The Flash Season Finale leaves room for the Multiverse in Season 2

The first season of CW's The Flash has officially ended. The season finale aired on last night and ended with a cliffhanger that might not have been too noticeable to every viewer. In the finale (Spoiler) Barry Allen/The Flash travels back in time to save his mother's life and keep his father from spending life in prison.

There's a problem with traveling back in time and changing things – you are also changing the future, thus creating multiple realities. In DC Comics' The Flash there are two fictional universes  – Earth-One and Earth-Two.

The cool thing about a Multiverse is the crossover potential. The comic has Aquaman, Green Arrow, Wonder Woman, Green Lantern, Hawkman and more making an appearance in Earth-One. Earth-Two has Jay Garrick – The Flash's counterpart (along with other heroes). The news of the Mutliverse was revealed by The Flash actor himself, "What's fun about this show is that there's going to be multiple timelines as we move forward," Grant Gustin told TVGuide, "I think we're going to start showing Earth-One and Earth-Two in the near future. There will be kind of different dimensions going on."

Different worlds can be as awesome, but also confusing. The Flash's crew recognizes that there might be some trepidation from the fans over whether or not the story will be consistent. Carlos Valdes, who plays as Cisco Ramon in the series assures that the writers won't leave room for unnecessary confusion. "It gets a little Rubik's Cube-y in terms of keeping consistency between all these timelines and whatnot," Valdes says. "But the writers have their stuff together. If I were to trust anyone, it would be them."
