Killer Frost might be here to stay. In an interview with Entertainment Weekly, "The Flash" executive producer Andrew Kreisberg and star Danielle Panabaker discussed Caitlin Snow's villainous turn, the potential for Killer Frost's future in the "Arrow"-verse and more.

“It’s now a question of: Is there a way to eliminate these powers and get Caitlin back?” Kreisberg said. “Is there a way to get Caitlin back and leave her with these powers? We say these last few episodes are about them trying to save Iris’ [Candice Patton] life, but they’re also trying to save Caitlin’s soul. What is Cisco [Carlos Valdes] willing to do to save his best friend? What is Julian [Tom Felton] willing to do to save the woman he loves?”

"I don’t know what their future looks like," added Panabaker. "In last week’s episode, you get the sense that Julian is willing to do whatever he can to bring Caitlin Snow back. It’s just going to be this struggle of Caitlin Snow vs. Killer Frost, who’s going to win out?”

“Team Flash has thrown everything they can at her, whether it was the metahuman cuff or the necklace, to keep Killer Frost suppressed. Now that Killer Frost is free, I don’t think she’s interested in going away nicely," she explained.

She also revealed that she has a major part to play in the Season 3 finale. “Obviously I am involved a little bit more in the finale this time than I have been in years past. From a totally biased perspective, it’s great to see a lot more of the familiar faces," she shared. "Last year, it was Barry vs. Zoom, and obviously this year there’s a lot more speedsters, there’s a lot more powers, so invariably, I think you’re going to get to see a bigger, better battle.”

“Obviously Danielle Panabaker is not going anywhere. How and if she becomes Caitlin Snow again, or she remains Killer Frost or a version of Killer Frost, into season 4, you’re going to have to tune in,” Kreisberg teased.

“For me personally as an actor, it’s been fun to play Killer Frost and I hope that it lasts a little while and we don’t necessarily tie it up in a bow right away,” Panabaker said. “I’m enjoying getting to play her.”

Starring Grant Gustin as the Scarlet Speedster, “The Flash” airs Tuesdays at 8 pm ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
