“The Flash” star Grant Gustin confirmed what fans have suspected for several weeks. The CW drama will tackle the famous “Flashpoint” storyline from the comics in Season 3. However, he warned that it won’t be exactly as it was in the source material.

“I'm SO excited to get back to work in 2 weeks,” the actor, who plays Barry Allen, teased on Twitter. When executive producer Greg Berlanti tweeted that he could reveal the title, Gustin was more than happy to announce the news.

Viewers who watched the Season 2 finale suspected that “The Flash” would cover this comic book arc. The episode ended with Barry going back in time to save his mother’s life. That’s exactly what caused an alternate timeline in the “Flashpoint” story. Not everything will be the same in the TV show, though.

Gustin, who has read the script for the Season 3 premiere of “The Flash,” seems well-versed in the comic book mythology. He has read the books as well as watched the cartoon movie. He warned that the TV show version “will be its own thing.”

Of course, now fans are left wondering just how long the “Flashpoint” arc will last. CW President Mark Pedowitz previously teased that all four DC dramas “will join forces in our annual crossover event, our biggest ever,” for this winter. “The Flash” will crossover with “Legends of Tomorrow,” “Supergirl” and “Arrow.” It isn’t just Barry that will have to be on the right Earth in the right timeline. “Supergirl” takes place on another Earth as well, so it looks like the DC TV writers are going to have to get creative this winter.

“The Flash” Season 3 premieres Tuesday, Oct. 4 at 9 p.m. EDT on The CW.
