Beverly Hills, 90210

Sheryl, Brandon's old girlfriend from Minneapolis, stays with the Walshes for the weekend. A concerned Cindy asks Jim to have a talk with Brandon. Before he gets around to it, Sheryl spends the night in Brandon's room. Sheryl seems obsessed with wealth and fame, and takes a liking to Dylan and his Porsche. Brandon believes that Dylan is hitting on Sheryl and punches him. Brandon is stunned to learn that he was not the first guy to sleep with Sheryl. Sheryl's mother calls Cindy and reveals that her daughter ran away following a fight with her stepfather. Brenda babysits for her handsome algebra teacher, with "help" from Kelly and Donna. She no longer finds him appealing after watching his wife push him around.

Brandon is getting a C in American History because of the teacher's unreasonable grade curve, in which 80 percent of the students receive C's regardless of their marks. Steve scores an A on every test because he obtains copies of the exams beforehand. Feeling pressure from Jim about his grades, Brandon cheats on a quiz. Andrea is furious, particularly when her grades slip as a result. Brandon is faced with a moral dilemma when Steve offers him a copy of the midterm. Brenda tries to dye her hair blonde in the hopes of impressing Dylan, but winds up looking like a clown. Dylan flirts with Brenda and takes her to a stylist to repair the damage.

Brenda is mesmerized by Kelly's hip and glamorous mother Jackie, a former model. Kelly insists that her mother is not all that she appears to be. Jackie is a recovering addict, and begins hitting the bottle again after her boyfriend dumps her. Cindy is hurt when Brenda initially fails to ask her to be in a mother-daughter fashion show. They eventually agree to appear, and are joined by Andrea, who draws raves. Jackie attempts to emcee the show while high on cocaine. She becomes disoriented and disrupts the show with a rambling tirade. Kelly convinces her to check into rehab. Kelly gains new respect for David when he gives her the fashion show tape to save Jackie from embarrassment. Jim becomes addicted to his new keyboard.

David becomes the new campus DJ after Steve chokes in his tryout.

Brenda becomes a trainee for a teen crisis hotline, although Andrea questions her devotion. Brenda violates the rules by taking a call after hours. The caller is a date rape victim, who suffers the same fate on three consecutive nights. Brenda is desperate to learn the girl's identity and help her. Brandon believes that a masseuse has a romantic interest in him. He also dodges a freshman admirer, who similarly gives the cold shoulder to Scott.

Brenda and Dylan continue their flirtation, and she accidentally catches him in the shower. They go out alone when Brandon has to stay home sick. Dylan loses his cool after a confrontation with his father. Brenda consoles him, and they end up kissing. Jim objects to the relationship because Dylan's father is considered ruthless and crooked. Brenda is prepared to go all the way, and is crushed when Dylan stands her up. He later explains that he had to move because his father skipped the country to avoid an indictment. Steve tries to make a pass at the speaker for a sex education assembly. She reveals that she has AIDS. Her speech prompts Brenda to slow things down with Dylan.

Brenda goads Brandon into taking her to a party at Donna's house. He voices his objections to alcohol, but Steve spikes his drink. He decides to go along with it so that he won't appear ""uncool."" Kelly gets drunk and sleeps with Steve. Cindy catches Brenda with alcohol on her breath, but Brandon gets by unscathed. Jim and Cindy attend a weekend retreat, where they are forced to spend all their time with an overly friendly couple. Brenda convinces Brandon to throw a party, but they agree not to drink. Word of the party spreads, and it quickly gets out of hand. Brandon drinks heavily and kisses a stunned Andrea. Kelly dances with the lovestruck David to avoid Steve's advances.

Brenda and Kelly win skydiving lessons from a radio contest.

Brenda invites Kelly, Donna and Andrea over for a "night of female bonding." They are having a good time until Kelly's friend Amanda shows up. She insults everyone and decides to turn the girls against each other. As part of a "game" about secrets, Amanda bullies Kelly into describing her first sexual encounter, in which she was humiliated by the football captain. After Brenda recalls stealing a Minnesota friend's boyfriend, Kelly admits that she tried to hit on Dylan. The girls eventually make up, and Brenda and Kelly vow to never let a man come between them. Amanda's behavior is attributed to a diet pill addiction. The girls catch David and Scott lurking outside the window and taking pictures of them. Brandon and Steve are denied entry to a club, but hook up with two girls. They steal Steve's Corvette, but he doesn't press charges (and pays their traffic ticket) because he foolishly thinks that he and Brandon still have a chance with them.

The Walshes agree to let their maid's extremely intelligent "niece," Karla, use their address to enroll at West Beverly. Brandon falls hard for her, but doesn't understand why everyone seems opposed to their relationship.

The boy reveals that his family is homeless.

Brandon is rollerblading in the park while the television show Keep It Together is filming an episode. The producers seek him out as an emergency replacement for one of the extras. He hits it off with the star, Lydia Leeds, and is considered for a recurring role. However, Lydia is only using him to make her leading man/boyfriend jealous so that he will end his holdout. Brenda fills in for Brandon at the Peach Pit. She is in over her head until she adopts the persona of Laverne, a sassy, gum-chomping waitress. She quickly charms all of the customers with her wisecracks and lip-synch routines.

Andrea persuades Brandon to run for class president. Kelly seizes control of the campaign and encourages Brandon to capitalize on his looks and image.

Everyone but Dylan is driven into a frenzy by the upcoming SATs. A completely panicked Andrea seeks help from Steve, who attended an expensive SAT prep course. During their study session, they end up kissing, and avoid each other for days. Kelly reads an article about breast health, so the girls take time out from studying for a self-exam. Brenda discovers a lump in her breast and must undergo a biopsy. Cindy and Brenda are haunted by memories of Cindy's sister Sheila, who died of breast cancer. Brandon cannot concentrate during his SAT, so he leaves during the exam to go to the hospital. (He and Brenda are to take a make-up test at a later date.) Brenda is relieved when she receives a clean bill of health.

Brandon gets assigned to a story on West Beverly's star tennis player, Richard Azarian, who is initially resistant but finally allows Brandon to interview him. He finds a screenplay that Richard wrote, and it's autobiographical contents lead Brandon to worry that the tennis star may be considering patricide. Meanwhile, the gang learn their SAT scores, and Donna's low scores convince her that hanging out with the school's loser quotient is the only future she has.

A dog follows Brenda home from a jog. She tries desperately to find the animal a home so that she won't have to take it to a shelter. Brandon and Steve must take over Jim's little league team after he injures his back during infield practice. Brandon is disgusted with the whole experience, particularly the undue influence of the league president (father of the star pitcher) and the players' attitudes. He arranges a practice game with Nat's team of underprivileged kids, where one of his players taunts the hapless second baseman. Brandon stomps off when Steve won't let him remove the boy from the lineup. He stays with the team out of loyalty to his father, but also helps Nat's squad.

Andrea wants to sleep with Brandon before he leaves, and he agrees. Their rendezvous is cancelled when Kelly organizes a going-away party at the Peach Pit. Jim, swamped at his new job and touched by the outpouring of affection by his children's friends, decides to turn down the promotion. Brenda tells Dylan that she may be pregnant.
