Steadfast Character {Character Appreciation} • the Subjective Character who ultimately retains his essential nature from the beginning of the story to the end of story • Every Subjective Character (both the Main and Obstacle Character) represents one special character element. This element is either the cause of the story’s problem or its solution. The Subjective Character cannot be sure which he represents since it is too close to home. Near the climax of the story, each Subjective Character must demonstrate whether he has stuck with his approach in the belief that it is the solution or jumped to the opposite trait in the belief that he is the cause of the problem. There will only be one Steadfast Character in every story, however when a Subjective Character decides to stick with his story-long approach, he is said to Remain Steadfast.
