"Alfred: Ever since you were a child, I have seen in you such luminosity of spirit... It was truly almost visible -- some indefinable and yet unmistakable fire at the very core of your being that allowed you to survive and thrive where so many others... [long pause] But now that very spark seems to have vanished from you, Master Dick, as if it had never lit your heart. I do not know why and I do not know how to help you. But I fear that without it, this life you and Master Bruce lead could well prove... [whisper] unsurvivable."
