I've been working with Character Build elements and thinking of ways to achieve the effects observed in real movies. There's a moment in Blast From the Past where the MC probes the IC for info. She reveals a self-evaluation about why relationships haven't worked out. This made me think of increasing the variety of unique moments by cross quad interaction. The MC interacts with a Motivation element while the IC interacts with an Evaluation element.
I also wondered what effect revealing at least one quad element of the MC before revealing the IC elements in detail. What if in Act One you revealed the MC quad elements early on? This bonds us with the MC first, so that the IC quad elements would feel more like revelations over the course of the movie.
With the exception of the problem/solution quads (one per throughline), the order in which you explore the other elements and levels of elements (characteristics) falls into the area of storytelling, for all intents and purposes.
Also, make sure you do not confuse the exploration of the SUBJECTIVE CHARACTERS (MC & IC) for those of the OBJECTIVE CHARACTERS (those in the Overall Story throughline). Those are different contexts and their explorations are throughline specific.
