Barry, Cisco, and H. R. visit Tracy to ask for her help in setting a trap for Savitar; they are interrupted by Killer Frost, who attempts to kill Tracy, but is defeated before she escapes. Tracy goes to S. T. A. R. Labs with the Flash team, and is shown her future. Later, the Killer Frost decides to kidnap Joe's girlfriend, Cecile, and demand Tracy in return. Frost's Killer plan fails, leading to a battle between her and Cisco. Defeated, she is carried off by Savitar, but not before Cisco takes some of her blood to potentially make a cure for her powers. Meanwhile, Joe confesses his love for Cecile and tells her about Barry and Wally's alter egos. Later, Tracy, inspired by these events, plans to build a trap for Savitar, while Barry gets a revelation regarding Savitar's identity, given how much Savitar knows about everyone, and confronts him outside the city. Savitar confirms Barry's new assumption and reveals himself to be a future version of Barry.
