Beverly Hills, 90210 - Season 7 Episode 28 All That Jazz

Brandon has to take care of Kelly and Valerie, who are both laid up with the flu. The girls discuss the reasons for their feud, which supposedly dates back to a time when Kelly interrupted a make-out session between Valerie and Brandon. Val blames Kelly for costing her the love of her life, while Kelly insists that she gave Brandon her blessing to date Valerie. Valerie is contacted by Derek Driscoll, a representative from Mr. Taylor's firm. Val tells Brandon that Kelly is hiding the fact that she was accepted to Columbia's graduate school. Kelly declares that she is not leaving town, and decides that Brandon should throw Val out of the house. David convinces Donna to join him at his business meeting in New Orleans, even though she has a class presentation the next day. David thinks that he will score, but gets no further than usual. They oversleep, causing Donna to miss her presentation. Samantha ignores Chancellor Arnold during an evening honoring her sitcom, and eventually dumps him.
