Before heading to Earth-2, Barry closes all but one of the breaches so that Zoom has no other way to travel between the parallel Earths. Using the last breach at S.T.A.R. Labs, Barry, Cisco, and Dr. Wells travel to Earth-2, but there is a surge of energy that destabilizes the breach. That caused the trio to be stuck on Earth-2 until Caitlin and Jay are able to fix the speed cannon. Barry decides to impersonate his Earth-2 self to get more information on Zoom. He later meets Iris and Joe of Earth-2 and learns that Iris works for the CCPD, while Joe is a singer at a jazz bar. Barry is attacked by Earth-2's Caitlin and Ronnie Raymond, known there as Killer Frost and Deathstorm, agents of Zoom. In the attack, Joe is killed. Cisco attempts to help the police stop the pair, but is confronted by his own evil doppelgänger, "Reverb". Cisco discovers Reverb has greater power, including control over nervous systems. Barry tries to rescue him but is stopped by Reverb and Deathstorm. Zoom arrives, kills Reverb and Deathstorm for harming the Flash, and then imprisons Barry alongside Jesse. Meanwhile, Jay reveals to Caitlin that he invented Velocity 6 on his Earth and that it is the real reason why he lost his speed and is dying.


Promotional images[]



Cloud City Vadering me right now?" This is a reference to a famous scene from Star Wars Episode V – The Empire Strikes Back, when Darth Vader tries to convince Luke Skywalker to join him.

    • Moments later, Cisco tells Reverb that he will not go to the Dark Side with him, again referencing the Star Wars franchise.
  • Floyd Lawton's failed attack against Reverb is a reference to a scene from the movie Pulp Fiction.
  • During a broadcast on Earth-2, the mayor of Central City is referred to as Mayor Snart. This could be a reference to the Earth-2 counterpart of Leonard Snart, or another member of the Snart family.
  • When Cisco says, "I've seen fire and I've seen rain", he may be quoting lyrics from a song by the band Blood, Sweat & Tears.
  • Zoom takes out Reverb the same way Thawne killed Cisco in an alternate timeline in The Flash episode "Out of Time".
