My Desperate Valentine - S2-E16
Other mistake: At the end of the episode Brandon mentions he dropped Emily off with her parents and spoke to them. In season 4 when he goes to look for Emily at her parents' house in San Francisco he asked the woman who answered the door if she was Mrs. Valentine, as if they had never met.
Stand (Up) and Deliver - S1-E17
Character mistake: In one scene Brenda refers to Brandon's political opponent as "Michael Miller" but a few scenes later David refers to the same guy as "Robert." He's referred to as Robert for the remainder of the episode.
Answer: The students were told by the faculty that anyone found to be intoxicated at the Senior Prom would not be allowed to participate in graduation activities. Donna had a little too much champagne at Mel's house and in the limo and got drunk. At the Prom she spent most of the time in the bathroom, being sick. As the gang tried to discreetly usher her to the car, Donna fell and Mrs. Teasly questioned her and realized that she was drunk. "Donna Martin graduates" is what her classmates chanted after a walk-out on their final exams, in protest to the fact that the board was meeting inside to make the final decision of Donna's fate. Big surprise: Donna Martin graduated.
