Kathy's mother was murdered by her husband David. At a banquet, Kathy was seduced by Derik (David's second son), who then poisoned her and subjected her to brutal abuse. She eventually married Derik. It was only after entering David's household that Kathy revealed her true nature—she was plotting revenge! Shawn (David's eldest son), who had survived a car accident in his youth, had been living in hiding as a disabled man.
