Poggit
Mrs Poggit was an elderly Human living in Upper Leadworth. She lived in the old people's home along with the rest of the pensioners of the town. In the fake world created by the Dream Lord, her body was taken over by an Ecnodeen, a member of an alien race that fled their world and lived in the bodies of old people, keeping them alive for many years. When the Doctor, Amy Pond and Rory Williams woke up in the dream world, she asked the Doctor if he could try on her jumper for her nephew, but when he tried it on, he examined her stating that she was really old, older than any normal human, then he fell asleep again. Soon, they noticed Mrs Poggit walking to the children's trip, wondering what 'she wants'. When the woke up again, they found out that all the children were 'dead', and that they were killed by 'Mrs Poggit', because the aliens (who took over the pensioners) had an "eye" in their mouths, which could release a gas which disintegrated their enemies. They did this to people because they wanted revenge for what happened to them. When the Doctor confronted them, the postman arrived but Mrs Poggit 'killed' him. They escaped, but Rory and pregnant Amy were trapped in the baby's future room in their house. When the Doctor climbed through the window, so did Mrs Poggit and she "killed" Rory, but the Doctor whacked her with a lamp and she supposedly fell to her death.
This reality, however, was not real, meaning Mrs Poggit is still alive and well in the real 21st century Leadworth. (DW: Amy's Choice)
