I don't trust anyone's word, Mr. Diaz. I put my faith in data, information. Ones and zeros never lie. This is digital proof that one of you has betrayed me.

Cayden

I'm never going to let anything happen to you William, ever. And I'm promising you that I'll do everything that I can to make sure nothing happens to me.

Oliver

This city.. It's prime for a takeover.

Ricardo

William: There's a prep sheet for the trip, and I tried one of the extra credits. (pulls out the sheet from his backpack] Would you take a look at it?
Oliver: Yeah, of course.
William: I meant... Felicity.
Oliver: I'm sure you did, yep.
William: I'm sorry. It's a math problem from the hyperbolic geography in marine organisms, like coral.
Oliver: I do know what coral is, but that's okay.
Felicity: This is a high dimension math problem most people don't get until they're in... 12th grade AP. And it's perfect.

Rene: Hey, man, new Team Arrow's kickin' ass.
Curtis: You know what? I really have to say what we should change our name. Like, what do you guys think of "The Outsiders"?
Dinah: Ooo, ah, I think it was a really awesome book.

Thea: Cool, just like the old days.
Quentin: I'm not that old!

Curtis: 1-2-3, suit up.
Rene: Yeah, I don't think we should say "suit up" altogether.
Curtis: It'd be really cool if we did, though.
Rene: I don't think it would be really cool

I'm so sick of everyone not killing him when they get the chance!

Black Siren

Dinah: Yeah, but if Cayden had audio and video on all of us, especially Oliver, why would he just tee up Rene?
Rene: It figures he'd go after the most handsome and charming.

You ever consider a spotlight? Big light in the sky in the shape of an arrow?

Jerry

Curtis: I brought crogurts.
Rene: Crogurts?
Curtis: I didn't name them. I just eat them.

I’m not saying it is me, but it could literally be any of us.

Curtis

Arrow Season 6 Quotes

Black Siren: God you're such a bitch!
Black Canary: Yeah it takes one to know one, sweetheart!

Raisa [to Oliver]: You had trouble fitting in, in age.
Oliver [to Raisa]: What?! What are you talking about? I had Tommy.
