There was a single knock on the door to the lab, and Jim Moriarty walked in. He was wearing a Westwood suit and a smug grin on his face.

Sherlock didn't look up from his work at first, but his face tightened and the knuckles on his hands went white.

"Sherlock." Moriarty greeted him casually.

"Moriarty." Sherlock said through clenched teeth. He slowly turned his head to his nemesis and caught the glimpse of madness that was always hidden behind his eyes.

"What has brought you here?" Sherlock asked chattily.

"Oh," the man said with eyes that searched the room with interest. "I just came to pick someone up."

Sherlock grew silent in the next couple of moments. He stared into the eyes of his enemy that slowly turned to look at him.

"And what makes you think I'll come with you?" Sherlock asked provocatively, after quickly working out that he was the someone in question.

"Yes, I thought you might want to know that." Moriarty said playfully. He moved away from the doorway and with his hands suggested that Sherlock might leave through it. "Let's discuss it on our way, shan't we?"
Sherlock didn't move an inch.

"Well," Moriarty said with a grin. "I've got John."

Sherlock turned pale.

"You better come with me if you want your doctor back."
