Last year around this time, The CW’s “Arrow” gave us the on screen debut of Barry Allen (Grant Gustin) in a two-parter that essentially served as a kind of prequel/backdoor pilot for what would become the network’s “The Flash” series. Now, a crossover is set to happen again only this time everyone’s got a costume.
The CW have released a bunch of photos from “Flash vs. Arrow,” the upcoming “The Flash” episode which is the first of a two episode crossover event which sees the two heroes squaring off. The episode goes to air on December 2nd, while “Arrow” episode “The Brave and the Bold” wraps up the crossover the next night on December 3rd.
