Edie was a woman who lived in the Edifice.
At this point, the viral advertisement for the Edifice contacted her. As she was looking for a retirement home, she planned to agree but was kidnapped anyway. She had no problem with this and made no attempt to escape. When the Tenth Doctor and Donna Noble were also kidnapped, she introduced herself and brought them a fruitcake. When the other inhabitants of the Edifice were returned, she stayed behind as she did want to live there. (AUDIO: The Forever Trap)
