‘The Flash’ Season 3 Finale Spoilers: Killer Frost Kidnaps Cecile; Fights With Vibe

The CW has released photos for "The Flash" Season 3 Episode 20, "I Know Who You Are," which revealed a fight between Killer Frost and Vibe. The images also revealed that the villain kidnaps Joe West's girlfriend Cecile.

In "The Flash" Season 3 Episode 20, Team Flash is on a mission to find a scientist named Tracy Brand. 2024 Barry Allen had revealed in Episode 19, "The Once and Future Flash," that she knows how to defeat Savitar. According to the synopsis from SpoilerTV, the team must find a way to get to her first before Killer Frost kills her.

However, in their determination to keep Tracy safe, they forgot to include those close to the team. Apparently, Killer Frost has an alternative plan when it comes to making sure Tracy does not help the team. She kidnaps Cecile in "The Flash" Season 3 Episode 20, perhaps in exchange for the scientist.

Comic Book Movie shared a couple of photos from "The Flash" Season 3 Episode 20 that shows Cecile tied to a chair. Killer Frost is with her so are Barry, Joe, and Tracy. It is unclear what happens in this scene, but the synopsis revealed that this experience brings Joe and Cecile's relationship to a big turn. Perhaps Joe finally tells her about his metahuman family.

Likewise, the photos tease an epic fight between Killer Frost and Vibe in "The Flash" Season 3 Episode 20. Cisco arrives on the scene in full Vibe getup. Fans may remember that Cisco saw himself fight Caitlin when he vibed her. Episode 19 also gave a glimpse at their duel, which did not end well for 2024 Cisco--he lost his hands. Likewise, the trailer revealed Vibe and Killer Frost go head-to-head.

Meanwhile, "The Flash" Season 3 Episode 20 will finally reveal the identity of Savitar. The promo below teased that Barry finally discovers who he is. Speculations are rife that the God of Speed could be Caitlin Snow's dead husband Ronnie Raymond aka Firestorm.
