If you're going to wallow you have to do it in the privacy of your own room.

Sherlock

My name is Moriarty. I believe we're overdue for a chat

Moriarty

These locks, you put them in some special order the other day, right? [Knocks over locks] Do it again.

Joan

Watson: I notice you don't have any mirrors around here.
Holmes: What is that supposed to mean?
Watson: That you know a lost cause when you see one.

Sherlock: What are you doing?
Watson: Depriving you of all stimuli; time for you to get some sleep.
Sherlock: What? No, no. Right after you solve a case, you're flushed with a success. We should double down with work.
Watson: We?
Sherlock: You, me, Angus, some combination of the three. You already know I favor you.

I'm in a hurry. Shall I select your undergarments as well?

Holmes

Sherlock: This is personal
Joan: I could say the same thing.

Joan: As someone once said, once you eliminate the impossible, whatever is left, no matter how improbable, must be the truth.
Sherlock: Sounds like a windbag.

Sherlock: She died.
Watson: Irene?
Sherlock: We were quite close, I did not take her passing well.

Sherlock: Bit of a letdown actually, I think I could have gotten 20 times my normal rate.
Watson: What is your normal rate?
Sherlock: Oh. I don't have one, remind me to make one up before we leave.

Sherlock: We can tell my father I've hit a bit of a rough patch...
Watson: I took a new job this morning. I'll be starting next week after you and I wrap up.
Sherlock: I see... I'm usually quite good with deductions.
Watson: You okay?
Sherlock: My dear Watson, when ever am I not?

You're the smartest man I know..... [No response from Sherlock] Waiting for you to chime in and say that's ridiculous.

Joan
