Do you sometimes ask yourself what would happen and how different your life would be if you never met someone, didn’t answer a question the way you did, acted differently or accepted the advice of certain people? Because John Watson often did, quite often indeed. what he would have done if he never met Sherlock Holmes, where he would be if he never visited the apartment at 221b Baker Street with him, didn’t tag along to the crime scene with him, or listened to Sally Donovan or Mycroft, or the other hundred other people that warned him to stay away from the “psychopathic” detective. But John didn’t. He didn’t do any of it, and often thought about another life that he could have, had he done just one thing differently.
In many of those fantasies, he questioned if he would still live in London - probably not, the rent is simply too high for an ex-military doctor. But what if he somehow still did live here? Would he have run into Sherlock on the streets?
