Just as Aunt Alexandra gossips about the different families of the area, she apparently gossips inside her family. While Francis and Scout eat their Christmas dinner at Finch's landing, he tells her that his grandmother [Alexandra] is going to teach him to cook. Scout giggles and remarks that she would not want Dill waiting on her; further, she reveals that she is going to marry Dill.
"You mean that little runt Grandma say stays with Miss Rachel every summer?...Grandma says he hasn't got a home...he just gets passed around from relative to relative...."
Francis also reveals that Aunt Alexandra disapproves of Atticus's allowing Scout to "run around with stray dogs[Dill],....and he adds that he guesses it also is not her fault that "Uncle Atticus is a "n****r-lover besides." And, he adds, his grandmother says that they will "never be able to walk the streets of Maycomb" because Atticus is ruining the family.
These cruel remarks of Francis that are meant to insult her cause Scout to attack her cousin in defense of her father and her friend Dill. Of course, Scout also sees Aunt Alexandra in a new light.
