"From the beginning, I knew that Caitlin Snow becomes Killer Frost," she wrote, "and I can't wait to suit up and duke it out with the boys!" She didn't mention when she would make her Killer Frost debut, but did tell a Redditor to "Watch the season finale on Tuesday!" and "Soon!" when asked if the Killer Frost hype was real. She also disclosed that a Killer Frost costume has been created.
Additionally, she provided a few details about the upcoming season finale. "There is a wedding in the finale," she revealed. "Hopefully, it ends with 'happily ever after.'" When asked how it was to film that scene, however, she responded, "Fun. Emotional. Cold."
"The Flash" season finale airs on Tuesday, May 19 at 8 pm EST on The CW.
