Andrew died because he knew me. I don't know what else there is to say.

Watson

Bell: Where did you find this? CSU was in there and they didn't find anything.
Holmes: They failed to examine the zebra droppings.

You don't understand. I'm saying what I need to do is commit myself to this work completely. The best place for me to do that is here. I want to come back to the brownstone.

Watson

Watson: Do you want me to live here or not?
Sherlock: I do. I have never wavered on that.

I worried in the aftermath of trauma that you might be ... overadjusting. That moving back might not be the progression you believe it to be, but it might be a regression, a retreat into the safety of the known. I suppose I just wanted to be sure that I hadn't been too quick to encourage. That I haven't unwittingly cast myself in the role of an enabler.

Sherlock

I mean ... it really comes down to just this, Mrs. Powell. What do you think you deserve?

Sherlock

A real moving company will step foot in our brownstone over my mouldering body.

Sherlock

This is not a consultation. This is an interrogation.

Sherlock

The unfortunate truth is, however improbable certain things may be in respect to this crime, nothing is impossible.

Sherlock

Let's adhere to our sunniest theory, shall we? My note to Maria Gutierrez was not an invitation to murder, but an agreement to lend my help as a detective. What if she knew she was in danger? What if I missed something my sober self would have observed in an instant that might have saved her life? Would you still consider my hands blood-free?

Sherlock

Sherlock: You don't know him. You never met him.
Watson: So now you're Dr. Jekyll and he's Mr. Hyde?

Watson: How do you do it, guess things?
Sherlock: I observe and then I deduce.
Watson: How did you know I was a doctor, you said you could tell from my hands.
Sherlock: Hand, singular. It was soft no calluses.
Watson: How did you know my father had an affair?
Sherlock: Google. Not everything is deducible.
