Led by the Music Meister, Cisco, Winn, and Malcolm Merlyn teamed up for a group song and dance number. Barry and Kara tried their hardest to resist, but no one could turn their back on such a fun number.
Kara and Barry weren't the only ones Music Meister wanted to "help". After his time in the Speed Force, Wally needed an extra push to get Kid Flash back in the game. He found it when it came to stopping the baddie.
Back in the real world, Team Flash and Team Supergirl were tracking the Music Meister. Cisco and Wally prepared to go after him, but hesitated to bring J'onn. He transformed to his true self in order to make his case.
It doesn't take long for Barry and Kara to recognize other familiar faces. But their friends have different names and personalities in this movie. Winn's a piano player, and Cisco's a waiter with much bigger dreams.
Kara's been in the musical world longer than Barry. And it seems like she was acclimating fairly well. Right up until she spotted Barry watching her sing, and remembered things were super weird.
After Music Meister puts a whammy on Barry, he finds himself in a nightclub. On stage, Kara is showing off her musical talents. Barry watches in shock, and eventually, awe.
Cisco [to Wally]: We win and we lose as a team. I'm coming with you. J'onn: Me too. Cisco: Look, J'onn. I respect this whole special agent situation you've got going on. But this problem right here needs someone with... J'onn: [transforms to his Martian form] Cisco: ...green skin and a sick ass cape. J'onn: Call me the Martian Manhunter. Mon-El: I think you'll find that J'onn's a lot more than just a pretty face.
Barry [singing]: I'm your super friend. Your super friend. I'll be there in the nick of time if you're ever in a spot. Kara [singing]: And if not there in time, you can just go back in time and give it another shot! Barry: I'm actually not supposed to do that anymore.
