Dr. John Watson: "You didn't kill Mary. Mary died saving your life. It's her choice. No one made her do it, no one could ever make her do anything, but the point is, you did not kill her."
Sherlock Holmes: "In saving my life she conferred a value on it... It is a currency I do not know how to spend."
"Every great cause has martyrs. Every war has suicide missions and make no mistake, this is war. One half of the human race at war with the other. The invisible army hovering at our elbow, tending to our homes, raising our children. Ignored, patronised, disregarded. Not allowed so much as a vote. But an army nonetheless, ready to rise up in the best of causes. To put right an injustice as old as humanity itself. So you see, Watson, Mycroft was right. This is a war we must lose."
