Following a hold-up at the diner, Ailsa suffers a bout of depression and begins suffering hallucinations; in which she sees Bobby's ghost coming out of the fridge door. These visions are a result of expired anti-depressants from her post-natal period. Ailsa is later confronted by her brother, Tony O'Rourke (Daniel Roberts), who still harbours a grudge against her for killing their father. They eventually make their peace. Ailsa is later involved in a car accident with Duncan and ends up comatose as a result. The doctors consider switching off the machine but Duncan witnesses movements. Ailsa wakes up, but due to the brain damage she has suffered, her personality becomes cold and distant and she is resentful toward Alf for thinking of turning the machine off. Irene Roberts (Lynne McGranger) helps Ailsa get back to her old self.
