Realizing Iris is not dead, Savitar kidnaps Cisco and forces him to modify the Bazooka into an "inter-dimensional quantum splicer". This will allow Savitar to disperse himself throughout time and protect him from the paradox that threatens to erase him . Barry meets with Savitar, believing he can be redeemed and they go to S.T.A.R. Labs . Although Barry and Iris try to get through to him, Savitar wrecks the lab and orders Caitlin to kill Cisco, but Gypsy saves him . Savitar and Killer Frost open a portal into the Speed Force . The Black Flash intervenes, but is frozen by Caitlin . Savitar then attempts to execute his plan . However, Cisco modified the Bazooka into a' skeleton key' which frees Jay from the Speed Force prison . Barry, Wally and Jay engage Savitar, while Cisco, with Gyspy's help, convinces Caitlin to abandon Savitar . Barry phases through and destroys Savitar's armor before Savitar is erased from existence . As Team Flash mourns H.R., Caitlin decides not to use Julian's cure, leaving the team so she may find her own purpose . Later on, an energy storm appears over Central City, caused by the Speed Force prison being empty . Barry explains that he needs to atone for creating Flashpoint and enters the prison, entrusting Central City to Iris and the team . </Td> </Tr> <Table> <Tr> <Th> No . overall </Th> <Th> No. in season </Th> <Th> Title </Th> <Th> Directed by </Th> <Th> Written by </Th> <Th> Original air date </Th> <Th> Prod . code </Th> <Th> U.S. viewers (millions) </Th> </Tr> <Tr> <Th> 70 </Th> <Td> </Td> <Td> "The Flash Reborn" </Td> <Td> Glen Winter </Td> <Td> Story by: Andrew Kreisberg Teleplay by: Todd Helbing & Eric Wallace </Td> <Td> October 10, 2017 (2017 - 10 - 10) </Td> <Td> T27. 13401 </Td> <Td> 2.84 </Td> </Tr> <Tr> <Th> 71 </Th> <Td> </Td> <Td> "Mixed Signals" </Td> <Td> Alexandra La Roche </Td> <Td> Jonathan Butler & Gabriel Garza </Td> <Td> October 17, 2017 (2017 - 10 - 17) </Td> <Td> T27. 13402 </Td> <Td> 2.54 </Td> </Tr> <Tr> <Th> 72 </Th> <Td> </Td> <Td> "Luck Be a Lady" </Td> <Td> Armen V.
