Lastly, Arthur, or Boo Radley goes through some significant changes throughout the story. He begins to develop abilities of sharing feelings with the children, which causes him to better understand the children and world around him. This leads to Boo coming out of his shell and treating people with kindness. He goes from someone who never leaves his house to the person who saves the children from Bob Ewell. At first, Arthur never leaves his house and he’s completely isolated from society. As the story progresses, he slowly interacts with the children, and eventually, even comes out of his house to cover up Scout with a blanket. When a house on the children’s street lights on fire, the children stand in front of the Radley residence. Boo Radley, noticing Scout standing in the cold, comes out of his house to cover Scout with a blanket. After the fire, Scout contemplates about where the blanket came from. When Atticus says that she should keep blanket to thank the person, Scout asks “Thank who?” (Lee 96) and Atticus replies, “Boo Radley. You were so busy looking at the fire you didn’t know it when he put the blanket around you” (Lee 96). This quote proves that Boo is transforming from a mysterious being, isolated from the world, into a human who cares about others. He shows empathy by seeing Scout stand in the cold and treats her with care by keeping her warm with a blanket. Ultimately, Boo saves the children from Bob Ewell, a malevolent person who tries to kill Scout and Jem.
