At this point in the story, Scout is getting fed up with Jem's antics, and when she stands up to him she's disappointed to see Dill side with him and not her. This leaves Scout isolated from the group as they continue to get into mischief without her, plotting and playing alone in the treehouse and forbidding her to join. She's particularly upset by Dill's behavior, as prior that summer he had asked her to marry him, yet now he seems to have no interest in what she's doing or has to say. Dill and Jem have only grown closer, and in doing so they've pushed Scout out of the group.
