The Flash star, Danielle Panabaker, who plays Caitlin Snow, confirmed recently in a Reddit AMA that her character will eventually become Killer Frost on the show, and quite possibly we could see that transformation as early as next season.
“From the beginning, I knew that Caitlin Snow becomes Killer Frost. And I can’t wait to suit up and duke it out with the boys!” Panabaker said. She also added to be sure to watch the season finale for futher developments, which may hint at Killer Frost. Panabaker even confirmed a Killer Frost costume has been designed by the production team of The Flash.
Even if Panabaker’s character gets ice powers at the end of the season, she did not specify whether her character would turn evil right away. However, fans can look forward to a wedding in the season finale that Panabaker describes as, “Fun. Cold. Emotional.”
The Flash season finale airs on May 19th on the CW network at 8:00pm EST.
