Sherlock - Season 4

"Is Molly the right person to be doing medicals? She's more used to dead people."

"I mean, obviously, 'normal' and 'fine' are both relative terms when it comes to Sherlock and Mycroft."

"I'm not sweet, I'm just high."

Police Officer: "Do you have any idea at what speed you were going?"
Mrs. Hudson: "No, of course not, I was on the phone!"

"Stop talking. It makes me aware of your existence."

"There must be something comforting about the number three, people always give up after three."

Faith: "Oh... big brother is watching you."
Sherlock: "Literally."

"Taking your own life... Interesting expression. Taking it from who? Once it's over, it's not you who'll miss it. Your own death is something that happens to everybody else. Your life is not your own, keep your hands off it!"
