How do Hirams relationships change with his father and grappa over the course

By the end of the novel, Hiram understands his father's apprehensions over grandfather. Hiram sees his grandfather for what he is: a bigot and a murderer. This is disheartening for Hiram, but it brings him closer to the truth about the American South as well as the horrible treatment of African Americans. I think Hiram appreciates his father much more by the end of the story and rejects his grandfather.
