Diggle: I didn’t want you to worry, Oliver, which is why I didn’t tell you.
Oliver: No, John, you didn’t tell me because you knew I’d never let you go out there compromised and that I’d certainly never let you compromise the team. I have been mad at you before, John, this...is the first time I have ever been disappointed.

If I was dating the Green Arrow I think I'd know. Besides The Flash is much more my type.

Felicity

Cayden: You do see how that could have gone wrong, yes?
Black Siren: Yes, but it didn't!

Diggle: I never should have said I was doing it for you. Remember last year, when the Dominators put us into this alternate Star City?
Oliver: Yeah, kind of difficult to forget.
Diggle: We got to see what our perfect life would be. Mine was being the Green Arrow.

He has a son? I’ll make sure he suffers, too.

Joe

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?

Arrow Quotes

You know Oliver, somebody once told me that secrets have weight. The more you keep, the harder it is to keep moving.
