In this chapter Atticus shows how patient he is as a father. When Scout tries to get out of school, he looks at her with "amusement in his eyes." He also shows that he is a good and decent human being who does what is morally right, even if it is not accepted by most in the community. Speaking about Tom's slight chance at winning this case he says, "Simply because we were licked a hundred years before we started is no reason for us not to try to win." Atticus then shows his concern for Scout's behavior, but also his cunningness when he speaks to Jack, but says it so Scout can hear it, too.
Scout is very aggressive. She attacks Cecil for calling her father an n-lover. Then she paid a nickel so she could rub her head against someone who had ringworm. She did that so she could miss school. However, after her talk with Atticus, Scout held her fists down when Cecil teased her again. She did have some restraint after all. When she met up with her brat of a cousin, though, she socked him a good one. That was because the information was really coming from Atticus' sister, Aunt Alexandra. The way he said it, too, makes the reader want to sock him one.
Jem isn't in any of the dialogue or action in this chapter.
