Things start unraveling? We're learning about story weaving. Is unraveling part of the process?
What happens on this descent? How do these parts weave in with the rest of the pattern of our story structure? So far we've seen that each piece is logically connected and progressively leads to the next. They're connected in sequences of causality. Cause > effect. In storytelling terms, this is setup and payoff. We set up a cause and later pay if off with the effect of that cause. We may also need to plant extra information so we don't surprise the audience with something out of the blue.
We've set up that the character has ignored the lesson of the story and traveled up the wrong path. In life, whenever we act there are consequences to our actions. We may hurt others feelings or make them mad. Our character probably has done both and now has to face the music. The character might try a last ditch attempt to stop his or her fall but they'll probably use their old defenses and make matters worse, way worse.
The character hasn't learned the lesson, their enemies are stronger and their friends are abandoning them.
