returned.

"Wally!" Joe cried, rushing into the Cortex. Where he finds everyone all sitting around the cocoon lying on the bed. "What happened?"

"Uh...hey Joe," Cisco said awkwardly. "What do you mean?"

"Caitlin came by the precinct; she said that Wally was out. That he was okay." Joe explains.

May frowns, now noticing she hasn't seen Caitlin in a while. "I didn't even see her leave." She tells Joe.

Realization filled Barry at sickening speed. He got to his feet and ran.

-

When he got to the precinct his fears were confirmed. Julian Albert had been kidnapped, and a strange icy meta had gotten into an interrogation room.

"She took out the security camera so we couldn't ID her," officer Davis said, playing the feed for Barry. "I thought maybe you'd recognize her."

Barry swallowed. He did recognize her. "Uh, no. Why would she take Julian?"

"She's a meta," Davis snapped, preparing his gun. "They're all crazy. But, don't worry. We'll get her."

Barry shook his head slowly as leaned back over the cam, watching the feed on a loop. "What're you doing, Caitlin?"

-

"So they know she took Julian?" Joe asked after Barry debriefed the team on what had happened at the CCPD.

"No, they don't. They don't even know that it's Caitlin. Yet. So we need to find her before they do," Barry responded.

Peter now feels like a mess, like his whole world was starting to fall into pieces. This was worse then any sort of outcome he could have dreamed of after Caitlin had told him she had powers. She was out there, alone, scared, being hunted and they had no idea where.

"Now, what about this Savitar?" HR spoke up thoughtfully.

"Let's find Caitlin and then we can worry about Savitar." Peter snapped, cutting him off. He didn't care about some wannabe false-god when Caitlin is out there.

"You know guys, I-I agree with PP," HR said immediately. "Let's find Caitlin."

"Okay, you're right." Iris said. "When we find Caitlin, then what?"

Barry rubbed the back of his neck. He hadn't thought that far ahead. "I...I don't know- she's not thinking straight-"

"She's becoming Killer Frost." Cisco muttered. "It's just like in the vibe."

Peter's stomach tightened. "We don't know that yet." He states to his friend.

"Her mother said that the more she uses her powers, the faster she's gonna go. And saving Barry from Savitar... that must have put her over the edge." Cisco reminds him.

Guilt coiled in Barry's stomach. All of this was his fault.

"Alright, how do we find her?" Peter asked, trying to steer the conversation away from a subject that he was sure would be touchy for him.

"I don't know. I tried pinning her phone, and Julian's, but she must have ditched them both." Cisco says.

"Ahem!" HR cleared his throat importantly. "I'm a may..."

"Oh," Cisco snarked. "More suggestions from the genius over here."

"You don't call the genius, the genius calls you," HR responded immediately, and somewhat confusingly. "Question, how did you catch your Captain Cold? I've been reading about him in your files and he seems like a wily fellow-slow talker, but his MO is strikingly similar to our dear Caitlin's."

"What? No!" Cisco rolled his eyes, annoyed. "We tracked him using the satellites to scan for ultraviolet cold signatures..." He trailed off, and they could immediately tell that he had gotten something. "Oh. Okay."

He leaned over the computer, Iris standing up to peer over his shoulder at the screen. Barry walked around the desk to join them, almost buzzing with anticipation.

"No...nothing in the precinct..." Cisco muttered, peering at the computer.

"What's that?" Barry asked, nodding at a blip on the screen.

Cisco zoomed in.

"Transit food warehouse," Peter read, glancing over at Barry to gauge his reaction.

Cisco brought up a camera from inside the warehouse. "There she is. Okay, I'm gonna isolate the feed so no one else can see it."

"You guys figure out what she's making Julian do." Barry ordered, pulling away from the desk. "I'm going."

"I'm coming with you." Peter states grabbing his mask. "I got through Killer Frost, I know I can get through to Caitlin."

"Okay, let's do it." Barry agrees, knowing if there is anyone who can get through to Caitlin, it's him. He grabs onto Peter and speeds them off.

