When the Avatar tried to talk with her, it became clear that she was suffering heavy dementia, as she couldn't remember the most mundane things and actually said that she liked the taste of mud.

Ultima V: Lazarus
Afflicted by an unknown mental deterioration, the beautiful Jacqueline could barely remember her name, and seemed oblivious to her life on Waveguide, hardly able to converse with the hero. Jacqueline's heavily scarred husband Gregory sought to cure her affliction through human experimentation, subjects which Lord Dalgrin had been happy to provide. Enlor's apprentice Alfred, who had been in Buccaneer's Den searching for a certain tome by the wizard Ignap, had come to be incarcerated on the island. During his time there, Alfred and Jacqueline had become close, driving the jealous Gregory to kill the young scholar in his experiments, which had ultimately failed to provide a cure for his wife
