I've recently gotten to one of those turning points in my novel, and, I've got to say, I'm very disappointed in my character. She didn't do what I would have done. She didn't do what I wanted her to do--in fact, she did everything wrong.
Which is great.
When you get to the point in your writing where you know, logically, what your characters would do in the situation, especially when it's the opposite of what you'd do, then you know your writing is working, that your characters are clear, and that you've established a strong scene.
Which doesn't mean I still can't disagree with her!
