Malcolm: John?
Diggle: My friends call me Dig. You? Shouldn't even talk to me.

Do you remember what you told me? It takes a monster to kill a monster.

Flashback Oliver

Tommy: I'm sorry.
Oliver: No, don't apologize.
Tommy: I was angry and I was jealous. I am my father.
Oliver: No, no you're not.
Tommy: Did you kill him?
Oliver: No.
Tommy: Thank you.

Okay, can you please stop. You're worse than a shipper on a soap opera.

Felicity

You know when we first tried to get off this island it was as strangers; but now it's as brothers.

Slade

Oliver: I need to believe that no matter what happens in our lives, no matter how much darkness infects us, I need to believe we can come back from that!
Diggle: It was exactly that thinking that led you to the League last year. It doesn't seem like you learned much from that.

I'm giving up a lot so maybe I thought the universe owed me one.

Oliver

Maseo: What were you thinking? Anyone at that party could have seen you.
Oliver: Yeah, I pulled the hoodie down over my face.
Maseo: That disguise wouldn't work even if you smeared greasepaint over your face.

Barry: You tortured that guy.
Oliver: I interrogated him.
Barry: When my friends said that you were a criminal, I defended you because I thought you were supposed to be a hero. I thought we were supposed to be better than them.
Oliver: Barry, you live in Central City, where it's sunny all the time and your enemies get cute nicknames. You're not in Central City. I live in the city where my best friend was murdered. Where a woman I loved was shot full of arrows and sent tumbling off of a rooftop, where my mother was murdered right in front of me, so before you...
Barry: My mother was murdered right in front of me, too. But I don't use my personal tragedies to just torture whoever pisses me off.
Oliver: Well I'm sorry, Barry, but I'm not as emotionally healthy as you are.

Slade: That's a particularly firm handshake you have there son.
Roy: Yeah, you too.

Laurel: You look handsome!
Tommy: I try not to, it just keeps happening.

Felicity: What are you doing there?
Curtis: I know, right? I'm still pinching myself.

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.

Laurel
