In Walk Two Moons, Sal changes from being a quiet and reserved girl to a more confident and outgoing person. At the beginning of the novel, Sal is struggling with her parents' divorce and the move to a new town. She feels like an outsider and has difficulty making friends. However, as the novel progresses, Sal begins to open up and share her feelings with others. She also learns to stand up for herself and what she believes in.
For example, when she is confronted by a bully at school, she refuses to back down and instead stands up to him. This shows that she is no longer allowing others to control her or define who she is. Sal's journey of self-discovery and growth is a central theme of the novel and is what makes her such a relatable and compelling character.
