The upcoming CW crossover between “The Flash” and “Supergirl” is possibly the most anticipated event of the year because on top of being a crossover, it will also be a musical.

As exciting as it is to hear that these superhero shows will be taking advantage of their ridiculously multi-talented cast, we have been wondering just how the episode will manage to incorporate singing and dancing into the mix without seeming absurd.

In an interview with Collider, “Supergirl” showrunner Andrew Kreisberg revealed that it may just be all in their heads.

“It’s funny, we have villains that can split the earth in half. We have villains that can run at the speed of light,” he says. “What’s so crazy about a villain that can make you think your friends are singing and dancing in front of you?”

The news that a new villain will be coming to make National City a whole lot more musical is a great excuse to work some song and dance in there.

The fact that this villain can compel people to perform — or at least compel the hallucination that they’re performing — even harkens back to the musical episode of “Buffy,” when the vampire slayer and her friends were forced to sing and dance thanks to a demon’s evil influence.

We’re most interested to hear if this new villain will zero in on one of our heroes in particular when he or she arrives. As hilarious as it is to imagine everyone falling under the same musical sway, it’s almost funnier to imagine Kara (Melissa Benoist) or Barry (Grant Gustin) as the only ones hearing/seeing the musical production happening in their heads.

As for who this villain might be, we’re taking a close look at the Music Meister. Originally a Batman villain, the Music Meister works in much the same way that “Buffy’s” musical demon, Sweet, does. A villain who forces his victims to dance to whichever beat he chooses, the Music Meister uses the power of hypnosis to compel these impromptu musicals.

Hypnosis sounds just about right for a hallucination-type of episode, don’t you think?

“Supergirl” returns Oct. 10th at 8 p.m. ET/PT on the CW.
