I believe that Charity is not only a naive character, but she doesn't know who she really wants to be in life. She is not sure of her aspirations and whether or not North Dormer can actually help her conquer them. Lucius Harney is supposed to highlight the fact that Charity is such a weak character, because he is too. They are both searching for growth in their lives but cannot see outside of their existance to grow from their experiences. Mr. Royall, is very similar to Charity in the fact that he is unsure of his person, but he contrasts Charity in a way to compliment her growth as a person. He allows her space enough to grow but a reinforcement when she may need it. Summer was written to show that relationships do not work out when neither character can grow and change together, and that is why in the end, Charity finds herself with her first suitor, her father character, Mr. Royall.
