Continuity: In the scene after Tyler contributes to the routine (different levels), Nora offers him a ride, then they dance on the rooftop. Her outfit switches and then switches back even though its supposed to be the same day. (confirmed in commentary).

Continuity: In the scene where all of the dancers are preparing for the showcase dance, Nora walks in with hair that has her usual bounce. When she and Lucy are talking in front of the mirror, her hair is almost completely straight, sporting just a few slight waves. When Tyler approaches her backstage, her hair is extra curly. It has only been a few minutes, and there was not enough time for her to have curled it. This is confirmed in the commentary.
