If my “Two narratives overlapping to create one picture” meta is correct, John actually got a man’s phone number after flirting on the bus and Sherlock will be approached similarly by a woman in TLD.
No one is allowed to call me names or insult my intelligence unless you first read my “4th Agra Agent” meta I just posted on The Six Thatchers. Go ahead. I’ll wait.
So my theory says actions by our characters are overlapped with actions of other characters to create a completely false visual of reality in almost every scene in The Six Thatchers. It’s summed up best by this picture:
Boom. Two scenes happening at once. Two faces become one. Beautiful.
So this means John on the bus could be flirting with any other person in that universe. We see it as a woman because this is in Sherlock’s POV and he would naturally assume Three-Continents Watson would flirt with a woman. Balance of probability and whatnot. Even though John Watson has been shown as bisexual since the minute he said to Sherlock “You’ve got a boyfriend? No? You’re unattached, like me. Good.” and licked his lips in hungry anticipation. Seriously, if you haven’t picked up on this by now, you really need to go back and watch episode one. Better yet, watch the unaired pilot episode. It may make the rest of series 4 easier to swallow.
We know Sherlock is getting a “friend” in The Lying Detective because the Sherlock fandom is crazy and we follow them around when they film in London. This woman is played by the same actress as the woman John meets on the bus. Hmmm. Very fishy indeed. My theory allows for this to happen though: Sherlock is the one who gets approached by that woman, John is the one who gets the phone number from a man.
Imagine John gets on the bus and sees a beautiful man making googly eyes at him. John slicks his hair. John smiles and gets off the bus (or whatever mode of transportation he actually happens to be on). John finds he still has a flower in his hair. The man says “I like your daisy”. This would be a direct mirror to The Private Life of Sherlock Holmes, where everyone thinks Watson is bisexual while wearing a flower in his hair. And we all know by now Moffat and Gatiss LOVE that movie.
“Half and half!” — This is it. Solved. Case closed. Byeeeeee.
Continuing on anyways, the man says “I don’t usually do this sort of thing”, John flashes a smile and his wedding band, and accepts the number, later texting the man nothing but “hey”. He doesn’t cheat. The texts we saw are from either Sherlock or Harry (my bet in now on Sherlock), but he does run into him somewhere else as John texts him to break it off before it begins. BUT because Sherlock’s been the one constantly in contact with John and at the top of his inbox, John messages him the break-off text by mistake, giving Sherlock and therefore the audience the false impression John has been cheating on Mary with another woman. Whoa.
The subtext of John’s blog says Sherlock will be getting a fake girlfriend (fake could mean imaginary) because Sherlock is a mirror for Chris Melas in The Geek Interpreter and the episode will revolve subtextually around queer people forcing themselves to be heterosexual against their will. Read my deductions here.
So if mentally-unstable Sherlock gets the “girlfriend” who is actually the same woman John supposedly met on the bus, then John will be given the phone number of a man we may have already seen in Sherlock’s universe.
Ready for The Lying Detective to seem like a trippy, fake reality that questions everything you’ve seen, but is really showing you actual events from previous and future episodes? I am.
