Doctor explains Draconian perception filter to Jo

Trapped in a cramped metal room aboard the cargo ship C982, the Doctor and Jo attempt to make sense of their captors' behavior. The Doctor deduces that the Draconians are using ultrasonic technology to distort sensory perception, making them appear as monstrous Dragons to the crew. He reveals the nature of the false visions Jo experienced, including the Drashig and the gunman she saw, while connecting this encounter to the escalating tensions between Earth and the Draconian Empire. The revelation sharpens the immediate danger, forcing Jo to confront both the enemies outside the room and the distortions within their own perception, which heightens the urgency of their escape.
