Felicity Smoak: Oliver? Oh my God!
John Diggle: Oliver?
Oliver Queen: Chase had me... and he let me go.
John Diggle: Go slow, man.
Oliver Queen: It's over.
John Diggle: Oliver, we're gonna get this son of a bitch for whatever he did to you.
Oliver Queen: John, it's... It's over for me. I don't wanna do this anymore. I'm shutting everything down.
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.
Oliver Queen : I'd say thanks, but I really don't think that would cover it.
John Diggle : Well, like I told your cop friend, I was just doing my job. Besides, I think I'm the one who should be thanking you.
Oliver Queen : For what?
John Diggle : The knife.
Oliver Queen : The knife. I got lucky.
John Diggle : That was a kitchen knife. It wasn't even weighted properly, yet you threw it for accuracy across a ten-foot room.
Oliver Queen : Exactly. I got lucky.
