Actually it should be common knowledge that Sherlock Holmes stories can not work without John Watson. Because without John Watson Sherlock Holmes would just be a weird nerdy crow solving cases. It is John Watson who makes him famous, who tells his story, who gets him away from drugs eventually.
Nevertheless we still get adaptations where John Watson is erased because he is... boring? I don’t really know to be honest. One of the most recent adaptations who also erases John Watson is ENOLA. In the Enola movies Sherlocks cases are always discussed in the press, he is a superstar... even though he has no partner who writers down his cases for him. Weird plot hole, but thats not my point today
But - even though the movies erase John Watson - they still drop a really interesting line why a Sherlock Holmes story without John Watson can never work. Sherlock offers to work together with Enola and says:
Enola rejects the offer and responds with:
But why does she rejects the offer, even though she also admits that it would be her dream to work alongside Sherlock? Yes she says “I would be always in your shadow”. But thats only half of the truth. For Enola a Holmes&Holmes relationship wouldn’t be good because she would always be in Sherlocks shadow. But what about Sherlock? Why would a Holmes&Holmes relationship bad for him? Would he really be lonley if he would work together with his sister? Sadly the show never really gives an answer to that and “only” uses this scene as a set up to introduce Watson.
Good for us CBS Elementary my beloved also had an episode with the same topic and digged a lot deeper into the question why Holmes on his own (aka Holmes&Holmes) is super hurtful for Sherlock. The episode is season 3x19 and has the glorious title “One Holmes, One Watson”
Short summary: To cope with a trauma Joan tries to turn herself into a second Holmes, to get rid of friends and emotions that can potential hurt her again: Holmes&Holmes. Sherlock realizes that this isn’t a good idea and give a beautiful and very on point summary why a Sherlock Holmes story can never work without a Watson:
But why doesn’t it work? Whats so problematic about Holmes on his own aka Holmes&Holmes? Enola sadly didn’t gave us an answer to that. But Elementary did a few scenes later:
This is why every Sherlock Holmes story needs a John Watson. Because Sherlock Holmes on his own is not complete. Sure, he is a brilliant problem solver, a lover of dogs, a chemist. But he is also anti-social, has a drug problem, has a little EQ and a fucked up night&day rythm.
John on the other hand is emphatic, nice, friendly, makes friends easily, enjoys his sleep. But he is also traumatized from the war, struggles to get back on his feets and to face his trauma.
You know the theory in greek mytholgy about the spherical humans? The spherical humans contains of two humans, fitting together perfectly, forming a round body. The gods were jealous at the humans because together the spherical humans had a really strong power. So the gods cut the spherical humans in two parts and placed the parts all over the world so they would have problems finding their fitting part again. And now every human is searching for their missing part, so they can eventually form the spherical human again and become stronger together.
John and Sherlock are a spherical human. Sure, one half can work without the other, but they are weak like this. And so is the story: weak.
You always need both of them.
This is not something I made up. It was also already written down in the ACD canon:
“It is both, or none," said he. "You may say before this gentleman anything which you may say to me." - A SCANDAL IN BOHEMIA
Of course I do not expected the Enola Holmes writers to be familar with ALL Sherlock Holmes stories (of course I do but if I say that out loud I sound like a purist again), because it is about Enola but you should at least be familar with some basic concepts/rules for the original ACD canon characters. That includes the scene above... and of course The Three Garridebs and the CAM case. Hand holding behind closed curtains!
And I honestly fear that the writers of the Enola movies have not understood yet that it is always “both or none” and only introduced John Watson because he necessary for the next storyline to come. I fear that they only know what to do with John Watson as a character when he is relevant for the story, and do not know what else to do with him... On the other hand: Sherlocks lonliness is mentioned around three times in Enola 2, so the writers do seem to be aware that Sherlock needs his Watson? But why wait until the end of Enola 2 to introduce him? Didn’t they knew where he fits into the storyline of the second movies?
Anyways: I hope that when writing the script for the third movie they slowly will become familiar with Watson as a character and slowly find out where his place is in the Enola movies. (At least I hope so, movies where they are just cold distant friends, is the most unpleasant thing to watch imo... IF we get Enola 3).
TL:DR: Don’t seperate Sherlock Holmes from John Watson
