Slade: Don't worry. I am not here to harm you.
Laurel: Go to hell.
Slade: All in good time, I'm sure. But before then, I've come to Starling City to see Oliver Queen suffer.
Laurel: Oliver? What?Why?
Slade: Because he's not the man you think he is.
Laurel: How would you know that?
Slade: Because I know Oliver Queen is The Arrow.

Queen Consolidated's Applied Sciences Division is now fully dedicated to replicating a serum based on your blood sample.

Sara: And I think you're just blaming Oliver because you lost Slade.
Roy: Of course you're on his side. You're screwing him.

You're special forces, she's an international assassin. You'd think that between the three of us we could have gotten answers out of Slade ourselves instead of turning him into the police. Here's what's really sick, is we didn't even question him because he said it was the right thing to do. Just like he said I had to break up with Thea one week after telling me to leave her alone!

Roy

We can't do anything without King Queen's permission.

Roy

Your brother has a secret, Thea. Would you like to know what it is?

Slade

Oliver: How'd you get off the island?
Slade: That is your first question/
Oliver: Well, you've made it pretty clear that you're not going to tell me where my sister is so, yeah, that is my first question.

Oliver: They're calling you Deathstroke.
Slade: That's a bit flamboyant. I like it.

Well, I told a guy the truth and he got struck by lightening. To be fair, it probably won't happen again. Statistically.
