This watch is the out best find yet!
Boo Radley. You were so busy looking at the fire you didn’t know it when he put the blanket around you.
Boo puts blanket on Scout
When Jem, Scout, and Dill were running away from Nathan Radley, Jem got his pants stuck on a fence and had to leave them there. He later found them sewn up by the fence. This is one of the few moments where Boo Radley's true character is shown. He goes out of his way to get Jem's pants, sew them up, and put them back outside for him. This shows that Boo Radley is really not a bad person.
Boo leaves a pocket watch for Jem and Scout. This again shows that Boo is a really nice person. He had also left other gifts in the days before for Jem and Scout. This is another instance where Boo is shown as a kind and generous person.
During the house fire, Boo Radley put a blanket on Scout without her noticing. This is the third time in the book that Boo proves he is not like what the rumors say he is like. This action shows he is a very kind person that cares for others.
