Hi guys, I have watched it all over and over. But maybe we miss a big clue. How does the Reichenbach fall begins and end? It begins and ends with John sitting and talking with a Psych. What about the thought that its all John's imagination, sort off. The story is told by John to the Psych. So there is NO way off telling that the situation on the roof was like John told. Mr Moffat always told the public they missed a big clue!!! People were thinking about the fall of Sherlock but what about a big clue about the whole episode? This could mean Moriarty is still alive and going. But that is just a theory I could think off
