As "Crisis on Infinite Earths" comes to the Arrowverse, the events of that story won't just be limited to the crossover. The Flash showrunner Eric Wallace confirmed Season 6 will continue to deal with the consequences of the event after the crossover.
Wallace revealed just how "Crisis" and The Flash will connect at Comic-Con International in San Diego. "'Crisis' is not separate from any story throughout the entire 22 episodes," he explained. "Even after 'Crisis,' the fallout from it continues to build and screw with Team Flash. In the first pre-'Crisis' episodes, as the big bad is getting introduced, like we always do -- we will see a relationship of what’s coming in 'Crisis' with what’s happening to Barry, with what’s happening to the new big bad. They are all interrelated."
Wallace also talked about how the event ties into Bloodwork, the season's main villain. "Once we reveal the new big bad, especially once we get around episode 3,4, and 5, you’ll understand exactly why this big bad was chosen," he continued. "It’s very specific and only could have been chosen in this year of 'Crisis' because dread is hanging all over Team Flash -- dread, sorrow. The potential loss of not only your loved ones but the entire world. That’s not happy."
In the original Crisis on Infinite Earths maxiseries, Barry Allen died while keeping the multiverse safe from the Anti-Monitor's anti-matter cannon, leading his nephew and sidekick Wally West to become the new Flash at the end of the series. While the show probably won't go that route, even with the return of Wally in the sixth season, fans should remember the Arrowverse will never be the same again even after the "Crisis" has passed.
Returning Tuesday, October 8 at 8 pm on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
