INTERVIEWER: Who is the lonelier character — Doctor Who's Doctor, or Sherlock?
MOFFAT: I think the Doctor, because the Doctor actually does crave company; I don’t think Sherlock really does.
I think people get under his skin—and I think possibly without him even realising—so John, and Mrs. Hudson, definitely. He’s very fond of her.
And he’s actually terribly fond of Lestrade—he doesn’t know it yet, but he is. I think he got to [Sherlock] in a way he hadn’t been got to before. It just sort of happened. And it happened in the stories, too.
Sherlock wants to be a calculating machine, but he really isn’t. He really, absolutely, properly isn’t.
He’s a quite a moody, difficult, emotional man, is the truth—even in the original.
And it’s really fascinating to read the real Doyle, and you realise: if [Sherlock] thinks a man has wronged a woman, he’s dragging a riding crop off the wall to beat him up, ‘cause he’s so angry.
He’s actually not at all cold and aloof, he just wants to be and presents that way. But he isn’t—he isn’t at all.
But he would like to be.
