What does A Wooden Leg represent?

A wooden leg is a symbol of Vola’s feelings of guilt. She wears a wooden leg instead of a modern prosthesis to punish herself. She believes she deserves to have to deal with the clunky, heavy leg because she took a life during the war. After Peter makes her agree that she will wear her prosthetic leg instead of the wooden one, they burn the wooden leg in the fire, just like the phoenix and its belongings.
