Answer:
One word to describe this chapter would be revenge/ harassment (one of these if you wanna choose) because Bob Ewell begins to harass different people in the town because he is mad that Atticus took the job that Ewell wanted so this chapter is all about how Ewell takes his anger out on other people who were connected with the case before and holds a grudge against them
Step-by-step explanation:
One part of the chapter that surprised me was when Bob Ewell attacks Jem and Scout on their way home in the dark. This chapter shocked me because attacking children is a horrible crime with a huge price to pay and for him willing to do that is crazy. (but in the end Boo kills Ewell) I hope this is still helpful.
