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 stops a mob about to lynch Tom Robinson by talking to the mob leader, Mr. Cunningham. She is portrayed by Mary Badham in the film. "Notable quote: "Until I feared I would lose it, I never loved to read. One does not love breathing."" Jeremy Atticus "Jem" Finch is Atticus' son and Scout's older brother by four years. Jem's progression into adult maturity is apparent throughout the course of the novel. He is seen to have a greater understanding of the obstacles thrown their way. Jem explains many things to Scout throughout the novel. Bob Ewell breaks Jem's arm during his assault on the Finch children, subsequently resulting in it being shorter than it had been. He is portrayed by Phillip Alford in the film adaptation of "To Kill a Mockingbird". At the beginning of "Go Set a Watchman", an earlier draft of "To Kill a Mockingbird", Jem has already died of the heart condition which killed their mother. Charles Baker "Dill" Harris is a short, smart boy who visits Maycomb every summer from Meridian, Mississippi, and stays with his Aunt Rachel (Aunt Stephanie in the film). Dill is the best friend of both Jem and Scout, and his goal throughout the novel is to get Boo Radley to come out of his house. The children concoct many plans to lure Boo Radley out of his house for a few summers until Atticus tells them to stop. In chapter 5 of the novel, Dill promises to marry Scout and they become "engaged." One night Dill runs away from his home in Meridian, arriving in Maycomb County where he hides under Scout's bed. When she finds Dill, he tells both Scout and Atticus that he was chained to a wall in his father's basement; later, he confesses he actually ran away because he felt he was being replaced by his stepfather. Before Dill returned to Meridian after the summer, he went swimming with Jem at the Barker's Eddy creek. Scout, unfortunately, was unable to participate, because both boys were swimming naked.
