In season one, Suzie is very gossipy and sometimes mean. Ned begins to develop a crush on her in this season. Also, she is friends with Bitsy Johnson, the main mean girl in season 1 (Missy Meany came in during season 2, replacing Bitsy for the rest of the series). She and Ned are put in charge of decorating the dance in Guide to: Crushes and Dances, and she turns out to be really nice to him, but Suzie starts dating Seth Powers. Suzie has light brown hair in this season, unlike seasons 2-3, when she had darker hair.
In season 2, Suzie seems kinder. Ned receives his first kiss from her in Guide to: The New Semester and Electives, even though she is dating Loomer. She tells him "our love will never be, for now". In Guide to: Asking Someone Out and Recycling, Ned tries to get Suzie to ask him out, but she says no because she just broke up with Loomer. In Guide to: Spirit Week and Clothes, Suzie wins Spirit Queen. In Guide to: Double Dating and The Last Day, Ned and Suzie go on a double date. In the episode Guide to: Dismissal and The School Play, Suzie moves into Ned's locker and in the same episode, Suzie plays Juliet Capulet in the school play based on Romeo and Juliet. In Guide to: Money and Parties, Ned takes Missy to a party but Suzie arrives, so Ned thinks up a way to get Missy kicked out so he can be with Suzie. Moze and Suzie kindle a friendship in which they are very competitive, bringing out the best in each other. She appears to have stopped being friends with Bitsy. She begins dating Loomer, who ironically had been instructed by Ned on how to attract women to ask Moze on a date. When she finds out that Loomer cheated on her with Missy Meany, she breaks up with him. Though Ned tries to build a relationship with her, she still does not go out with him. Later in season 2, she develops a crush on Ned. This crush remains, even after he accidentally kisses Moze at a school dance.
In season 3, her relationship with Ned begins to grow stronger, and they begin dating in the episode Guide to: Popularity and Stressin' Out. Suzie informs Ned at the end of Guide to: Hallways and Friends Moving that she is moving out of state to be closer to her dad. Despite the distance, the two still talk on the phone. She returns at the end of Guide to: Tests and When You Like Someone Who Is Going Out With Someone Else, though Ned and Moze realized that they like each other. At the end of the series, she begins to date a changed Loomer.
