Hayt enters the guarded chamber where Bijaz is being held and identifies himself, but Bijaz immediately rejects the name Hayt and calls him Duncan Idaho. Bijaz says he witnessed Duncan Idaho’s dead flesh enter and leave the Tleilaxu tanks, forcing Hayt to confront the possibility that his ghola identity conceals a deeper past.

Hayt questions Bijaz about the Tleilaxu plan and first assumes Bijaz is a weapon aimed at Paul or Alia. Bijaz answers indirectly, mocking Hayt as both man and mask, describing Paul and Alia as a dangerous double-being, and suggesting that the Atreides twins’ own mother will not live near them.

Hayt realizes that Bijaz’s real target is Hayt himself. Bijaz begins a repetitive hum that causes pain, disorientation, and loss of control in Hayt. Bijaz says Hayt is the instrument he was trained to play, names additional traitors among the Naibs and officials, and explains that the Tleilaxu produce tools and services rather than mere artifacts.

Bijaz addresses Hayt as Duncan Idaho and uses command words to freeze him, proving that the ghola can still be manipulated. Bijaz reveals the implanted trigger: when Paul comes to Hayt and says that Chani is gone, Hayt will speak with Bijaz’s message. The message will offer Paul a Tleilaxu-made ghola of Chani, preserved from her flesh, able to bear his children and even be altered or improved.

Bijaz explains the price of the offer: Paul must renounce his godhead, discredit the Qizarate, discredit himself and Alia, and relinquish his CHOAM holdings. While Paul is emotionally vulnerable, Hayt is to move close and kill him. Bijaz then commands Hayt to forget until the trigger comes; after Bijaz claps, Hayt loses the thread of what happened and returns to accusing Bijaz of trying to manipulate him.
