Benedict is at a point where he's unlikely to perceive any slights subtler than a slap in the face. When Atticus finds him again, he's in a group of young men around his own age, propped languidly against a pillar and maintaining relative silence while they discuss and dissect the female partygoers.
When addressed from his other side, Benedict seems almost glad for the distraction, and turns toward Atticus with a smile that pretends to be polite but is in fact mostly drunk and ingratiating.
"You understand right," he all but slurs, lifting his glass as though in a toast, "I hope your staff is prepared to meet my mother's standards."
