The cabinet opened twice more - Harry shuddered at the note of finality that rang out across the room when the second drawer that had contained the locket slid shut for the last time. Draco dangled the locket by its chain in front of his face, and watched it spin slowly in a circle. He carefully wrapped the chain around his fist to bring the locket to his fingers. He peered at it, chewing on his lip, looking as if he were trying to gauge how best to proceed. He placed the locket on the cabinet and gripped it delicately between his finger and thumb to hold it in place. He glanced at Harry through the corner of his eye as he hovered the fang above the locket’s "S’, "Here goes nothing," he muttered, and he pressed the fang down into the locket with a firm but steady pressure.
