Doctor and Nyssa map the enemy’s weakness

The Doctor rushes to counter Tegan’s deepening connection to the Mara before full possession occurs. He calibrates a hypnosis device linked to an earpiece that suppresses dream-state brainwaves, the very frequencies the Mara depends on. Nyssa probes him for details, and he reveals their target: a tangible cave on Manussa linked to a symbolic ‘snake mouth’ in the dream realm. Trusting the clue lies near the estate, he prepares to abandon safer medical approaches for a high-risk gambit that could sever the Mara’s hold permanently. key_dialogue: [ DOCTOR: The Mara, speaking through Tegan's mouth. NYSSA: On Deva Loka you said a physical change took place when possessed by a Mara. DOCTOR: It does, as mental resistance weakens. But this time I can prevent it. ]
