Identity between two worlds
Junior is Native at Reardan and a traitor at Wellpinit. He spends the book trying to figure out who he is when every community has a different answer. The resolution isn't that he picks one side; it's that he stops believing he has to.
Poverty as a trap
The reservation's poverty isn't just sad background. It kills people, limits choices, and crushes hope over generations. Junior sees this clearly, which is exactly why leaving feels both necessary and guilty.
Hope vs. surrender
Most adults Junior knows on the reservation gave up their dreams. Mr. P tells Junior directly that the school trained students to give up. Junior's whole arc is about refusing that training, even when it costs him.
Grief and survival
Junior loses multiple people he loves in a single year. The book doesn't give him a clean recovery arc. He grieves and keeps going, which the book treats as a real form of courage.
Humor as resistance
Junior uses jokes and cartoons to survive situations that would break someone who took everything straight. His humor isn't avoidance; it's a way of staying present and sane in a life that keeps delivering bad news.
