Yeah, (from the novelisation) it was Joker getting into a SUV on street level, gasping for breath and laughing - touching a streamlet of blood running down his chin with a forefinger and licking it.
Joker: "Yummy, did you see that? Did you love it a great big bunch? I tossed the lovely bird into the wind and out Bats went. I wonder... would the Bats take a header for everyone? Or is that pretty little birdie someone special? Either way, we know one thing for sure now...Batman will always try to save the innocent. And that will be his downfall!"
Driver: "What about Dent?"
Joker: "Oh, I'm a man of my word."
