the story as it relates to the relationship and conflict between the Main and Obstacle Characters
The passionate argument of a story is carried by the relationship between the story's Subjective Story Characters namely, the Main and Obstacle Characters. The examination of their internal states and the articulation of the story's passionate argument makes up the Subjective Story Throughline. This is not the view from within the shoes of either the Main or Obstacle Characters, but is rather like an Objective view of their relationship. It is a view of their story together which always sees both of them.
