When May comes around The Flash and Arrow will reach their big season finales, and we know the dates it all comes to an end…
… of the season.
The Flash and Arrow have been very successful for The CW and Berlanti Productions, and have been directly or indirectly responsible for Supergirl, and the upcoming Flash/Arrow spin-off series featuring The Atom, Canary, and Captain Cold. As the seasons wrap, we have learned that Arrow will wrap first, closing its season on May 13th, while The Flash will give us a major cliffhanger on May 19th.
