The Doctor uses the telepathic machines (which operate at the same frequency as the TARDIS's) to take control. He investigates the memory of the other victims and, through the vision of the small boy - who has appeared at intervals throughout the story - discovers that Bronwyn also witnessed the crash, and contains some of Balor's soul. 'Hitching a ride' on the telepathic waves, the Doctor contacts Rose, instructing her how to alter the machinery to affect adults rather than children.
