I’d thought that MC and IC were two opposing perspectives (one of which changes at the end) and the RS was them interacting until they get to that point of change. If RS isn’t about that changing perspective, what is it for aside from making sure that the Overall Story has a dynamic pair? If IC is trying to help MC with something, is that actually in the IC throughline, or is it half in IC (“That poor MC needs my help”), half in MC (“I have this problem I need help with”), or if everyone’s concerned with the Future/Obtaining/whatever the help might fall under, should it be in Overall?
I’m not sure I can imagine a relationship without the people and their baggage involved in it.
