In “Rupture,” Zoom (Teddy Sears) arrives back on Earth-1 intent on taking over Central City.
Barry and Wells (Tom Cavanagh) come up with a plan to stop Zoom once and for all but it’s extremely dangerous.
Unsure if he should take the risk, Barry reaches out to both fathers for advice. Henry (John Wesley Shipps) is adamantly opposed to Barry risking his life again but Joe (Jesse L. Martin) thinks he can handle it which puts the two men at odds with each other.
Meanwhile, Cisco (Carlos Valdes) is shocked when he vibes the Earth-2 villain Rupture, who happens to be his brother Dante’s (Nicholas Gonzalez) doppelganger.
Rupture came to this Earth seeking justice for Reverb’s death. Iris (Candice Patton) decides she’s finally ready to open up to Barry about her feelings for him.
Barry (Grant Gustin) suits up despite being vulnerable in this still from tonight’s all-new episode of The Flash.
In “Back to Normal,” a meta-human with super strength named Griffin Grey (Haig Sutherland) mistakes Harry (Tom Cavanagh) for Earth-1 Harrison Wells and kidnaps him, demanding that Wells cure him from his current condition.
Realizing another brilliant Wells could help track Griffin’s location, Barry asks Jesse (Violett Beane) to help.
In “Flash Back,” after the shocking revelation that Zoom is Jay Garrick (Teddy Sears), Barry (Grant Gustin) is more determined than ever to get back to Earth-2 to stop Zoom forever.
Desperate to find a way to increase his speed, Barry decides to travel back in time and masquerade as his earlier self in order to get his arch-nemesis, Dr. Harrison Wells/Eobard Thawne (Tom Cavanagh), to teach him how to run faster.
However, things don’t go as planned and Barry is stunned to face familiar foe Hartley Rathaway (Andy Mientus), as well as old friend Eddie Thawne.
Iris (Candice Patton) makes peace with her past in order to embrace her future.
