With a Change Main Character, he will either contain the Problem or Solution Element. With a Steadfast Main Character, he will either contain the Symptom or the Response Element.

Why would a Change Main Character contain the problem or solution? In a sense, the inequity of the story is not just in the Main Character or in their environment, but exists between the two. It grows from an imbalance in the distribution of Elements. When a Main Character solves a problem by changing, he restores balance either by taking an Element from himself and placing it back in the environment where it belongs, or by grabbing an Element out of the environment and putting it within himself where needed. If he must give up an Element, he contains the solution to the problem. If he must receive an Element, he contains the problem. Either way, the Main Character must change his internal make-up--his very nature.
