magnussen and sherlock both tried to stop mary by reminding her of what john might think of her actions, sherlock even called mary ‘mrs watson’ aka ‘you’re john’s wife, you are married to the most wonderful human being and we both know it, think of john, don’t do this’ and instead of accepting sherlock’s help (which in any other tv shows would have shown to the audience that she had still good intentions and was intended to be seen as a complexed and layered ‘good’ character and not an antagonist), she shot him
by shooting sherlock after sherlock reminded her that killing him would break john’s heart AGAIN, she basically proved to the audience that she didn’t care about john’s feelings
The thing that irritates me most about the “Sherlock is abusive because of what he did in the train car” thing is that it stems from a fundamental misunderstanding of John Watson’s character as developed across the previous six episodes. This is a guy who struggled to tell Sherlock how he felt about him when he was completely alone and speaking not to Sherlock but to an inanimate gravestone, literally a hunk of marble, and you think it would be in-character for John to speak aloud the words “I forgive you” (which he needed to say and which Sherlock needed to hear) to the real live Sherlock without the urgency of an imminent explosion?
Not only John, but in fact both of these characters are so emotionally constipated, and have been so consistently developed as such, that a bomb fake-out was the minimum required to break the ice between them and get them all relaxed and happy around each other like they were in, y’know, the scene immediately following the train car. The John Watson we know was never in a million years gonna sit down and talk that one out without the aid of huge amounts of adrenaline, which Sherlock provided. He and Sherlock had tried having a normal-person conversation earlier in the episode. It didn’t melt the ice. The issue was too big for a normal-person conversation. Which is lucky for them, considering that neither of them is “normal” and that they exist not in the real world, in which a bomb fake-out would be unthinkable, but in a fictional world of Adrenaline Junkies and the People Who Love Them in which one person says “We’re gonna die! Haha, psych,” and the other reacts with “Oh, you got me there, you lovable scamp. Shucks, I just can’t stay mad at you.”
I roll my eyes into the back of my head every time someone tries to talk about the real-world morality of John forgiving Sherlock in that scene when the thing that John is forgiving him for is faking his death to take down the vast shadowy network of a criminal mastermind, a.k.a. a scenario so outlandish that we left the “real world” behind well over two years ago.
I mean, it’s all well and good for you to say that you would never do such a thing to your best friend, but I bet you’ve never had to fake your death by jumping from the roof of a hospital while snipers were training their laser sights on your only three friends in the world, then disappear to work as an underground operative for two years, only to resurface in the clutches of your Diabolical Archenemy’s actual henchmen in a remote location in Serbia, from which you were rescued by your genius MI-6 brother who learned the Serbian language in less than a day, have you?
Well they were chatting about “adult films” Malkovich gamely went off on a tangent about how forbidden sexuality can be in most movies, and how verboten it was to show something onscreen as innocent as “a thigh or upper arm.” Cumberbatch misheard the latter. “Other arm?” “
"Other arm" is a pun for penis. There’s a saying "his third leg" - penis (a big one LoL.. run!) So it is similar saying.
"Do you want to ask another question? Ask what my shoe size is."
"What’s your shoe size?" asked the fan, to more shrieks.
Cumberbatch grinned. “It’s a whole other arm.”
You’ve probably heard what they say about guys with large feet? Their supposed large dicks. The ‘arm’ is already a dick here so he’s just having one.. little… penis joke.
