Oliver Queen: I don't have time for a lecture, John.
John Diggle: There's no lecture here, Oliver, but you should know that Andy gave me a lead on Darhk and I've been working on it.
Oliver Queen: Good. What have you found?
John Diggle: Unfortunately, it was a dead end, but you should know...
John Diggle: But nothing. But nothing.
John Diggle: Oliver, I know you're hurting, man, but you should know that whatever your play is... I got you back.
Oliver Queen: But?
John Diggle: But you've come so far, Oliver. You've recovered a humanity that you lost when I first met you. I know you want payback for what Darhk did to Felicity, and you should. But don't lose what made her fall in love with you in the first place.
Laurel Lance: She was my sister. I couldn't be angry because she was dead. I couldn't grieve because I was angry. That's what happens when your sister dies while screwing your boyfriend. We buried an empty coffin. because her body was at the bottom of the ocean where you left her. it should have been you.
Oliver Queen: I know it is too late to say this but I am sorry.
Laurel Lance: Yeah, I am sorry, too. I had hoped you would rot in hell a lot longer than five years.
Oliver Queen: Well, Felicity's really going to enjoy hacking the NSA.
John Diggle: You mean after she's brought you a hundred Black Canary candidates for you to say no to? You're not the only one who visits, Oliver.
Oliver Queen: John, I understand what I promised Laurel. Now that were actively doing it, trying to replace her, it just... it feels wrong.
John Diggle: You don't want to find someone to replace her. Just someone to take on the mantle. And from where I'm sitting, those are two very different things.
