She matures from age 6 to age 9 as the novel progresses but remains naive and idealistic, despite an increased understanding of human nature and racism in her town. At the beginning of the book, Scout is confused by some of the words and names she hears people directing towards her father, such as "nigger-lover". Being only six, Scout does not know how to handle such situations so she tries to resolve her problems by fighting, or by talking to Atticus about what she has heard. By the end of the book, Scout realizes that racism does exist and comes to terms with its presence in her town. Scout also learns how to deal with others, including the Finch family housekeeper, Calpurnia, and her aunt, Alexandra. Scout is the only one of the novel's primary three children (Dill, Jem, and herself) to see and speak to Boo Radley during the course of the novel and realize that he is harmless, despite her initial fear of him. She also stops a mob that is trying to lynch Tom Robinson by talking to the mob leader, Mr. Cunningham, about inviting his son, Walter, over for dinner. Mr. Cunningham then tells the other mob members to get back in their cars and leave them alone. The members listen, and Scout unintentionally saves Tom Robinson's life. She is portrayed by Mary Badham in the film adaption of To Kill a Mockingbird.
