Molly walked into the lab, coffee in hand, and placed it on the bench next to Sherlock.
"Thanks," he mumbled, not bothering to look out of the microscope. "John, could you?"
"Could I what?" John answered.
"Coffee," Sherlock stated.
"What about it?"
"I need a drink."
"And?"
"Bit slow today, are we? Could you please help me take a sip? I can't look away from this; it's vital that I observe how these cultures change in the next 30 seconds." John stared at him incredulously. This was taking it a bit far.
"You couldn't just wait?"
"Don't be silly, of course not. By the time I'm done the coffee will be below optimal temperature. You know how I take it," Sherlock said matter-of-factly. John sighed and lifted the cup to his lips. Sherlock drank and let out a satisfied sigh. "Thank you."
"Don't mention it."
Molly stared at John and Sherlock, perplexed, flustered, confused.
"Oh, Molly. We're having a few people over this weekend. To make up for Christmas; being interrupted and all that. Sherlock's promised to be nice this time. And Harry's been begging me to bring her over for months now. You should come," John proposed.
"Oh, um, sure, I'll come," said Molly, smiling nervously. "Who else is coming?"
"Oh, same as last time, really. Sherlock and I, obviously, you, Lestrade, and there's no way we could keep Mrs Hudson away. Oh, Sherlock, is Irene coming?" John asked. Molly quickly glanced up at Sherlock.
"Don't know; haven't asked," he mumbled, absent-mindedly.
"Well, make sure you do, Sherlock, or you'll have no one to talk to." Sherlock looked up from the microscope.
"Don't be ridiculous; you've just said all the others will be there. If I, for some reason, feel the need to talk to someone, there'll be plenty of options."
"You know what I mean, Sherlock," replied John. Sherlock simply shook his head and returned to the microscope. Molly continued to look at him, trying to glean some tidbit information from his expression. Did he want her there? Was he just going to embarrass her again? What about the Adler woman? Did Sherlock want her there?
"So, Sunday," John broke the silence.
"Yes! Shall I bring anything?" Molly asked.
"Just yourself; Mrs Hudson's got it all sorted already," he explained.
"Righto, then," said Molly, turning to leave.
"Dress up nice!" called Sherlock after her. Molly paused.
"What?"
"I daresay Lestrade will appreciate it," Sherlock grinned. Molly blushed and strode out the door. John simply stared at Sherlock, confused as ever. "What?" Sherlock asked.
"Nothing," John trailed off.
