The Flash Season 4 Episode 20 Therefore She Is

As the season draws closer to its conclusion, The Flash brings us an episode filled with exposition and character development. Therefore She Is takes us into the past and present of The Thinker's character, giving us a glimpse into the motivations that brought him to this point.

The episode begins with Harry communicating with the team about his ongoing quest to cure his cognitive impairment, which has slowly been eroding his intelligence throughout this season. Through his connection with the cerebral cap that empowers Marlize's (The Thinker's) thought processing, Harry is able to deduce that Marlize had a hand in the development of The Thinker's metahuman powers. Using his technological expertise, the team, along with Cisco, are able to come up with a plan to build a device that can reverse the effects of The Thinker's powers, rendering him vulnerable.

In the past, we delve deeper into the backstory of Clifford and Marlize DeVoe, and how they first came to meet one another. The two of them were colleagues in a research project, during which they developed a bond through their mutual admiration for one another's intelligence. This connection eventually blossomed into a romance, and the two were soon married.

As the story progresses, it becomes clear how Marlize's influence has turned The Thinker away from his original goal. Originally, he was only interested in gaining power to be a benefactor to humanity, but under Marlize's sway, he became an egocentric villain obsessed with enforcing his superiority. Marlize's intention throughout the episode is to remind her husband of the good intentions that he had when he first invented the satellite weapons that he's now using to change the world.

Filled with flashbacks to the couple's past, the episode explores the dynamics of their relationship further, which leads to the most emotional moment of the season so far. After Marlize is drawn back into The Thinker's plan, Barry must confront her in order to escape capture. During the showdown with Marlize, she realizes that she can no longer be with her husband and will have to fight against him in order to protect everyone.

The Flash season 4 episode 20 is therefore an episode that is heavy on exposition but still succeeds in developing the storylines of the season's main characters in a meaningful way. The relationship between Barry and Iris deepens as they work together to save Harry's mind, while the audience is able to gain a greater insight into the motivations of The Thinker and Marlize. Overall, it's a thrilling episode that sets up the rest of the season well.
