Balthazar had already polished off two Bloody Mary's and was on Dracula's Revenge, which was two parts vodka, one rum and cranberry juice for the blood effect. He was now mixing another drink when he felt someone coming close to him. The angel's perception was piercingly sharp as Balthy turned and smiled at the man---uh creature. Man? Surely, a human.

"Goodness! What a costume, darling! Surely, you're not, are you? A real vampire? How delightful!"

The angel raised a curious eyebrow but couldn't detect any undead aura from this man. He did, however hear a heartbeat. So he was alive.
