Answer:
Mitchell and Jimmy T. learn to accept themselves and be proud of their racial identities
Explanation:
In the story, Mitchell has always felt inadequate, and as an outsider, and doesn't show strong racial identity, as he feels he's not a good enough indian, due to his heritage. On the other hand, Jimmy T. has been living a lie, telling people he's native american, when in reality he is Hungarian, so he feels like a "phony" for doing this, and distances himself from Mitchell because he thinks Mitchell would be able to uncover his lie. He has lots of family issues and feels ashamed of his heritage and pretends to be an indian to get away from the pain in his real life.
When Mitchell starts interacting with Randolph, he learns he is very proud of his heritage, and that he also has Native American roots, and is encouraged by his family to respect and embrace his roots. This helps Mitchell to gain confidence and respect for his heritage, combined with the fact that he learnt about Jimmy´s deceit and that Jimmy saw him as a racial model. By the end of the story, there's a cathartic moment for both characters, who realize that the most important thing is on the inside, exemplified by Uncle Tommy Fox's quote "Whoever you are is real enough. Underneath our skins, everyone’s blood is red"
