Sherlock’s facial expressions in His Last Vow (Part - 1)
This is killing me every time. I want to know exactly what was going on in his mind, there. Did he really think of something to say to express his feelings to John? What statements did he briefly consider before discarding them? And how fucking horrible must it have felt to want to say it, want to find the right words but being unable to (for whatever of the many possible reasons)? Only to come up with a joke then, just to see John smile one last time.
LEAVE ME THE FUCK ALONE.
