A/N: Prompt fill for morbidmegz, it's a little different to what I was thinking of (and possibly to what you wanted) but I hope you like it anyway :) This is set after Sherlock's return :)

Well, it's Christmas time pretty baby
And the snow is falling on the ground
Well, it's Christmas time pretty baby
And the snow is falling down
Well you be a real good little girl
Santa Claus is back in town
Got no sleigh with reindeer
No sack on my back
You're gonna see me comin' in a big black caddilac
Oh, it's Christmas time pretty baby
And the snow is falling on the ground
Well you be a real good little baby
Santa Claus is back in town

"Oh good, you're here."

Molly suppressed a start as Sherlock materialised near her elbow.

"Yes, well, everyone else was busy with-"

"-Christmas," Sherlock finished for her, "I know. So are you," he added briskly, taking her clipboard away.

"What?"

"You are also busy with Christmas," he repeated, easily evading her attempt to reclaim the clipboard and setting it aside before starting to unceremoniously remove her lab coat.

"Sherlock!" she protested, moving out of his grasp and pulling her coat back on, "I have work to do, you can't just come in here and assume I'll drop everything for you."

Sherlock looked a little put out by her statement, before his face cleared and he flashed her a charming smile. "I cleared it with Stamford, Molly," he told her, "you have Christmas off."

Molly eyed him warily, "Why?"

For the first time since coming into the morgue, Sherlock looked unsure of himself, "I thought you might like to come and join us for Christmas."

"Us?" she asked, finally shedding her lab coat having decided he wouldn't try to get her fired.

Sherlock glanced at his phone as a text came through, "John has invited Mrs. Hudson and Lestrade to the flat again."

The sight of Sherlock on his phone and the prospect of a small Christmas party at Baker Street brought back painful memories to Molly and she suddenly found herself trying not to cry.

"Oh," she said quietly, turning away from him to hang up her lab coat.

Sherlock looked up from his phone and frowned, confused by her subdued reaction. He looked back down to send his reply to John and froze, suddenly realising what had upset Molly.

"John wanted to know if you were coming," he explained in a low tone, slipping his phone back into his pocket.

Molly nodded without turning around as she slipped into her winter coat.

"You are coming aren't you?" he asked, suddenly unsure.

Molly turned around and forced a smile, "Of course," she assured him, putting on her beanie, "but it's been a long day, I can't say that I'll be very good company."

"Good or bad this is my first Christmas back home and I want you there," Sherlock told her firmly.

This time Molly's smile was more genuine, "I thought you didn't care about Christmas."

"I don't," he confirmed, slinging her bag over his shoulder, "I have much more important things to care about," he added with a meaningful look.

Molly blushed and looked away, missing Sherlock's smirk as he pulled her arm through his and led her out of the morgue.
