Each time another round was ordered, Vash took another bottle from a serving wench. He tried to make himself as sullen seeming as he was sober and somber to portray further drunkenness. Mostly that involved leaning on the wall more and more from shoulder to flat on his back as he waited for the invitation sender to get to an actual point beyond having a crowd watch him play with his horns.

Finally he speaks up, and does a great job at saying nothing. So Vash listened and waited. Measuring everyone else up as he pondered his own response. At least he learned already that this was clearly no holy warrior of the old ways...That fact alone set him more at ease for reasons he did not know but dug at the back of his head.
