now, are you seriously trying to convince me that as Moffat and Gatiss wrote this super cheesy episode that looks a lot like a bad american procedural from 90s they were thinking about bringing up a secret sister at the end of the narrative arc?
You guys….I think this could actually be The Lost Special. ( O - O)
In the Unaired Pilot, sometime around the ending, Sherlock and John are flirting away, BUT in the background there’s a shop window with the number 57 on it.
Fast forward to A Scandal In Belgravia! How many of Irene’s texts had John counted? 57!
This next one is a bit of a stretch, but in The Six Thatchers John got 59 missed calls from Mary. Add 57 with the last two times the number was brought up in the show and you get 59!
AND NOW IT’S SHOWING UP HERE! WHAT DO WE SAY ABOUT COINCIDENCES!
