If anything, the Inquisitor all but greenlit Markus. He told Markus about the Sewing Circle, about the cult when he could have kept that information to himself, and gave Markus ways to contact himself and the exchange 'if he ran into trouble.' No, if anything, the man expected that Markus wouldn't drop it. However, he made it clear that he would only work on the case if hired as a consultant or field agent. Markus was not interested in being a field agent, and if he were in control of the hiring process, even he wouldn't hire himself.
Markus gestured towards the bartender with a smile, getting her attention. “One more, please,” he asked, as he nodded towards Max. “And anything else he wants. Please put it all on my card.” Markus informed, still fully intending to go through with what he said, and if Max wanted another, he would include that. If not, then that would be fine as well.
“Of course, and do not worry, I have no intention of asking you anything more,” Markus responded, towards Max. He understood how nice the answers were, though he had no intention of looking for a partner, especially one with such a different opinion. And, he no longer intended to ask his remaining questions; he knew Max had no interest.
