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 Shipp) 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.
