How does Scout's view of her father and Boo mature throughout the novel?
Scout first views her father as old and inept at anything athletic. Atticus wants to avoid games such as football. Also, he suffers from a weak eye, "the Finch curse." It isn't until he kills the rabid dog that the children learn about their father's gift and that he was even called "One Shot Finch" in his day. But in another way Scout has idealized her father; to her he make no mistake in character judgement. Later on though Atticus admits he had underestimated Mr Ewell threats.
As for Boo Radley, Scout's imagination is at first fed by all the neighbourhood stories, and the unkempt yard and run-down house adds to the "spookiness" of the Radley place. The children reinact the "scissors scenario" in which Boo supposedly stabbed his father in the leg. According to rumour, Boo is a drooling, maniac peeping Tom who comes out to eat raw squirrels. Jem makes Scout spit out gum she has found in the Radley tree, affirming that the pecans in their yard are also poisonous. Scout is less fearful than Jem, but she believes the tales concerning Boo and is frightened when she rolls up inside the tire to the Radley door. However, the children get a glimpse of Boo's kindness when they find Jem's pants mended and folded on the fence (Jem doesn't tell Scout about this right away), and later when Boo wraps a blanket around Scout during Aunt Maudie's fire. Scout realises that surely he isn't the monster or the maniac he has been cracked up to be.
