Diggle

Roy: You’re the only thing keeping me together. How did I get to be so lucky?
Thea: You stole my purse.

Laurel, if there’s something on your mind, give it voice. I don’t bite. I promise.

Sebastian

Sara: Ivo killed Shado. He’s the one that pulled the trigger.
Oliver: Because I chose to save you. He needs to know the truth

Diggle: I've just never seen you spooked like this before.
Oliver: That should tell you something.

Not to tell you how to do your vigilante-ing but the grease paint thing is a poor identity concealer.

Barry

Sebastian Blood: You know who he is under that hood, don't you?
Slade: I know exactly who he is. He's my friend.

I will arrange for you receive another sample of my blood, and then you can begin to mass produce the serum again.When I ask you not to confront the vigilante, you will listen. Remember, your mask can be worn by another.

Slade

I know I called you a murderer, but you are not. You are a hero. You beat the island. You beat my father. So fight, Oliver. Get up and fight back.

Tommy

The island didn't make you strong, kid. It revealed you to be weak.

Slade

Oliver: You're dead.
Slade: You're not a hero. Or a friend. Or a brother. You're nothing.

Oliver Queen. He is a billionare by day and saves the city by night.

Barry

Arrow Quotes

Sara: That's not true. I wanted to kill Roy because that's what I do. That's who I am. I spent six years in the darkness and I looked into the eyes of the devil and I gave him my soul.
Oliver: I can help you get it back.
Sara: No. You deserve someone better. You can harness that light that's still inside of you, but I'm not that person and I never will be.

There is a prophecy. The man who doesn't perish at the blade of Ra'a al Ghul will become Ra's al Ghul. Ra's al Ghul doesn't offer, he orders. Oliver! Don't delude yourself into thinking you have a choice.

Malcolm
