It's Essie's first day in her new role as transplant co-ordinator, so she's thrown when Sacha asks if she meant it when she told him she wanted a baby – or was that just the wine talking? Essie and Sacha's attempt to avoid the issue is not helped when Sacha has to treat an exhausted mother, Roxanne. As the day goes on, Sacha's curiosity regarding Essie's future plans grows - and when he sees her deep in conversation with obstetrician Mr T his imagination runs riot!
Sacha admits to Essie he’s worried that their visions for their future together are too different but, later, inspired by Roxanne, Sacha tells Essie they should try for a baby - if that's what she really wants. Will Essie let Sacha make such a personal sacrifice to satisfy her own needs?
