Plot hole: In this episode all the students say Hollywood Arts has never had a prom before. But in the first episode, 'Pilot', Rex says to Cat after she runs out to tell Tori, Robbie, Andre and him that Sikowitz wants them to come back into the classroom, "Just like you wanted a date to the prom last year."
Plot hole: When Cat, Beck, Robbie, Jade and Andre are telling Tori about why they faked the Ping Pong team, it shows a flash back of two years ago when Tori hadn't started at Hollywood Arts yet. But in the background of the hall when they are asking for Sikowitz to help them, Tori's locker is there - how can her locker be there when she hasn't even started at the school yet?

Plot hole: Some episodes act as though Drake and Josh was real and some act as if it is a T.V. show. In the episode with the new principal, Helen from Drake and Josh is the same character as she was in Drake and Josh and becomes Hollywood Arts' new principal. But, in the episode when Trina's play-scene was sabotaged, Cat and Tori refer to Drake and Josh as a television show.
