Brianna is a selfish and aloof girl who Abby dislikes very much. She continuously brags about being rich, acting on TV, her ability to speak French, and more. Brianna was followed around by Bethany until Bethany declared her independence later. In That's The Way The Cookie Crumbles, Abby says that she and Brianna were friends for five minutes until Brianna got into her usual bragging routine and said that her pink sneakers were cooler than Abby, and that she danced with a dinosaur on TV.
