John: Go after her and apologize.
Sherlock: Apologize?
John: Um-hmm.
Sherlock: Oh, John, I envy you so much.
John: You envy me?
Sherlock: Your mind, it's placid, straightforward, barely used. Mine's like an engine, racing out of control, a rocket tearing itself to pieces, trapped on the launchpad. I need a case!

Sherlock: Phone Lestrade. Tell him there's an escaped rabbit.
John: You serious?
Sherlock: It's this, or Cluedo.
John: Ah, no. We are never playing that again.
Sherlock: Why not?
John: Because it's not actually possible for the victim to have done it, Sherlock, that's why.
Sherlock: It's the only possible solution.
John: It's not in the rules.
Sherlock: Then the rules are wrong!

Henry Knight: Do you know Dartmoor, Mr. Holmes?
Sherlock: No.
Henry Knight: It's an amazing place. It's like nowhere else. It's sort of... bleak, but beautiful.
Sherlock: Hmm, not interested. Moving on.
Henry Knight: We used to go for walks after my mum died, my dad and me. Every evening we'd go out on the moors.
Sherlock: Yes, good, skipping to the night that your father was violently killed, where did that happen?

Henry Knight: How on earth did you notice all that?
John: It's not important...
Sherlock: Punched out holes where your ticket's been changed...
John: Not now, Sherlock.
Sherlock: Oh, please. I've been cooped up here for ages.
John: You're just showing off.
Sherlock: Of course. I am a show-off, that's what we do.

Sherlock: What did you see that changed everything?
Henry Knight: It's a strange place, the hollow. Makes you feel so cold inside, so afraid.
Sherlock: Yes, if I wanted poetry, I'd read John's emails to his girlfriends. Much funnier. What did you see?

Sherlock: Nice touch.
John: I haven't pulled rank in ages.
Sherlock: You enjoyed it.
John: Oh yeah.

Sherlock: I never did ask, Dr. Frankland, what exactly is is it that you do here?
Dr Frankland: Oh, Mr. Holmes, I would love to tell you. But then, of course, I'd have to kill you.
Sherlock: That would be tremendously ambitious of you.

John:: So?
Sherlock: So?
John: What was all that about the rabbit? Oh, please, can we not do this this time?
Sherlock: Do what?
John: You being all mysterious with your cheekbones and turning your coat collar up so you look cool.
Sherlock: I don't do that.
John: Yeah you do.

Sherlock: The question is, has she been working on something deadlier than a rabbit?
John: To be fair, that is quite a wide field.

Sherlock: Look at me. I'm afraid, John. Afraid.
John: Sherlock...
Sherlock: I've always been able to keep myself distant. Divorce myself from feelings. But you see, body's betraying me. Interesting yes. Emotions. Grit on the lens, the fly in the ointment.
John: All right, Spock, just take it easy.

Sherlock: I uses my senses, unlike some people. You see, I am fine. In fact, maybe better. So just leave me alone.
John: Yeah. Okay. Okay. So why would you listen to me? I'm just your friend.
Sherlock: I don't have friends.
John: No. Wonder why.

Sherlock: How about Louise Mortimer? Did you get anywhere with her?
John: No.
Sherlock: Too bad. Did you get any information?
John: Hm. You're being funny now.
Sherlock: I thought it might break the ice a bit.
John: Funny doesn't suit you. I'd stick to ice.

Sherlock: Murder weapon, scene of the crime, all at once. This case, Henry... thank you. It's been brilliant.
John: Sherlock.
Sherlock: What?
John: Timing.

John: All right, Spock, just take it easy.
