Cisco seems a little suspicious about the alien arrival. Or maybe he's just wondering why Supergirl's unconscious and who the strangers are.

Knowing Cisco, he's probably got a lot of questions for the prince. Mainly, what happened?!

Well, that didn't take long. Somehow the Music Meister managed to place Barry under the same spell as Kara. We can't blame Mon-El for looking worried.

Iris and Mon-El keep a close watch over their loved ones. Can Team Flash find a way to bring them back?

10. Play that tune, Winn! - The Flash Season 3 Episode 17
Has another one of Supergirl's friends fallen into the Music Meister's clutches? It looks like Winn's being forced to play the piano. But is it really him or a doppelganger in the fantasy world?
11. Performance Notes - The Flash Season 3 Episode 17
Everyone's a critic these days. The Flash and Supergirl rehearse a new song after a costume change. Or, the Music Meister is threatening to kill them both. Maybe a combination of the two.
12. Backup arrives! - The Flash Season 3 Episode 17
Of course Iris, Joe, and Professor Stein are likely there to perform rather than save the superheroes from their musical prison. It's hard not to love the stylish looks of this villainous world.
13. Five, six, seven, eight... - The Flash Season 3 Episode 17
We always knew Winn and Cisco would be the greatest of friends. Apparently, the Music Meister thinks so, too.
14. Malcolm, too?! - The Flash Season 3 Episode 17
We never know where and when the Magician will appear on the scene. Did he take a break from chasing legends to do a quick song and dance number?

Cisco's belting out a tune in the alternate world. We know Music Meister is the villain, but it's hard to fault his good taste!

Maybe a better question would be, does she want to? We know alternate realities are not always happy places for our favorite couple.

Who knew a duet between Professor Stein and Detective West was what we were all missing in life?!
18. Study the script! - The Flash Season 3 Episode 17
The Music Meister makes it clear the only way Barry and Kara can survive is by following the script.
