"Character is too deep to catch in a single storyline. What really moves us - what makes the great stories, and there aren't so many of them - is the inevitability of character. The destiny. All we see is the arc. We'll never penetrate the secrets of the living, let alone the dead. I've spent my whole life trying to understand people, and all I've learned is that the deeper we look, the greater the mystery. At the core, each person is unknowable. Maybe that's the soul? I have to respect that. The mystery, in fact, is what I've loved the most, in people and in stories as well."
