I love it when characters surprise you, just like real people. When I write a scene I just try to make the characters behave in a way that feels natural to them. Sometimes that means they make a left turn and do something unexpected. Those are always the best scenes in my opinion.
But one thing that's constant is we've always appreciated fans. They put us on the map and they keep us on the map. I always put myself in their position. If I loved someone and had their posters all over my wall and met them and they were rude it would be very hurtful.
