A few times I’ve cried while writing something. And that sequence there [Sherlock’s best man speech], I was blubbing (sic). The sad stuff doesn’t make me cry when I write it, because I know I’m being manipulative. But a simple declaration of devotion in the manner of the man who simply decided, “That is what you do.” He’s read it in a book: “You state how you feel about your friend.” Right. Will do that. And he does it with forensic perfection. So it kills you when it happens. It’s tremendously powerful. And it’s very key to the character of Sherlock Holmes because he has no shame in admitting that he can feel that way. When he likes people, he’s perfectly happy to like them. It’s just that he doesn’t like very many.
I wasn’t referring to the fake stuff they filmed last year. I was talking about the extra shots they did as they filmed Reichenbach.
We’ve worked out how Sherlock survives, and actually shot part of what really happened.
—Steven Moffat, January 2012 (aka just after Reichenbach originally aired)
And we know he wasn’t lying about filming extra stuff, because if he was then Louise Brealey wouldn’t have been there in costume at that time.
Setlock wasn’t setlock back then. Seriously, just try to find as many photos as you can of them filming the original fall for Reichenbach. I bet the total number will be less than the number of photos you can find of just Martin lying on the ground during Empty Hearse filming.
The footage I’m talking about isn’t plastered all over the web, and we currently have no reason to believe any of it was filmed as a red herring. (You could argue that they totally changed their minds about the solution and threw the old stuff out, but given the preponderance of the evidence I say they’re saving it for the true explanation to be seen in Series 4.)
