The limp returns.

It's weeks before he's not thinking of Sherlock with every breath, but eventually he isn't. It's months before the nightmares fade, but they do.

Over the next three years he finds a new flat, gets a new job in a thriving surgery, finds a pretty girl who loves him, gets married.

He's accepted it. He will always believe in Sherlock, but he's moved on. Sherlock's gone.

"He was the best man, and the wisest man, I've ever known," he posts on his blog.

He writes a book.

It gets published. Life is comfortable.

Then Sherlock comes back.
