Ep 22. Think Fast

In the penultimate episode of The Flash (2014) season 4, titled "Think Fast," viewers are thrown into the aftermath of DeVoe's enlightenment. The episode opens with Team Flash scrambling to regroup after Clifford’s (DeVoe’s real name) world-ending event, which has left Barry (the Flash) feeling helpless and guilty.

DeVoe’s ultimate plan has been revealed: to create a new world order with himself at the top, using the stolen powers of the Bus Metas (individuals with metahuman abilities from the bus that was hit by dark matter). To do so, he uses a device that allows him to switch between the bodies of various metahumans, draining their powers and leaving them for dead in the process. The device, which he previously revealed to be a "thinking cap," is revealed to be much more powerful than the team initially believed.

The episode is heavily focused on DeVoe, who is clearly in a state of delirium as he struggles to maintain his grip on reality. Meanwhile, Team Flash is split up, each member dealing with their own struggles as they come to grips with the new world order. At the same time, they are looking for a way to stop DeVoe and save the world.

Barry, Cisco, and Caitlin work together to figure out a way to stop DeVoe's endless switching of bodies. They find that, while in the process of switching, DeVoe is vulnerable and can be taken down. They devise a plan to use the powers of the remaining metas outside of DeVoe's reach to defeat him. Meanwhile, Iris and Harry team up to try and rescue Marlize (DeVoe’s wife), who has been keeping herself hidden from her husband after realizing his plans.

As the tension builds, the stakes become higher and higher. The episode features some truly emotional moments, highlighting the impact that the events of the season have had on each of the characters.
