A Scandal in Belgravia - S2-E1
Continuity mistake: At Buckingham Palace, Watson has just sat down next to Sherlock. There is a red pillow between then on the couch. It moves, sometimes sitting straight and sometimes tilted, between shots throughout the scene. (00:14:45)
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.
