Slade and Oliver in “Unfinished Business”

Slade

Would you like to explain what's going on?

Oliver

Like to talk about you for a minute. You seem--

Slade

Like in possession of all my marbles? [Oliver nods] The mirakuru wore off a long time ago, kid. I mean, I remember everything that happened. I'm not trying to escape that. But it feels like some bad dream. Regardless of my sanity, why do you want to help me? After everything I've done?

Oliver

There is a man here on the island named Adrian Chase. He's holding my friends, and my family, hostage. Including Thea. And my son.

Slade

[slightly amused] Since when do you have a son?

Oliver

Slade. Are you gonna help me or not?

Slade

I think I'm stating the obvious when I say, I killed your mother. For that alone, you should've killed me.

Oliver

Maybe what's happening now is the reason I didn't. [hands Slade a flash drive] This is all the intel that I've been able to gather on your son, Joe. Including his present whereabouts.

Slade

Are you offering to help me find my son--

Oliver

I want us to find both of our sons.

Slade

You and me, kid. Like old times.
