I always remember what John said on his blog: “I could see the look in Sherlock’s eyes - a flash of, not anger, but hurt. For a second, he looked like a little, lost child”. You can see that he’s touched, not because for a second he thought John was behind this, because fucking Moriarty found his only weakness, John.
And he’s threatening John and that’s not acceptable.
There’s no game here, not anymore.
