Scout's view of Calpurnia changes during the course of the novel. In the early chapters, Scout considers Cal a
... tyrannical presence... Our battles were epic and one-sided. Calpurnia always won, mainly because Atticus always took her side. (Chapter 1)
Scout believes that Cal favors Jem and relentlessly picks on her. But Jem has already learned to stay out of Cal's way (just as he later does when Aunt Alexandra comes to live), and Scout slowly comes to realize that Cal is both a friend and role model.

Scout admires the way in which Cal stands up to Lula when the "troublemaker from way back" tries to block the white children from entering her "nigger church." The children's visit to the First Missionary church is a tremendous learning experience for both Jem and Scout, and after Cal explains about "puttin' on airs to beat Moses" is not "ladylike," Scout decides she wants to visit Cal's home in the Quarters to learn even more about her other life.

Scout sees what most others did not: that Tom is innocent and that the white Ewells are liars.
