Trivia: The piano piece Nick plays in this episode was composed and performed by Geraint Wyn Davies. He wrote it for his children, as an elegy to a pet bird that had died. (00:09:40)
Question: Two questions. 1. Was there some kind of contributing factor that made Nick want to be human again and if so what was it? 2. In one episode Janette is discovered to be human again. How did she accomplish this?
Answer: Nick was sick and tired of being an immortal bloodsucker. He wanted to be human, fall in love, get married, have children, grow old and die. As for Janette, according to her, she fell in love and the passion she felt "cured" her of her blood lust.
