Oliver and Dinah in “Unfinished Business”

Oliver

I'm not here to apologize.

Dinah

Of course you're not.

Oliver

I'm here to explain that... this wasn't all for nothing. Felicity's been going through the data that Vince pulled out, and for the first time, Dinah, for the first time... we have some viable options.

Dinah

"Viable options"? You know, I used to tell Vince his way of seeking justice wasn't 'viable'. I convinced him to change. Just how you convinced me. But you know what, Oliver? Vince was right. The only way to bring justice to this city is with a bullet.

Oliver

No, Dinah, I need you to listen to me --

Dinah

I'm going to make sure Vince didn't die for nothing. I'm going to kill every last one of them. Starting with Laurel.
