Roy: I'm going to miss this. I feel like I was just starting to get good at it.
Oliver: You are getting good at it.
Roy: That guy? He said I was just another weapon in your arsenal.
Oliver: Well maybe that's what we should call you, then. Arsenal.

Oliver: When I said I wouldn't train you, I was trying to protect you. But a homicidal former vigilante apprentice was not what I had in mind.
Laurel: I know you're trying to protect me, Ollie, but I'm not helpless.
Oliver: I've never seen you that way. But. Laurel, I'm always gonna watch out for you. And it's not because I think you're helpless, it's because I care about you.

Ted, your mistake wasn't cutting him loose. It was losing faith in him.

The Arrow

Roy: Don't abandon me.
Oliver: Never.

Don't you get it? He's using you. You're not a human being, man. You were just another weapon in his arsenal. And the second you do something wrong, he'll turn his back on you. He will abandon you!

Stanzler

If Roy killed Sara, then we'll deal with it.

Oliver

Oliver: You're playing a very dangerous game, Laurel.
Laurel: I can handle it.
Oliver: No you can't, because you haven't realized that it's not actually a game.

The Arrow: You cannot be serious.
Laurel: I am not on your team. I don't work for you.
The Arrow: Exactly. You're untrained.
Laurel: Oh. And whose fault is that?

The Arrow: We need another minute.
Ted: How do you two know each other?
Laurel: We used to date.

The Arrow: Who else knows about the locker?
Ted: No one. This is where I kept my supplies, a safe place separate from my day job. As I'm sure you got one just like it.
The Arrow: Mine's bigger.

The Arrow: I've never heard of another vigilante in Starling.
Ted: It was six years ago. I wasn't news; I stuck to the Glades.
The Arrow: And these are supposed to convince me? Masks are also useful for serial killers.
Ted: Says the guy currently wearing one.

The Arrow: That's the second time I've found you with a body.
Ted: I've never killed anybody. I'm being set up.
The Arrow: And why should I believe you?
Ted: Because I used to be a vigilante. I used to be you.

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.
