Zoe is the wife of Mal and the adoptive mother of Brooke Hathaway and Oliver Morgan's son, Thierry. Zoe and Mal arrived at the hospital after Thierry was born and promised Brooke and Ollie that they would love and look after him. Ollie gave them a memory book so Thierry would know who they were, but Zoe and Mal left it behind after they left the hospital with Thierry.
In May 2022, Zoe and Mal brought Thierry to meet Oliver, Brooke and Luke Morgan as Oliver wanted the "perfect ending" for Luke, who was dying from frontotemporal dementia.
