Diggle and Stewart in “Unfinished Business”

Diggle

Hey, I, um... wanted to say thank you. I know, this... I know I haven't made it easy for you.

This is the most time we've spent together since you turned 18. As hard as it may be to believe, I'm grateful for it. Yeah, I'd prefer a round of golf to kidnapping and... and torture. I know you might not feel the same way, but you will always be a son to me.

Diggle

Oliver told me the truth about Vlatava, about my father. Why did you let me believe a lie? You let me hate you.

Every child deserves to believe that his father is a hero. And believing it, you became one. If he could see you today, I know he would be so proud of you.

Diggle

If I'm a hero... it was all because of you... sir.

[getting on the elevator] John?

Diggle

Yes, sir.

Call your mother.
