This thread made me realize…maybe that disembodied hand with a gun, the one that kills Emelia as she requests, maybe that’s just another clue that Mary helped Jim fake his death.
Because okay. Emelia can be a mirror for Mary, Jim, and/or Sherlock. The way she kills herself is similar to the way Sherlock tells Anderson he faked his death, but Sherlock is supposed to be using her to figure out how JIM faked HIS death. It makes sense that Sherlock would conflate the two incidents. I am you. You or me?
Molly helped Sherlock fake his death, and as others have pointed out, “Mr. Hooper” could have left the bride’s message on the walls of the mortuary and then put the gun in Emelia’s mouth when the time came. Another conflation. He would’ve needed a confidante. But then, why not just show that it was MP!Molly? Why this?
Emelia could have put that gun in her mouth herself. Like Jim did. Why this hand? Who is it attached to?
I’ve written before about Sherlock using this simulation to figure out the truth about Mary, how he first imagines her working for Mycroft despite KNOWING that Mary left the CIA to go freelance, how he imagines her saying she’s a part of the women’s suffrage movement and is so damn clever and is neglected by her husband yet is NOT part of this uber-clever lady cult that she is inexplicably able to track down on her own? Bullshit. She’s a part of it. I’m sure she’s just visiting with friends. John’s always right.
I think the above gif might be further evidence to the theory that Mary is both Moran and Moriarty. If Moriarty is more than a man, an organization –– if this is indeed a Dread Pirate Roberts situation –– then Mary was second-in-command at the pool and on the roof. And now maybe she’s taken over. Once (s)he had risen, anyone could be him/her. From confidante to mastermind.
And what the hell, I’ll throw this out there too. If John really is right about the twins, a secret twin, well, maybe that explains why Emelia says “Swiftly, now. No tears.” Killing your twin would be hard, even if you’re both murderous psychopaths.
