An author can use repetition to show the traits of a heroic character to make readers connect with their stories and characters.
Repetition is a resource often used in fiction, for it can emphasize setting, enhance a character trait (it can be used as a punctual catch phrase, for example - which brings familiarity and a more in depth personality), and also draw attention to a minor detail. Repetition can make an idea clearer and more memorable, drive the reader deeper into the events; it is a great rhetoric tool.
