Alfred: If you're seriously considering going back out there, you should hear the rumors surrounding Bane.
Bruce Wayne: I'm all ears.
Alfred: There is a prison in a more ancient part of the world, a pit where men are thrown to suffer and die. But sometimes a man rises from the darkness. Sometimes the pit sends something back.
Bruce Wayne: Bane.
Alfred: Right. Born and raised in hell on earth.
Bruce Wayne: Born in prison?
Alfred: No one knows why or how he escaped, but they do know that once he did he was trained by Ra's Al Ghul, your mentor.
Bruce Wayne: Bane was a member of The League of Shadows.
Alfred: And then he was excommunicated. And any man who is too extreme for Ra's Al Ghul is not to be trifled with.