-

Caitlin and Julian were both hunched over a computer at the warehouse.

"I've found two individuals that searched for the name Savitar," Julian reported. Caitlin had frozen his arm less then an hour before when he had contacted the police. "Here are both their addresses," he continued. "Both of them are in Central City." He turned his gaze to her a little nervously. "What exactly are you going to do to them."

Caitlin was silent for a long moment, her strangely blue eyes looking unsure and almost like herself for the first time since she had kidnapped him. "I...don't know." She turned away, blinking a few times and shaking her head. "What am I doing...?" she whispered to herself.

The sound of typing made her turn. Julian glanced up from the computer, eyes opening with guilty fear. Before she thought, Caitlin sent an icicle at the computer, smashing the screen and sending it sliding off the table.

"What part of I'll freeze you to death did you not understand?!" she yelled angrily.

Julian backed into the corner as she held up her hands, swirling with frost.

She saw true fear in his eyes, and it brought her a great deal of satisfaction.

At that exact moment, a familiar flash of yellow lightning sped into the room. Caitlin's hands fell to her sides as Peter held up his own. "Stop."

Her eyes immediately faded to brown.

"Get out of here." Caitlin pleaded. She didn't want to have to hurt him. She didn't think that she could, but she needed to keep searching for Alchemy.

"You know I can't do that." Peter breathed, stepping forward towards the woman he loves.

"What're you doing?" Julian muttered behind him. "Take her out."

"You don't want to do this." Peter insisted, taking another step towards her and ignoring Julian. She turned away. "You don't want to hurt anybody."

"She's going to hurt someone! Knock her out!" Julian tells him.

In a sudden rash movement, Barry lit out with one of his fists and knocked Julian in the forehead. He crumpled back against the table, unconscious.

"Go on." Barry tells Peter.

"Caitlin." Peter pleaded.

She turned back to him, feeling tears burning behind her eyes and hating the feeling.

"Leave me alone." Caitlin warns him.

"What are you doing?" Peter asks her.

"I have to find Alchemy!" Caitlin exclaimed.

"We will find him," Peter told her firmly. "Together."

Caitlin tugged a hand through her hair. "No, you don't understand. I don't want to lock him up, I need him to helpme."

"Help you with what?" Barry now asks.

"I need him to get rid of my powers!" Caitlin tells them.

There. It was finally out of the bag. The real reason she was doing all of this, the reason she was panicking and the reason she had gone against every moral that she had ever had. She couldn't keep these powers. She couldn't be a danger to her friends.

Peter's eyes softened in sadness under his mask and he removes it to face her.

"I don't think it works that way." Peter breaks to her.

"You don't know that it doesn't." Caitlin said, eyes glittering with tears.

"I know that I love you." Peter tells her while taking her hand in his.

Caitlin's lips pressed together to hold in a sob as he took another step foreword, reaching for her.

"I will do everything I can to help you," he continued. "You and I...we...we've been through too much together to let each other down now. Please. Let me help you?"

Suddenly, something inside of her just snapped. Caitlin's eyes went electric blue. "Like you helped your uncle?" she said, voice icy cold.

Peter felt like something had been stabbed into his stomach. "Caitlin-"

"Or Ronnie? Or me?" Caitlin continued, the icy cold Killer Frost Fury inside of her unable to stop.

Peter swallowed hard. "I can help you, Cait." He said, trying to keep his voice steady.

"Oh, like you fixed everything when I got these powers?" Caitlin exploded. "My fear destroyed me. And you didn't even notice!"

Peter took a step back, hurt flashing across his face that even Barry was shocked to hear Caitlin say this.

The sudden sound of gun's cocking echoed across the room.

"Albert's down!" Davis yelled. "Shoot her!"

Caitlin turned toward the noise, raising her hands in icy defense, and just glimpsed the barrel of at least six guns pointed straight at her before she was moving.

Barry grabbed her around the waist and ran her out of harm's way, stopping them both behind a shipping container.

