Sherlock visits 221B once before he leaves the country. He knows that John will be out; he couldn't possibly feel up to returning to the flat yet. So Sherlock goes back just to say goodbye to the old place. How sentimental of him.
He stands there in the living room, smiling sadly at his possessions- and then his eyes alight on a padded envelope that he knows hadn't been there before. It looks just like-well, just like the ones that Moriarty had used for their little 'game'. He crosses to the mantelpiece and retrieves the creamy package that is leaning against his skull. It's sealed with the same thick red stamp, and for a moment he experiences an intense sensation of deja vu.
Cautiously, he grabs a knife and slits ope the package. All that falls out is a DVD case and a tiny scrap of paper. He touches the paper first. All it says is, "Kisses! xoxo Jim". He lets out a low groan that could almost be a laugh.
Then he flips over the DVD case. There's a picture of Moriarty as Richard Brook with words in-ugh- Comic Sans underneath him: 'The Storyteller'. Really? Oh, sweet Jesus...
He checks his watch. Mrs. Hudson won't be back for another hour and a half. He's got time.
Sherlock puts the DVD in his DVD player, sits in his armchair and waits. After a few moments, Moriarty's smug visage flickers onto the screen.
"Sherly baby!" he cheers, grinning widely. "Didja miss me? I'm sorry, dearest, truly I am. But it's a dirty business, being your archenemy. Now, clearly, if you're watching this video, something went wrong on that rooftop, and only one of us made it out alive." He flicks an eyebrow. "Don't look so surprised, of course I knew that you were going to fake it. I'm not stupid. However, I am-" He draws a finger across his throat and makes a face. "Well, you get the picture." He smiles again, manic. "But hey, at least I went out with a BANG!" He laughs. Sherlock stares. His heart constricts the tiniest bit. Don't. He doesn't want jokes, he wants him back.
Moriarty-ah, fuck it, he's Jim to Sherlock, no matter how he tries to hide it- Jim makes a face of mock surprise and shame. "Too soon?" Yes.
"Ah, well. I thought that it was funny. Anyway, I'm dreadfully sorry for leaving you alone. But I did say that I was going to kill you, and if I didn't have the heart to burn yours out..." He pretends to stick a finger down his throat and vomit. "It's sad, I know. But who knows? Without me, maybe you'll die of boredom. The I win!" He claps his hand in an exaggerated display of excitement.
The insanity leaves his eyes for a moment and is replaced by something sad. "I suppose this is the last time, isn't it, dearest? So I should end with something special." He is silent as he thinks. "Ciao... Sherlock Holmes." He blows a kiss and then turns away. "Sebby, turn the damn camera off. I'm going to go shoot something." Sherlock belatedly catches the kiss and holds it like it's tangible in his palm.
The screen goes black.
