on Helping Writers become Authors:
A story’s Third Act is unique.
We often think of the Third Act in terms of its being climactic—and therefore full of excitement and high stakes. And it often is.
But ultimately the Third Act fulfills a much more symbolic function within a story.
Simply put, it is the proving ground for all the character has learned and accomplished in the Second Act.
Even more than that, it is representative of the human psyche’s deepest levels of integration. It is, in many ways, the Underworld of your entire story.
