Granby

Granby was a young soldier, formerly serving in the Royal Navy before being assigned to the British Imperial Spacefleet, who was killed while scouting the Moon's surface. He had been killed maliciously by the Vrall, who took his brain tissue and used it to give themselves knowledge of Earth, absorbing the electric enzymes and thus his knowledge, allowing them to speak English and create a story that would appeal to the expedition. However, this helped the Doctor deduce the true nature of the Vrall; they claimed to gain knowledge of English via a telepathic 'download' from Turlough, but among other minor linguistic anomalies, they referred to robots as 'mechanical servants', which was a term that Granby would have used rather than Turlough.
