[Season 3 opening]
Oliver Queen: My name is Oliver Queen, after five years in hell, I have come home with only one goal: to save my city. Now others have joined my crusade. To them, I'm Oliver Queen. To the rest of Starling City, I'm someone else. I am something else.
Nyssa al Ghul: I'm Nyssa, daughter of Ra's al Ghul. Heir to the demon.
Felicity Smoak: Felicity Smoak. M.I.T. Class of '09.
Felicity Smoak: It feels really good having you inside me... And by you I mean your voice. And by me I mean my ear. I'm going to stop talking. Right now.
Oliver Queen: That would be my preference.
Sebastian Blood: You know who he is under that hood, don't you?
Slade Wilson: I know exactly who he is. He's my friend.
Sebastian Blood: That's why you don't want him dead.
Slade Wilson: Death would be a release from this life, and his sentence has yet to be carried out.
[Season 4 opening]
Oliver Queen: My name is Oliver Queen. After five years in hell, I returned home with only one goal: to save my city. But my old approach wasn't enough. I had to become someone else. I had to become something else. I had to become the Green Arrow.
Ra's al Ghul: I was 11 years old when I killed my first man. I remember the look in his face when the light went out behind his eyes. Such a sudden change, almost imperceptible, between life and death. And I felt ashamed. I had stolen from that man the most precious gift of all - life. But I also felt something else - pride, because I had taken up arms against someone who sought to do ill against my family. And I realized what I had done was necessary. You see... I have replaced evil with death. And that... is what the league exists to do. And I have killed several thousand more men since then. And the world is better for it.
Oliver Queen: You've taken your last life.
Ra's al Ghul: No. You have lived your last day.
Quentin Lance: You're not exactly a hardened criminal, are you?
Felicity Smoak: No, I'm not any kind of criminal.
Quentin Lance: What do you call computer hacking?
Felicity Smoak: A hobby. That I do not engage in.
Slade Wilson: I'm going to tear everything he cares about away from him, destroy those who choose to follow him, corrupt those he loves. Once he has lost everyone and everything he values, I will drive an arrow through his eye.
John Diggle: What is this about, Malcolm?
Malcolm Merlyn: Well, this isn't going to be easy for all of you to believe.
Felicity Smoak: Because you're a sociopath and a liar.
Malcolm Merlyn: Be that as it may...
Malcolm Merlyn: There is nothing you can do to stop what is about to happen. And you shouldn't. This city needs what is about to happen in order to survive. The people who are destroying it from the inside need to be erased from the map.
Damien Darhk: Cities are like puppies. You see them writhing in agony on the street, you put them down. You don't let them suffer.
Prometheus: You're not a hero - you're a killer. And I'm going to show you that. I'm going to show you how everything you touch dies.
Damien Darhk: [at a City Council meeting] So you're all fretting about this city dying. I'm here on behalf of an organization that wants you to let it die. See, death is a beautiful thing. We die, we go into the ground, our remains grow into flowers. It's only in the interval after dying that new things can sprout.
[Season 7 opening]
