Diggle: He's not coming back, Oliver. I know you don't want to believe it, Laurel, God knows I don't but, he's not coming back.
Laurel: Are you? Are you coming back?
Diggle: I don't know. For the first time since I met Oliver Queen I don't know what happens next. I know it's silly, but I still like to think of myself as Oliver's bodyguard. I just couldn't protect him. It's funny. He was worried something would happen to me.

Diggle: That's just the thing. Once we let the ends justify the means, that's just the first step.
Malcolm: Towards what?
Diggle: Becoming you.

Roy: You think you're the only person who can stand up for Thea?
Oliver: I'm trying to figure out why you're standing up to me!
Diggle: Alright. Maybe we just need to throttle back.
Felicity: No! We need this. Oliver, you were gone, dead, at least we thought you were, and we had to go on with our lives and doing that meant not doing things your way.
Oliver: Fine. I'm back now!
Felicity: That doesn't mean we can go back! And you do not have the right to come back here and question everyone's choices.

Listen, I know what you're doin' and I know why you're doin' it, but you can't save Thea's soul at the thought of your own.

Diggle: So, pretending for a moment that we aren't two dead men chained to the floor, how do you feel about being my best man?
Oliver: I feel pretty good about it.

Oliver: He said I can do more as the new Ra's than I could ever do as Oliver Queen or the Arrow. That I would have unlimited resources. That I could make a difference, not just a dent.
Diggle: You aren't really considering this, just because Capt. Lance is angry and Felicity is momentarily unavailable?

League of Assassins. Huh. You're feared for your bravery and power, but all I see is a bunch of weak men running from their lives, trying to escape. That's not power, Maseo, or brave. That's cowardly.

Felicity: If you're going to keep going out into the field, we should really design you some sort of...
Diggle: Do not say costume.
Felicity: OK...identity concealment.

Diggle: And since when is Ra's' daughter someone we stick our necks out for, Laurel?
Laurel: I know you're furious with Ra's for what he's done with Oliver. We all are. But Nyssa. She saved my sister's life. She gave her a home. She's a good person in spite of everything that she grew up with. And the last time that I checked, protecting good people? That's what we do.

Laurel: If anything happens with Nyssa, let me handle it on my own.
Diggle: Laurel, we're talking about the League of Assassins.
Laurel: I know that. I just...Oliver. You were closer to him than any two people I have ever known. You shouldn't have to...
Diggle: Fight him? Kill him? It's not going to come to that. Look, I'm with Felicity. There is nothing that Ra's al Ghul can do that can turn Oliver against the people he loves.

Diggle: There's only one thing left of him now.
Laurel: And what's that?
Diggle: Us.
Thea: Gone but not forgotten.

Felicity: I can't believe he's gonna marry her.
Malcolm: You should worry more about getting out of here alive.
Ray: Is that even a remote possibility?
Laurel: Oliver would never let that happen.
Diggle: He let this happen.

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
