When people hear the word relationship, most think of a romantic and/or sexual relationship, but it’s important to recognize that this represents a small fraction of the relationships that influence every character. In the context of this post, a relationship is any time that one character applies opinions or expectations onto another, whether the other person knows it or not.
Stories frequently show how characters grow to become heroes, or demonstrate and prove that a character is a hero. A hero represents an ideal, the ability to set aside selfish desires and work for the sake of others, sometimes sacrificing personal goals in the process. In a word, altruism. Heroes live by a moral code, with the will to endure, resist temptation, and help others.
