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.
