The characters of Gavin and Stacey provide the emotional core of the story, focusing on the situations that arise when their relationship brings their two different families together. As a result, episodes often focus on the key events in life that bring wider families and close friends together such as weddings, christenings, birthday parties and Christmases. However, the show also presents the families interacting in deliberately non-dramatic situations, such as a visit to the beach and nights out. In these scenes, the subtle dialogue between the characters often contains underlying jokes or comedic value.
