Peri is strapped down and gagged as the operation is prepared and Crozier gives the order for her head to be shaven. The Doctor attempts to return to save her but is suddenly drawn hypnotically into the TARDIS, which appears in the hallway; it is later revealed that he travelled directly to his trial from that point. Despite the Doctor claiming that the Time Lords' interference has put Peri's life in danger, the Valeyard rebuffs this, stating that the Doctor shouldn't have become involved in the first place, and Peri's life is the cost of his involvement. Events on Thoros Beta continue after the Doctor's removal, as it is shown that Ycranos was placed in a time bubble by the Time Lords to hold his arrival back at the lab until after Kiv's mind was successfully transplanted into Peri; when Yrcanos is freed of the bubble, he is distraught at the results of the operation, and fires wildly, killing Peri. The Valeyard insists that the interference of the Time Lords was to prevent a greater disaster befalling the universe due to the mistakes in the Doctor's actions. The Doctor insists that the present trial appears to be serving a greater cause, and resolves to determine what it is as the trial continues.
