Here’s the thing. I love Johnlock. It’s been a while since I’ve been this invested in a relationship between two characters. For a few years I actively avoided fandom because I didn’t have a platform to enjoy it on and thought that maybe I shouldn’t be spending all my time overanalysing TV shows. I had left Livejournal and not yet joined Tumblr, and I’d moved to a new city where I didn’t have fandom friends around me. I still don’t have ‘real life’ fandom friends that I see in person, but I do now have Tumblr, and so after a few years where my OTPs faded into the background, I’ve fallen completely for Sherlock and John. I’m a total Johnlock shipper, now and forever, but only when it comes to fandom. And I can understand why the arrival of Mary in BBC!canon complicates their relationship in the show, but I don’t see it as destroying the ship, because, for me, Johnlock was never a possibility in BBC!canon at all anyway. Not because of John, or Irene, or even because of Mary, but because Sherlock is asexual. It’s why I identify with him so much (oh, yeah, btw, to anyone reading this who has known me a while… there’s something you should know).
I LOVE seeing a deep and meaningful relationship onscreen in which there is no romantic or sexual expectation, and one of the characters is fundamentally not interested. Their relationship is amazing and gives me so many happy feels, because I aspire to that. That’s not to say that I don’t love Moftiss playing with the idea of Johnlock or using it at times, but it’s so refreshing for me that a character I love feels the same way I do about relationships. That moment in The Blind Banker when Sherlock turns up on John and Sarah’s date and asks ‘What’s so important?’, I totally get that. To introduce a romantic and/or sexual relationship now, after two series, would be more upsetting for me than the arrival of Mary, John marrying her, and the subsequent change this will necessitate in John and Sherlock’s relationship. It would rob me of the one character on television that feels the same way I do. I’m glad Mary is arriving, because although we have the reunion to deal with, the show would otherwise just end up going back to being essentially the same set up of John and Sherlock living together and solving crimes. Now there’s going to be a new dynamic and I can’t wait. I want to know how Sherlock develops and accommodates Mary being part of John’s life, given he was dead, and how John balances his relationship with Mary with the return of Sherlock, and all the rest of the wonderful scenes that are coming our way. So, I know many of the Johnlockers that wanted to see it become canon are upset, but I’m happy, I’m excited and the ship hasn’t sunk for me, because that’s what fanfic is for.
Apologies in advance, I’ve written this quickly and I’ve found that I usually end up saying something in not quite the way I intended it.
