Last night on the Arrow season finale (which okay, hello Olicity!) The CW showed it’s first full teaser trailer for the upcoming crossover series The Flash. The Flash will star Glee‘s Grant Gustin as the adorable (and super fast) Barry Allen. Oliver Queen last saw Barry in a coma after he was struck by lightning – but it looks like Barry is doing okay now!
UPDATE: The CW has also released an extended trailer! Enjoy all its flashy goodness below.
