Prepare next month as The Flash will team up with Supergirl. Could they be potential lovers?

According to EW, Barry Allen will make an appearance in National City on a Supergirl episode this coming March 28. The news was so overwhelming that leaving out the reason Grant Gustin ends up in Mellisa Benoist’s domain becomes less relevant. What’s important is the fact that a crossover is possible.

“We are so incredibly excited to announce something that we have dreamed of happening since we starting making Supergirl —The Flash and Supergirl are teaming up,” announced Andrew Kreisberg and Greg Berlanti, producers of both superhero shows.

The crossover was made possible thanks to many people who were open to the idea.

“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,” the execs shared.

Meanwhile, Kara Danvers making her way to Central City still remains to be seen.

Since crossovers between superheroes from shows of the same universe are possible, fans are hopeful and excited to see either of these shows to feature “Arrow” (another show written by Berlanti) as well. There may be no details about “Arrow-Supergirl-The Flash” crossover just yet but the premise is certainly possible in the future.

As was reported in Newsrama, the writer of the three series said, “I would love it, a lot of things would have to go right and people would have to say yes.”

Berlanti added that there have been talks regarding the crossover but these chats were not really official. He said, “It would have to figured out very soon. It would all have to be figured out in the next month or so. As it remains right now, we’ve talked internally about how cool it would be, but we haven’t had official conversations. [The CW chief Mark Pedowitz] is supportive.”
