SPOILER WARNING: This article contains spoilers for The Flash Season Three finale.
The third season finale of CW's The Flash saw Barry Allen and his team of crime fighters finally defeat the villainous Savitar, but their celebration was short lived as the group soon discovered the price of their victory. With the Speed Force no longer in balance due to Savitar's absence, Barry sacrificed himself and took the antagonist's place, leaving behind his friends and comrades. Naturally, season four will see the speedster eventually make his way back to Central City, but the Barry Allen who escapes the Speed Force might not be the same guy who entered, according to Flash star Grant Gustin.
"Barry, when he comes out, won't be himself initially, because of how insane this experience is," Gustin said in an interview with CinemaBlend. "This Speed Force experience isn't like the past where we've seen him in the Speed Force. We've seen the Speed Force embody other people in his life and teach him whatever lesson they think that he needs to learn at that point. This time, I think he's kind of been left on his own and he's been experiencing a non-linear timeline of his life over and over again from start to end, in really no particular order."
Gustin then added that he feels this very different stint in the Speed Force will alter Barry's mindset and outlook on his metahuman acts both past and future. "So I think when he comes out, he's kind of jumbled and messed up initially, but once we get past that, I think he's had this sense of awakening and understanding. He's been able to let go of a lot of the loss in his life, and forgive himself for a lot of the mistakes he made last year that sent the whole team down the road they went down."
The show's fourth season is beginning to sound more and more like a soft reset for the series, which will excite many viewers who took issue with season three. The new arc's big bad will not be a speedster, with Team Flash now having to contend with the Thinker for the forseeable future, as well as Danny Trejo's Breacher.
Returning Tuesday, Oct. 10, at 8 p.m. ET/PT on The CW, The Flash stars stars Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin and Keiynan Lonsdale.
