The statement on John's blog mentioning the BBC, John and Sherlock looking directly into the camera, the camera that can be seen in the Morocco scene in TST - what if it was a show within the show? As in Sherlock and John are filming something to be broadcast on tv in-universe (for whatever reason)?
