When Arlene revealed that she was pregnant, Hayley and Mateo came up with the idea of adopting Arlene's child. That would allow them to have a child of their own and it would spare the baby from having to grow up with Arlene as a mother.

He tracked her down to an exotic island in the Caribbean and hauled her back to Pine Valley just in time to prevent Hayley from confessing in court that she had killed Arlene. Arlene was ordered by Adam to sign off on their marriage and leave town – never to return again. On February 21, 2001, Hayley learned from a psychic visiting Wave that she
