(Laura sings the "Diva Dance" from the Fifth Element youtube)

 You just couldn't let me go could you? This is what happens when an unstoppable force meets an immovable object. You truly are incorruptible aren't you? You won't kill me out of some misplaced sense of self righteousness. And I won't kill you because you're just too much fun. I think you and I are destined to do this forever. You might even share a cell with me. This city is going to be doubling up its rates from people looking their minds. They'll believe in good until there's none left. Until they get a good look at the real Harvey Dent. And see all the good things he's done. You didn't think I would risk losing the battle for Goyltham City in a fist fight with you? So you meet an ace in the hole. Mine's Harvey. I took his wife and threw her into the hole as well. It wasn't hard. As you all know, madness, is like gravity. All it takes is a little push.
