It is in chapter 11 that Jem finally snaps and takes out all of his anger and aggression at Mrs. Dubose on her flowers, destroying them with Scout's new baton. As punishment, Atticus sends Jem to apologize. Mrs. Dubose asks Jem to come read to her every day for a month, which Atticus agrees he will do.
A potential problem with the point of view here could include that because the story is told from Scout's perspective, the details of Jem visiting Mrs. Dubose would have either been left out, or retold from what Jem passed along to Scout. Instead, Harper Lee includes Scout in the action by having her go with Jem to read. In this way, Scout experiences first hand the fear the Jem feels, but also witnesses Mrs. Dubose conquer her morphine addiction without even knowing it.
