Irene Adler knew how to compose herself, even if on some level Moriarty suspected she was worried. Not unnerved, just, maybe wondering what she'd let herself in for meeting him. Or maybe he was just assuming that because most people did. She was hardly most people or he'd never have picked her out of the ridiculous amount of people that he heard of that wanted his consultations. She knew she'd had powerful information, what he'd given her was simply a push in the right direction. An idea of what to do with it, from there she could do what she wanted, so long as she'd done him a favour or two.
He sat after she did, gentlemanly as usual, which sometimes surprised people, the posh boy from Dublin had manners that he'd never let go of, even after everything he'd done, and would do. When she told him she could never think of him like a client though he couldn't help but laugh at the thought of it. Not that he believed her for a second. "Oh you have, you've thought about it, don't tell me you haven't. You've wondered could you make me beg for you. You're wondering it right now. It's fine of course, no different than me imagining just what elegant things I could craft with your skin. Don't be ashamed of what you are, and don't be afraid of what you say to me. Being afraid of me is more than enough but most people say that's just sensible!" he laughed, his voice inflections showing a wry amusement at the thought.
"As it happens, The Woman, is everything I expected and some more besides. I'm sure you have all manner of men and women quivering in their restraints. Tell me, Irene, which sex is harder to control? I have some theories myself but I suppose I come at it from a different angle don't I. Its easy to control anyone when you know what they'll die for, what they love most in the world. You do it through lust, pure and simple lust. It's a bit base but whatever floats your boat."
And in the next breath, "Wine? This place does a rather divine merlot"