Peter quickly does some flips to avoid the bullets while placing his mask back on. "Hey, cool it, trigger happy group!" He tells the officers.

Furious, Caitlin glanced at her hand and watched a deadly sharp icicle form in her palm. Then she turned and slammed it into Barry's calf.

He cried out in pain, and the sound almost made her sick. Then the cold took over again and she glared at him. "That severed your tricep suri," she said. "Even with your healing abilities it'll take four hours to regenerate. Don't follow me." She warns him.

She hurled herself to her feet and ran.

Peter sees her running, and tries catching up with her when she uses her powers to create an ice wall so he can't follow.

Which means he needs to carry Barry back to Star labs...again.

-

Peter brings the two of them to Star labs where May checks on Barry's leg Caitlin stabbed.

"How much does it hurt?" May asked as she finished wrapping Barry's leg in gauze.

"As much as I deserve." Barry murmured in answer, pulling down his pant leg.

Joe walked into the room, putting his phone away in his pocket. "They took Julian to County General. He's still out cold. How hard did you hit him?"

Barry let out a breath. "I dunno... I didn't mean to knock him out." He reconsidered and shrugged a little, wincing as he tugged his shoe onto his bad leg. "Well...maybe I did."

Iris and Joe followed him back into the Cortex where Cisco was working.

"I hacked Julian's computer." Cisco reported, moving over to the desk. Peter walked over and stood behind him, rubbing her fingers over his shoulders. "Caitlin had him look up two addresses," he continued, hitting a few keys before his shoulder's relaxed under Iris' touch. "16 Hawthorn Avenue and 1104 Trimming Place."

"She's trying to find the acolytes," HR said from the corner, raising his drumstick.

"What would she want with Alchemy's followers?" Iris mused, looking down at the addresses and then back up at Barry.

"She must think that they can take her to Alchemy...she wants him to take her powers away." Peter says as his voice cracked a little.

Somehow, even with everything she was doing, Caitlin's motives were so innocent it amazed him.

"We know. We heard everything," Cisco glanced up at him. "What she said..."

There was nothing but silence for a minute when Cisco got back on subject.

"Well," Cisco said quickly. "Two acolytes, two addresses. Which one are we going to hit first?"

"We gotta watch both-" Barry started, turning away from the desk.

"You're gonna stay here," Peter said firmly. "You can barely walk. I'll take Hawthorn."

"I'll take Trimming!" HR called, hopping up from his chair and following Cisco towards the door.

Joe nodded. "I care about Caitlin, but I don't wanna leave Wally."

"Dad," Iris spoke up. "Barry and I will stay with Wally. You go with HR."

"Oh! Oh, yeah, I would love that. You and me: All star team up! You know, I'll make a couple cappuccinos for the road. So we're ready for tonight's adventures- hey." he stopped and turned toward Peter. "Not to worry, Peter. We'll help her!" He grinned and bobbed out of the door.

Peter let out a slow sigh, dipping his head foreword to hand between his arms.

Yesterday, everything was perfectly fine. And now everything is falling apart.

How had this gone so wrong, so fast?

-

Caitlin had just heard the prophecy about her future as Killer Frost when a yell cut the silence.

"CAITLIN!"

Peter.

Caitlin spun and headed for the door, glaring back one more time at the Alchemy acolyte. She ran outside and came to a stop in the dark road, raising her eyebrow at Spider-Man. "Really. You brought your toys?"

Peter was dressed in full Spider-Man gear, and had his feet planted.

"I'm hoping it won't come to that." Peter said seriously, staring at her.

Caitlin clenched her fists, preparing herself. "It won't."

"Look, I'm not leaving you out here," Peter continued. "I want to help you. You know that."

"There's only one person who can help me." Caitlin informs him.

"Really?" Peter shook his head. "You really think seeking medical advice from someone named Dr. Alchemy is the way to go? I'd prefer to get some from dr. Doom."

If it had been any other time, that might have made Caitlin laugh. Now she just smirked and shrugged. "Why not? My name is Killer Frost."

