I do not own Sherlock or Doctor Who
I wasn't really sure what happened at the time. I was just glad Sherlock had lived. He had to stay in the hospital a long time after but he wasn't injured as bad as they thought he would be.
After losing his best friend twice he was in a real state. It took the Doctor and I a trip to the end of Earth One again to get him to cheer up.
I had the Doctor explain what hapened with the watch.
When Moriarty had the watch he could see two possible outcomes. If Sherlock got in the cab John would have died and he would have lived. The second option was that they never got in the cab and followed him. In this reality he saw that Sherlock and John would die but then you and I interfered. Lying on the ground looking into the watch Sherlock saw the wreck and had a decision to make. He decided that the wreck was a better way to go to make Moriarty lose. In doing this, our reality never existed. We still have the memories but they are like a fable we have been told. They aren't real anymore.
When I told him I didn't understand he just smiled and said," That's the curse of a Time Traveler."
Standing on top of the Statue of Liberty holding Sherlock and the Doctor's hands I don't see it as a curse. I see a blessing. I want this to last forever.
