Felicity: This isn't about them being together. This is about me, K? Sara can analyze blood, she can kick ass, she can do anything. And the one I'm supposed to be good at I'm failing at miserably. Why do you even need me now that you have her?
Diggle: Because you're irreplaceable Felicity.

Roy: Do you two know each other?
Sara: No, we don't.
Sin: Right, we don't. I just love when people come back from the dead. It juices my zombie fetish.

Sara, when you come back from the dead you get a party. It's a Queen family tradition.

Oliver

Sara: I wasn't trying to be a bitch.
Laurel: The title of your autobiography.

Because if half of the stories I've heard about Ra's al Ghul are true and Sara kills his daughter, we all will pay.

Oliver

Oliver: What part of this is bothering you. It is about your family?
Felicity: No. It's about yours.

What's the matter? They didn't teach you about right crosses in assassin school?

Lance

Lance: You know you never did tell me how you joined up with The Arrow in the first place. How did you two meet?
Sara: Vigilante club.

I was with you because I loved you.

Sara

You had an affair with Malcolm Merlyn about one year before Thea was born. Merlyn is Thea's father.

Felicity

Roy: Does this group have a name, like "Team Arrow" or something?
Oliver: We don't call ourselves that.
Felicity: I do. Occasionally.
Oliver: Stop.
Diggle: Welcome aboard.

So, the secret society gets a new member.

Diggle
