On Monday night, “Supergirl” and “The Flash” engaged in one of the most complicated TV crossover events in recent memory, with the CW speedster joining the CBS hero for a one-off adventure. Now, the minds behind the two shows (and a slew of other DC Comics TV series) are saying it might not be just a one-time pairing of Supergirl and the CW’s connected universe. 

“The Flash” Season 2 has dealt heavily with the concept of parallel universes and alternate Earths. As a result, it was easy to explain how Barry Allen (Grant Gustin) made it to National City to help Supergirl (Melissa Benoist). However, Greg Berlanti, an executive producer on “The Flash,” “Supergirl,” “Arrow” and “Legends of Tomorrow,” says The Flash may not be the only one capable of jumping dimensions. Speaking to E! Online, Berlanti was asked if another crossover may happen soon, to which he replied positively.

“We always wanted to do it, just because I think from the day we cast Melissa, [we had] the notion of her in scenes with Grant [Gustin] or someday, maybe in the best of all worlds, with Stephen Amell as well,” he said of the “Arrow” star. “It’s exciting to think of them on screen together.”

When pressed, he went on to admit that even the CW’s newest connected TV series, “Legends of Tomorrow,” has a built-in plot mechanism that would allow for the transfer between dimensions. In other words, not only are the producers behind “Supergirl” and the CW universe (often referred to by fans as the “Arrowverse”) open to another crossover, but it seems like they’re actively trying to make it happen. 

If fans were excited about another crossover with one of the popular heroes from the Arrowverse, it would likely require “Supergirl” to go beyond its first season. Although ComicbookResource notes that the show has been indirectly confirmed through rumors and insider sources, CBS has yet to make it official. In fact, some fans found cause for alarm when “Supergirl” was not on the recently revealed list of 11 shows renewed by the network. However, that doesn’t necessarily mean that “Supergirl” is in trouble, just that CBS is dragging its feet on an announcement one way or the other.
