Continuity mistake: Sherlock and Watson are riding in a limousine. They are seated on the back-facing seats of the limo. Thee are 2 passengers seating on the back seats. The street background visible through the back and side windows shows traffic and the limo moving forward. Some shots of Sherlock show the background traffic moving in the right direction (backwards) and one shot shows traffic moving in the opposite direction, as if Sherlock was seating on the back seat or the limo was moving In reverse.

1 continuity mistake in Possibility Two - chronological order
Starring: Lucy Liu, Aidan Quinn, Jonny Lee Miller, Jon Michael Hill
While You Were Sleeping - S1-E2
Other mistake: When Sherlock was slapped, he later says he was surprised because the girl who slapped him was a "lefty." Then he rubs his right cheek and says it's leathery from all the slaps he's gotten, while the left is soft. This is backwards - anyone hitting him with their right hand would hit his left cheek.
Incel: Who are they?
Sherlock: That's Homeland Security.
Incel: But...you promised you wouldn't tell them about me if I talked to you!
Sherlock: Yes, but you play den mother to a pack of would-be rapists and mass shooters, so you can see how lying to you would be the highlight of my day. Look on the bright side - you don't seem to enjoy the company of women, and that shouldn't be a problem for the next five to ten years.
The Hound of the Cancer Cells - S2-E18
Trivia: "The Hound of the Cancer Cells" is a loose reference to "The Hound of the Baskervilles", perhaps the most famous of the four Sherlock Holmes novels.





Chosen answer: M broke into the brownstone and left a note. Holmes deduced he was staying at a high-class hotel from the soap scent on the note, and gave a picture from a hidden camera to his "irregulars" on the street to stake out hotels. One of them saw him, so Holmes followed him to his next intended victim and knocked him unconscious with a baton.
