Bruce Wayne: [Bruce Wayne finds a letter behind the locked door written by his father, reading] Dear Bruce, these last weeks I begin to feel very mortal, which prompts this note to you. Perhaps I'm being paranoid. I hope so. In any case, if you're reading this, then I'm dead, and you figured out that the entry code is... 'Bruce'. I'm sorry I had to hide this part of my life from you, because this place only exists because of you. Becoming a father made me want to be a better man, and I started asking hard questions about the family business. So here we are.
Bruce Wayne: [Bruce's voice begins to crack with tears, reading] As I write this, you're 12 and a fine, good-hearted boy. So I'm sure you'll be a fine, good-hearted man. But that's all I know. I don't know what happened to me or your mother, or how life has turned out for you. I don't even know how old you are. So I'll resist giving you much fatherly advice. Only this: You can't have both happiness and the truth.
Bruce Wayne: [the camera shows Officer Gordon loading his gun] You have to choose. I beg of you, my son, please choose happiness.
Bruce Wayne: [the camera shows Bruce Wayne hold his head up to Alfred] Unless... unless you feel a calling. A true calling.