"Your name.." Peter cut her off. "Is Caitlin Snow." He corrects her.

The icy fury took hold again and Caitlin raised her frost-steaming hands. "Can Caitlin Snow do this?"

She sent five icicles toward Peter, one after the other, and he uses his reflexes to dodge every attack. Two of them hit the tree he dove behind, digging in deep into the wood.

"Caitlin, please!" Peter yelled, peeking a tiny bit around the tree. He was forced to duck back as a sixth icicle came shooting toward him, centimeters from his head.

When Peter pulled out next, he sent a web straight at her and Caitlin ducked. It just missed her.

A bolt of lightning zipped down the street and Caitlin gritted her teeth, sending a couple icicles at Barry. He flashed behind a car, then ran towards her, and Caitlin sent a stream of ice onto the road.

Barry slipped, landing on his back and sliding until he nearly hit her feet.

Caitlin stepped over to him, smirking. "How's the leg?"

Suddenly, Barry swept one arm across her ankles. Caitlin flipped foreword, the breath knocked out of her as she landed. She flopped back on her back, lying next to Barry and sending him a dirty look.

"I'm sorry, Caitlin." he breathed, glancing over at her.

"That was cold, Flash." Caitlin admitted. "But this is colder."

She swung herself over until she was laying on top of his chest and pressed her lips against his.

His face was slowly beginning to freeze, Caitlin sucking all of the heat out of his body and into her through their pressed lips.

Abruptly, Caitlin was slammed away from him by a vibe-blast. She flew off of his chest and slammed into the glass of a car, cracking it and then tumbling off the side.

Cisco appeared and ran over to where Barry was lying and crouched down by his blue-faced friend. "Start vibrating," he instructed. "It'll warm you up."

Soon, steam was rising off of Barry in plumes and he was groaning, rolling over. He was stiff all over, but the only thing he could think about was that this was it.

Peter runs over to Caitlin to make sure she's okay, but doesn't know what he's going to do now.

-

When Caitlin woke up, she was in a cell in the Pipeline. She blinked awake, staring out at numerous feet of Team Flash, and rolled to a sitting position.

"Oof!" Caitlin stood up, smiling charmingly out at her friends. "Guess I just needed a little sleep. Thanks guys. I'm feeling much better now."

Everyone stared stolidly back at her.

"It's okay," she said. "I promise I'm not gonna hurt anybody."

Silence.

"Hmm. Guess you're all smarter then I thought." Caitlin shrugged, walking closer to the glass. "Ya know, that was some blast there, vibe boy," she said to Cisco. "Kinda hurt."

Peter shook his head. "We didn't want to hurt you." He tells her.

She wrinkled her nose in disgust. "You're pathetic."

"Alchemy can't help you," Barry said. "But we can. I promise."

"Oh, like you promised Eddie?" Caitlin asked, shooting him a fake smile. She didn't miss the flicker fo pain that flitted across Barry's face. "And like you promised Ronnie? You know, for a hero, Flash, you sure let a lot of people around you die."

Through all of that sweet, forgiving, caring, beautiful exterior, it seemed that Caitlin really did blame them for all of the deaths that Team Flash had had to go through over the years.

"This isn't you talking." Barry muttered, almost more for himself then her. "It's the powers; they're messing with your mind. You're sick."

Caitlin shook her head. Her next words made him ache.

"I'm broken, Barry." Caitlin states to him and paused, smiling slightly. "But what do you care? 'Cause you've got Iris. You got your happy ending. Everyone else be damed. So I'll tell you what? Let me go, and I will leave you to your sad and miserable lives."

"No," Barry said firmly. "We're not abandoning you."

"You did this to me!" Caitlin yelled, lurching foreword toward the glass, eyes glowing white.

Barry shut the Pipeline door, leaving her in darkness.

-

Peter held himself together until he reached the speed lab. No one was around, and he let himself fall unto the treadmill and cry.

