"Oh, that won't be necessary." Lucius has, allegedly, obtained the information he required, if his easy dismissal of the rest of the conversation is anything to count by. Which is, apparently, that this Lucius has nothing at all to do with the fog and the profiteering that comes of it.

Most satisfactory. He is wry when he adds; "I expect you'd like me to leave before you collect whatever it is you've forgotten on your way out again."
