Turlough sabotages TARDIS distress signal

Turlough deliberately disables the TARDIS distress signal by ripping wires from the console panel, interrupting a Trion ship's transmission and halting Kamelion's erratic spasming. The Doctor arrives mid-act and soon realizes the coordinates have been altered, suspecting Kamelion’s involvement. Turlough deflects blame, insisting the interference was for Kamelion’s sake and implying the robot may have automated signal changes. His deception plants the first seeds of distrust, revealing a hidden allegiance that will unravel the crew’s fragile trust just as Sarn’s volcanic crisis looms. key_dialogue: [ TURLOUGH: How's Kamelion?