Too much had happened today. Too much had come to light, all at once. Savitar, Wally, Caitlin's true feelings. And he still was unable to get out of his mind that this was how she felt.

She had never truly felt like he was there for her. She had never really believed the words she had told him, about forgiveness and not taking the blame and how she would always love him no matter what.

He dropped his head into his hands, trying to stem the flow of tears before it all came rushing out in a torrent that he would never be able to stop.

The sound of footsteps made him look up. May came slowly down the stairs, smiling sadly when she saw him drop his head again and rub at his eyes.

"Hey," she said softly. "What're you doing down here?"

"Just...needed some time alone," Peter muttered into his hands. "To think for a bit."

"She doesn't mean what she said, you know that, right?" May said, sitting down beside him. "That isn't her down there in the pipeline."

"Yeah, that's what I keep trying to tell myself," Peter mumbled, rubbing his face. "Except that was her, May. Same face, same voice, same Caitlin. If she's._if she's feeling like that...how can I possibly call myself a good boyfriend if I'm not even there when she needs me?"

His voice broke and he buried his face in his arms, letting out a sob. May reached over and gently rubbed his back.

"I should have talked to her. I should have checked in on her. I should have noticed." Peter states, he's been by Caitlin's side ever since Ronnie's first death. How could he not have noticed something as big as this?

"You've gotta stop doing this to yourself." May pleaded, trying to get him to look at her. "You have to stop going through the what-ifs, Peter. We need you to be strong right now, just like I know you are. We need you. Caitlin needs you. And no matter how much you think you have, you have never let her down. Are you really going to start now, when she needs you the most?" She asks.

Peter nodded seeing what she means, and May pulled him in for a quick hug.

They were just getting to their feet when the lights flickered eerily.

"What fresh Hell is this?" They both think.

-

When they reached the Cortex, Barry barely had time to move everyone out of the way before Wally's cocoon exploded.

Joe had decided that he was going to take it upon himself to cut Wally out of his shell, no matter how many times Caitlin had said that it wasn't a good idea.

Now Barry rose up on his elbow and blinked spots out of his eyes, dreading what was about to happen.

Wally wasn't a pile of goo, but something definitely wasn't right. He was vibrating all over, like Barry did when he tried to phase, and he didn't seem to know quite where he was.

"Wally?" Joe whispered, pulling himself up from behind the table he had crashed behind.

Wally's head turned towards the noise. Iris stared at him, Cisco's hand resting on her arm as he made sure she was okay.

"Wally?" Barry echoed, moving foreword slightly.

Wally once again turned toward the noise, but in a second he had flashed out of the Cortex and was gone from view.

There was a long silence as everyone collected themselves. "Joe..." Peter trailed off, rubbing his hands over his neck and staring at the wreckage of Wally's cocoon.

"What did I do?" Joe muttered, staring at the floor in shock.

"Was this your idea?!" Barry cried, glaring at HR.

HR huffed. "No. Joe. I was helping Joe."

"No sign of Wally," Cisco reported, coming around the desk with his tablet. "I've got the satellite to scan the entire city for rapid movement."

"If he's a speedster he could be halfway across the country by now." Peter muttered, furious and stressed.

"How do we find him?" May asks.

Barry shook his head. "I'm more worried about what happens when we do find him," he admitted. "He didn't seem like he was all there."

"I shouldn't have cut him out of that thing," Joe said, self-hate evident in his voice.

"Joe, I-" Barry was saying but stopped himself. "What we need right now is a biochemist."

Joe stared hard at Peter. "You've gotta go talk to her, Peter."

Peter stilled, let out a long breath, and nodded.

Then he turned and headed for the Pipeline.

-

Caitlin stood up when Peter opened up the Pipeline door.

"We need your help," Peter said softly, staring at her with a look so gentle it rather surprised her.

Caitlin would have thought he would have been angry at her, or hurt, but instead he just looked...Sad.

"Caitlin," Peter said, and she snapped back to attention. "Wally, they blew him from the cocoon, but his biochemistry is all out of wack. He went AWOL."

