Picking up the theory trail where we left off: I don’t think Jim, Sherlock, Sherlock’s friends, or Mycroft are behind the video that appeared all over the country at the end of His Last Vow.
So who was? I’m gonna have to go with Moran. And not just any Moran…
…but the guy who was already in the show as a villain named Moran. (I honestly don’t know whether it’s sad or hilarious that we’ve reached a point where that’s a fringe theory, but here we are all the same.)
Let’s do a motive, means, and opportunity rundown.
But wait… if the reason Moran played the “Miss Me?” video was to bring Sherlock back, how could he have known things would play out like they did? If this plan was in place since The Empty Hearse at latest (in which Moran planned to have civilian surveillance bill passed), at that point (during TEH), how would he have known that he needed to get Sherlock back when the events that led to his exile hadn’t happened yet? How could he have known what would go down with Magnussen and Sherlock? This isn’t an attack on your theory, I’m seriously curious and want to see what you think.
