This is a very important part of the story for a couple reasons. One of those reasons is that we finally meet Boo Radley. He has been brought up many times throughout the story. Another reason this is important is that it brings the story together in different ways. It connects Bob Ewell with the Finch's. Many different parts of the story came together at the end.