"So?" Caitlin asks, not caring.

"So when we find him, he's gonna need your help." Peter elaborated. "He's going to need your medical expertise; your experience with metahumans. What we need is Caitlin Snow, MD."

Caitlin grinned and leaned against the wall. She looked mildly impressed. "So you came to talk some sense into me."

This was where Peter's plan came into place.

It was risky, but he trusted Caitlin more then he had ever trusted anyone else in his life before, excluding May.

She had never once betrayed him, never once done anything for herself. It was time for him to give her the opportunity that she needed to get herself back from this awful place.

"No," he said, walking over to the Pipeline controls. "I came to let you go."

The glass doors swung open and Caitlin walked cautiously out, tilting her head.

"For a smart guy...that was an awfully dumb move." Caitlin informs him.

Peter shook his head, staring down into her blue-tinted eyes.

"Like I said, you're free to go." Peter tells her

She squinted at him, not buying it.

"What's the catch?" Caitlin asks.

"You have to kill me." Peter informs her.

"You wanna fight, Spider-Man?" Caitlin asks while glaring at him.

This was exactly the reaction he had hope for. If Caitlin was truly gone, she wouldn't have even hesitated in slamming an icicle into his chest and stepping on his cold corpse on the way out the door.

"No." Peter said, keeping his face emotionless. "I'm not gonna fight you. But if you want to leave this room...you're going to have to kill me."

"Don't think I won't." Caitlin hissed at him

"Then do it." Peter said standing still.

Caitlin's eyes flashed white and she glanced down at her hand. A single, sharp icicle formed between her fingertips and she lifted it up, level to Peter's heart.

"What're you waiting for?" Peter challenged. He could see the struggle on her face, in the way she shifted her weight, in the tightening of her jaw. He was getting through to her.

"Come one, what's the big deal? Live up to your name, Killer Frost. I wanna see some killing. You want to be the villain? This is what they do, they kill their friends, because nothing matters to them anymore, right? Right?!"

He grabbed her wrist, pressing the point of the icicle against his own chest and making her jump. Caitlin's lips were pressed together, her face a mask of fury and something else... something a bit more human.

"Come on," Peter whispered, glaring at her. "Kill me, Caitlin."

Her lips started to wobble and he could see Caitlin returning.

Peter leaned a little closer. "You can't do it." He whispered. "You can't. Because underneath all that cold, you're still you. You're still the woman I love."

There was a long tense silence. Then Caitlin's lips parted and her eyes turned abruptly back to brown.

She gasped, icicle falling and shattering on the floor, and immediately burst into tears.

"Peter-"

Peter wrapped his arms around her, hugging her so tightly she thought she might feel a little bit of the warmth she thought she would never get back creeping back into her.

"It's okay." whispered into her hair, pressing his lips to her temple and rocking her back and forth. "I got you, Cait. It's okay." He assures her.

-

Peter and her walk back to the med labs where Caitlin does what she does best.

"I think extracting Wally early from that cocoon left him in a fugue state. His synapsis aren't used to functioning at super speed, so his mind and muscles are misfiring."

Her hair was back to being almost completely brown. She was currently in one of the medical rooms, explaining what had happened to Wally to the rest of the team.

"Will this stuff help?" Joe asked, gesturing at the small vial of serum Caitlin had just pulled from the machine.

"I've synthesized a neural compound that I think will get his mind and body running at the same speed."

"We just have to find him first." May said, glancing at them.

HR flipped his hat on to his head and spun to the detective. "Where to go, Joe? What's your gut tell you?"

Joe looked surprised to be asked his opinion. His brow furrowed for a moment, before he pointed at Barry. "The house that he grew up in. He used to go there when he missed his mother."

HR clapped triumphantly, and Barry sprung out of his chair to follow Joe. "Let's go."

He stopped at Caitlin and she handed him the vial. "Thank you." Barry tells her before leaving.

She nodded, and Joe and Barry flashed out to go neutralize Wally.

"It's good to see you're okay." May tells Caitlin.

