(1) Hi Jenna :) I don't know if you've ever talked about this, but I was watching TEH and I thought it was odd that, if Mary was truly one of the good ones and cared about John, she would have not gone to Sherlock to rescue John. I mean, she's clearly very

(2) I also found it strange that Mary didn’t kill CAM. Then I thought that it may have been because she knew Sherlock was gonna be there or because she didn’t know that the vaults were “not real” and she needed Sherlock and John to get the information from CAM. I also think that Sherlock figured this out, so this is why he didn’t kill CAM until there were witnesses and it was clear to everyone that the vaults were not real. This would make Mary feel safe and John wouldn’t be in danger.

(3) I’m done, I’m sorry, I needed to get that out of my system. Thanks for reading this, I hope you have a lovely day :)

Hi, aww thank you very much, I hope you’re having a lovely day, too!

Okay, here’s my thoughts…

1) Mary is a villain, through and through, as many, many believe. @inevitably-johnlocked has a great collection of posts on Mary here!

2) And this brings me to: “The Mary Problem” (phrase coined again by @inevitably-johnlocked). For me, the “problem” is that Mary has always been a villain, but the writers still partly wanted this to be a ‘big reveal’ moment for series 3. So…

3) They make Mary’s entire character misleading for a ‘rug-pull’ moment of shock for the audience when Mary turns around to face Sherlock with a gun in His Last Vow. The surface narrative initially tells us Mary can fit into John and Sherlock’s lives- she’s not fazed by anything, she actually ‘likes’ Sherlock, she can read a skip code…wait is that suspicious? oh, I’m sure it’ll be fine…

4) Of course, some fans worked out that Mary was a villain before His Last Vow aired- in some cases, even before Series 3 aired! See here and here for more info. In my case though, I was totally blindsided until the His Last Vow reveal- I feel for the writers’ tricks hook, line, and sinker! ;) Paraphrasing Moffat slightly from one of the episode commentaries here, I think I reacted this way because you’re so caught up in Sherlock’s return to John, you’re nervously tying yourself in knots hoping everything is going to go well- ironically, I was so focussed on John and Sherlock’s relationship, I at first ended up being unaware of the person who was/will be the biggest obstacle to their relationship!

5) Because Mary’s villainy was treated as a big Reveal Moment ( “You were told, but you didn’t listen,”), there are still some murky grey areas and confusion over her actual motivations, what’s really going on. Nothing is 100% as of yet when it comes to the devilish Miss Morstan. In my opinion, we’re still due some flashbacks, and yet more Big Reveals about what Mary’s been doing behind the scenes: (Feel free to add some more if you like, folks!

1) Mary was the sniper at the pool in The Great Game.2) Mary was there when Moriarty “shot” himself in The Reichenbach Fall.3) Mary shot the assassin who shook Sherlock’s hand in The Reichenbach Fall.4) Mary knew all about the planned skipcode and John being put in the bonfire- she is taunting Sherlock, revelling in how panicked he’s getting: “What does it mean?” she asks Sherlock re: the texts hinting about the bonfire. She knows exactly what she’s doing and is enjoying every minute of it…5) Mary was off doing Suspicious Things when she sent John and Sherlock off on a case in The Sign of Three.6) Parts of the confrontation with CAM were a set up.7) She received some sort of signal to wait until Sherlock arrived before encouraging John to propose at the restaurant in The Empty Hearse. (That’s why she left the table and makes her dramatic entrance down the staircase).
