Doctor removes Sarah's torture device

Sarah suffers escalating hallucinations from the Sontaran brainwashing device, believing rocks fall on her and that mud climbs her legs. The Doctor urgently breaks the forcefield holding the device before Sarah is psychologically destroyed. He removes it and she collapses from the sudden relief. Styre mocks the Doctor's futile compassion before taunting that he will now subject the Doctor to the same mental assault. Their tense standoff reveals Styre's ruthless prioritization of conquest over individual suffering. key_dialogue: [ DOCTOR: Sarah! Listen to me, Sarah! It's not real. Do you understand? Nothing is happening to you. It's only in your mind. DOCTOR: Fight it, Sarah. Fight it. STYRE: Very touching. DOCTOR: You unspeakable abomination! STYRE: Words, Earthling, will never prevail against Sontaran might. DOCTOR: Why did you do it to her? STYRE: I did nothing. I merely resurrected those things which lay buried in the depths of her pathetic little mind. She was a victim of her own fear. And now, your turn. ]
