INTERNAL CHARACTER TRAITS OF JEM FINCH.
We know that Jem still has feelings for his mother during the early chapters of To Kill a Mockingbird. Scout does not remember her mother (she was very young when her mother died of a heart attack), but Jem does.
He remembered her clearly, and sometimes in the middle of a game he would sigh at length and then go off and play by himself behind the car-house. When he was like that, I knew better than to bother him.
Jem has become sort of a mother hen to Scout by the end of the story. He gives her advice, comforts her when necessary, and in Chapter 28, he walks her to and from the Halloween carnival. When the mysterious attacker (Bob Ewell) goes after Scout, Jem fights him off. He succeeds in keeping Bob away until Boo comes to their rescue.
INTERNAL TRAITS OF SCOUT FINCH
Scout's temper gets the best of her often in the early chapters of the novel. She is ready to fight at the drop of a hat, and she is warned by Atticus that he "will wear me out" if she continues. By the end of the novel, Scout has grown three years older and has matured dramatically. She actually entertains lady-like ideals on occasion, and she learns to hold her temper when she is tempted. She is also able to distinguish fantasy (the stories about Boo Radley) from fact (Miss Gates' conflicting statements concerning Maycomb's Negroes and Hitler's treatment of the Jews).
