"The Flash" EP Discusses Potential of Encountering Earth-1's Supergirl

Throughout "The Flash's" second season, Barry Allen has encountered more than his fair share of doppelgangers thanks to the breach between parallel universes he inadvertently created in the season one finale. However, on one of his trips through the multiverse, he encountered someone he'd never seen before: Supergirl. Now that Supergirl and the Flash have teamed up, fans are wondering if we'll see Earth-1's version of Supergirl any time soon. According to executive producer Andrew Kreisberg, there's potential for it.

"Any Kara that exists on Earth-1 would also have to have been an alien," Kreisberg explained to Entertainment Weekly. "It can't just be Kara Danvers from Poughkeepsie."

When asked if that means there's potential for a Supergirl on Flash's Earth, he said, "Sure. Different costume, but sure."

Starring Grant Gustin, Carlos Valdes and Jesse L. Martin, "The Flash" returns Tuesday, April 18 at 8 pm EST on The CW.
