I agree with lots of opinions I’ve seen on tumblr that His Last Vow was a frustrating episode in many ways, with some logical problems, odd characterization choices, and just plain lack of awesome writing. However, a fairly large part of my brain doesn’t want to jump all over the problems but to rejoice in the possibility of fanfic about Mary Morstan Watson, Semi-Reformed(?) Spy/Assassin and her adventures with her BAMF blogger husband and their friend the genius detective.
-I want exciting fic with Team Watson infiltrating a hideout of evildoers to rescue kidnapped Sherlock. What a pair of BAMFs.
-I want fluffy domestic fic where John and Mary move into the second bedroom of 221B. Mary and Sherlock get into arguments about whether his experiments or her weapons collection are more of a potential child safety hazard. Mary and John can alternate nights for who goes out with Sherlock to solve crimes and who stays home with the wee Watson.
-I want all the Sherlock/John/Mary fic. All of it. Dark, light, kinky, vanilla, angsty, happy, canon-compliant, utterly rejecting canon…it’s all fine. Bonus points for all three of them dancing or fic where they all have sex in totally inappropriate locations like in a criminal’s house that they’ve just broken into.
-I want Mary teaching Molly self-defense. Femslash optional.
-On the subject of femslash, I want Mary/Irene and Mary/Anthea. I need this because of reasons.
-I want angsty fic from Mary’s POV about the difficulty of leaving her past behind despite how very much she wants to, and the slow, painful process of reconciling with John.
-I want Avengers crossover fic where it turns out that Magnussen didn’t get to the bottom of Mary’s secrets, because before she joined the CIA she was a defector from the Soviet Union, trained alongside Natasha Romanov in the Red Room. Natasha and Mary still go out for drinks once a year.
-It’s not my headcanon, but I still want to read fic where Mary was Moriarty’s evil henchperson, provided she is written with as much authorial fondness as authors usually bestow on male fan-created versions of Col. Moran.
-I want Mary and Sherlock friendship fic where they work through the trust issues resulting from her very nearly killing him but continue to bond over their mutual devotion to John Watson.
-I want A.G.R.A. backstory.
-Mary Watson flips out when some rival with a grudge and a weapon breaks into her flat and she has to deal with him, causing her to accidentally burn the bread she was baking.
-AU fic where Mike Stamford introduced Sherlock to Mary Morstan as a potential flatmate instead of John.
-Mary fucking Watson née Morstan née AGRA, HBIC.
I want all of this and all the other Mary fic I’m not thinking of at the moment. Of course there’s things that displeased me about the way canon handled her character, but that just increases my desire to read fic. Because my feelings for Mary Morstan Watson are basically:
Yes. Yes to all of this. Yes times a million.

Well we know what series four will be like then
