Caitlin Snow also know as Killer Frost. She is one of Barry's best friends and partners. She had a relationship with Roney Romon "Fire Storm". He died trying to seal the black hole that Barry made. Caitlin fell into a dark hole because she thought that she would not get another love life until Jay. Jay is another speedster but from a different world. Caitlin and Jay fell in love and had a relationship for like 5 months until Zoom killed him. Cisco tried to cheer up Caitlin without telling her that in world two she was Killer Frost. Caitlin soon found out that she was Killer Frost in the other world but she told Cisco that she was not going to become her. In my opinion I think that Caitlin might become Killer Frost but not harm people. I don't thunk that she is going to turn into a bad person because she has a kind heart and she does not harm people.

Do you guys think that Caitlin might turn into killer Frost? We can also call her "Good Frost" or not that sound like a bad name think of one for me.
