Oh god, Iris just outright screams to Dent that he's a pain and Dent, for the first time, actually reacts to it because Iris said it right to him.
It causes Dent to go sulking about. Now I wonder what did Iris say to Dent which resulted in him recovering quickly from his depressed state.
Man that was just hilarous. Now why couldn't Iris do this before instead of simply just groaning at Dent's antics? The result was just priceless.
