Sherlock, Series 1

John:
There are lives at stake, Sherlock! Actual human live- Just, just so I know, do you care about that at all?

Sherlock:
Will caring about them help save them?

John:
[angrily] Nope!

Sherlock:
Then I'll continue not to make that mistake.

John:
And you find that easy, do you?

Sherlock:
Yes, very. Is that news to you?

John:
No. [pause] No.

Sherlock:
[realising] ...I've disappointed you.

John:
[sarcastically] That's good, that's good deduction, yeah.

Sherlock:
Don't make people into heroes, John. Heroes don't exist, and if they did, I wouldn't be one of them.
