In chapter 27, Scout mentions that the first strange thing indirectly involving her father was Bob Ewell acquiring and losing his job from the WPA for laziness. Upon being fired, Bob Ewell blames Atticus for "getting his job."
The second strange incident that occurred took place on a Sunday night at Judge Taylor's home. It is implied that Bob Ewell attempted to sneak into Judge Taylor's home but fled before he could be identified.
The third incident that took place involved Helen Robinson. Bob Ewell began to harass and threaten Helen Robinson on her walk to work. Bob even followed Helen all the way to work one morning "crooning foul words" at her. Mr. Link Deas was forced to defend Helen Robinson and threatened to have Bob arrested for harassing his employee. When Aunt Alexandra insists that Bob Ewell has a running grudge with everyone involved in the case, Atticus demonstrates his tolerant, sympathetic nature by saying,
It might be because he [Bob Ewell] knows in his heart that very few people in Maycomb really believed his and Mayella’s yarns. He thought he’d be a hero, but all he got for his pain was . . . was, okay, we’ll convict this Negro but get back to your dump. He’s had his fling with about everybody now, so he ought to be satisfied. He’ll settle down when the weather changes. (Lee, 255)
In addition to sympathizing with Bob Ewell and attempting to understand his motives for revenge, Atticus also reveals his positive outlook towards all of humanity by believing that Bob Ewell will settle down. Atticus naively has faith that Bob Ewell will get all of the anger out of his system when the weather changes and has hope that he will eventually come to his senses.
