So far on The Flash this season, fans have seen only brief glimpses of Earth-2, the alternate world from which Jay Garrick, Harrison Wells and most of the seasoin's villain's originated.
According to EW, though, that's going to change as Barry Allen will be making the trip across the vibrational barrier.
“It sounds like we’re going to be making an Earth-Two trip in the future at some point this season,” series star Grant Gustin told the magazine. “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 doppelgänger when we go over there. I’d imagine we would.”
The most likely scenario, of course, is that Barry and Harrison Wells might team up to head over to Earth-2 in search of Jesse Quick, Wells's daughter who is being held hostage by Zoom. Then again, Jay Garrick and/or Wells, who come from that world and are part of Team Flash this year, could have need or something over there.
So far, the Breaches have only gone one way: from Earth-2 to here. This indicates that Vibe and company might soon improve the technology.
The Flash airs on Tuesday nights at 8 p.m. ET/PT on The CW.
