Diggle and Oliver in “Unfinished Business”

Diggle

I don't know how you did it. You never hesitate to make the call. You were always sure. I'm not.

Oliver

I was never sure. Not one time. I'm very flattered that it looked that way on the outside, but on the inside, it was... it was instinct. It was instinct and it was fear.

Diggle

Yeah, but you worked past it.

Oliver

Well, you'll work past it, too. Now I'm not gonna sit here and say that you won't... make mistakes. That you won't... lose people along the way. You know, most... most will be strangers, but some... well, some won't be. Because, John, you're one of the main reasons that the Green Arrow even exists.

Diggle

What're you talking about?

Oliver

The Restons.

Diggle

The bank robbers.

Oliver

The bank robbers, yeah. You were the first person to convince me to look past just the names on my father's list. You helped me discover that the Hood, that persona, he wasn't a hero. You helped me find what all of this, the Green Arrow, the idea of it, it exists because you had faith in me. Now you gotta have the same kind of faith in yourself. Because if you do, you can be a better leader. You can be a better hero than I ever was.
