The Flash's Gideon may have a role to play in "Crisis on Infinite Earths," the upcoming five-show crossover between The CW's DCTV series.
Asked if Barry can learn more about "Crisis" from the AI, showrunner Eric Wallace told TV Insider, "You might get that answer in our season premiere." While this response isn't exactly a confirmation, it heavily implies that the Scarlet Speedster will do just that in the Season 6 premiere.
In the series, Eobard Thawne, aka Reverse-Flash, brought Gideon back in time with him. Since Gideon hails from the future, she is knowledgeable of some events that Team Flash has yet to experience for themselves. She also keeps track of changes in the timeline. Indeed, in the Season 5 finale, she tracked a "time flux" that moved "Crisis" up from April 24, 2024 to 2019.
It is unclear what Gideon knows about "Crisis," but Season 5 indicated she existed during the event. Last season, Barry and Iris' daughter Nora West-Allen watched a video he recorded before he disappeared. Barry left the video for his daughter with Gideon without any knowledge she visited him in the past, which suggests he used the AI during the unaltered "Crisis" timeline. As such, she may have some valuable information for Team Flash in Season 6.
Returning Tuesday, October 8 at 8 pm on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
