On the first day of school, Dylan makes a date with Emily Valentine, a new student who plays guitar and rides a motorcycle. She also makes a date with Brandon, and all of the guys seem quite taken with her. Emily offers to help Brenda, Kelly and Donna put together an act for the hello assembly. Dylan and Emily park at a spot overlooking the bluff and share a kiss. Brandon takes her to the same place the next night, and they also kiss. Brenda becomes extremely jealous and possessive after learning of Emily's involvement with Dylan. She accuses her of being a tramp, and treats her terribly at a barbecue at the Walsh house. Brenda apologizes to Emily and pleads with her to stay in the act, so that they have someone with talent. Brenda realizes that she still loves Dylan, and they get back together. Scott returns from his summer vacation in Oklahoma sporting a cowboy hat, with sudden interests in country music, fireworks and guns. David freaks out and decides to distance himself from Scott

Brenda, Dylan, Steve, Donna and Kelly attend a Halloween party. Donna dresses as a mermaid; but her fins inhibit dancing, walking, and trips to the bathroom. Kelly's seductive costume catches the eye of a college student. She goes upstairs to talk with him, then becomes uncomfortable. The guy accuses her of leading him on and tries to rape her. Brenda and Donna enter in the nick of time, and Steve punches out the guy. Brandon stays home to hand out candy (actually raisins), but Emily comes to the door with her niece and nephew. Brandon joins them for trick-or-treating, but he and Emily get caught up in their conversation and temporarily lose the kids. David blows off the party and finds Scott hiding out in the bushes. They reminisce about the old days while waiting for an egg fight that never materializes.

Mrs. Scanlon organizes a surprise party for Scott's birthday, and pushes David to round up the guests. Donna is the only person who wants to attend. Kelly, Steve, Brenda, Brandon and Emily reluctantly come to the party, but act like jerks and refuse to participate in the activities. David tries to save the party by getting everyone to dance, but Brandon and Emily sneak upstairs to make out in the bedroom of Scott's little brother. Mrs. Scanlon throws them out, and the others act really indignant and walk out on the party. Scott goes to his father's den to get matches for the cake, and finds a gun in a locked desk drawer.

David's friends and teachers annoy him by constantly asking about his well-being, while Mrs. Scanlon keeps trying to give him Scott's belongings. Donna takes offense when David c
