Bruce Wayne: People need dramatic examples to shake them out of apathy, but I can't do that as Bruce Wayne. As a man of flesh and blood I can be ignored, be destroyed, but as a symbol... as a symbol I can be incorruptible, I can be everlasting.
Alfred Pennyworth: What symbol?
Bruce Wayne: Something elemental, something terrifying.
Alfred Pennyworth: I assume as you're taking on the underworld, this symbol is a persona to protect those you care about from reprisals.
Bruce Wayne: Are you thinking about Rachel?
Alfred Pennyworth: Actually sir, I was thinking 'bout myself.
