Dr. John Watson: I'm definitely going to kill you.Sherlock Holmes: Oh, please. Killing me, that's so two years ago.
A nice murder. That will cheer you up.
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.
I mean, obviously, "normal" and "fine" are both relative terms when it comes to Sherlock and Mycroft.
