“Are you already training my replacement? Piter demanded. "Replace you? Why, Piter, where could I find another Mentat with your cunning and venom?""The same place you found me, Baron.""Perhaps I should at that," the Baron mused. "You do seem a bit unstable lately. And the spice you eat!""Are my pleasures too expensive, Baron? Do you object to them?""My dear Piter, your pleasures are what tie you to me. How could I object to that?”

“Come, come," the Baron said. "We don't have much time and pain is quick. Please don't bring it to this, my dear Duke." The Baron looked up at Piter who stood at Leto's shoulder. "Piter doesn't have all his tools here, but I'm sure he could improvise.""Improvisation is sometimes the best, Baron.”

“Ah, Hah! But you see, Baron, I know as a Mentat when you will send the executioner. You will hold back just so long as I am useful. To move sooner would be wasteful and I'm yet of much use. I know what it is you learned from that lovely Dune planet - waste not? True, Baron?-Piter De Vries”

“Sometimes I wonder about Piter," the Baron said. "I cause pain out of necessity, but he...I swear he takes a positive delight in it."-Baron Vladimir”

“Ah! Indeed but! But he consumes too much spice, eats it like candy. Look at his eyes! He might have come directly from the Arrakeen labor pool. Efficient, Piter, but he's still emotional and prone to passionate outbursts. Efficient, Piter, but he still can err. -Baron Vladimir”

“Isn’t there one thing I can ask of you that you won’t disregard?. . . . You could just reply, "Yes, Baron," and be done with it.' Yes, Baron.”
