Oliver and Thea in “Unfinished Business”

Oliver

Please tell me you didn't send it. This thing with Collins' wife, he doesn't deserve that.

Thea

Felicity told you, didn't she?

Oliver

Yeah.

Thea

I haven't sent the e-mail, okay? Ollie, don't look at me like that. It's politics. There's about to be a vote, so it's time to play hardball.

Oliver

This isn't hardball. This is cruel.

Thea

What would be cruel is the people of this city not having you as the Mayor. The Anti-Crime Unit. Low-income housing. Common-sense gun legislation. Ollie, in the short amount of time you've been doing this, you've done a remarkable job. Please just let me do what I have to do to help you keep doing that.

Oliver

Felicity told me about this Collins thing because of something that John said to her. Thea, when you fight fire with fire, you are probably gonna get burned.

Thea

I won't. It'll be fine.

Oliver

Like it was with Susan? You destroyed her career, now you've graduated to blackmail. Where's it stop?
