In the next episode of "The Flash," viewers can finally see Killer Frost in action. Fans of the show are eagerly waiting to see if Caitlyn Snow (Danielle Panabaker) will leave Team Flash for good.

Killer Frost From Earth 2

This is not the first time Killer Frost made an appearance in "The Flash." She is the big, bad, not to mention cold villain who was working with Zoom in Earth 2. All the members of Team Flash are aware of what she can do with her powers. It is no surprise that they are a bit concern when Caitlyn finally revealed that she has powers.

Killer Frost Emerges

"The Flash" Season 3 episode 7 will focus on the evolution of Killer Frost. In one of the previous episode this season, Caitlyn's mother warned her about the irreversible effects every time she uses her powers, Movie Pilot reported.

Caitlyn chooses to ignore those warning and went on to save Barry from Savitar. She was successful in saving Barry, but as a consequence, she went on a rampage. She kidnapped CSI Julian Albert (Tom Felton) and she's even in a battle with Vibe (Carlos Valdes) and The Flash himself.

Bad One or The Good One

It remains to be seen if Killer Frost is really going to be this season's bad villain. Is she going to be a formidable addition to Team Flash or is she going to join Savitar and Alchemy in the fight against The Flash?

If Caitlyn will choose to dwell on her issues with her mother and the fact that she didn't have this power before "Flashpoint," there's a chance that she can never come back from being the bad version of Killer Frost. However, if she'll focus on the good - her friendship with the members of Team Flash, their mission to save the world against metahumans - there's a strong possibility that she'll remain with Team Flash. Caitlyn still has to figure things out for herself, which is her nature as a scientist, Collider reported.
