The Flash fans were shocked when last week’s episode, “I Know Who You Are,” revealed that the villain Savitar was actually Barry Allen from the future. However, it turns out fans were warned about this turn, and they were warned by Barry himself.
The warning came during the “Invasion” crossover story in the fall, which brought together cast members from Supergirl, The Flash, Arrow, and Legends of Tomorrow. During the crossover, time traveler Rip Hunter received a message from a future Barry Allen warning Rip not to trust anyone in the future, including Barry himself.
This warning is connected to the Savitar reveal, and that won’t go unmentioned on The Flash.
“Someone does point out that suddenly that message makes a lot of sense,” executive producer Andrew Kreisberg tells Entertainment Weekly.
In the next episode of The Flash, “Cause and Effect,” Barry (Grant Gustin) takes drastic measures to stop Savitar. Meanwhile, H.R. (Tom Cavanagh) continues to push Tracy Brand (guest star Anne Dudek) to design the trap for Savitar and Killer Frost (Danielle Panabaker) returns with an interesting proposal.
“Cause and Effect” is directed by David McWhirter from a script by Judalina Neira & Lauren Certo.
The Flash airs Tuesdays at 8 p.m. ET on The CW.
After successfully closing the Singularity from destroying Central City, Barry thinks he’s seen the worst… but the arrival of Jay Garrick (Teddy Sears) reveals that the Singularity actually opened portals to an alternate Earth, known as Earth-2, which is being terrorized by a formidable evil speedster named Zoom. As Zoom sends an army of Earth-Two meta-humans to Earth-1 to defeat Barry, he receives unexpected assistance from the Earth-Two doppelganger of his former mentor, Harrison Wells. Meanwhile, Cisco discovers that he, too, was affected by the dark matter of the Particle Accelerator and must come to terms with his newfound powers. As Barry struggles to juggle life as a hero, he opens his heart to Patty Spivot (Shantel VanSanten), a spunky detective paired with Joe West, but realizes just how hard it is to find happiness when the lives of everyone you love are at stake. He finds some solace in the companionship of his father, Henry Allen, who was freed from a wrongful life sentence... but when Zoom kills Henry before Barry’s eyes, Barry’s newfound stability is shattered.
Blinded by anger, Barry unwittingly plays into Zoom’s game and uncovers the evil speedster’s true goal: to destroy all Earths in the multiverse. In the race of his life, Barry ultimately gets the upper hand against Zoom and defeats his nemesis. But unable to celebrate victory, Barry makes a world-shaking decision and speeds back in time to the night his mother died to stop Reverse Flash from killing her, irrevocably changing his past and redetermining his future.
