Cops brought her home. She and some friends broke into a store, tried on some dresses last night, lit up the breathalyzer like a Christmas tree.

Diggle [about Thea]

Diggle: You really did lose your mind on that island.
Oliver: Found a couple of things along the way.
Diggle: Like what archery lessons?
Oliver: Clarity.

You were born with a platinum spoon in your mouth Queen, what'd you spend five years on an island without room service and suddenly you found religion?

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.

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.

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

Oliver: If we're gonna do this, it has to be about Tommy. I need to be the man he hoped I could be. Now you two have helped me take the first step.
Felicity: So what's step two? I'm game for anything as long as it doesn't involve skydiving, and I'm pretty down on landmines now, too.
Oliver: The city still needs saving, but not by The Hood. Not by some vigilante who's just crossing names off a list. It needs something more.
Diggle: It needs a hero, Oliver.
Felicity: It's too bad The Hoods kind of ruined your nickname.
Oliver: No, it's good. I don't want to be called The Hood anymore.
Diggle: Okay. So what do you want to be called?

I would have emailed, but this isn't exactly an email hot spot.

Healthcare has enough problems without you punks.

Diggle: You know I was just about to make my move on her. I didn't need one of your trick arrows getting in the way.
Oliver: I couldn't risk it. Where would I be without my black driver.

Oliver: I got wrapped up in my own suffering and I forgot that some other people might be suffering, too.
Diggle: You know, we're getting dangerously close to hug territory, so I'm gonna fall back.

Oliver, what I would like to know is what you were doing at Laurel's office in the first place. She makes you public enemy number one and you figured this was a good time to chat?

Arrow Quotes

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

Diggle

She was my sister. I couldn't be angry because she was dead. I couldn't grieve because I was so angry, that's what happens when your sister dies while screwing your boyfriend.
