Continuity mistake: The scene where Sherlock says "Vatican Cameos" he is seen to be facing the right side of the shot. Yet in the shot before that he is facing the left side of the shot from the back.
Continuity mistake: Sherlock is dancing with the bridesmaid towards the end. When they stop and are talking with Watson, Sherlock's hands keep switching from being behind him to in front of him, depending on the camera angle.
Chosen answer: That line of dialogue has never actually been spoken in any of the Sherlock episodes, during seasons 1-4. However, that line is written in someone's fan-fiction story online, where it's said by Sherlock and directed at Anderson.
