Locked up in C982's hold, the Doctor deduces that the strange sound was some kind of sonic hypnosis device that caused Hardy to hallucinate and see what he most feared. As the enemy boarding party burns its way through the airlocks, Hardy gets the Doctor and Jo to use as hostages, but when the airlock door bursts open, the boarders are not Draconians, but Ogrons. The Ogrons' energy weapons stun the two pilots and the Doctor. They then tie Jo up, taking the ship's cargo and the TARDIS as they leave. When the Doctor revives and releases Jo, she tells him what the Ogrons did, and wonders if they are working for the Daleks, as they were when she first met them. The Doctor points out, however, that the Ogrons are mercenaries.
