Shout outs to all those who reviewed, you guys are seriously awesome; Raquel, Guest, deliriouz2468 and Lina

So first off I'm going to just answer some guest reviewer questions since I cannot do that through PMs;

Raquel: I'm surprised you felt a plethora of emotions that makes he feel happy that I can do something like that. Iris was put in a situation where she could go either way, she could break or freeze to death, best case scenario Iris has suffered some form of irreversible damage which may be expanded on. I'm going to try avoiding talking about Iris from the show since it seems to be a touchy subject for a lot of people. Personally I neither like her nor hate her I just do not care much for her character mainly because I found her to be a poorly written character.

Guest: Glad you enjoyed the fight I had a blast writing it. This originally wasn't going to be a Snowbarry story but as it progressed it has sort of delved into the pairing but I have a few surprises for everyone by the end.

Lina: Thanks for enjoying their fight, more like Caitlin kicking his ass. But As of right now there is something more but who knows how Barry and Caitlin will deal with their buried feelings, you will be surprised by the end. As for Iris, well as I said before I just give a crap about the show version, she's just boring, I actually like Laurel more than Iris and Felicity.

The Flash: The Fury of Killer Frost

Chapter 6: Frozen Fallout

Barry remained in front of the ice wall for a while, the world around him frozen in time. He looked down at his bleeding hands, something Caitlin would chide him for. He could feel the tears welling up in his eyes, his girlfriend was dying, because of one of his best friends, and now said friend, he may or may not have a crush on, was gone again before he could bring her home.

He tore his eyes away from the ice wall back to the now dead, or near dead Iris. he had to save Iris, if he couldn't save Caitlin in this moment he needed to use this time to save the woman he loves. Barry grabbed the ice sculpture of his girlfriend and flashed Iris to S.T.A.R. Labs as fast as he could. He was praying to every god in the sky that he could think of that Cisco, Harry, Jay and Professor Stein were already there, he was also praying that Caitlin wasn't lying when she said Iris was still alive. Upon entering the Cortex in a blur surrounded by golden electricity Barry slid to his knees and everyone present turned to Barry.

"Barry what's…Oh, my god." Jay said as he saw the ice sculpture of Iris in Barry's arms.

"Please…" Barry said. His voice was quivering and tears were dripping down his cheeks, evidence of his sorrow and worry. "Please help…"

"What happened?" Cisco asked as he rushed to his best friend's side.

"It…it was Caitlin…"

"No way…" Cisco fought the new information. "I don't believe it! I won't believe it!" He turned to Barry completely panicked "Please tell me Caitlin didn't go all Killer Frost!"

"It happened Cisco!" Barry exploded at his surrogate brother. "SHE ATTACKED US AND LEFT IRIS FOR DEAD! I DON'T WANT TO BELIEVE IT CISCO BUT I SAW IT WITH MY OWN EYES!" Barry began to breathe heavily, "It was like she was a completely different person. Someone I didn't recognize." He was mad at Caitlin, no he wasn't mad with her, he was angrier with himself for not being able to save her. A reassuring hand made its way to his shoulder. Barry looked up to see Jay giving him a reassuring smile.

"Barry," The older flash reassured his younger alternate. "Now's not the time to dwell on that. We have to do our best to save Ms. West."

"Cisco, quickly prep the medical bay." Dr. Wells ordered as he and Jay took Iris from Barry. "We need to thaw out Ms. West immediately."

"I've never dealt with a completely frozen person before." Cisco said. "How are we supposed to thaw someone completely encased in ice?"

"Now's not the time for that Cisco! We need to somehow thaw her out." Professor Stein interjected. "Is there a large bath somewhere in this lab?"

"I'm sure one of our prototype healing tubes will suffice." Harry added. "We can just leave it open and place Ms. West in it. Garrick would you-" Dr. Wells never finished as the older flash disappeared and then reappeared pushing a seven foot cylinder made of glass and metal.

