What does Scout reveal about her relationship with Atticus in Chapter Nine?

In Chapter Nine of To Kill A Mockingbird, we see a little of what Scout and Jem will have to face because of Atticus's defense of Tom Robinson. At the beginning of the chapter, we learn that Scout has just accosted Cecil Jacobs, who essentially repeated on the playground what has obviously been going around town--the fact that Atticus was defending a black man accused of raping a white woman. Later, at the Finch family Christmas celebration, Scout punches her cousin Francis, splitting his lip, over similar taunting. What this tells us about Scout's relationship with her father is that she is deeply troubled by the accusations going around town. She is proud of Atticus, and though she does not at that point really understand the particulars or the racial dynamics of the case, she will not tolerate those who speak ill of her father. Later, as Atticus speaks to his brother, Jack, (with Scout eavesdropping) he makes it clear that he is very worried about this side of Scout's character. "Scout's got to keep her head and learn soon, with what's in store for her these next few months," he says (90).
