After Nick rescued Kate from an attack at the football game they talk as he drives her home. "I said that because I really did see a monster." I looked at Nick as we turned a corner in the road. "You don't think I'm crazy do you?" I like that quote because it symbolizes the transition in Kate's life. She has turned a corner in her life. She unknowingly has left the path of childish freedom and started down a path of danger and responsibility.
