Felicity: I don't doubt that. I don't doubt that you can beat him, but I'm terrified that you won't kill him because that's not who you are anymore and I am so afraid that Ra's al Ghul is going to use your humanity against you.
Oliver: Felicity, I honestly don't know if I'm a killer anymore, but I do know two things. The first is that whoever I am, I'm someone who will do whatever, whatever it takes to save my sister.
Felicity: And the second thing?
Oliver: I love you.
Ray: Advanced Technology Operating Mechanism. ATOM.
Felicity: What are you going to use it for?
Ray: To protect the people of this city. And I want you to help.
Felicity: Why does this keep happening to me?
Oliver: You think you know who Malcolm Merlyn is, but there are things I discovered years ago, recently that... he doesn't love you, Thea, because he's not capable of it.
Thea: Ollie, please. Don't. Don't make me choose between my father and my brother.
Oliver: I won't make you choose. You're my family and there's nothing I won't do to protect you.
Thea: What does that mean?
Oliver: It means I love you, no matter what.
Laurel: Mom, can I tell you something? Whoever killed Sara, I'm going to find them no matter what it takes and I am going to make them pay.
Dinah: Then you make them pay. And you make them suffer.
You're just a boy.Ra's al Ghul
My sister wasn't born a killer. Malcolm Merlyn made her one and I let it happen.Oliver
Felicity: Stop! Oliver. I can't imagine how difficult this must be for you, but John is right. Thea lied.
Oliver: She lied about Merlyn, but Sara... I don't want to believe she could so something like this.
Felicity: Which is why you shouldn't be the one asking the questions.
Felicity: I think I made it pretty clear when I said I didn't want to talk about this.
Ray: You were, but you were also pretty wrong when you said I regretted kissing you. I can't imagine there's a man on the planet who would ever regret kissing you.
Oliver: Felicity! Who killed Sara?
Felicity: You did.
Barry: Hey, by the way.
Barry: You were wrong. When you told me I could inspire people you said you couldn't. But you were wrong. You can inspire. Not as The Arrow. That guy's a douche. But as Oliver Queen.
Oliver: Thank you. By the way, you were wrong, too.
Oliver: Right now. Because you think you can kick my ass. I can tell.
Barry: Well if you think you can kick mine, you better do it fast.
Oliver: I get it Barry, you're fast. Ready!
Oliver: You can't expect me to believe that you don't want to know once and for all who would win -- me or you.
Barry: You mean if you don't shoot me in the back?
Oliver: You gotta get over that, Barry.
Barry: OK. I have super powers. You have arrows. That run out.
Oliver: I have strategy and tactical awareness.
Barry: When I'm fighting you, it's literally like you're standing still.
Oliver: It's tough talk, you ready to back it up?
Barry: Oh yeah.
Roy: It's cool. You guys are fun.
Cisco: So are you guys. Well, you could be if you realized you're working under a night club.
