[Sherlock x Female OC] The thing is, there is an empty, gaping hole at the base of John's throat where his overwhelming guilt and periodic bouts of torturous grief used to be. It would be so easy to... to be angry and punch a hole through the wall, through the foam of his pillow -- drive his fist through Sherlock's heart. But he remembers; in the most tragic and inopportune of fashion, remembers how angry he had been when Sherlock had jumped, how furious he had been at his funeral, and how it hadn't stopped him from breaking down at his grave nonetheless. The thing about his anger is this: it does nothing but leave him behind in the end, a bundle of nerves and frailty in his bones and an unsteady sway to his gait. It does nothing at all, but reduce marginally the constant, suffocating oppressiveness of his days bleeding into one another with a burst of adrenaline. The thing about his anger is this: it doesn't give him back Sherlock. So he gets a new flatmate- a woman named Holland. They were great friends at school and in fear he would be lonely again after Sherlock died he started to meet up with her, and soon, she moved in with him. They're just friends, though. No one could have a bond with John like Sherlock did. Sherlock was his best friend. But then Sherlock returns, and John is more furious than ever at him. Also, Sherlock and Holland seem to bond quite well, which is something Sherlock finds too complicated to explain itself.

Only four people know of the true state Sherlock Holmes was in just before he met John Watson. The darkness, the drugs, the voices, her. You could argue that her death triggered it. Now that John has left Sherlock to live with his wife it is inevitable that Sherlock will go back to how he was. Until somebody knocks on his door. He wasn't the only one to fake his death.
