"The Flash's" Earth-2 problems will continue into next month, as a new synopsis for an upcoming episode of the CW series reveals. Not only will Zoom (Teddy Sears) find a way back to Earth-1, thus putting Barry Allen (Grant Gustin) in a dangerous predicament, but Cisco (Carlos Valdes) will get a glimpse of his brother Dante's (Nicholas Gonzalez) evil Earth-2 counterpart.

In the comics, Rupture is the villainous codename used by Cisco's other brother Armando. This isn't the first time that the Ramon brothers have shared codenames upon making the jump from the page to the screen; in an earlier episode of the series, Cisco's evil Earth-2 counterpart went by the codename Reverb, which is the other codename used by Armando Ramon in the comics.

The "Rupture" synopsis also reveals that John Wesley Shipp's Henry Allen will return to give Barry advice on how to handle his supervillain problem. "Rupture" airs on the CW at 8 PM on May 3rd.

"Rupture" - (8:00-9:00 p.m. ET) (TV-PG, V) (HDTV)
DC COMICS' CHARACTER RUPTURE COMES TO CENTRAL CITY WITH 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 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. Armen V. Kevorkian directed the episode written by Kai Yu Wu & Lauren Certo (#220). Original airdate 5/3/2016.
