He's probably going to pay you a visit to find out just exactly how you've managed to kill the Clown Prince of Crime when pretty much no one else has. And by accident no less? Sounds suspicious ...

But if you're telling the truth, he'll poke around for a bit and then vanish into the night and all you'll have to worry about is Harley and whatever posthumous revenge schemes/pranks the Joker has up his funeral suit sleeve.
