Final answer:
Williams' honor pays off when the true identity of Grandison is revealed, showing how he used deception to achieve his goal.
Step-by-step explanation:
The story by Chesnutt explores the concept of passing through the character of Grandison. Grandison acts as a submissive slave to his master in order to deceive him and plan his escape with his family. When the true identity of Colville is revealed, it shows that Grandison had been strategically playing a role to achieve his ultimate goal. This demonstrates how Williams' honor pays off later, as it allows Grandison to outwit his oppressors and accomplish his mission.
