Zoe McCallister
Zoe McCallister was a newly qualified nurse who was due to start work at Northern District Hospital in early 2005. As far as the staff were concerned, she’d turned up, but the first hint that there was more to it came in Episode 3879, when Henry and Matilda discovered a burned body of a young woman in the aftermath of a bushfire. It was soon discovered that the woman had been killed prior to the fire. The next sighting of Zoe came in Episode 3915, when Peter discovered a photo of a young woman, in an abandoned van that had been used by the Summer Bay Stalker. He asked Hayley if she knew the woman; Hayley didn’t, but pointed out the photo showed her standing in front of the old Summer Bay sign destroyed in the fire. Peter deduced that she was the still unidentified burned body.
The truth was revealed in flashback in Episode 3952. On her way to Summer Bay, Zoe had the misfortune to end up staying the night at the same place as Eve Jacobsen, a psychiatric nurse who sought revenge on Summer Bay for the death of Sarah Lewis. On learning that Zoe was estranged from her family, who lived in Western Australia, and had no friends who would miss her, Eve saw a perfect opportunity to integrate herself into Summer Bay. She convinced Zoe to drive to town with her and then to stop by the town sign to have her photo taken. There, she killed Zoe and assumed her identity.
