John: Whose car is that?
Mrs. Hudson: That's my car?
John: How can that be your car?

Lady Smallwood: Do you still speak to Sherrinford?
Mycroft: I get regular updates.
Lady Smallwood: And?
Mycroft: Sherrinford is secure.
"Faith": Big brother is watching you.
Sherlock: You're suicidal, you're allowed chips. Trust me, it's the only perk.
Culverton Smith: What's the very worst thing you can do to your very best friends?
Faith: Well? What is the worst thing you could do
Culverton Smith: Tell them your darkest secret. Because, if you tell them, and they decide they rather not know, you can't take it back, you can't unsay it. Once you've opened your heart, you can't close it again.

Sherlock: If you ever think I'm becoming full of myself, overconfident or cocky, would you just say the word "Norberry" to me, would you?
Mrs Hudson: Norberry?
Sherlock: Just that. I'd be very grateful.
Mycroft: Is that sentiment talking?
Sherlock: No, it's me.
Mycroft: Difficult to tell the difference these days.
Mycroft: Looks very fully functioning.
Sherlock: Is that the best you can do?
Mycroft: Sorry, I've never been very good with them.
Sherlock: You two, take a bus.
Sherlock: Because I need to concentrate and I don't want to hit you.
