Grant Gustin, the lead actor of ‘The Flash,’ recently disclosed that he had a contrasting vision of the show’s ending from the showrunner Eric Wallace. In an interview with TVLine, Gustin revealed that he initially wanted Barry Allen’s character arc to culminate with a selfless and valiant demise, in line with a well-known fan hypothesis. The final season of ‘The Flash’ can be watched on The CW every Wednesday.
Grant Gustin shared that he had envisioned a different ending for Barry Allen’s story in The Flash. He mentioned that there was a popular fan theory that he liked, which would bring the story full circle by having Barry sacrifice himself to keep the Speed Force alive and become the lightning bolt that initially gave him his powers. Gustin had hoped for Barry to die a hero’s death, but showrunner Eric Wallace was against the idea and preferred a happy ending for Barry and Iris. Unlike Supergirl and Black Lightning, which had happy endings for their heroes, the Arrowverse has seen heroes make sacrifices, such as Stephen Amell’s Oliver Queen who died during the “Crisis on Infinite Earths” crossover event.
Gustin Optimistic About Fans Being Satisfied with the End of the Show

Grant Gustin expressed confidence that the conclusion that showrunner Eric Wallace has in mind for “The Flash” will leave fans feeling fulfilled. Gustin added that concluding on a positive note is pleasant and leaves the door open for future possibilities. The story may end, but the world it has created will live on.
The Chilling Foreshadowing of Barry Allen’s Demise in The Flash
Barry Allen met his demise in the Crisis on Infinite Earths plotline in the comic books, but he eventually came back in the sequel Final Crisis in 2008-2009. While Grant Gustin’s portrayal of Barry has a happy ending, the show hinted at a similar fate for him. In the first episode, Harrison Wells/Eobard Thawne (Tom Cavanagh) gazed at a newspaper from 2024 that foretold the Flash’s disappearance in the “Crisis.”

In the show’s fifth season, Barry’s daughter Nora West-Allen (Jessica Parker Kennedy) disclosed that he never returned after vanishing, and she grew up without him. Before “Crisis on Infinite Earths,” the Monitor (LaMonica Garrett) informed Barry that he would die. However, it was the Barry Allen portrayed by John Wesley Shipp from the 1990-1991 The Flash television series who perished in the “Crisis.”
