Mr. Darcy: "Might I play a hand?"
Lady #1: "Of course."
[he takes a seat at their table]
Mr. Darcy: "Good evening."
Lady #1: "So shall we..."
[Darcy places a bottle containing flies on the table]
Lady #2: "A potion?"
Mr. Darcy: "Carrier flies. [He lets the flies out] They're in the possession of but one truly enviable talent. The ability to detect dead flesh."
Lady #2: "The buzzing is frightfully loud."
Mr. Darcy: "Well it's not the buzzing that should concern you, madam, but rather when the buzzing stops."
Lady #2: "Oh, dear."
[Darcy stays calm and drinks from his glass before breaking it, using the broken end to cut the throat of the man identified as zombie]
