That last look: it’s a secret between the two of them, that Sherlock cares and has feelings— a piece of himself he’s been able to make everyone uncertain about— except apparently Jim Moriarty, who tells him playfully that he alone can see everything in Sherlock’s heart.
It’s quite an intimate character insight, especially given that John’s questioned it (“just so I know, do you actually care about them at all?”) earlier in the episode
“you’re me” necessarily implies “turns out I may have a heart too”
I am not sure if this is already an accepted head canon or what, but it is something I have believed since I first saw Reichenbach.
“Let me give you a little extra incentive. Your friends will die if you don’t.”
“Oh not just John. Everyone.”
Moriarty was real.
I am making a Sherlock themed magazine called what else? “The Sherlockian” I’ll share it when it’s finished! Yay!
Suddenly, I’m Mr Sex.
