Lilly, Do You Want to Know a Secret? - S1-E1
Continuity mistake: In the cafeteria, when Oliver joins Miley and Lilly at the table the food and trays change position, particularly the milk carton. Then when Oliver stands up and announces that Lilly has the two tickets, suddenly the apple has changed trays and the juice box and milk carton are lying flat.
Continuity mistake: The broken glass on Nathan's face and arms disappears when he is pouring out the rice, but reappears when he is yelling into the PA system.
