Hayley changed her career, becoming the host of a television style show called Wave. As Mateo and Hayley planned to get married – for real – a whirlwind named Arlene breezed into town. Arlene crashed Mateo and Hayley's wedding reception with the news that she and Adam had gotten married. Arlene continued to insinuate herself in Hayley's life. 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. Arlene declined the offer, but after she miscarried she called Hayley to Chandler Mansion with the claim that she had reconsidered. Hayley arrived at the mansion just as her mother had taken a tumble down the steps. Everyone believed that Liza had caused Arlene to fall down the steps and that the fall had killed the baby. Hayley was crushed because it was yet another blow to her desire to have a family. Hayley and Arlene had a showdown on Halloween 2000 in which Hayley told her mother to get lost – and to never come back.
