How is Arnold's perspective changing? (Free Response) -AntotheGreat

Arnold's perspective is changing. At the start of the year, even though he stuck out like a sore thumb, he felt like a part of his tribe. Now, he doesn't feel like a part of his tribe. In fact, Arnold feels so disconnected from them that he says "these dang Indians"(144), as if he isn't one of them, and doesn't feel proud for his tribe at all when they "won by thirty points"(147), his middle school dream. The people on the rez say that he's a traitor and a white lover, which is becoming true because they exclude him in that way. Because no one on the rez accepts him, he's finding his community in Rearden, with Penelope, Gordy, and Roger, and is leaving the community in Wellpinit behind, which is shifting his views. He has no reason to have any concern for the other people on the rez since none of them are part of his community anymore. With the passing of his grandmother, he feels even more disconnected. 

This chasm between him and the rest of his tribe will probably continue to grow, and Arnold will become integrated into the Rearden community. This will probably result in even more resentment by his neighbors, and quite probably more incidents like the basketball game. 

Will the chasm between Arnold and the rez community continue to grow? Will Arnold become a full-fledged member of the Rearden community? Will Arnold and Rowdy make up?
