a complete paradigm shift
Every Main Character represents one special character element. This element is either the cause of the story's problem or its solution. The Main Character cannot be sure which it represents since it is too close to home. Near the climax of the story, the Main Character must demonstrate whether he is going to stick with his original approach in the belief that it is the solution or jump to the opposite trait in the belief he has been wrong. In "Leap of Faith" stories this will occur during a "moment of truth." In "Non-Leap of Faith" stories this will occur over the course of the story and be assessed for Change or Steadfastness at the end of the story. When a Main Character abandons his original story-long approach for its counterpart, he is said to Change.
