Throughout the story, readers are able to understand how many of the characters have evolved because of the war. First of all, Norman Bowker is one of the participants of war and his mindset undergoes a severely negative change due to that traumatic experience. Additionally, Mary Anne Bell is another character whose interests and beliefs change drastically as a result of the war.
