Sherlock - Season 1

Watson: "So, when... when you say you're concerned about him, you actually are concerned?"
Mycroft: "Yes, of course."
Watson: "It actually is a childish feud?"
Mycroft: "He's always been so resentful. You can imagine the Christmas dinners."

Sherlock: "Who'd sponsor a serial killer?"
Jeff: "Who would be a fan of Sherlock Holmes?"

Watson: "Where did you get this? Detective Inspector Lestrade?"
Sherlock: "Yeah. I pickpocket him when he's annoying. You can keep that one, I've got plenty at the flat."

"Think! Who do we trust, even though we don't know them? Who passes unnoticed wherever they go? Who hunts in the middle of a crowd?"

"One thing about being a cabbie, you always know a nice quite spot for a murder. I'm surprised more of us don't branch out."

"I don't wanna kill you, Mr. Holmes. I'm gonna talk to ya, and then you're gonna kill yourself."

"Brilliant! Yes! Ah, four serial suicides and now a note, Oh, it's Christmas!"

Sherlock: "If you were dying, if you'd been murdered, in your very last few seconds, what would you say?"
Watson: "'Please, God, let me live.'"
Sherlock: "Oh, use your imagination!"
Watson: "I don't have to."
