Danielle Panabaker Opens Up About How Caitlin Is Handling Losing Killer Frost on 'The Flash'

Iris (Candice Patton) chats with Caitlin (Danielle Panabaker) for a bit in this new still from tonight’s all-new The Flash.

In the episode, not only does Citizen Cold (Wentworth Miller) return to help Barry (Grant Gustin) when he needs help transporting a dangerous meta – but Caitlin is mourning the loss of Killer Frost.

If you remember from last week’s episode, DeVoe actually used Melting Point’s ability to swap people’s DNA – and as a result, stole Killer Frost from her.

Danielle recently chatted with EW about the loss of Killer Frost, revealing that it’s not only taking a toll on Caitlin, but the team as well.

“It affects her a lot. Emotionally, it affects her, but also logically,” she says. “There is the scientist doctor inside of her who needs answers, so we’re going to see her try various different techniques to try and get Killer Frost to come out, and that does lead her to delve a little bit deeper into who Killer Frost is.”

On top of that, Caitlin isn’t able to “suit up” as Killer Frost to assist the team anymore either.

“It does frustrate her, for sure,” she adds. “There’s a moment in one of the episodes where Flash looks to Cisco and Caitlin and says, ‘Okay, suit up,’ and then he looks at Caitlin and he says, ‘Oh.’ It’s a sad moment where the team doesn’t have Killer Frost to rely on anymore.”

The Flash airs TONIGHT @ 8PM ET/PT on The CW.
