October Novel Prep Challenge

For me, my favorite themes from this year were in Pride and Prejudice. A few reasons why.

First, the resolution resolves itself specifically because of the theme.

Second, the main characters make mistakes related to the theme, and they have to fix their mistakes in such ways that resolve themselves within the confines of the theme.

I guess my question is this (if I can piggy back): What are some ways you can resolve your themes, all while using the potential plot and characters as a framework for such things? And. Are people taking inspiration from the questions above?
