what if sherlock never existed?
Of course he was merely a fictional character by Arthur Conan Doyle, but what if Sherlock the character was merely a fiction of Watson’s imagination?
Which is why he thinks Sherlock, someone who is constantly putting him in danger, is his best friend. And why Sherlock cannot live with buggering Watson, because Sherlock is part of him.
and also why Sherlock is able to escape from fatal situations, only to return to Watson in the end.(tv show wise i mean)
