Killer Frost might not be reverting to Caitlin Snow anytime soon, as the character may continue to pose a threat well into next season of The Flash.
The next episode will see Killer Frost return to cause trouble for our heroes, and she won’t be defeated anytime soon.
After Killer Frost appeared last season as a villain over on Earth 2, our version of Caitlin Snow has been slowly morphing into the ice-powered meta as well.
For almost three seasons now, the threat of metas has continued to grow on the Arrowverse series.
