As Killer Frost is just one aspect of Caitlin's personality, her death doesn't necessarily mean Danielle will be entirely off the show. Frost has been referred to as Caitlin's "sister," and in recent years, the relationship between the two has transformed from tumultuous to more symbiotic. Danielle also told TV Line that Killer Frost's death leaves a lot of potential for rational scientist Caitlin to have an emotional arc.

"She’s lost so much in her life already, and only recently come to a fairly symbiotic place with Frost,” Danielle continues. “They’ve certainly had their ups and downs over the years, so it’s going to hit Caitlin the hardest. And she’s going to grieve in a variety of different ways, which is realistic and authentic. ... There’s denial, anger, resentment. ... She’ll probably go through it all before the end of this season.”

Whether Danielle will exit the show for good remains to be seen. She concluded by saying she "hoped to be back" but that she was surprised The Flash had a Season 8 at all. "I think that emotionally, I, at least, was planning for Season 8 to be our last. But I’m grateful to the show and to the fans, and hopefully there’s more story to be told," she said.

There's another factor that could lead to Danielle's exit from the show: her pregnancy! In February 2022, Danielle revealed her second pregnancy in a series of posts on her Instagram. Like many working mothers, it's likely she will take a leave of absence when her child is born or when she gets closer to the due date.

Until then, fans will have to wait and see what happens! Catch The Flash on the CW on Wednesday nights at 8 p.m. EST.