"Is this it?" The old speedster asked

"Yes it is." Dr. Wells removed his glasses. "And we'll need quite a bit of warm water."

"I'll set up the hoses and reroute the water from the boiler. It should allow it to cool off before it gets to her.

"Wouldn't hot water work faster?" Barry asked, his voice did not confine his fear for Iris' life.

"If we were to use a higher temperature right away there is a high chance that it'll just case her to crack and shatter. Even if that doesn't happen it'll just send her into Shock." The nuclear physicist cautioned. "Have you never read of Hannibal's Campaign through the Alps Mr. Allen?"

"I uh, um…no, I've never been a history buff."

"Dude comes across large rocks blocking his path so he has the men heat them up as hot as they can and then cool them down immediately with water causing them to crack from the extreme temperature shift." Cisco summed up the main point. "Basically the opposite would happen here. Like Stein said, if we heat her up too quickly we'll do far more damage."

"If we're done with idle chit chat we have to save Ms. West." Wells interjected.

Caitlin was violently slammed into the ground. She tried to brace herself but in putting all her weight on her wrist broke it. Wincing in pain she clutched her wrist, and almost immediately she used her ice to form a makeshift brace around it. There was a rush of air and a flash of crimson red electricity and before her stood the Evil Barry as she had grown accustom to calling him.

"Damn it Dr. Snow!" He was still furious. In another moment he pinned her against the wall. One arm held her arms above her head while his right arm pinned her throat. "You were supposed to kill the Flash!"

Caitlin struggled and when she had enough room she bit into his arm hard enough to draw blood from the evil time-traveling speedster with her crush's face.

"AGH!" The reverse Flash released Caitlin and clutched his right arm, looking closer Caitlin noticed a layer of ice had formed over it. "Damn bitch!" He grabbed Caitlin and smashed her hear into the wall. Caitlin felt liquid trickle down her neck and paint the wall red.

She felt her consciousness fading so she reached out and grabbed Eo-Barry's collar, digging her nails into his skin, and began to drain heat.

The Reverse-Flash felt like his skin was on fire as Dr. Snow attempted to drain his heat. "Trying to kill me Dr. Snow?" He took her hand with his own free one and peeled it off causing Caitlin a great deal of pain.

"I won't let you hurt Barry, even if it kills me!" She mumbled from under his hand.

"Oh so you don't remember the fact you killed Ms. West?" Caitlin's eyes widened. She didn't kill Iris did she? Maybe she did, but she told Barry she left her alive, just frozen. But if the Reverse-Flash thought Iris was dead then maybe she could use this to her advantage.

"No…I…I didn't…I didn't kill her…" Caitlin forced tears well up in her eyes. Once again she had hurt someone, and what's worse she might have killed Iris, a woman she had grown accustom to seeing as a sister figure. She only remembered bits and pieces from earlier, most of it was fuzzy, Barry trying to approach her, kissing someone, creating the ice wall to separate herself from Barry, but for the most part it was like she was watching someone else drive her body like a car.

"You remember don't you?" The evil speedster asked. "All the horrible things you did, all the ways you hurt Barry Allen today. Face it Dr. Snow, you're a monster now, you're Killer Frost." Caitlin broke down. Her frozen tears fell down her cheeks. It was too late for her, she was now a monster. "That's what I'm counting on!" He pulled her back and slammed her head into the wall again knocking her out.

Barry watched from the other side of the glass as Iris was lowered into the makeshift tub of warm water and they turned a makeshift shower on above her. As the warm water cascaded over her frozen body Barry watched with fleeting glances as the frost began to melt.

'How could Caitlin do this?' Barry asked himself 'How could sweet innocent Dr. Caitlin Snow-Raymond do this to him and Iris?' The same question kept asking itself in his head over and over and he pondered on different answers. 'She could have killed me and Iris but she didn't it's almost like she didn't want to kill us…but if she didn't, why did she attack us?' This day had started off pretty good and then in a matter of minutes it all went straight to hell.

