James Moriarty

— You know, when he was on his deathbed, Bach, he heard his son at the piano playing one of his pieces. The boy stopped before he got to the end.
— The dying man jumped out of bed, ran to the piano and finished it.
— Couldn't cope with an unfinished melody.

Episode 3

— Is that the British Army Browning L9A1 in your pocket, or are you just pleased to see me?
— Both.

— You've come the closest. Now you're in my way.
— Thank you.
— Didn't mean it as a compliment.
— Yes, you did.
— Yeah, OK, I did.

— You are insane!
— You are just getting that now?

I just like to watch them all competing. "Daddy loves me the best." Aren't ordinary people adorable? Well, you know, you've got John. I should get myself a live-in one.

— I can prove that you created an entirely false identity.
— Oh, just kill yourself. It's a lot less effort.

No such things as secrecy. I own secrecy. Nuclear codes? I couid blow up NATO in alphabetical order.

— You... You never felt pain, didn't you? Why did you never feel pain?
— You always feel it, Sherlock. But you don't have to fear it! Pain...heartbreak...loss...death...it's all good. It's all good.<...>
It's raining, it's pouring, Sherlock is boring. I'm laughing, I'm crying, Sherlock is dying. Come on, Sherlock. Just die, why can't you? One little push and off you pop. You're going to love being dead. No one ever bothers you.

Falling is just like flying, except there's a more permanent destination.

That's your weakness. You always want everything to be clever.

— Those digits are meaningless. They're utterly meaningless. You don't really think a couple of lines of computer code are going to crash the world around our ears? I'm disappointed in you, ordinary Sherlock.
— But the rhythm...
— Partita no 1! Thank you Johann Sebastian Bach.
