t's Martin's last day in Portwenn and the surgery is packed. Edith turns up, expecting an apology from Martin for walking out on her but of course does not get one and Joan again rebukes him for distancing himself from his child. As he is about to leave, Tasha, a school-teacher friend of Louisa, collapses. She has been inhaling fumes from an illegal bio-fuel used by her cab driver husband Tommy. She is all right but Tommy, who is driving Louisa to hospital for the birth, also collapses at the wheel and crashes the car. Martin races to save him and to help deliver the baby. It's a boy, and the whole of Portwenn, who have been listening via Pauline's amplified mobile phone, cheer Martin and Louisa and their new offspring.
