John Diggle: Sometimes, me and Oliver come down here after, you know, tough nights. He would pour this, look up and say "Prochnost."Roy Harper: What does that mean?John Diggle: I have no earthly idea. To Oliver.Roy Harper: To Oliver.
Oliver Queen: I didn't know, Felicity. Five years ago, I was a completely different person. And I had... no idea that something like this was even... possible. I couldn't have imagined. When you and Diggle brought me back to Starling City, I made a vow to myself that I would never let anything like the undertaking happen again.Felicity Smoak: What's happening now is not your fault.Oliver Queen: Yes, it is. I have failed this city. Yao Fei. Shado. Tommy. My father, my mother. All that I ever wanted to do is honor those people.Felicity Smoak: You honor the dead by fighting. And you're not done fighting! Malcolm Merlyn, The Count, The Clock King, the Triad - everyone who is trying to hurt this city, you stopped them. And you will stop Slade.Oliver Queen: I don't know how.Felicity Smoak: Neither do I. But I do know two things: You are not alone. And I believe in you.
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.
You know,dig, When I confront somebody on the list, I tell them that They failed this city. But tonight, It was me who failed.
