Cuddy’s (Lisa Edelstein) innate chemistry and conflicts with Dr. Gregory House (Hugh Laurie) on HOUSE is one of the show’s most compelling ingredients. Edelstein explains how Cuddy has developed over the season’s existence.  HOUSE airs on Fox tonight at 8 pm et/pt, as the medical crew tries to cure a ballerina with a mysterious skin disease.
