Barry Becomes a Marionette in Special Poster for The Flash/Supergirl’s Musical Episode

Next week on The Flash people sing and dance. No, seriously. And here's some cool art of Barry being manipulated like a marionette. It's a safe bet to assume that this is a metaphor for something that happens in the episode.

Grant Gustin has released a special poster for the upcoming The Flash/Supergirl musical crossover episode. The poster features his character, Barry, being played like a marionette by, who we can only assume, is the Music Meister.

Grant and Melissa Benoist will be reuniting with their Glee costar, Darren Criss for the musical episode. Darren is set to play the villain of the story, The Music Meister.

He will first be introduced in Supergirl’s episode on Monday, March 20, but the action will really not kick off until The Flash’s episode on March 21.
