GUYS!!! What if Moriarty is no longer the principal enemy to Sherlock but a equal to be reunited with?????
In the official trailer of the final problem, we can see this scene where Sherlock is walking from a helicopter to somewhere. He holds a bag. Seems not to be stressed at all, rather impatient I would say. And the helicopter is the same as shown on the first photograph of Andrew Scott, Jim Moriarty!!! What does it mean?????? <3 <3
