Yep. He'll talk to you just to pointlessly insult you with no real rhyme or reason. He thinks he's a real slickshit killer 'cuz he's been doin' it so long, but it just makes him arrogant and stupid.

He's probably only interested in you to worm you for information about Zexion. I'd just give it to him, if I were you. The more people play hard to get with it, the more interested he's gonna get, I'd say.
