Brenda Chenowith
Played by Rachel Griffiths
Brenda is highly intelligent, highly protective of her emotions and highly skeptical of the possibility of being happy. She comes by her misgivings honestly: at the age of six she was declared a genius and placed in the care of psychiatrists who manipulated and scrutinized her every move. To make matters worse, her hell wasn't even a private one — it became the subject of a best-selling book titled, Charlotte Light and Dark.