Barry was snapped out of his thoughts when his phone vibrated. Taking it out he noticed three missed calls from Joe. Guilt suddenly swelled up within Barry and the fastest man alive called his foster father.

"Come on Joe pick up." Barry started pacing as he waited for the conversation to start.

"Barry what's going on? There was some kind of meta-human attack. Reports are coming in saying it was someone with ice abilities, was it Caitlin? I've been trying to call you and Iris but she won't answer her phone." Joe was talking at a mile a minute trying to gather as much information regarding the attack

"I know Joe…I know about the meta-human attack." Barry whimpered out. "It was Caitlin..." Joe picked up on his son's distraught tone.

"Son, what's wrong."

"I was there Joe, We…" He swallowed hard. "We were there." Joe was silent.

"Where are you? Are you two OK?"

"I'm fine, but Iris…"

"What happened, Barry? What happened to my baby girl?" Joe demanded. His tone shifted to one more serious and angry.

"She…she was frozen Joe…Caitlin froze Iris." There was only silence on Joe's end for a solid minute before he could find the courage to speak. "Joe? Joe? Are you still there?"

"Where are you now? The Hospital?"

"No, no, we're at STAR Labs now. Cisco and Harry are trying to save her as we speak." Barry turned back to the window to see that some of Iris' skin was poking through the ice.

"I'll be there in ten minutes." Joe said and somehow Barry didn't doubt him.

True to his words Joe arrived ten minutes later and immediately ran into the medical lab to his half frozen daughter.

"IRIS!" he yelled as Jay and Professor Stein grabbed him.

"I'm sorry Joe, you can't be in here!" Jay said "Not until we know she's been completely thawed out and fine!"

"What do you mean?" Joe demanded as he grabbed Barry's mentor by the collar of his jacket "WHAT THE HELL DO YOU MEAN BY THAT?"

"Technically she's dead Detective, her heart's not beating!" Harry shot at the old cop which made him release Jay and slide to the floor.

"She's dead? My baby girl's dead?" Joe's eyes were filling up with tears. First he lost his wife, and now he lost his daughter.

"She isn't completely dead yet." Stein gently told Joe. "We're-"

"DO SOMETHING DAMN IT!" Joe was emotionally destroyed at this moment and no one could say they didn't feel sorry for him. Joe cried into his hands. "SAVE MY LITTLE GIRL DAMN IT!"

"We're doing the best we can Joe!" Jay yelled back.

"THEN DO BETTER!"

"You need to leave now Detective West." Stein insisted. "You aren't helping the situation."

"Please! Let me stay! She's my baby girl!" A pair of arms wrapped around his own and began to pull him back out of the room. "NO! NO! LET ME BE WITH MY DAUGHTER!"

"I'm sorry Joe," Barry's voice said in his ear. "Neither of us should be here now."

"NO! LET ME STAY WITH HER! LET ME STAY WITH HER!"

"But there isn't anything you or I can do now." Joe continued to cry out as Barry dragged him out of the room.

They sat down and did the only thing they could, wait. And after waiting for what felt like an eternity. Cisco came out to tell them some news.

"Her hearts beating again." Cisco said and instantly a weight that Joe and Barry didn't know was on their shoulders was suddenly lifted.

Joe brought his head into his hands and started to cry tears of joy while Barry exhaled heavily.

"Can we see her?"

"Well, yeah but she's still unconscious and we still don't know how much damage has been done internally." Cisco answered. He saw the looks that they shared. "Go on and see her" He moved out of the way so the most important men in Iris' life could be with her.

Barry and Joe each stood on one side of the now thawed out Iris West. She was still unconscious but that didn't stop Joe and Barry from expressing their love.

Joe rubbed her hand gently as tears threatened to fall. "I swear baby girl, I'm gonna make Caitlin pay for what she did to you."

"Joe…" Barry began to say. He could almost see the rage threatening to explode from his adopted father. "You can't blame Caitlin for this."

