Seth didn't laugh, but he did smile again, a tiny crook in his mouth like a scythe. He didn't really care whether or not Kitty went crying off to an authority figure later. He just wanted to have his bases covered if she did. If he had such explicit consent--well. Who could blame him?
"It's your loss." He shrugged, straightening his peacoat, and just looked at her. Where Charles had his device of touching his temple, Seth had no tells. She wouldn't feel him in her mind, quiet and subtle - he didn't even know if that was possible, because it'd never interested him to try.
So he looked at her, and into her, sifting carefully for whatever he might find, and his smile didn't shift an inch. Every lie, every indiscretion, every painful memory--he could find them all.
