The night after their argument, Sharpay finds out about Amber Lee's true face and seeks comfort in Peyton. After exposing the actress's true face to the world, the agents are forced to cancel the show.
However, just as the performers are about to leave, Peyton shows them a video of Sharpay's secret stage singing to show them what she's truly made of.
