Lydia Deetz is the daughter of Charles Deetz and the step-daughter of Delia Deetz. Lydia is a serious but kind girl who is sensitive beyond her Goth dress and feels isolated in the world. Her father and stepmother do not take anything she says seriously and often ignore her for their own selfish pursuits. Lydia loves writing poetry, taking photographs, and loves anything pertaining to the supernatural and paranormal. Despite her young age, Lydia appears to be the most sensible member of the Deetz household. Though in her dark personality she has a great dark sense of humor to her. She also has a certain flair for the dramatic, particularly when talking about herself. ("My life is a darkroom. Just one. Big. Dark. Room."). By the end of the film, she is more happy and well-adjusted because Adam Maitland and Barbara Maitland become active parental figures alongside Charles Deetz and Delia Deetz, who take a stronger role in her upbringing after having seen her nearly forced into marriage with Betelgeuse (Beetlejuice).
