Barry's confusion made him loosen his grip because in a split second she broke free and widened the distance between them without ever taking her eyes off the speedster. Then she circled him slowly like a cat circling her prey just before the kill. "You think you're so clever, don't you Flash? That I'm just this poor hurt girl that's all upset because someone broke her heart.." Barry closely followed every move she made but made no attempts to catch her again. Partly because there was something about her that he found more than a little intriguing. "I'll admit that I did not see that coming, Ronnie choosing that wallflower over me but that's his loss. Not mine. But what does bother me is that he used me. He used me to get back to this Earth the same way you used me to get into Zoom's lair. And the same way Zoom used me to do his bidding." Her voice grew louder with each passing word and Barry braced himself for the wrath she was about to unleash. He didn't have to wait long. Dodging the spikes of ice she aimed at him. "And. I. hate. Being. Used!"
Barry made it to the other end of the room and then stopped. Killer Frost's back was turned so he knew he only had a moment before she would fire again but he had to try and calm her down.
"I didn't use you" he replied but spikes were already flying through the air again so she wasn't listening. He moved a couple of feet out off the line of fire and tried again. "I never wanted to leave you behind but there was no time. Stop, I don't want to hurt you." The only reply she gave was sly smirk and then muttered "trust me, you won't." Suddenly Barry remembered her saying the exact same thing back on Earth 2 and he was starting to see things from her perspective. Yes, Zoom did manipulate her by holding Ronnie hostage and Deathstorm only used her to get closer to Zoom but after everything was said and done, the one that suffered the most was Killer Frost. And that was something he could relate to.
To end the fight he started running in a circle around her, faster and faster until the lightning was a blinding and continuing streak. At first it seemed to be working. Killer Frost stopped creating spikes but now an ice storm was building within the circle itself. Lightning and Ice collided but much to Barry's surprise it seemed as if the energy was absorbed by storm. His bolts of lightning fizzled out faster as he could throw them and above the thunder of the storm he could hear her triumphant laughter. Cisco was yelling in his earpiece. "Barry! Talk to me, what's happening. Your vitals are all over the place, man. BARRY!" Confused by what was happening before his eyes Barry stumbled back. As the storm disappeared a figure emerged from the ice mist that was surrounding her. It was still Killer Frost but her appearance had changed dramatically. Her skin wasn't pale like before and her hair was no long white, it was blonde. The one thing that was still the same were her intensely blue eyes that now gazed at a stunned Barry. She sighed satisfied and placed her hands on her hips. "Now I really needed that."
"How..how is that possible?" Barry mumbled as he still didn't believe what he was seeing. Killer Frost looked like a regular girl again. And a very attractive one too.
"The simple answer to that question is energy. Energy creates heat and if I absorb enough of it I turn back to this. Luckily for me the effects aren't lasting." She turned around and walked a few steps away from him.
"Come back with me to S.T.A.R. labs. We can run a few tests and maybe we can find a more permanent solution for your condition." As soon as Barry found his words again he stepped closer to her, convinced that she would welcome the chance to be healed but he couldn't be more wrong. Just as he reached out to take her arm she turned. At first he only saw the grin on her face but by the time he felt the cold it was too late. A long ice spike penetrated his side just below the ribcage. Shocked by her action he stumbled a few steps back until his back hit the stone cold wall. "What the..but you're human now!"
She flashed him a seductive smile and crossed over to him. "Relax, you're not going to die. I didn't hit any vital parts." While she spoke she traced the symbol on his suit with her index finger but then locked her eyes with his again. "I don't need fixing. I am perfect the way I am and I like being Killer Frost. You're not going to use me as your science project but it's nice to know that your powers can be so satisfying." Her mouth was now hovering closely to his that he completely forgot about the blood that was now staining his suit. She taunted him by pressing her body against his but just as it started to feel pleasurable she put her palm against the wound and pressed. Pain shot through his body but as he flinched she pressed her lips on his, catching his lower lip between her teeth and gently tugging on it. The unexpected warmth surprised him. Killer Frost was messing with his mind in ways he couldn't even begin to understand. The ice inside his body was starting to melt and blood trickled out of the wound but the cold also made the area numb. Any smart person would run to the nearest doctor but Barry had other things on his mind. Eagerly he started to kiss her back, his hands shifting to her hips. The little voice in the back of his mind was still telling him that this was the same woman that was trying to kill him but the way she moved against him was intoxicating. And the way she kissed him, he was convinced she felt the same way. Until she pulled away.
Even if she tried to hide it he noticed that she was breathing heavier but what was even more noticeable was that she was changing back. There were white streaks running through her golden hair and her skin was looking much paler. He could practically feel the walls going back up.
"Cait, please let me help you. We can figure this out."
"There is no we, Barry. I don't play well with others and I know what I have to do."
Barry flinched when he tried to move. The numbness was wearing off and every move he made felt like getting stabbed all over again.
"What does that mean, you know what you have to do?" She just stared without answering so he filled in the blanks himself. "You're going after Zoom? No, you can't. You're going to get yourself killed."
Killer Frost chuckled softly. "Here you go underestimating me again. I'm sure Zoom and I can come to some sort of arrangement so he'll let me go back to my Earth. I only have to give him something he really wants. From now on no one will ever use me again. It's time I get what I want."
He couldn't believe what he was hearing. After everything she still wanted to go back to Earth 2? Somehow it never occurred to him that she would ever go back and if he was honest with himself, he didn't want her to leave.
Without giving him a second glance she stormed out, leaving him bleeding against the wall. "Barry? Barry, it's Caitlin..answer me!" He pressed the earpiece in his suit and coughed. "Yeah, I'm okay. I'll be right there."
