'The Flash,' 'Supergirl' crossover news: Greg Berlanti teases another crossover


“The Flash” and “Supergirl” executive producers Greg Berlanti and Andrew Kreisberg recently revealed more new details about the upcoming and much awaited crossover episode of the two series, which will happen in the upcoming Monday episode of “Supergirl.” The showrunners talked about the crossover’s relevance to the overall events of the two shows, how the events will fit into the sequence of events for the series, and the possibility of doing another crossover the other way aroundwith “Supergirl” visiting the world of “The Flash” instead.

According to a report by The Hollywood Reporter, Berlanti and Kreisberg revealed that users should pay close attention to the crossover events for there is one catch in watching them: the episodes are airing out of order. Also, the events that will take place in the episode would not be a mere filler or of no significance to The Flash in his quest to become faster than ever.

“They flip order, obviously, because this will air Monday and ‘The Flash’ one that sort of hints at how he gets over there and gets back airs on Tuesday,” Berlanti said in the press screening event for the crossover episode. “The audience has to forgive us because one has to air before the other, but they shouldn’t wait to watch ‘Supergirl’ until after ‘The Flash’ episode. They should certainly watch it before. But you’ll see the shout out in the episode. It deals with Barry increasing his speed and we’re very excited about next week’s episode of ‘The Flash,’ too.”

However, Berlanti added that this twist in the order of events as they happen is merely the small price viewers have to pay in making this crossover event possible, which had been one of the most requested things regarding the shows ever since “Supergirl” began on CBS.

“Had it been all on one network, we would have been able to coordinate that,” he added.

Additionally, Berlanti teased the possibility of doing another crossoverthis time, with Melissa Benoist’s Supergirl flying over to Barry Allen’s world in Central City. However, that will be based greatly on how fans will receive the upcoming episode.

“We would love that,” Berlanti said. “We’re waiting to see the audience’s reaction from something like this.”

“The Supergirl” and “The Flash” crossover episode “Worlds Finest” will air on CBS on Monday, March 28.
