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."
