Mr. Dark was attuned to people's emotions, their desires, fears and every other mundane thing they went through. Mr. Grayson was oddly muted to Mr. Dark, it threw up a series of red-flags but really.. what would anyone try to do? Investigate the carnival? It was normal to everyone except the people who were the most susceptible to its charm. That being said, with the rush of emotion that Grayson nearly let loose in wake of his past, Dark felt a faint wash--like the brush of a woman's caress on his consciousness--that caught his attention. He tipped his head, reached out mentally to grasp the thing and felt it slip away from his reach.
How interesting, that Mr. Grayson could keep himself aloof from Dark's.. dark charm. He couldn't get a good reading of him. Dark examined his companion for a moment, and then smiled his dramatic little smile.
"We'll take a tour, and if the circus is up to par for my desires and my carnival enough to suit your tastes then we'll sign the deal. Yes?" he said, pragmatic.
