At some point around the halfway mark, Batman, Gordon, and Dent meet on the rooftop. It should be noted that Dent's election plays a signifcant role; he's seen as the sort of JFK of Gotham; he;s gonna help save the city from crime. Anyways, their on the roof, and Gordon's a littlw weary about letting ihm talk to the Batman; Gordon and Dent don't get along THAT well-they get along, but there are arguments between them. Gordon doens't really trust him yet(this can be confirmed by set reports of a scene with Gordon yelling at Dent-excel)-anyways, having earned their trust, Dent is with them on the roof, talking, and Batman tells Gordon and Dent SOMETHING. Something he is going to be doing in the near future. We follow Batman on this quest, when suddenly the Joker and co. show up. What follows is the films big huge action chase...and a character dies here...so of course we forget that the Joker conviently guessed as to where Batman would be. Later, during a party scene, The Joker kidnaps Rachel while Harvey Dent tells the world hes batman. Of course, if he really meant it, in a town like Gotham he'd be killed within a few hours. But of course he has nothing to fear, to because hes really working with them. When Rachels kidnapped, Dent gets upset she was involved, and Maroni n his boys are now on trial, he threatens to talk against them unless Rachels freed. Que Dent getting mauled with the acid. Then, in Batman and Jokers final confrontation, somethings going down when out of nowhere TWO FACE shows up...Batman thinks hes there ot help when he does SOMETHING which gives away that hes really bad...thinking they have Batman cornered, Joker explains how Harvey Dent was really working for him...but Two Face has some of his own tricks up his sleeve...the ending is batman brings in the joker, but, as he says with Gordon at the end..."As we bring one in, there will always be another", meaning Two Face has indeed escaped.
