"Sherlock?"
He blinked and looked down, seeing Molly shyly smiling up at him, her left (ringless? WTF?) hand on his chest. When she noticed him staring down at her finger, she shrugged. "We broke it off. We both knew it was a mistake. And you looked sort of…lost, so I thought I'd just…" Her voice trailed off and she shrugged again. "I guess you were just in your mind palace, I'll just…" She gestured vaguely to the dance floor and her (ex? ex!) fiance, who was still flailing about with Mrs. Hudson laughingly dancing next to him.
"No!" Sherlock's hand shot out and grabbed her wrist just as she started to turn away. "No," he said again, more quietly and (he hoped) less desperately. "I'm sorry about your engagement, Molly. Would you, erm, like to dance?"
The music, as if conspiring with him, turned into something slow and sultry, the perfect reason to take her into his arms and sweep her back onto the dance floor even before she'd finished nodding 'yes'.
