Get your jazz hands ready! On Tuesday, "Supergirl" will cross over into "The Flash" for a special musical crossover. Last year, their mini-crossover event led them to become the "Worlds' Finest"; this year, however, they'll be the "Dynamic Duet" when Darren Criss' Music Meister transports them to a musical dream world, where they must follow his script -- or die.
