What happens between Francis and Scout and what does Uncle Jack learn?

Francis says that Atticus is a "nigger-lover," and that now Atticus will be the ruination of the family, who won't even be able to walk the streets of Maycomb. Scout patiently awaits her chance, and then punches him squarely in the mouth. Francis screams and everyone comes outside. Francis says Scout called him a "whore-lady" and jumped on him, which Scout does not deny. Uncle Jack tells her not to use that language and pins her when she tries to run away. Scout says that she hates him. Atticus says it's high time they went home.

Back at home, Scout runs to her room to be alone. Uncle Jack comes upstairs to have a talk with her about her language. Scout points out that he doesn't understand children very well, since he never heard her side of the story. Uncle Jack asks her for her side and Scout tells him what Francis said about Atticus. Uncle Jack is very concerned and wants to go talk with Alexandra right away, but Scout pleads with him not to tell Atticus, since she doesn't want him to know that she broke her agreement not to fight anyone over the issue of Tom Robinson's case.
