Zach’s slangy expressions of joy (e.g., “Wizard!”) emphasize his extroversion in contrast to Willie’s shyness. Tom lets Willie choose with whom he’ll socialize, which shocks Willie. Willie’s shock implies that his mother did not allow him to make independent choices. Meanwhile, Willie’s terror of the bath indicates that his mother never bathed him, another sign of her neglectful parenting—whereas Tom gently persuades him to do so. Yet again, the novel contrasts Willie’s mother’s abusiveness with Tom’s affectionate, gentle guardianship. It also contrasts Tom’s gentle religiosity (as when Tom tells Willie the creation story rather than simply reading to him from the Bible, which might be too difficult for a young boy) with Willie’s mother’s severe religious dogmatism.
