I don't know nothing about no diamond. The inflection in your voice, the way you can't...

Cassandra Cain: Cassandra Cain: I don't know nothing about no diamond. Harley Quinn: The inflection in your voice, the way you can't hold eye contact, and the fact that you're a filthy little thief, all suggest that you do. Now, you can give it to me, or I can give you to the man that diamond belongs to. But trust me when I say, you're not going to like what he's going to do to you. Now, hand it over. Cassandra Cain: Yeah, not going to happen.

You wanna go there? Come on. Empty your pockets. All of it. Cassandra Cain, back already? Thought by now you'd figure out how not to get caught. What? No comeback? You all right? You smell like shit. Simpson. Any clean clothes in lost and found? These are serious accusations, Miss Montoya. The Sionis family name is on half the museums and schools in Gotham. And that makes him immune to the law, Captain? Montoya's day is going almost as badly as mine. Remember the guy who stole her promotion? That's him. He had four people killed alone last night. If Roman Sionis is such a mastermind, how'd he get fired from his own fucking company? The Janus Corporation is his father's company, thank you. And by the way, they cut him off. Where does the DA's office stand on all this? To make matters worse, the assistant DA? That's her ex. The evidence that Sionis is linked to these murders... There's a shipment coming in. Drugs? - A diamond. - A diamond. Montoya. Should we call the Feds for backup? Listen, I had a source at the club. His driver. He said that Roman couldn't stop talking about this thing. And he said that he overheard something about laser-encoding. Now, I did some research. I think it's the Bertinelli diamond.
