“The Flash” has a song in its heart and it’s ready to let it out. After way too much anticipation, the musical crossover between “The Flash” and “Supergirl” is here. Surprisingly though, it’s literally nothing like what anyone was expecting.

If you were looking forward to seeing the Flash (Grant Gustin) and Supergirl (Melissa Benoist) speeding around Central City, chirping a tune while fighting a maniacal metahuman, you’re out of luck. Instead, the crossover is going into meta overdrive mode and we’re kind of fascinated by what’s happening.

Figuring it out can be a bit confusing, though. So bear with us while we sort through all of the photos (there are so many), trailers and episode descriptions to break it down for you.