Trying to remain composed Joe stood up and subconsciously walked over to Caitlin's old desk and in an uncharacteristic fit of rage he swiped everything off it. The computer, the microscope and even two pictures flew onto the floor and shattered when they made contact.

"JOE!" Barry yelled at his foster father but the old detective didn't seem to hear his son as he stormed out of the room. "I'll be back, Iris." Barry said before kissing her forehead and racing after Joe.

"Joe! Hey Joe! Where are you going? Joe! Stop!" Barry kept calling after Joe but it was like he was deaf or ignoring Barry until the Flash grabbed him by the shoulder and turned him around so they were face to face. "Joe where are you going?"

"I'm going after Caitlin." Joe's tone was unimaginably serious. "I'm getting the Meta-human task force together and we're going to bring that woman to justice!"

"Wait, what? Joe you can't be serious!"

"Do I look like I'm kidding Barry?" Joe asked to which Barry shook his head. "That woman has killed Barry, she isn't even human anymore. She killed Ronnie, almost killed those two cops, you and Iris."

"Joe just listen to me she wasn't even in control!"

"Of course she wasn't in control Barry!" Joe fired back. "She hasn't been in control since the moment she woke from that damn coma!" Joe took a deep breath before continuing "You had better hope that you find Caitlin before I do Barry." Joe said to his son. "If I find her first I don't think I'll be able to stop myself from putting a bullet in her head."

Barry was taken aback; this was a side of Joe he had never seen before, the vengeful parent. "Joe you can't possibly mean that."

"The problem is Barry, I think I absolutely do."

When Caitlin woke up she found herself once again strapped to the cold metal table. She tried to look around but even her head was restrained.

"Don't bother trying to escape Dr. Snow. That metal is an alloy of Titanium, Vanadium and Promethium, basically it's indestructible, even if you super chill it."

"You're sick!" She spat out.

"Why thank you." He took it as a compliment. "It appears that our initial test run was a partial success, though" He turned away from Caitlin to grab a syringe. "I think we gave you too much freedom, a mistake we won't be making a second time."

"Please…" Caitlin pleaded "Please don't…"

Eobard gave her a strange look. "Oh, you think this is for you? Ha!" He laughed. "This is for me. What I have planned is, well let's just say you'll be a bit more emotional this time." Caitlin watched as Grodd once again entered the room pushing a man Caitlin recognized. "Dr. Snow, I believe you've met Mr. Bivolo."

"Get your paws off me you damn dirty ape!" Bivolo yelled at the gorilla

"How original…" Grodd spoke.

"You've made a huge mistake." Rainbow Raider threatened "I'll have you tearing each other apart before ARGH!" He screamed in pain as Grodd assaulted his mind.

"Less talk!" Bivolo looked like he was about to whammy Eobard or Grodd but the large ape grabbed his mind making Rainbow Raider's body stand at attention like a soldier.

"Well done Grodd, now begin." Caitlin watched as Bivolo marched over to her like a zombie soldier. She knew what was coming, they were going to make her a rage monster with ice powers, that was something she couldn't let happen because she would most likely kill everyone.

"Funny thing about the color red, it is universally synergistic with rage and hate. I should know, I've met people who wield red light as a weapon. And they are some of the most vengeful bastards I've ever met." Caitlin tried to shut her eyes to prevent eye contact with Bivolo but the Reverse-Flash flashed over to her and held her eyes wide open. "Oh don't do that Dr. Snow. That'll spoil all the fun we're about to have." Caitlin wanted to cry but found she couldn't as her eyes flashed red, her heart rate and blood pressure increased, she felt rage boiling up inside her like a bubbling cauldron. "She's getting mad Grodd, now's the time to suppress that rage. We don't want her attacking us now."

"Yes Father." The massive ape tossed Bivolo aside and focused on Caitlin, mentally bombarding her with metal barriers to aid her inhibitions to hold her rage back.

