Diggle: What did you want?
Felicity: Is that any way to treat a girl who just walked up six flight of stairs?
Diggle: No, it's not. Welcome.

Oliver: Do you want Lauton arrested?
Diggle: No.

Then let's talk about Helena. Oliver, if you didn't still have feelings for this girl you would have thought of a different solution than letting her extort you into killing someone.

Felicity: Where are we going to get our hands on a rare Spanish antiquity?
Diggle: You really have no idea how rich his family is, do you?

Diggle: Oliver, if this were anybody else you'd be hooded up right now on your way to have an Arrow side chat with them.
Oliver: This isn't anybody else. This is my mother, and I know her.

Diggle: Woah. That's a neat trick. You gonna teach me that someday?
Oliver: No.

Diggle: Find what you're looking for?
Oliver: Took down three Vertigo pushers tonight, Diggle. Last one finally knew a name. The Count.
Diggle: The Count. That's worse than The Hood.

I thought you took that book off your father's dead body. How could he have been so chatty?

So Laurel's on her own against a murderer who burns people alive?

They need the man in the hood.

So is this guy trying to frame you or call you out?

You're like a dope fiend who thinks he can deal with his own addiction by making another addict go straight.

Diggle [to Oliver]
