In The Dark Knight, the Joker talks to Two Face while they are inside the Gotham General Hospital.
The Joker explains that he didn't plan the kidnapping of Rachel and Harvey, since he is clearly a person who does not make plans. Is this a lie and why would he lie about it?
Secondly, the Joker offers Harvey a gun, who decides to pull the trigger pending his coin-toss. How likely is it that the Joker would risk his chance to break Batman in a coin-toss, or asked differently, how likely is it that the gun was actually loaded in the first place?
