Watch The Flash Season 4 Episode 21 Full HD Online with SUB

After Harry is expelled from the Wells Council due to his declining intelligence, Cisco gathers the Garrison Council to try to come up with a way to stop Harry's loss of intelligence. The Flash team reluctantly goes to the Amulet for help, encountering a Norwegian in the process, although Berry insists that the Amulet should not kill. Eventually, the team is given a bomb made of Amunet metal that will be able to destroy one of Devo's satellites, and Harry manages to realize that Devo's plan may change because Marlise is no longer with him. Iris publishes an article revealing DeVoe's plan, and the residents of Central City begin to report sightings of Girls that Iris believes will prevent him from going unnoticed.
