Diggle and Oliver in “Unfinished Business”

Diggle

If we do this, Cayden James will bring his whole group here.

Oliver

Yeah.

Diggle

And Cayden will bring everyone, Oliver. I'm no place close to a hundred percent. But look... the rest of the team --

Oliver

There is no "rest of the team".

Diggle

Oliver, we could use their help. All you have to do is ask.

Oliver

We would have to trust them, and we can't. We can't. John, we've been over this.

Diggle

I know. But we've also been over other things. Like you and the League of Assassins, me with my secret. Oliver, the best partnerships are built on forgiveness, man. No one knows that more than you and me.

Oliver

I got arrested in front of my son. Dragged away in handcuffs because of something that Rene did. I don't know how to forgive him. I tried. John, more important,... what's Cayden James up to? We don't know. He has known our identities for months. He hasn't outted us. Why? This started with you, with me, and with Felicity. Whatever comes our way, we can handle it. I believe that.
