MTV scored an exclusive trailer detailing the role Joker will play in the upcoming Batman: Arkham City. Of course, this epic video is a bit of salt in yesterday's open wound that the PC version of the game is delayed by a month, but that's besides the point. Harley Quinn has something interesting to say to Batman about Joker: "What's wrong with you B-man? You come into Mr. J's home and start smashing it to pieces. Don't you know he's sick?" Joker also remarks that both he and Batman could die that night. What is the Joker's secret? Is his illness from the Titan formula actually fatal? What is this all about? November? We really have to wait until November? We want our Mommy.
