The experience of helping others it its own reward.

Laurel

I've been researching some of those people online and....they're not good people.

Oliver

I think this list might have cost Walter his life.

Felicity

Felicity: If it's an energy drink, why is it in a syringe?
Oliver: I ran out of sports bottles.

Vertigo is measured in lives. Fifty six people died to perfect this high. Believe me when I say that they did not die for nothing.

The Count

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.

Whoever you fear, fear me more!

Laurel: This clinic was his mothers.
Malcolm: Yes. And his mother taught him something that I've been trying to - that the world is a harsh and unforgiving place.
Laurel: And when did she teach him that?
Malcolm: When she was lying dead in the street with a bullet in her head. Good night.

Apparently he wants to mend some fences, but thanks to him I can't afford a fence, so I can only assume he has some other agenda.

Tommy

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

Diggle

I could be wrong. The list isn't.

Oliver

Arrow Quotes

Diggle: I see you brought your plus one.
Ray: Nice to meet you. Ray Palmer.
Diggle: John Diggle. [whispering into Ray's ear] You hurt her, they'll never find your body. [louder] Nice to meet you!

Felicity: What's going on? Ray?
Ray: Oliver Queen is the Arrow.
Felicity: What?
Ray: I have a 140 IQ and three PhDs, but it's pretty hard to insult my intelligence, but I'm pretty sure you just did. It all makes sense now. Your, ah, sudden disappearances, your apprehension of helping me with my mission. You've been working with the Arrow this whole time.
