Kamelion exposes the Masters influence

Peri has cornered Kamelion in the TARDIS console room to force answers about the robots unnatural behavior. Kamelion removes a partially burned circuit board from the console, revealing it carries the Masters taint. The act of extraction mirrors his own struggle to purge himself of the Masters control. Peri seizes on the mention of the Master as a way to understand why the ship has been behaving erratically and endangering all of them. Kamelion speaks only in fractured bursts, betraying both his own panic and the lingering Master’s grip, while Peri presses for clarity amid the rising danger on Sarn. The moment forces Peri to confront the depth of the Masters reach and the fragility of their situation as the planet looms toward destruction.
