This prompt is to help you explore creating conflict between characters through dialog. Start with a page or so of dialog from your current manuscript and read through it once. Then set it aside. Think of the characters' situation and identify the conflict. Is the conflict addressed in the dialog? Do the characters discuss the conflict outright, or is the conflict the subtext of the dialog? Consider the dynamic of the characters - is one more dominant than the other? Does one character have the upper hand? What if you were to reverse this somehow?
For this exercise, try re-writing one page of dialog from your current work-in-progress. Think about subtext and how it might be used to create conflict or friction between the two characters. Also, don't use any tags, just write the back and forth dialog and keep it flowing. Write for 15 minutes.
