Lux Cassidy is a fictional character and one of the protagonists of the CW television series Life Unexpected.
Lux was born with a congenital heart defect and spent the first few years of her life in hospital due to various surgeries she needed.
For several years thereafter, she was either fostered out (with the people only doing it for the state check, none of them caring for Lux at all) or living in a place called Sunnyvale.
She tracks down her birth parents Cate Cassidy and Nate Bazzle in order to get them to relinquish their legal rights so she can get emancipated from foster care.
Sadly, Lux is refused emancipation by the court and is instead placed into the custody of Nate (Baze) and Cate temporarily.
Cate and her fiancé, Ryan Thomas, who worked with her as morning drive time radio disc jockeys, make up their attic to become her bedroom.
Eventually, Baze and Cate are granted permanent custody, thanks to the aid of Lux's social worker.
In the beginning of season one, Cate pulled Lux out of Longfellow due to a gang fight that had occurred there.
Nate aka Baze later starts to work at his father's company and ends up meeting a woman named Emma.
Lux then begins a secret relationship with Eric Daniels, a man she meets at the Open Bar, which her father operates and later owns, who is later revealed to be a teacher at Westmonte).
At this moment Lux thanks her dad for a lot of good things that happen in her life since she met him and apologizes for telling him about Emma.
The final scene of the series takes place two years in the future and shows Lux giving the valedictorian speech at her graduation.
