This is the nature of the Main Character’s struggle in a story. He has either built up an understanding of how to try and solve problems that no longer fits, or he has built up an understanding of what causes problems that is no longer correct. The backstory builds upon one of these scenarios. A context is established that creates one kind of problem solving regarding a specific problem. The story begins when the context changes and the problem solving technique is no longer appropriate. The question then becomes whether the Main Character should Change to conform to the new situation or remain Steadfast until things get back to “normal.”
