Watch The Flash Season 3 Episode 22 Full HD Online with SUB

24 hours before Iris ' death, the Flash team learns that there is only one power source that can power the "Speed Force Bazooka"; a salvaged Dominator technology owned by A. R. G. U. S. However, Lila refuses to hand it over due to her distrust of Barry due to his creation of Flashpoint. Barry then hires Snart from 1892, when he was traveling with the Legends, to help him infiltrate the A. R. G. U. S. and steal the device. In the process, A. R. G. U. S. agents capture Barry and Snart, but Lila, seeing the kindness in Barry's actions, lets him take the device. Snart advises Barry to use the kindness in him to defeat Savitar. Tracy decides to join the team. Cisco vibrates about his battle with Killer Frost and leaves to fight her. Joe hides Iris from Savitar on Earth-2 along with Harry and Wally, but Savitar tricks H. R. into revealing her whereabouts by pretending to be Barry, and then goes to Earth-2 and kidnaps her. Barry uses the "Speed Force Bazooka" on Savitar, but it fails when Savitar counteracts it with the Philosopher's Stone, which is made from calcined Speed Force energy. Savitar then stabs Iris in the back, apparently killing her before fleeing.
