Element

the source of the Influence Character's drive

In every Influence Character there exists some inequity that is driving him. If the Influence Character Changes something in himself in response to the Main Character's Steadfastness, it is this item, his Problem, which he changes by exchanging it for his Solution. If the Influence Character is Steadfast, though, then he holds onto his problem, deepening his resolve to keep the same motivations at the end of the story as he had when he began the story.
