Scout's most courageous act in To Kill a Mockingbird comes in Chapter 15 when she and Jem arrive at the jail while Atticus is confronting the lynch mob. Scout senses that something is wrong, but she doesn't really understand the implications of the gathering until the next day. Her innocent banter with Walter Cunningham shames him, and he directs the other men to "Let's get going."
Scout shows courage when she stands up for Walter Cunningham Jr. on her first day of school. She tries to explain why Walter has no lunch money, but she instead gets in trouble with Miss Caroline. She shows courage when she accompanies Jem and Scout into the Radley's back yard, and she shows her speed when she runs back to safety after Boo's shadow appears on the porch. She shows courage (or is it her foolish hot temper?) each and every time she fights a boy in the schoolyard, and her bravery is evident when she runs to the sound of Jem's screams during the attack by Bob Ewell.
