Here's why this action is significant:
* Breaking the fear: Jem's decision to retrieve his pants despite the fear associated with the Radley house shows a significant shift in his perspective. It demonstrates that he is no longer completely controlled by the town's gossip and prejudices.
* Challenging the status quo: Jem's act of going back to the Radley house is a direct challenge to the established norms of their community. He refuses to be bound by the fear and ignorance surrounding Boo Radley.
* Transitioning into adulthood: Jem's action signifies a step towards maturity. He is beginning to question the established order and develop his own independent thinking.
This act of defiance ultimately sets in motion a chain of events that will eventually lead to a deeper understanding of Boo Radley and the complexities of their community.
