A/N: This one is for Ladida who requested Sherlock stalking Molly & John when they go out for dinner. Once again, I've changed it slightly but I hope it still works!

Greg Lestrade took a sip of his wine and tried to remember the last time he'd had so much fun.

Not only was he doing a nice thing for a friend but he was also content in the knowledge that he had somehow managed to get under the skin of a certain consulting detective.

His contentment vanished as he caught sight of a waiter who looked suspiciously familiar and he choked on his drink.

"Are you all right?" Molly asked in concern, patting his back as he continued to cough.

"I'm fine," he gasped, "I just…thought I recognised someone."

"I hope it wasn't someone you know professionally," she quipped; he smiled as he loosened his tie and took a sip of water.

"Not exactly," he replied cryptically, he looked up and caught the waiter's eye. He shook his head as he recognised him, "Unbelievable," he murmured, torn between amusement and frustration.

"I'm sorry?"

Lestrade looked back at Molly, "Nothing," he assured her with a charming smile, "although I believe I have been remiss in my duties as a date," he continued, standing up, "shall we dance?" he asked, holding out his hand.

"I'd love to," Molly said with a smile as she took his hand.

"I was wondering," Lestrade began as he led her out to the dance floor, eyeing the waiter as he went, "just how much of a show you wanted to put on for your relations."

Molly's eyes lit up with mischief, "What are you suggesting?"

Lestrade pretended to think for a moment as he took her in the waltz hold, "Well, I did think that a slow and close dance number might be in order," he replied with a grin.

Molly smirked, "I think we can handle that."

Lestrade's grin widened as he pulled her closer, wondering absently why he'd never noticed her penchant for mischief before. Over her shoulder he could see the waiter's eyes narrow and he shot a wicked grin in response.

The music duly changed after a few moments and Molly rested her head on his shoulder as he pulled her a little bit closer.

Unable to resist he kissed her hand before resting it above his heart and she giggled, "You weren't kidding about a show."

"Might as well give them their money's worth," he replied in a low tone, smirking as he watched Sherlock abruptly turn on his heel and stalk from the reception venue.
