Liz’s parents were academics and born-again Christians. She rebelled against their ideas by choosing not to go to university and plumping for nursing training instead. It didn't help the already strained relationship between them and she hadn't spoken to them for years.
She met John Beresford, a builder, when she was working as a senior staff nurse in Holby's geriatric ward. They moved in together and he set up his own business. By then she was finding nursing restricting, and thought there would be more of a challenge and more variety in the work of a paramedic. Liz certainly likes the relative freedom, likes driving the ambulance, likes using her initiative, and the patients like her cheery efficiency. But John begins to put pressure on Liz to start a family. She asks Josh about her prospects and he assures her she is doing fine so she decides that babies will have to wait.
