Grant Gustin talks with The Hollywood Reporter and said that The Flash will explore with time travel with the characters this season, which will lead to change the show itself.
“In comic books, when you start talking about time travel — if anybody has followed The Flash, then they know Reverse-Flash and The Flash are not just doing this right now in the present day,” he says. “They have a long history and there’s nothing that we’re not going to pursue when we try to tell the story. We’re trying to tell all of it.”
But if Gustin has his way, the time-travel element won’t be confined to season one. Gustin says time travel could potentially flip the show on its head for season two — though he stresses that’s up to the writers to decide.
“I think it would be fun if it totally changed the show for season two,” Gustin says.
