It takes both Hythlodaeus and the man a second to realise what had happened- bellowing suddenly, he falls to his knees, clutching his face. Pausing, Hythlodaeus looks down at him, then at Joker- then hears shouting in the distance.

"Ah-" There's no time to explain what he's about to do. He grabs Joker's arm, and the pair of them are teleported further into the Up in a cloud of inky darkness. Best to do that before they're both apprehended and Hythlodaeus' powers nullified.

Once they appear in their chosen spot, concealed in the alleyways of the Up, Hythlodaeus looks over at Joker with a frown.

"What happened back there? Not that I don't appreciate it, of course- but I'm unsure of what you did to him."
