… and so sherlock and john never met. the end.
THE SHOW WOULD CONSIST OF JOHN LIMPING AROUND LONDON AT VARIOUS SPEEDS
“Who’d want me for a flatmate?” John asked, completely serious at the notion that anyone would actually want to room with him. He glanced at his old colleague when he heard him chuckling. “What?”
“Nothing, I just remembered a funny joke.” He said with a smile. It probably had something to do with two flatmates or something. John didn’t inquire.
“Oh.” He responded simply, returning his gaze to his cup of coffee. After a few minutes of silence, John looked up to ask Stamford a question but stopped when he saw a curious look on the man’s face. He almost seemed horrified. “What’s wrong?”
“Nothing.” Stamford stuttered. “It’s just…” He seemed to be trying to get a look at John’s back. “I just thought I saw something on your back.”
The Watches’ verse (by bendingsignpost) doesn’t have that particular plot, but it does have several parallel timelines, one of which is more or less the show, and others where John doesn’t meet Sherlock (at least, not in the same way). I don’t want to spoil it, so I won’t say more, but it’s really good. There’s also a bit that could be considered time travel (sort of), which delighted me, because parallel universes and time travel are two of my favorite tropes.
That said, I would totally read a Turn Left!AU, (even if I don’t read much Sherlock fic anymore).
