Crozier interrupts the interrogation, believing he can extract more information from Peri, but then Yrcanos arrives, ready to kill the Doctor. Peri stops Yrcanos, and together they escape, regrouping with Yrcanos' men. As Kiv's body is dying, Crozier is forced to transplant his brain with the Doctor's help into the body of one of the Mentors' servants, keeping the mind alive but affected by the simple thoughts of the former consciousness. Yrcanos, Peri, and his men launch another attack, this time on a weapons stash, but are stunned and captured. Sil and Crozier decide to use Peri as a more suitable body for Kiv's brain, despite the Doctor's objections. As the operation is being prepared, the Doctor sneaks away and frees Yrcanos, urging him on for Peri's safety.
