In order to become The Flash again, Barry is going to have to recreate the particle accelerator explosion which gave him his powers in the first place, but what kind of deadly consequences could that end up having? Time will tell on that front, but below you will find a sneak peek at what's to come when the team attempts to reunite the former Fastest Man Alive with the Speed Force in order to stop Zoom.
Zoom (guest star Teddy Sears) arrives back on Earth-1 intent on taking over Central City. Barry (Grant Gustin) 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 (guest star 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 (guest star 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. Armen V. Kevorkian directed the episode written by Kai Yu Wu & Lauren Certo.
