Diggle: I’ll make you one more promise: there’ll be no more secrets between you and me.
Dinah No more secrets.

OK, you weren’t gone that long.

William

Slade: You should have gone home.
Oliver: I don’t abandon people… even when they leave me drugged.

Slade: I will join the Jackals as long as you let my boy go.
Nylander: It's like I said, it's not so simple. We need your son. After all...he is our boss!
Joe: Hello, father. It's been a long time.

William: Were you able to help your friend?
Oliver: No I wasn't.
William: I really hope he finds his son.
Oliver: Yeah, I do too.
William: Is there anything else you can do for him?

Nylander: He is not that bad! [laughs] Slade Wilson, the terminator!
Slade: I haven't heard that name in a while.

Oliver: I have an old friend in town that needs my help and I might not be back at the office for a few hours. Do we have any idea who the shooter was targeting?
Rene: We're working on it.
Oliver: Good. Be the mayor until I get back.
Rene: For real?
Oliver: No...it's a figurative speech. Just don't make any laws while I'm out of the office, OK?

Oliver: Hello? Hi...OK. I will be there. Mhm, alright.
Felicity: It didn't sound like John or the team.
Oliver: It wasn't.
Felicity: What's going on?
Oliver: That was Slade Wilson, he needs my help.

Black Siren: Excuse me?
Jenny: [breaths out]
Black Siren: Here you go.
Jenny: Thanks, I'm such a clutz!
Black Siren: Don't worry, me too. I love your shoes, they're so cute.
Jenny: Custom designed! Girls can rock limited-editions kicks too, right?
Black Siren: Absolutely. I'm Dinah by the way.

Felicity: I was just telling Oliver how I'm being stretched too thin.
Curtis: Wait, what do you mean by "just"?
Felicity: We were at dinner when I got your text.
Curtis: Felicity!
Felicity: No, it's the job, it's OK!
Curtis: No, no this is all on me, I 911'd you over one damn dead body. Can you at least make it back to dessert?
Felicity: Well no, we have to find evil Laurel.
Curtis: No, no I'll find evil Laurel, you go out there and take your ass back to your man!
Felicity: Are you sure?
Curtis: Are you kidding me? I was like you guys' biggest shipper.

Diggle: I knew you would be around here somewhere.
Black Siren: Well I couldn't stay away from you. Except you have changed something about yourself. I just can't quite put my finger on it.
Diggle: Then let me help you with that!
Black Siren: So it's a crossbow? That's cute.

Oliver: I know when I took William in, we agreed that we'd keep our distance because he was going to have a lot to process.
Felicity: He still has a lot to process!
Oliver: He does and every day there's a new challenge.
Felicity: I sense a but coming, there's a but coming right?
Oliver: But then I saw you with him and I became 100% sure that, if you want, his life will better with you in it. Just like mine.
Felicity: Are you sure that's what you want?
Oliver: I'm sure.

Arrow Season 6 Quotes

Black Siren: God you're such a bitch!

Raisa [to Oliver]: You had trouble fitting in, in age.
Oliver [to Raisa]: What?! What are you talking about? I had Tommy.
Raisa [to Oliver]: I wouldn't call having a friend who helps you get in trouble, "fitting in".
Oliver [to Raisa]: That's a fair point.
