Diggle: There's only one thing left of him now.
Laurel: And what's that?

Felicity

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.

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.

Felicity: If you're going to keep going out into the field, we should really design you some sort of...

Nyssa: Like what?
Laurel: Like a normal person.
Nyssa: I am a normal person.

Nyssa: I never understood your country's need to fry everything.
Laurel: That's because everything tastes better that way.
Nyssa: This is more oil than potato.
Laurel: Put it in your milkshake.
Nyssa: I sense you mocking me.
