Jem is still unconscious after the attack, Scout is telling her story.
It dawns on her slowly that Boo
Radley rescued them.
Atticus take a while to realise exactly
what happened during the attack.
At first, he believed that Jem had stabbed Bob
Ewell. (Jem would have to face the
consequences)
Heck knows that it was Boo who killed him.
They decided to put out that it was Mr
Ewell that fell on his own knife, to protect
Boo.
Scout takes Boo home, she never sees him again. Yet, standing outside
the window where Boo always sits, she finally understands what life
must really be like for him.
