Sorry, I'm Sher-Locked

A Johnlock, Mystrade and Morene fanfic (BBC Sherlock).

Something had changed at 221b Baker Street, but John couldn't put his finger on what, exactly, it was. All he knew was he and Sherlock had been getting along just fine (and had even, in fact, been getting closer than ever before) when one day Sherlock stopped talking. At first, John wasn't worried. Sherlock was probably just in his mind palace, thinking of a case or something. He did say that he sometimes didn't speak for days on end.

After about a week, John started to panic. He was just opening his mouth to ask Sherlock if he was OK when he started talking again. Not as much as before -no where near as much- but it was better than nothing at all. All that silence was making John uneasy and awkward.

Sherlock seemed stiff and more strained these days, especially, Lestrade noticed, in front of John. At first he had wondered if they had had an argument or Sherlock had taken a strong disliking to John's latest girlfriend, but as the days turned into weeks, and the weeks turned into months, he knew something deeper was going on in Sherlock's fantastic mind.

The question was, what?

Characters and episodes referenced belong to the BBC, Steven Moffat, Mark Gatiss and Sir Arthur Conan Doyle. Plot of the actual chapters is mine, although some ideas are from other fanfics I have read on wattpad and tumblr (credit to the authors of them). The pictures don't belong to me (unless otherwise specified in the chapter they are found in).
