“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”

“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?”

“Brilliant, Piter! I'm glad I didn't execute you all those times when you were so annoying.''So am I,' de Vries said.”

“...the beautiful thing--perhaps the thing I love most about the gospel-- is that everything we learn we can use and take with us and use it again. No bit of knowledge goes wasted. Everything you are learning now is preparing you for something else. Did you know that? What a concept!”

“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”

“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.”
