Felicity, Diggle and others in “Unfinished Business”

Felicity

I'm running a surveillance on Curtis, Dinah and Rene, and I have worms crawling through their texts and emails.

Diggle

You're spying on them?

Felicity

I'm not spying on them! Like... keeping tabs.

Diggle

Oliver, why not just confront whoever this is and give them the chance to come clean?

Oliver

What makes you think they're gonna be forthcoming? How do we know that this isn't just the surface of this betrayal? I mean... look, John, I don't want to spy on them, but if you have a better idea... I'm all for it.

Felicity

Someone goes somewhere suspicious, we'll know.

Diggle

Felicity, we were all just at the wedding. The most suspicious place they can go is out for late-night pizza.

Oliver

John, either Curtis, Dinah or Rene gave me up. We need to know why, we need to know who. Otherwise, when you put the hood back on, you could be next.
