According to Entertainment Weekly, Team Flash will be spending quite a bit of time on the Earth next during the remainder of Season 2. That also means we’ll be seeing more of Caitlin’s Snow’s doppelganger, the meathuman Killer Frost, though her exact fate after rebelling against Zoom remains unclear:
First off, despite the final breach being closed, we have not seen the last of Earth-2. “You’ll see quite a bit” in coming episodes, executive producer Todd Helbing says. As for Killer Frost, we will find out her fate, so yes, you will see her again sometime soon.
The Flash airs Tuesdays at 8 p.m. ET on The CW.
