In both situations, Zits’ and Jimmy’s, the planes held meaning for them. For Zits’ the planes were the first gift he had received in who knows how long. As for Jimmy, piloting is his life. It appears to be his job or an important hobby of his. Zits’ response is reflected in Jimmy’s response because they both just sit by as the planes are crashed. Neither acts out. I think Alexie makes this parallel to draw a connection between Zits and Jimmy beyond a racial issue. The other three characters Zits becomes, have some relation to the Native Americans. Hank and Gus are fighting against the Indians and the little boy is Indian. The closest Jimmy is to some form of racial diversity is his friend Abbad, who ends up betraying Jimmy regardless.
