Most would say... "but emotion is just emotion." But emotions really demand a reaction.
- Example: Heroine searches for the mother that gave her up for adoption, only to find that her mother passed away before she could find her. What is her reaction? Panic? Anger? Loss?
which leads us to revelations...
Revelations are the lessons learned from the emotions and the experiences. They are the warm and fuzzy, or deep and thoughtful moments that move the inner conflict of the story forward and give some measure of satisfaction to the reader.
Okay, so emotions are the catalyst, experiences are the gauge for the reaction and revelations are the outcome of the experience. It's what happens when you find your way through the maze of emotion.
