Bridget was a Galatean
Biography
During a war between the humans and the Galateans, Bridget went undercover as a nun on a human expedition to a space station where a first expedition of nuns had went missing. During the expedition she met The Doctor and Amy Pond who had been brought to the space station by the TARDIS. They discovered a primative time engine aboard the spaceship which was accelerating the flow of time. This caused the a creature to mutate from the TARDIS. It was mde up of several life forms absorbed by the TARDIS due to a mutation from the jungle on Planet Basingstoke, which also grew from the TARDIS. The Doctor managed to lure the creature into a teleport where he hoped to reconstitute it into its original parts. Bridgets cover was blown when the Doctor noted that she had not aged while everybody else had. She subsequently activated an army of Galatean plague robots to attack Ivana, the Doctor and Amy, the latter of whom had been aged by many decades. They killed Ivana, but before she died she activated some explosives near the time engine, causing the flow of time to increase at a dangerous rate, ageing the jungle to death and scrampling the circuits of all the Galatean robots on the space station. The Doctor and Amy survived at the heart of the time storm and were taken by the plague robots to Bridget and the teleport where the creature inside it had evolved into Chiyoko. Bridget and the plague robots worshipped her as a combination of flesh and machine; the ultimate expression of existence. Chiyoko simply said "Oh my little tin people, you are so funny!" Before destroying Bridget along with the rest of the plague robots. (DWM: Apotheosis)
