Joan: Joey wrote me a letter, telling me it wasn't my fault and that he forgave me.
Sherlock: This isn't the first time he's asking you for money.
Joan: He needed a car...

Tell me this … if he gets into trouble, who is going to help him?

Gregson

This is my sanctum sanatorium, did you honestly believe their wouldn't be any security measures?

Sherlock

Oscar: Wow. You're, like, cured now.
Sherlock: That's the dumbest thing I've ever heard you say. And I've known you for a long time.

I'm no closer to using today, than I was yesterday.

Sherlock

A junkie in the city is like a needle in a haystack. That's a job for Sherlock Holmes.

Oscar

Watson seems adequately sexed.

Sherlock

When you realize this is where you belong. In a place like this, Sherlock. WIth people like me. I was going to be there to watch you fall. Why do you keep fighting it, huh? Why put yourself through this? We both know it's just a matter of time. So why not just cut to the chase?

Oscar

It's just something that happened. It's in the past now. Let's just leave it there, shall we?

Kitty

[To Joan] I want to make sure Joey isn't taking advantage of you.

Sherlock

Bloom left an impression on me last night, not to mention some gray matter.

Sherlock

She's strong, Watson. Smart. The training I'm attempting to provide her, the same training I provided you, for her has an ulterior motive. It is, in part, an attempt to channel residual feelings that she has into a productive skill. I believe she will make an excellent investigator. Just not today.
