Sherlock: Why don't I remember her?
Mycroft: You do remember her, in a way. Every choice you ever made, every path you ever taken. The man you are today is your memory of Euros.
John: So there were three Holmes kids. What was the age gap
Mycroft: 7 years between myself and Sherlock, one between Sherlock and Euros.
John: Middle child, explains a lot.
Mycroft: For God's sake, this is not one of your idiot cases.
John: You might want to close that window. There is an east wind coming.
Mycroft: So that's it, is it? You're just going.
John: Well don't worry! There's a place for people like you, desperate, terrified, the ones with nowhere else to run.
Mycroft: What place?
John: 221B Baker street. See you in the morning. If there's a queue, join it.
Mycroft: Doctor Watson, why would he do that to me, that was insane!
John: Yes, well, someone convinced him that you wouldn't actually tell the truth unless you were actually wetting yourself.
John: Probably me.
John: You did not kill Mary. She made a choice to save your life. You didn't make her do it, nobody could make Mary do anything. You didn't kill her.
Sherlock: In saving my life she conferred a value on it. It is a currency I do not know how to spend.
Culverton: I'm gonna be so famous.
Lestrade: You're already famous.
Culverton: Yeah, but with this I could break America!
The only way to save John is to make him save you.Mary
Sherlock: I'm scared of dying.
Culverton: You wanted this.
Sherlock: I have reasons
Culverton: But you don't actually want to die.
Culverton: Good. Say that for me.
Sherlock: I don't want to die.
Get out of my house, you reptile.Mrs. Hudson
Culverton: How do you catch a serial killer?
Sherlock: Same way you catch any killer.
Get over yourself. You're not my first smackhead, Sherlock Holmes.Mrs. Hudson