"I'm happy to be back." Caitlin says.

When they got back, an unconscious Wally West in tow, Caitlin did a quick checkup on the new speedster before determining that he was go to go home.

That night, there was a sort of unspoken agreement between them as they reached Caitlin's apartment that Peter would be staying with her.

Caitlin trudged up the stairs ahead of Peter and unlocked her door, before taking off her coat and jewelry and wandering into her bedroom.

Peter followed her, hanging his coat on the hook and slipping off his shoes. He felt tense, and unsure of how the inevitable conversation between them of what had happened today was going to go.

He decided that he should speak first, and followed Caitlin into her bedroom before he said anything.

"I...I wanted to apologize." Peter started. He hated how stiff and fake his words sounded, but he wasn't quite sure what else to say without completely falling to pieces. "What happened today...you-you're right."

"No." Caitlin said angrily, turning around, eyes red-rimmed. "No, don't do that."

"What?" Peter questions, not understanding.

"Don't act like this was on you. What happened today...that was me. I was the one who didn't tell you about my powers. I was the one that hurt you. I am the one that you shouldn't even be wanting to look at, because I could have killed you today and you would still somehow love me!" Caitlin says as her voice breaks suddenly, and she gasped out a small sob before turning abruptly and ran into the bathroom, and Peter heard the door lock behind her.

Peter hurried after her, trying the handle even though he knew it wouldn't turn. He could hear the sound of her sobs through the door, the soft thump of her trembling back hitting the wall.

"Caitlin...let me in." Peter pleaded. "Please?"

"Go away," Caitlin sniffled. "I don't want to...I can't hurt you anymore."

"Caitlin, I swear, I will break the door." Peter threatened.

"I want to be alone." She tells him.

Peter sighed, and used his strength to break the door handle off (getting flashbacks for when he first got his powers) and then crouching beside her.

"No you don't." Peter said softly, placing his hand on her hair.

She was curled up on the tile floor, her face buried into her knees. He could see the glowing blue of her power-dampening cuffs through her shirt sleeves, and she shuddered slightly when he touched her.

"Come here." Peter whispered, tugged her into his arms and standing up, carrying her back to her bedroom.

He set her down on the mattress and crouched on the floor in front of her, forcing her to look at him. "If I say I forgive you, will you forgive me?"

"I don't deserve forgiveness." Caitlin mumbled to him.

"Cait, everyone makes mistakes," Peter said, taking her hands into his. "Everyone has rough days and rough times, and just because you are the most amazing, perfect woman I have ever met, it doesn't mean that that rule exceeds you, okay? Seeing you like this...see you go through this, as much as it kills me to see it also amazes me, because the fact that you could come back from all of this in time to help your team shows me how crazy strong you are. Stronger then I think any of us know. I've been where you are right now, and I'm gonna do whatever it takes to help you." He promises her as Caitlin blinked at him, teardrops balancing on her eyelashes.

"Even though you say it's not my fault, I should have been more noticed your needs and your struggles. I don't want this relationship just about making sure I'm okay. You've gone through just as much hardship as I have, and I never forget that. Everyone needs a break sometimes. But I promise you, Caitlin, you can be fixed."

Caitlin bit her lip hard and nodded, sucking in a shaky breath. The two quickly changed and crawled into bed and Peter wrapped himself around her, sighing into her hair.

"I love you." Peter whispered, kissing her forehead. "And I know I don't say it nearly enough, or maybe even at all, but Caitlin Snow: you amaze me."

"How do you do it? Always see the light in people?" Caitlin asks him as her voice still cracks.

"Because no one is ever truly gone. There is always light in the darkness. You just need the right person to shine it." Peter tells her, always happy to help.

"You're gonna fix my door, right?" She asks referring to the bathroom door he broke.

"I can fix it." Peter promises her. "There is nothing broken that can't be fixed." He tells her as she drifts off to sleep.

During the night, while the real Spider-Man slept, the Ultimate Spider-Man was making his first appearance.
