(Spoiler warning: If you haven't yet seen 'Sherlock' Season 4's "The Final Problem," good god what are you waiting for?)
Well, this final episode of Sherlock Season 4 was packed with Easter Eggs big and small, and it even teased some potential paths the show could take in Season 5 — although the cast and producers have not confirmed if and when it will happen *stresses*. While we have to acknowledge that there was a certain finality about "The Final Problem," Benedict Cumberbatch himself said, "We never say never on the show."
But in all the excitement of Moriarty returning (if only in flashback form, uff), discovering the truth about why Sherlock has, ahem, difficulty making friends, and coping with Eurus's anxiety-inducing Saw-like game, there might have been some things that slipped by unnoticed. So here are seven things you might have missed in Sherlock Season 4, "The Final Problem":
1. 'The Three Garridebs'
"The Final Problem" has a nice little callback to Sir Arthur Conan Doyle's Sherlock Holmes story "The Adventure of the Three Garridebs," in which an American by the name of John Garrideb needs to find two other Garridebs to split $15 million with as part of the terms of inheritance. It later transpires that John Garrideb was not his real name and he was actually a fugitive of the law who was trying to get his greedy hands on $5 million.
In the BBC's version, there are three brothers named Alex, Nathan and Howard Garrideb (above). One of them is the killer of a man called Evans and Sherlock has to solve the crime as part of Eurus's cruel game.
2. 'You Said You Liked My Lady Bracknell'
In the episode, Sherlock and Mycroft joke about Mycroft's role as Lady Bracknell in Oscar Wilde's The Importance of Being Ernest. The play is in fact all about a long-lost brother whom Lady Bracknell reveals at the end.
3. Sherlock's Friend Victor Trevor
No wonder Sherlock has problems making friends! The poor guy's childhood best friend was drowned in a well by Sherlock's own sister. This little friend's name was Victor Trevor, who was actually introduced in Conan Doyle's story “The Adventure of the Gloria Scott” as Sherlock's good friend from university. Here's the excerpt from the text:
"You never heard me talk of Victor Trevor?" he asked. "He was the only friend I made during the two years I was at college. I was never a very sociable fellow, Watson, always rather fond of moping in my rooms and working out my own little methods of thought, so that I never mixed much with the men of my year."

4. The Dancing Men Code
At the end of "The Final Problem," Watson and Sherlock put the Baker St. apartment back together and we get a shot of a blackboard with little dancing figures on it. These figures are actually a code Sherlock deciphers in the story called "The Adventure of the Dancing Men," which was also Conan Doyle's third favorite Holmes story.
5. 'The Final Problem'
The episode is fittingly named for the short story depicting the showdown between Sherlock and Moriarty. Conan Doyle's fourth favorite Holmes story pits Sherlock against his arch nemesis Moriarty at the Reichenbach Falls where they attempt to solve the "final problem" of their survival. Although the BBC's Sherlock already had his final run-in with Moriarty in the aptly titled "Reichenbach Falls," "The Final Problem" brings him back, posthumously in league with Sherlock's secret sister, Eurus.
6. A Subtle Nod To Basil Rathbone
Did you catch the cheeky nod to Basil Rathbone in the final shot? Thanks to intrepid Redditor sassinator1, we see respect payed to the famed actor who portrayed Sherlock Holmes in a series of movies in the 1940s.
7. Is It Twins? Please Let It Be Twins!
The episode also had a blink-and-you'll-miss-it mention of Moriarty's brother when Eurus explains all the pre-recorded footage of Moriarty for the "special" occasion:
"Moriarty recorded lots of stuff for me. His brother was a station master, I think he was a bit jealous."
Brother, you say? Could it actually be twins this time? I sincerely hope so because Andrew Scott as Moriarty was an unbeatable villain and we'd do anything to get him back in our lives — even if it takes magic, accepting implausible death-evading possibilities, or twins. I don't think I'm alone in thinking this was the best part of the episode:
