Oliver and Dinah in “Unfinished Business”

Oliver

I wore that mask for a reason. Now that I've taken it off, maybe the consequences are finally catching up with me.

Dinah

Well, you can't take responsibility for every choice some lunatic makes, you know?

Oliver

No. I have to take responsibility for this. Me being on the force puts your reputation at risk, and it's putting lives in danger.

Dinah

Cops face risks every day. That is the job. And you are not putting anyone's life in danger, not unless you stop fighting for them. You think you're gonna do one interview, and all of a sudden your problems go away overnight?

Oliver

I think I have been so obsessed with proving to people I'm not my father that I didn't stop and at look at all the ways that I am exactly like him. I should have come clean with Sam years ago.

Dinah

But you didn't, and you can't stop the past from haunting you. The only thing you have control over is what you do going forward.
