The entire novel explores this feeling of duality in Junior. He has his reservation life, and then he has his Reardan life. Rowdy is his best friend when he lives on the reservation, but when he decides to attend the white school Rowdy calls him a traitor and vows never to speak to him again. Junior feels like an outcast at the reservation because people call him an apple, white on the inside and red on the outside. He feels like an outcast at Reardan, too, where the only other Native American present is the mascot. Reardan and the reservation are two different worlds with different sets of rules, so Junior tries to fit into each world by acting accordingly, which makes him feel like two diferent people.
