In fact, if the room had been quiet instead of buzzing with laughter, Parvati would have heard the sound of Draco's throat contracting in shock. But he was quick on his feet, and kept his lips together in a polite smile. He had to use every shred of his will power not to demand, "What do you mean, you don't know who I am?!"
"I read your questions you had for the Q&A session later," Draco began with ease. The session was really meant for a bit of bantering between the guests, and for miscellaneous announcements. "They're quite specific. It feels like you're performing our annual evaluation," he joked-- but he didn't allow his body language to become too intimate. He did not lean into her, or give her a little grin.
He liked to be a little hot and cold with women-- but especially this one, who apparently did not know who he was.
