After enjoying a successful summer in London, Brenda decides to stay in England and pursue her stage career. With her room vacant, the Walsh family agrees to take in Valerie Malone, the college-age daughter of a family friend who has committed suicide. Valerie appears charming and likable, but she is actually cynical and manipulative and plots to get involved with Steve for his money. Donna returns from her summer stay in Texas and claims that she's over with David, who's doing a video for his film class, with a little help from Nat, about his summer of working with Babyface, dating and being dumped by both a girlfriend and the tour, and having some good luck near the end of the season. But that evening, Donna has an emotional meltdown when she runs into David at a nightclub. Meanwhile, Dylan breezes back into town after a binge-filled summer in Mexico while he tries to process the loss of his entire fortune, and Kelly and Brandon take their relationship public. Also, Jesse and Andrea take their premature baby daughter, Hannah, home from the hospital after Andrea details how her maternal instinct was the reason Hannah is still alive.
