Actress Danielle Panabaker, who plays who plays Caitlin Snow on the series, joined Russ Burlingame of Comic Book.com to talk about this week's game-changing episode, her feelings about Killer Frost and what she's heard about the upcoming Arrow/The Flash spinoff series. Danielle said, "I'm really grateful to our writers that they've given me the opportunity to open up and warm up over the course of the season. Obviously, Caitlin's a little bit colder in the pilot, and we do have some flashbacks coming up I believe in Episode 20, where you do get to see a little chillier side to Caitlin again. So I feel lucky that they've given me so many places to go this season."??
