#joan watson and her personal valet
Seriously, I love this. Here’s the deal. Sherlock sometimes treats Joan like she’s lower than him, but it’s never because she’s a woman. It’s merely his ego about his own brilliance. Often he’s fascinated by the things that make her female, or make her more normal than he is. So Sherlock sometimes treats Joan like crap, but he also apologizes, and admits that he’s wrong. He’s also starting to realize how much of an asset Joan is.
On top of all that, Joan’s gender has never become an issue in their dynamic. She’s still sassy and strong, and he can be very courteous to her. And then sometimes he’s a dick, of course.
But, in no way does Sherlock’s chivalry ever force Joan to be a) feminine, b) submissive or c) both. Never does Joan’s acceptance of his chivalry make her a lesser party. Instead, his chivalry is just what it should be, a nice gesture that can be appreciated but in no way implies that she or he is of a “traditional” mentality.
