As flawed as Nathan may be, he still gives Polly and Amari valuable information about Fort Mose and what they’ll find there. By giving them this information, he’s able to help them gain a bit more power—the knowledge of what’s ahead is its own kind of power. His sympathetic behavior toward Amari suggests that he may be more genuinely interested in helping them than he previously seemed. By doing this, he can resist the system of slavery—though he’ll need to rethink his controlling behavior if he really wants to make a difference on a bigger scale.
