The end is played when the Joker kills Commissioner Loeb, Judge Surillo, and comes for Harvey Dent at the party saying: 'We made it'! The name comes from the Joker line: "There's a lot of potential for aggressive expansion."
5 "Always a Catch" 1:39 The beginning is while the Joker wildly guns down other cars demanding Batman hit him. This line is not said in the film, but would have been placed during the scene where Gordon and Batman discuss the Joker's ferry situation.

There's no time- we have to go in now-" and Batman responds: "There's always a catch with him-" before getting ready to rescue the hostages from the hospital.

The title comes from Gordon's final monologue when he describes Batman as, "a silent guardian, a watchful protector, a dark knight."
