Ra's al Ghul: You tasted death, and you wanted more, but the truth is everyone, and everything must come to an end. Even for one such as me.
Oliver Queen: Kill me, but spare John Diggle's life. Let him go. I will beg for it.
Ra's al Ghul: You have shown tremendous strength, fortitude, power. No, Mr. Queen, I do not want to kill you. I want you take my place. I want you to become the next Ra's al Ghul.
John Diggle: What is it, Oliver?
Oliver Queen: I'd like you to do something for me.
John Diggle: If it's suit up as Green Arrow, Felicity and I already talked about it, and we don't think it's enough to take the heat off of you.
Oliver Queen: That's not why I'm asking.
John Diggle: You're serious.
Oliver Queen: Every time that I'm out there as the Green Arrow, I'm a target of the FBI, of the Bratva, of the threats that are out there, and the threats that are undoubtedly coming. And on my own, I can take it. I'm not on my own anymore. I cannot be responsible for my son losing the only parent that he has left.
John Diggle: Oliver...
Oliver Queen: Star City needs the Green Arrow. It just can't be me anymore, so I'd like it to be you.
