Final answer:
Scout diffuses a tense situation by reminding Mr. Cunningham of his humanity and connection to her and his son, which aligns with the novel's theme of overcoming prejudice through personal relationships.
Step-by-step explanation:
In Harper Lee's To Kill a Mockingbird, Scout tries to accomplish a resolution to a dangerous situation when she speaks to Mr. Cunningham. During this tense moment outside the jailhouse, where Atticus is protecting Tom Robinson, Scout's innocence and direct approach resonate with Mr. Cunningham's sense of decency. She mentions Walter, Mr. Cunningham's son, and their shared experiences, thereby bringing his own humanity and role as a father into the equation. This move on Scout's part defuses the potentially violent scenario by reminding the mob of their individual identities and responsibilities, leading Mr. Cunningham to disperse the crowd. Scout's actions illustrate a powerful theme in the novel: that personal connections and an appeal to common virtues can overcome prejudice and violence.
