The CW has officially released the official synopsis for The Flash season 3 which is set to premiere on 4 October at 8pm EST. The third season of the show will feature Flashpoint timeline after Barry Allen went back in time and saved his mother from Reverse-Flash in season 2 finale.
The Flash season 3 episode 1 is titled, Flashpoint and the official description reads as follows:
Barry (Grant Gustin) is living his dream life – his parents are alive, he's asked Iris West (Candice Patton) on a date and he can finally be a normal guy as Central City has another speedster, Kid Flash (Keiynan Lonsdale), running around saving the city. When Barry starts forgetting parts of his old life, the Reverse Flash (guest star Matt Letscher) taunts his nemesis and tells him that there will be serious repercussions for Barry and the ones he loves if he continues to live in this alternate universe. In addition to losing his memories, his powers will also start to fade. When disaster strikes, Barry must decide if he wants to continue to live in this world as Barry Allen or return to his universe as The Flash.
Executive producer Aaron Helbing and Todd Helbing spoke to E! Online about Barry's life in Flashpoint timeline. Speaking about Barry's mindset in episode 1, Aaron Helbing said, "He's over the moon at the moment because his dream came true. He's living with his parents and he gets to see them every day,"
Todd Helbing then added, "There're consequences to every decision you make, and with Barry, it's a lesson that he keeps learning over and over, especially when it comes to time travel—the consequences are sometimes a lot more severe than you expect."
The producers also dished on how Flashpoint timeline would affect or change other characters in the show. Todd explained, "I would say as different as their doppelgangers were on Earth-2. Cisco is basically working at S.T.A.R. Labs in season two at a company that doesn't really exist. He's doing it to stop metahumans. And now he's a money-grabbing tech guy who doesn't give a s**t, so I would say he's a little bit different!"
Aaron added, "Caitlin is still a doctor, Joe is still a detective, Iris is still a reporter. Cisco's probably the biggest departure, and then there's Kid Flash."
