Because he's the hero Gotham deserves, but not the one it needs right now...and so we'll hunt him, because he can take it. Because he's not a hero. He's a silent guardian, a watchful protector...a dark knight.
I had a vision, of a world without Batman. The mob ground out a little profit and the police tried to shut them down, one block at a time. And it was so... boring. I've had a change of heart. I don't want Mr.Reese spoiling everything, but why should I have all the fun? Let's give someone else a chance. If Coleman Reese isn't dead in sixty minutes then I blow up a hospital.
