John Watson

Sherlock: You’re a doctor. In fact you’re an army doctor.
John: Yes.
Sherlock: Any good?
John: Very good.

When the police are out of their depth, which is always, they consult me.

#3, Amy’s choice (5x07)

John: What am I doing here?
Sherlock: Helping me make a point.
John: I’m supposed to help you pay the rent.
Sherlock: Yes, but this is more fun.
John: Fun? There’s a woman lying dead.

#25, Unaired pilot

John: So why do you put up with him?
Lestrade: Because I’m desperate, that’s why.

Lestrade: I’m breaking every rule letting you in here.
Sherlock: Yes. Because you need me.
Lestrade: Yes I do. God help me.

Sherlock: Where?
Lestrade: Brixton, Lauriston Gardens.
Sherlock: What’s new about this one? You wouldn’t have come to get me if there wasn’t something different.
Lestrade: You know how they never leave notes?
Sherlock: Yeah.
Lestrade: This one did. Will you come?
Sherlock: Who’s on forensics?
Lestrade: Anderson.
Sherlock: Anderson won’t work with me.
Lestrade: Well, he won’t be your assistant.
Sherlock: I need an assistant.
Lestrade: Will you come?
Sherlock: Not in a police car. I’ll be right behind.
Lestrade: Thank you.
