Unfortunately, Killer Frost (Danielle Panabaker) is also after Tracy so Team Flash must battle their old friend, which proves to be particularly difficult for Cisco (Carlos Valdes). Joe (Jesse L. Martin) and Cecile’s (guest star Danielle Nicolet) relationship takes a big turn.
Flash will learn that Caitlin aka Killer Forst is now working with Savitar. Grant Gustin, who plays Barry, told TV Line, “Barry is devastated to find out that Killer Frost helped Savitar. And now he’s back, and it’s happening for real. It looks like she’s helping Savitar, so this is another step in the future actually coming true.” The first step for Team Flash, therefore, “is making sure there’s no team-up here and they get their friend back.
Teasing an intense scene between Cisco and Julian, Valdes told the outlet, “Today I’m doing a scene with the beautiful Tom Felton, who makes it very difficult for me to stay focused on the scene because of how gorgeous he is….They reach a bit of a rift, because Cisco carries these reservations with him as of late about his powers. This is his worst nightmare, because the last thing he wants to do is hurt Caitlin.”
