How is Ned Buntline an important character in the play, Indians?

Ned Buntline is a writer who chooses Buffalo Bill as the subject of his work. He wants to make Buffalo Bill famous, which the cowboy finds intoxicating. Buntline urges Buffalo Bill toward tall tales and unnatural behavior to improve his stories. Buntline's play Scouts of the Plains is performed at the White House, starring Buffalo Bill and Wild Bill Hickok as themselves. Like Buffalo Bill's Wild West Show, Buntline's play is a sad caricature of the real experience. Buntline is stabbed and killed when Hickok realizes the humiliation Buntline's play is attempting to put him through. Like the American Indians, Buntline dies with Buffalo Bill standing there, doing nothing, unsure of whom to please next.
