[Wikipedia] Lost Girl is a Canadian supernatural crime drama television series that premiered on the Showcase Television network in September 2010. The series follows the life of a succubus named Bo, played by Anna Silk, as she learns to control her abilities, help those in need, and discover the truth about her origins. The first season of Lost Girl premiered in the United States on the Syfy network in January 2012.
In the pilot episode, Bo saves a human girl named Kenzi; the two quickly become friends and Kenzi decides they should team up to create a Fae/Human detective agency. Confronted by the Fae elders with having to choose a side (“Light” or “Dark”), Bo declares herself neutral, deciding to side with humans after Kenzi risked her life to find what had happened to Bo for her own sake where most of the Fae simply saw her as another factor on the board. Throughout the season, Bo learns more about the Fae world and herself while she searches for information about her origins. Along the way, Bo also develops romantic relationships with both Dyson, a wolf shifter police detective and Lauren, a human doctor.
