The Flash Season 3, Episode 7 Synopsis: “Killer Frost”

This week on The Flash, Caitlin transforms into Killer Frost and wreaks havoc looking for Doctor Alchemy.

Last week, on The Flash‘s “Shade” episode,  A giant shadow meta was attacking Central City and it was to Team Flash to stop it. Caitlyn had her own personal battle though. With her abilities becoming more and more difficult to control, she confided in Cisco, and revealed her changing state.

As for Wally, his visions of Flashpoint got worse—all the way to the point where he had to be hidden away from Doctor Alchemy. However, Doctor Alchemy’s calls were too strong. The team finally decided to face Doctor Alchemy head on, and used Wally as bait.

Though Cisco promised to keep things on the down low for Caitlyn, he had to tell the rest of the team. Caitlyn was initially angered at the betrayal, but soon came around and saw things from Cisco’s perspective.

The team was eventually able to draw out Doctor Alchemy and what looked like a small cult of followers. However, right before apprehending him, another speedster showed up—calling himself “Savitar.”

Though Wally was saved from Doctor Alchemy, the stone Doctor Alchemy used still called out to him. Wally couldn’t resist and touched it. Did Wally become a speedster? Who is Savitar? And what will Caitlyn’s path to evil look like? We’ll find out this week. Here’s the official synopsis:

“Killer Frost”

"Caitlin uses her powers to save Barry (Grant Gustin) but as her mother predicted, the effort unleashes her inner Killer Frost. Killer Frost goes on a rampage looking for Dr. Alchemy, kidnapping Julian (Tom Felton) and battling both The Flash and Vibe (Carlos Valdes). Meanwhile, Joe (Jesse L. Martin) and H.R. (Tom Cavanagh) have a heart to heart talk."
