JOKER: Rachel Dawes...
BATMAN: What?
JOKER: James Gordon...
BATMAN: ...
JOKER: Lucius Fox... hehehehehe... I may be a joker, but i'm not a idiot. Gordon was watching Falcone. He knew he was going down. Rachel Dawes was the principal lawyer agains him... And your suit, your... Batmobile... they are all old Wayne enterprises projects... I Wonder how Bruce Wayne would react he ke discovers that you are using his toys.
BATMAN: I don't...
JOKER: No, you know. That is your weakness. No one can be the Lone Rider. You NEED help to exist. And when you receive help, you drow other peoples on your storm. When you first look at Gordon or Dawes, you put everyone they love in danger.
BATMAN: You can't.
JOKER: No... I Can. I'm only here because i wanted to talk with you... You know... You changed things... Forever. There is no going back. But see, to them... You're just a Freak... Like me!
BATMAN:...
JOKER: I'm warning you. Gotham has a big importance on the final joke. And if you show up, i'll kill everybody you are associated myself. Face it, Dark Knight... You're in MY hands...
BATMAN: ...
JOKER: Oh... What's the problem, Batsy? Why so serious? HAHAHAHAHAHAHAHA!
