The Flash's Andrew Kreisberg opens up about how Barry Allen will fit into Supergirl

Some new information concerning the hotly anticipated Supergirl/The Flash crossover event set to zoom across our television screens in less than two weeks has emerged.

In a new (and lengthy) article with Entertainment Weekly, Andrew Kreisberg — who serves as an executive producer on both CBS' Supergirl and The CW's The Flash — explained how Barry Allen (Grant Gustin), the Fastest Man Alive, will end up in Kara’s (Melissa Benoist) world in the Supergirl episode “Worlds Finest.”

So, how will Barry temporarily jump ship? By using a tachyon device that will cause him to run so fast, he will end up in an alternate universe (something that’s already been established on The Flash). Kreisberg says the trip will only take a sec on The Flash, but our Scarlet Speedster will spend a day in National City, where he’s shocked to discover another superpowered superhero who's not an evil metahuman. 

“Supergirl has never heard of The Flash and Flash has never heard of Supergirl, so there’s a lot of like, ‘Wait, you’re the who, now?’ ” says Kreisberg. The comedy, in that sense, hits the ground running with the classic tale of boy saves girl, girl miraculously flies away, didn’t need saving in the first place. “Barry and Kara take a little bit of a leave of their problems for a week to engage in the kind of hilarious high-stakes high jinks that ensue when two super­heroes wind up in the same universe,” Kreisberg says.

Benoist went on to talk about how Barry and Kara will be quick to trust one another based on the fact that even though they both lost their parents at a very young age, they’re still fun-loving geeks who haven’t let their dark past define them unlike, say, Batman. (Darkness. No Parents!)

“What’s so wonderful about these two characters in particular is that they’re so joyful and happy to be heroes,” Benoist says. “There’s this mutual understanding, respect, and excitement that they found each other.”

Following Kara’s temporary turn to the Dark Side of the Force (thanks to some Red Kryptonite) in this week's episode of Supergirl, Kara is currently not very well liked by the people of National City. “She’s fallen out of good graces with the people at National City,” Kreisberg says. “The Fastest Man Alive’s advice, ironically, is to slow down and let things come to you.”

With Benoist adding about their new-found kinship “He teaches her quite a bit about what it means to be a hero, what kind of hero she wants to be, and even personally about love, friendship, and being true to who you are,” Benoist says. “It feels really good for her to have someone to relate to.”


Barry’s arrival in National City not only helps the Maiden of Might renew her purpose as a superhero, but it also helps Barry get the shot in the arm he needs in his fight with Flash villain Zoom, recently revealed to devastating effects as Jay Garrick/Hunter Zolomon (Teddy Sears).

“He’s able to realize that he has more experience than he gives himself credit for,” Gustin says. “That makes him come back with new confidence and this happiness because of this new friend that’s out there.” And possibly a love interest? “We tease it a little bit,” Gustin says. “He’s in town for a day so there’s not really time for anything to actually develop, but there’s undeniable chemistry, and they have a lot of things in common that they’ll never have in common with anybody else, obviously. This is the first person with powers Barry [has met] who’s using them for good. It happens to be somebody that he is attracted to, so it’s cool.”

As to the age-old question of who’s the fairest fastest of them all, viewers will see Supergirl and the Scarlet Speedster address it head-on, just like Flash and Superman did in the 1967 Superman #199 comic book which depicted “The Race Between Superman & Flash!” Since the show's about Supergirl and not the Man of Steel, it now becomes, for the purpose of the TV crossover, “The Race Between Supergirl & The Flash!”

“It’s one of my favorite moments in this episode,” says Kreisberg. “It’s close.” Hopefully close enough that they’ll need a rematch next season, maybe with Green Arrow and the Legends as an audience. “That’s in the cards at this point,” says Gustin. “The whole point of us doing this crossover is setting up the fact that maybe next year we can cross over all of them.”

The Supergirl episode “Worlds Finest” is set to air March 28 on CBS. Are you excited about the upcoming meet cute between the two iconic DC Comics heroes and them striking a lasting superfriendship?
