An Attractive Visitor (S02E06)

During a holiday, the Parkinsons befriended Susanna, who is now visiting them. Ria picks her up from the train station, and while heading home, Ria stops at a store. Leonard spots the car and approaches, introducing himself to Susanna. Once they return home, the men are enchanted by Susanna, who revels in the attention, much to Ria's annoyance. Later, Leonard calls and proposes a weekend getaway to Birmingham with Ria, but she turns him down, playfully suggesting he take Susanna instead—an idea he happily embraces.
