Synopsis for "Fastest Man Alive"
As Barry chases after Thawne, he's joined by Wally, who tells Barry to push as hard as he can to break the time barrier. Doing so, they reach Thawne, becoming the lightning bolt that turns Barry into the Flash as they are able to stop the madman from killing Iris. As the two Flashes chase Thawne, he attempts to dissuade Wally by saying that one of his kids would make his life miserable in the future. Barry's heard enough and the trio pushes Thawne back through time, showing Thawne confronting young Iris, Thawne's dead body becoming a Black Lantern and Iris holding Barry's costume. Returning to the present, the two Flashes see that the Justice League, the Justice Society, the Outsiders, Wonder Girl and Superboy have built a device specifically for Thawne. Barry tosses him in and Jay activates the device, severing his connection to the Negative Speed Force. As the Flashes tie him up to stop him from running, Iris discovers Thawne's weapon and keeps it. With the threat ended, everyone celebrates by welcoming Barry back and the speedsters in general, though Jai seems despondent over the loss of powers.
In Iron Heights, as Dr. Alchemy escapes, Hunter Zolomon talks to Thawne, hoping for the two to work together. In Gorilla City, one of the apes warns that Thawne has done something horrible to their jungles, something even they don't know. Hidden elsewhere, another figure ominously says that Thawne should have made sure the person was dead. In Central City Police Precinct, Barry closes the case on his mother's death and opts to take all the other cold cases they had after his death. Elsewhere, the Rogues prepare to deal with Barry, Captain Cold saying "In case the Flash returns: "break glass". Barry spends some time with Iris before racing to Washington to celebrate his return with the Justice League, telling them sorry he was late.
