Lexa was the wife of Hank Hardwick, the porn star patient in the Season 6 episode Teamwork. She was portrayed by actress Jolene Blalock.
Lexa, like her husband, works regularly in pornography. Like her husband, she strongly defended her lifestyle choice and insisted that she could separate the merely mechanical act of sex with the love she had for her husband.
However, when the doctors felt Hank had a disease that meant he couldn't risk having promiscuous sex, she was supportive and asked him to stop. However, Hank was resistant to the doctors' diagnosis, feeling they had jumped to a conclusion because they disagreed with his lifestyle.
