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!

Mary

Sherlock: I'm scared of dying.
Culverton: You wanted this.
Sherlock: I have reasons
Culverton: But you don't actually want to die.
Sherlock: No.
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

John: Whose car is that?
Mrs. Hudson: That's my car?
John: How can that be your car?

Sherlock

Mycroft: I get regular updates.
Lady Smallwood: And?
Mycroft: Sherrinford is secure.

"Faith": Big brother is watching you.
Sherlock: Literally.

Sherlock: Chips
"Faith": Chips?
Sherlock: You're suicidal, you're allowed chips. Trust me, it's the only perk.
