Not in the cards bc Joan WILL SHOW UP, but if she didn't it would basically go like: John still claiming to be firmly heterosexual but Sherlock is his OG, man, so he's going to resist that temptress all over the place. But now Sherlock is competing for his affections too, and they're both terrible at it. And John has to let them both down gently. Or I guess you can put on your slash-goggles and make it gay or OT3.
I had a short-joke planned with Moriarty. (since he's a bit shorter than John that means he's STILL shorter than this fem!Sherlock) BUT I MEAN REALLY SHORT JOKES? And Joan will def make an appearance, I can't torture John for too long
