Wiggins is not sure he can improve Jefferson's life in the short time before Jefferson is executed. However, Jefferson's godmother, Emma Glenn is a close friend of Grant's aunt. Grant lives with his aunt and persuades Wiggins to visit Jefferson. Ironically, he finds Jefferson just about as reluctant to talk to him as he was to talk to Jefferson.
Grant may feel that speaking to Jefferson is beneath him. Although both men are black. The same prejudice applies as Jefferson is uneducated and Grant is the only educated black man in the community. One gets the sense that Grant feels he better than other blacks just as white people feel they are superior to blacks.
