I know exactly how this brotherhood works and right now it works for me.

Oliver

You cannot die until you have suffered the same way that I have suffered, until you have known complete despair -- and you will. I promise.

Slade

Five years ago I made a promise. Do you remember? Well I'm here to fulfill it. See you around kid.

Slade

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

Sara: He has the Mirakuru in him
Roy: So do I.
Sara: Can I trust you?
Roy: I'll be fine.

Diggle: Who is that?
Sara: His name is Slade Wilson and unless we stop him he's going to kill Oliver and his entire family.

I believe that when we lose someone we love that we have the obligation to honor it.

Slade

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

Slade

Moira: What should we drink to?
Slade: To friendship.

Slade: You and I have something in common.
Moira: What's that?
Slade: I know how difficult it is to pick yourself up when other people have written you off.

Because of the life that I lead, I just think it’s better to not be with someone that I could really care about.

Oliver

Because I realized that, that I went on that boat with you, too. And I've been slowly drowning for all of these years and after every heartbreak or setback or loss, I sank deeper into the dark water. And so when I saw you, so beautiful and so alive, I realized that I'm not those things. Not anymore. So please, please don't hate me Sara. Please.

Laurel

Arrow Quotes

You know Oliver, somebody once told me that secrets have weight. The more you keep, the harder it is to keep moving.

Diggle

Ra's al Ghul: You tasted death and you wanted more, but the truth is everyone and everything must come to an end. Even for one such as me.
Oliver: Kill me, but spare John Diggle's life. Let him go. I will beg for it.
Ra's al Ghul: You have shown tremendous strength, fortitude, power. No, Mr. Queen. I don't want to kill you. I want you to take my place. I want you to become the next Ra's al Ghul.
