"Therefore She Is" is the twentieth episode of the fourth season of The Flash, and the eighty-ninth episode overall. It aired on May 1, 2018.

  • The title of this episode is similar to the title of the seventh episode of the fourth season, "Therefore I Am".
    • Similar to that episode, this episode features flashbacks of the DeVoes.
  • Discovering DeVoe's plan, Cisco likens him to a James Bond villain.
  • The manner in which DeVoe attempts to choke Gypsy by using Janet Petty's gravity-bending powers to apply pressure around her throat is similar to the way Darth Vader, from the Star Wars franchise, uses the Force to choke others.
  • Joe mentioned that Wally gave him and Cecile a bassinet that once belonged to Moses. This is a reference to Wally's time traveling adventures with the Legends, which were seen in the third season of DC's Legends of Tomorrow.
  • The Mystery Girl is revealed to also be a speedster.


  • The flashback when Clifford and Marlize first danced together is listed as 8 years prior to this episode, which would place it in 2010. However, in a continuity error, Clifford mentioned in "The Trial of The Flash", that he and Marlize first danced together on June 13, 1997.
