Not usually known for his sensitivity, John Forrest was a pushover where Liz Kennedy was concerned. He planned a day out in Melbourne where he surprised Liz with a pre-planned marriage ceremony. Their marriage was pretty short even by the standards of The Young Doctors. On their return to Sydney, Liz was electrocuted and killed by a faulty lamp in John's house. Forrest never really got over Liz, despite attempts at relationships with Tania Livingston and Dolly Davies, amongst others.
