'The Flash ' Season 3 Spoilers: Episode 7 Will Feature The Return Of Killer Frost

It seems that it's Dr. Caitlin Snow's turn to be evil in "The Flash" season 3. In episode 7 of "The Flash" season 3, Dr. Caitlin Snow will turn into her Earth-2 doppelganger, Killer Frost.

According to International Business Times, the episode titled "Killer Frost" will have Snow in a battle with her friends The Flash and Cisco. She will also kidnap Julian, and look for Dr. Alchemy.

Dr. Caitlin Snow has been through a lot in "The Flash" series. In season one, she had to endure grief when she assumed that her fiancée Ronnie Raymond died in the blast. Although they briefly reunited and were even married when he was discovered to be alive, he sacrificed himself in "The Flash" season 2.

Dr. Snow also started getting close to Jay Garrick in "The Flash" season 2, only to discover he was actually the evil Zoom from Earth-2.

Now in "The Flash" season 3, Caitlin's ice powers are taking over. She was actually advised by her mom Carla to stop using her cryokinetic powers as they will soon become irreversible. But in "The Flash" season 3 episode 7, Dr. Caitlin Snow will again use her powers in order to save Barry.

This will cause her metahuman side, Killer Frost, to emerge and take over. She has long wondered about her potential to be evil when she first met her doppelganger in Earth-2. Now it seems that her fears are coming true.

The question is whether Dr. Caitlin Snow will forever be Killer Frost from now on. Will she join forces with Dr. Alchemy and be a new villain in the show, as speculated by Inquisitr? Or will her friends be able to save her and reverse the powers in "The Flash" season 3?
