Zoom\'s metahuman army wreaks havoc across the city. Barry puts out several fires and takes out some of the metahumans to help the police. Back at S.T.A.R. Labs, Barry displays a level of confidence in stopping Zoom that concerns the team, and each of them attempts to convince him to be more cautious. Caitlin returns to the team, but not without emotional trauma from being kidnapped. A metahuman begins attacking various buildings around Central City using a sonic blast. Barry confronts the metahuman, who turns out to be Laurel Lance\'s doppelganger, "Black Siren". She initially gets the upper hand, but Barry is rescued by Wally, who is trying to help out in order to repay the Flash. The team creates a sonic amplifier tuned to the frequency of Earth-2 natives. They discharge it and render all Earth-2 metahumans unconscious, allowing Barry to apprehend them all at once, although Zoom escapes. Later, Zoom returns and kidnaps Henry in front of the team. Barry races after them, revealing his identity to Wally, and is forced to watch Zoom kill his father.\\n
