The Flash/Supergirl Crossover Is Happening March 28


Almost as soon as Supergirl was announced as a CBS show, fans started wondering: Would it be connected to the DC shows on The CW? The thought of a crossover with The Flash was especially enticing, but even with producers Greg Berlanti and Andrew Kreisberg as the bridge between the series, the logistical hurdles seemed too high to clear.

The outlook became a little sunnier a few weeks ago during the TCS press tour, and now what was just a pipe dream has become a reality. As revealed by Entertainment Weekly, the Flash/Supergirl crossover is happening, with Grant Gustin’s Fastest Man Alive set to appear on the March 28 episode of Supergirl.

Berlanti and Kreisberg thanked both the man who plays Barry Allen and the fans for helping the seemingly impossible become possible.

"We want to thank Grant Gustin for making the time to come visit (on top of his already immense workload) and all of the folks at CBS, The CW, Warner Bros., and DC for working this out. And finally thanks to the fans and journalists who have kept asking for this to happen. It is our pleasure and hope to create an episode worthy of everyone’s enthusiasm and support."

Now the big question is how the guest appearance will be explained in the show itself. The Flash has dealt heavily with the theme of alternate Earths in its sophomore season, with 52 portals opening up around the hero’s home of Central City. So far, all of those doors between dimensions have led to the same place, which the characters have dubbed Earth-2, but the concept of a multiverse has already been kicked around. Why couldn’t they discover a portal that led to the world of Supergirl?

There’s also an outside chance the producers and writers could simply imply that The Flash (along with Arrow and DC’s Legends of Tomorrow) have been taking place within the same fictional universe all along. That seems less likely because the characters haven’t made reference to each other yet, but it also hasn’t been established that they aren’t on the same world either. Supergirl has at least her cousin Superman in her circle, and Barry Allen and friends have mentioned other metahumans on more than one occasion as well.

No matter how they come together, this is exciting news for fans who want to see the two most hope-inspiring DC heroes on TV fight side by side. EW says there’s no indication that Supergirl would make a return visit to The Flash, but if this first cross-network crossover goes well, you certainly wouldn’t be wise to rule it out for next season.
