But for now, viewers of the hit DC Comics-based shows will have to be content with the first teaser for the two-part storyline which finds Oliver Queen arriving in Central City to train his friend, Barry Allen, while helping the nascent hero solve a mystery. Of course, when the two get together, they have something else they need to figure out -- which one would win in an all-out fight?
Both series are known for their extended sub-plots, and even though they're placing the team-up at the forefront for two hours, viewers can expect the development of long-simmering storylines to continue. "There's a really big character, emotional moment for Oliver on 'The Flash' side; [something] that we set up last season and paid off in 'Flash,' and will pay off down the road on 'Arrow,'" Kreisberg said of the crossover in a recent interview.
"It's like the bomb underneath the table," added EP Marc Guggenheim. "And I think part of the fun is waiting to see when Oliver is going to learn what the audience learns on 'Flash.'"
"The Flash" and "Arrow" crossover event begins Tuesday, December 2 at 8PM, 7PM Central.
