5 - 1: Preserve the Romance

The curmudgeonly GP struggles to come to terms with his new role as a father, having planned to resume his career as a consultant in London before the arrival of his and Louisa's as-yet unnamed son. To make matters worse, he begins to have serious doubts about the competency of his replacement Dr Di Dibbs when she misdiagnoses a patient as well as herself. Martin is then dealt a devastating personal blow after hearing his aunt Joan has died.
