A/N: So i didn't realize I was going to make a second part of a story until I finished writing it, but here I am writing this. this is the second part of John's chair it going to have a different title though...
BTW: SPOILER! Season 3 episode 3 the ending so I devise not reading this of you don't want you heart crushed.
If I owned BBC I would get Season 4 to come out now!
After Sherlock said goodbye to John for the final time, of what we thought as the last time, Sherlock boarded his plan.
He nearly when four minutes, that gave Sherlock enough time to finish his video and connect it to every electronic device in London. If you've seen the last episode than you know what video I'm talking about.
He did this so he could stay in London get back to John, let alone that he could live, he already spent two horrible years without him, he was not plan to let go of him this time. Therefore he made a believable reason that he should stay in London.
To make Moriarty come back to life, that was the more reasonable assumption that Sherlock could think of to see his way back to Backer Street.
Now, all that Sherlock needed was a great case to show how amazing he was to John and how much John misses that thrill of the game. To get his doctor back to Backer's Street to where he belongs. Next to Sherlock.