Caitlin screamed in pain as the ape assaulted her mind. She wrestled against the restrains and ice formed around them and spread over the table.

"Now, let's use one last color of the spectrum." Thawne said with sinister glee. Taking Control of Bivolo one more time Grodd used his abilities to amplify the emotions raging through Caitlin, but not with red rage. Instead they used violet.

"Well done Grodd. Hell hath no fury like a woman's scorn." Eobard commented as a wicked smile spread across his face. "It's time to unleash our angry doctor. And I have a wonderful idea on where to do it."

Back at STAR Labs, Barry sat alone in the treadmill room things just weren't going his way right now. He wanted to believe Caitlin was good and always will be but part of him was beginning to doubt, maybe he as just imagining it when Caitlin's demeanor changed. Even though she almost killed Iris and now she has the entire CCPD gunning for her head Barry can only sit there and hope everything will go back to normal, or at least their version of normal.

"Hey man, you ok?" Barry turned to see Cisco enter the room carrying a tablet close to his chest.

"I don't know Cisco." Cisco sat down to his friend.

"You're thinking about Caitlin aren't you?" Barry turned to the engineer, his face told Cisco everything. "Look dude, Caitlin's my best friend. I've known her longer than anyone, aside from Ronnie, but that's beside the point," Cisco was trying to lighten the mood but sometimes his jokes don't work. "You said she acted differently when she froze Iris right?"

"Yeah, but now I'm thinking I was just-"

"I believe you."

"What?"

"Like I said, I've known Caitlin the longest and I know she would never willingly hurt someone, physically or emotionally." This was true of Caitlin. For the time that he's known her she had never once tried to harm anyone. If she did hurt him, when she reset his bones, it wasn't intentional, hell when she killed Ronnie it wasn't intentional either, so why would she intentionally try and kill Iris?

"So you think Caitlin's not Caitlin?" The speedster asked.

"Exactly" Cisco showed him his tablet. "Here's the security footage from earlier." They both watched the fight between Barry and Caitlin. "Notice anything?"

"Not really." Barry said "Aside from her kind of kicking my ass."

"Watch it again." They watched it again. "Did you see it?"

"I give up Cisco what am I supposed to be looking at?"

"Watch Iris." Barry watched the fight unfold once again and this time he noticed something he hadn't seen before. The moment Caitlin clutched her head Iris stood still.

"It's almost like"

"Something's hijacking their brains." Cisco finished. "Now watch the rest of the footage." Cisco fast-forwarded it to the end of the fight, just after Caitlin formed the Ice wall before pausing it. "Right there" Cisco pointed as a large black shape on the side of one of the buildings.

"Grodd." Barry recognized the shape immediately. "You think he's behind this whole thing?"

"Partially." Cisco said "I don't think he's working alone mainly because of this" he froze the frame again and zoomed in on the ice wall. "Watch closely as I play it frame by frame."

Even through the ice Barry could make out her shape behind the ice. Cisco played it frame by frame the image shrunk indicating that Caitlin had slid down but two frames later she was gone 'Wait! Go back two frames!" Cisco pressed a button and stopped the footage and went back two frames. The small shape, which Barry assumed was Caitlin, had slid down the wall and in the next frame there was another figure and the next frame they were gone. "What was that?" Barry asked as he pondered the still image.

Cisco zoomed in on the two black spots behind the ice wall. "I don't know. But it moved far too quick to be human."

"You think Zoom's back?" Barry asked, Jay had warned them about Zoom, but he had been dealt with and the Reverse-Flash was in his original time. "Or the Reverse-Flash?"

Cisco shrugged he was lost as Barry was. "I really couldn't tell you. But at the speed he's moving it is most definitely a speedster."

"Whatever it is it's our only lead to bring Caitlin home."

"I'll head there with Professor Stein and Dr. Wells" Cisco closed the footage. "We'll see if we can find anything from either Grodd or the other one."

"Alright let's do it Cisco, let's save Caitlin."
