Sherlock: "You're a doctor. In fact, you're an army doctor."
Watson: "Yes."
Sherlock: "Any good?"
Watson: "Very good."
Sherlock: "Seen a lot of injuries then. Violent deaths."
Watson: "Well, yes."
Sherlock: "Bit of trouble too, I bet?"
Watson: "Of course. Yes. Enough... for a lifetime, far too much."
Sherlock: "Want to see some more?"
Watson: "Oh God, yes."

Anderson: "So we can read her emails, so what?"
Sherlock: "Anderson, don't talk out loud. You lower the IQ of the whole street."

Sherlock: "Shut up."
DI Lestrade: "I didn't say anything."
Sherlock: "You were thinking. It's annoying."

Anderson: "Never mind that. We found the case. According to 'someone', the murderer has the case and we found it in the hands of our favorite psychopath."
Sherlock: "I'm not a psychopath, Anderson. I'm a high-functioning sociopath. Do your research."

Watson: "Have you talked to the police?"
Sherlock: "Four people are dead, there isn't time to talk to the police."
Watson: "So why are you talking to 'me'?"
Sherlock: "Mrs. Hudson took my skull."
Watson: "So I'm basically filling in for your skull?"
Sherlock: "Relax, you're doing fine."

Sherlock: "I'm a consulting detective. The only one in the world. I invented the job."
Watson: "What does that mean?"
Sherlock: "It means whenever the police are out of their depth, which is always, they consult me."

Watson: "That... was amazing."
Sherlock: "You think so?"
Watson: "Of course it was. It was extraordinary. It was quite extraordinary."
Sherlock: "That's not what people normally say."
Watson: "What do people normally say?"
Sherlock: "'Piss off!'"
