Kieffer (from Series 4 "Invasion") returns in this episode, and we learn of his wife and two children. Also returning are Foyle's son, who had been flying in Malta prior to his discharge, and Pierce (from Series 2 "War Games" and Series 3 "The French Drop"). With the war in Europe winding down, Foyle is retiring again and the station is being moved to another location. Milner received a promotion to DI and a transfer to Brighton, while Edith, his new wife, is expecting their first child, a daughter. When the delivery starts, Foyle gets behind the wheel and drives them to the hospital. Stewart is uneasy about her post-war career, and Foyle suggests volunteering with the military charity SSAFA. Andrew Foyle attempts to apologise and propose to Stewart and rekindle their friendship and romance.
