With metahumans streaming in through the breach caused by the singularity event, Earth-2 has loomed over "The Flash" since the season two premiere. Now, Grant Gustin -- who plays the Flash himself -- has teased that the Earth-1 team is about to head over and see Earth-2 for themselves (via Entertainment Weekly).

"It sounds like we're going to be making an Earth-2 trip in the future at some point this season," Gustin shared. "I don't know which characters are going to be going. I'm pretty sure Barry will be one of them. I don't know if we're going to see his doppelganger when we go over there. I'd imagine we would."

So far, only two Earth-2 doppelgangers have made their way to Earth-1: Linda Park and Harrison Wells. However, chances are better that Team Flash might bump into their other selves once they crossover. Jesse L. Martin, who plays Joe West, also hinted that he knows a little bit about his character's doppelganger.

"Earth-Two Joe might have a little musical element to him," Martin teased. As he is an original cast member of "RENT," fans have been clamoring to hear Martin sing in the show -- and it seems Earth-2 might just fulfill that wish.

Starring Grant Gustin, Carlos Valdes and Jesse L. Martin, "The Flash" airs Tuesdays at 8 pm EST on The CW.
