It is revealed that H.R. swapped places with Iris, leading to his death. Savitar kidnaps Cisco and forces him to rebuild the Bazooka into an interdimensional quantum splicer so that Savitar could create fragments of himself to be dispersed throughout time and protect himself from the paradox. Barry tries to convince Savitar that he could be saved. Savitar returns to S.T.A.R. Labs, destroys it with the Philosopher's Stone and orders Caitlin to kill Cisco, but Gypsy interferes. Savitar and Caitlin open a portal into the speed force; the Black Flash appears and attacks Savitar, but Caitlin stops him with her powers. Savitar attempts to execute his plan, but Cisco actually modified the Bazooka into a skeleton key to free Jay from the speed force prison. Barry, Wally and Jay engage Savitar, while Cisco and Gypsy face off against Caitlin. Cisco convinces Caitlin to become benevolent. Barry phases through and destroys Savitar's suit before Savitar is shot by Iris, seconds before he is erased from existence. As Team Flash mourns H.R., Caitlin decides not to use Julian's cure, leaving in order to find her own purpose. A massive storm appears over Central City, created by the empty unstable speed force prison. Barry explains that he needs to accept his punishment for creating Flashpoint and enters the speed force prison himself, entrusting Central City to Wally and the team.
