I think I'm talking to someone who's also his friend, and who doesn't want to spend time we haven't got fighting among ourselves on a broad scale. You and the others want to go after him? Fine. Shall I tell you the Joker's on the loose right in the area we're in, and he's just learned that his arch-enemy and object of his obsession has been killed? I imagine he's a slightly higher priority if you're looking to start a manhunt.

And you have a network if you want to talk to him privately. Or I can relay a message to him if he's not taking your calls.
