SHERLOCK: I'm not a psychopath, Anderson.

SHERLOCK: Shut up.
LESTRADE: I didn't say anything. SHERLOCK:

JOHN: Why didn't I think of that.
SHERLOCK:

SHERLOCK: Oh what now? I'm in shock!

JOHN: I didn't get the shopping.
SHERLOCK: What? Why not? JOHN:

SEBASTIAN: Twice round the world in a month, correct. Are you going to say I've got a special type of ketchup on my tie you can only get in Manhattan? The mud on my shoes?
SHERLOCK:

JOHN: It's where two people who like each other go out and have fun?
SHERLOCK: That's what I was suggesting. JOHN:

SHERLOCK: I need to ask some advice.
JOHN: What? Sorry? SHERLOCK:

JIM: If you don't stop prying, I'll burn you. I'll burn the heart out of you.
SHERLOCK:

SHERLOCK: Homeless network. My eyes and ears all over the city. Absolutely indispensable.
JOHN: Oh! So, you scratch their back, and then... SHERLOCK:

SHERLOCK: Catch. You. Later.
JIM:

JOHN: But it's the solar system!
SHERLOCK: Oh hell, what does that matter?

MYCROFT: We are in Buckingham Palace, the very heart of the British nation.

MYCROFT: My brother has the brain of a scientist or a philosopher and yet her elects to be a detective. What might we deduce about his heart?
JOHN: I don't know. MYCROFT:

JOHN: Punch you?
SHERLOCK: Yes, punch me in the face! Didn't you hear me? JOHN:

JOHN: You flirted with Sherlock Holmes?
IRENE: At him. He never replies. JOHN: Oh, Sherlock always replies. To everything.

JOHN: Oh, you're being funny now?
SHERLOCK: I thought I'd break the ice a bit. JOHN:

SHERLOCK: Listen, what I said before, John, I meant it. I don't have friends.

HENRY: It's a strange place, Dewer's Hollow. Makes you feel so cold inside, so afraid.
SHERLOCK:

JOHN: What're you talking about, you're busy? You don't have a case! A minute ago you were complaining...
SHERLOCK:

JIM: In a world of locked rooms, the man with the key is king.

SHERLOCK: How long have I known him? Not really your best line of inquiry.

JOHN: You're doing a 'We both know what's going on'-face.
SHERLOCK: We do. JOHN:

SHERLOCK: I may be on the side of the angels.
