When Barry looks back on his life, this day will undoubtedly be present within his combination of nightmarishly bad moments. Without his speed, he was back to the old Barry, in his forensics lab, chasing up cold leads. So when he got a call from Cisco saying that they needed him at STAR Labs, he began to run to the door...and then was reminded of his complete and utter lack of awesome powers. He remembers when he lost his powers the first time, and tries to connect the two together, attempting to discover if there were any similarities. Maybe he could try to get Wells to put together the same lightning strike, maybe it would jolt his powers back to him. Except he didn't believe that was possible. The only one who believed in him then was Caitlin. And without her, he didn't know if he could believe in himself again. Zoom has punished him over and over again, broken his back, destroyed his heart and hurt his soul. He didn't even know if it was possible to beat him in hand to hand combat. Through all of those thoughts and fears, Barry hadn't even realised that he was standing in front of STAR Labs. The place where all of this begun. Usually, he ran in with a smile gracing his face, being able to see all of the most important people in his life in one place, all committed to helping him. Today, however it wouldn't seem fitting for that. So he walked, hands in pockets, a cloud over his figure, lips clenched into a harsh frown. His footsteps alerted Harry to his presence and he sighed as he saw the man alone.

"I'm guessing things didn't go as planned with Jessie?" Barry asked, words completely neutral, eyes glassed over.

"No. They did not. But that isn't why I asked Ramon to call you," Harry said, deflecting the man's question easily as he placed the syringe he was playing with down onto the bench with a soft clang. Barry motioned for Harry to continue.

"I know how to give you your speed back" Barry's eyes widened and his face showed the first sign of real emotion all day.

"Ho..what? How?" Barry was at a loss for words. He figured Harry might eventually come up with an idea or two of how to get his speed back, but he didn't expect the man to discover one this soon.

"By recreating the accident that gave you your powers in the first place." Harry spoke as if it were a necessity, not simply a choice or just an idea of what they could do to harvest Barry's powers back to his body.

"But the only way to do that would be to..."

"Recreate the particle accelerator explosion. Yes. I know." Barry's face was now one of shock and disscontempt.

"You can't. You know how many people it affected last time." The fear was obvious in the tone of the forensic scientist. He wanted to save Caitlin, but not at the cost of having to deal with another set of new metahumans.

"I know, that's why I'm going to contain it." Harry looked into Barry's emeralds, seeing the struggle within. "You can't get your Caitlin back without your powers. Just think about it." And with that, Harry walked out of the room leaving a very shaken Barry with something to obviously consider. He knew Zoom would come back to wipe them out. And when he did, he needed to fight. The whole world needed him to fight.

Caitlin had been in constant fear ever since she had begun to help her metahuman double. She couldn't live with watching her die, and if Zoom was to show up earlier than expected, she would be. Frost noticed her glance and raised her eyebrows as her sapphire eyes widened.

"Awww Caity, are you worried about me?" The tone was still playful, even as she knew that death was right in front of her. Even if she got out of here, it was likely Zoom would still kill her at some point in the near future. But if she could have some role, however small, in his downfall and then be reunited with Deathstorm, it would be worth it.

"I don't want you to die. I couldn't live with myself if I had a chance to save you and didn't." Caitlin walked back over to the steam engine as she spoke, moving with pace, knowing that the time to hypothesise was over. She needed an answer. "You might want to take a step back" Frost snickered and did as she was told by the scientist, taking a couple of steps away from the front of her cell.

"Let's see this little magic trick of yours."

Caitlin bit into her lower lip softly and nodded, before pushing the lever down. Almost instantaneously, bright sparks of light came from around Killer Frost's cell, the blonde's eyes stunned, not surprised that Caitlin's theory worked, but surprised that her freedom was only one ice attack away. Caitlin's face lit up as she saw the light, her angelic teeth framed by pale pink lips. But that expression disappeared in an instant as blue lightning entered Killer Frost's cell, materialising in the demonic figure of Zoom.

"NO!" Caitlin screamed as he lifted the blonde up by her throat, her icy blue eyes bulging out of her head before a needle was jammed into Frost's arm. Not the fatal shot either of the Caitlins were expecting, the speed demon pulling blood from the woman's body. Frost's mouth was open, a little squeak of pain elicited from her plum lips as he drew more...and more. Eventually, the syringe was full and he threw Frost's body against the wall of the cell, the woman alive, but barely moving, a heaving chest characterising her figure. In an instant however, Caitlin couldn't see her anymore and she was back on the bed, chained up. The only problem was, this time, there was a stand of medical equipment next to her. Zoom had removed his mask to stare into the woman's eyes.

"What have you done to Killer Frost?!"

"Nothing...yet. If this works though, she'll be dead by the time you wake up though."

"No...please...don't hurt her."

"Why? Because you have grown attached to her?" Zoom couldn't help but chuckle through his words. "She's a traitor. And the price for treachery is death!"

"If you truly love me, you'll let her live." Caitlin begged aimlessly as she tried to trip him up through guilt and affection once again. As they were having their discussion, Zoom was moving Frost's blood from the needle to the bag at the top of the medical stand.

"Don't worry. I'm not going to kill her...yet. I still need her for something anyway." That was when Caitlin realised what the madman was about to do. The look of realisation in Caitlin's chocolate eyes only made Zoom's smile grow as he attached the needle into Caitlin's arm, a slight grimace crossing the woman's face as the blood began to run slowly into her arm.

"My ice queen will soon be born." Zoom said, moving to brush a strand of auburn hair off of her cheek, before injecting her with a sedative, sending her to a slow sleep. He would much prefer a professional to conduct the transfer, but he had been studying blood transfusions for months. He knew this would work. It had to.
