Ever since The Flash returned with a bang for Season 3 we've been eagerly awaiting to see just how massive the repercussions of Flashpoint were set to be, after Barry Allen (Grant Gustin) ran back in time to save his mother at the conclusion of Season 2. Unlike his last attempt, when he decided against saving her life for the greater good of the timeline, this time around he succeeded, and messed everything up by doing so (dammit Barry).
However, though Flashpoint was short lived, its effects were not. New metahumans and new dynamics have been springing up in the timeline we find Season 3 in, and looking forward there's some very exciting stuff happening indeed.
Before Season 3 even premiered we'd been promised that the new season would take us deeper into the life of one Dr. Caitlin Snow (Danielle Panabaker), a.k.a. that one member of Team Flash whose love life is even worse than Barry's plan to save his mother. And the upcoming episodes look like they're laying out something pretty special for Caitlin, and some big changes for the team.

It's Snow Joke
While we saw evidence of Caitlin's metahuman powers emerging earlier in the season, last episode — "The New Rogues" — introduced her frosty ice powers in a more explicit way than before, as she used them to secretly rescue Barry from Mirror Master's trap. The episode concluded with her accidentally freezing the water in her shower, emerging to discover that she had begun to develop the white hair and blue lips of Killer Frost — her evil Earth-2 doppleganger.
Thus the next episode — "Monster — is set to be pretty focused upon Caitlin as she grapples with her new powers. According to the official synopsis, "Monster" will take Caitlin to visit her as yet unseen mother — Dr. Tannhauser (Susan Walters), a renowned biomedical researcher — to seek help with her emerging metahuman powers.
But while Caitlin seeks reconnection and understanding from her mother, Dr. Tannhauser treats her like a test subject to be poked and prodded, and "Caitlin grows cold," dredging up memories from the past and rocking the relationship between the two. Following this up in a few episodes time we have Episode 7, the Kevin Smith directed "Killer Frost," so we know Caitlin is in for a rocky road heading forward.
Is Killer Frost Set To Return?
This won't be the first time the show has toyed with the idea of Caitlin struggling with her "dark side." Back in Season 2 episode "King Shark" Cisco (Carlos Valdes) returned from Earth-2 with knowledge of Killer Frost, and feared that Caitlin was beginning to demonstrate aspects of her doppelganger's personality. In reality Caitlin was just dealing with her grief over the apparent death of Jay (Teddy Sears), and took the opportunity to mess with Cisco over it, as would we all.
After donning the guise of Killer Frost earlier the season in an attempt to fool Black Siren (Katie Cassidy), it's looking pretty certain that Caitlin's powers — likely triggered by Barry messing with the timeline in Flashpoint — are going to somehow contribute to a personality transformation into the villainous Killer Frost.
Exactly why this will happen will need some explaining — merely developing powers does not a villain make. Cisco didn't go evil when he began to develop his powers as Vibe, nor did Barry, nor Jesse, nor Wally. So why Caitlin? Could it have something to do with the family secret that we'll learn of next episode?
But what if the Killer Frost of the Episode 7 title isn't actually referring to Caitlin herself? The original Killer Frost of The Flash — the Earth-2 Caitlin Snow — is currently presumed dead after she was stabbed by Zoom in retaliation for attempting to murder Caitlin, but perhaps she survived somehow. Perhaps she's still out there, still with a vendetta against Caitlin. Perhaps she finds a way through to Earth-1, or perhaps the show will take us back to Earth-2 to visit again.
So, could we see Killer Frost vs Killer Frost, or will Caitlin fall into the trope of the dark female and lose herself to her new powers? We'll get a little closer to finding out next week, when The Flash returns with Episode 5, set to air November 1, 2016.
