When the Cosmic being arrived, not knowing what it was, Doctor Caitlin Snow had shifted into super-powered alter ego known as Killer Frost. Now she was in control as the being spoke explaining the challenge, the various rules and limits to it. She responded to the being, "So as long as I don't stop or reverse time I can do anything I want. But nothing will be permanent unless I can get people to agree with me. I have twenty-four hours to do all this. Interesting."

"Correct. Do you accept?"

Caitlin in the back of her mind wanted to reject it, but Frost was different, "Sure. When do we start?"

"Now." As the being responded and vanished, Frost could see the clock of her mind counting down. Using it's power to speed up her perception so she could plan things out.

Caitlin thought to her, 'We shouldn't have made that deal. Messing with people using that power is wrong."

"Even if you could help Barry with his new enemy? Help with the various metahumans including the ones from the bus?" Frost thought, pointing out the metahumans which were created when they freed Barry from the Speedforce.

"I doubt that you were thinking of helping other people." was the reply, since they knew each other very well.

"Well, have some things I would like to get while this is going one. Things you want too, even if you don't want to admit it. Poor, poor Caitlin. Always looking after everyone else. Forcing all selfish thoughts and desires to the back of her mind, with her anger and other negative feelings. But do you think you could stop me? Would you want to stop me?

If you want, we can use this power to go our separate ways and do what we want or think is right with the power? Or do you want to watch me use this power?"
