Rosanna Arquette is very calculated, not mentally ill, and knows exactly what she is doing.
Wikipedia: Arquette was born in New York City, the daughter of Brenda Olivia "Mardi" (née Nowak; 1939–1997), an actress, poet, theater operator, activist, acting teacher, and therapist, and Lewis Arquette, a film actor, screenwriter, and producer. Her paternal grandfather was comedian Cliff Arquette. Her mother was Jewish, from a family that emigrated from Poland and Russia. Her father, whose family's surname was originally "Arcouet", was of part French Canadian descent. Her father was a convert from Catholicism to Islam; through him, Arquette is distantly related to explorer Meriwether Lewis. Her siblings, Richmond, Patricia, Alexis, and David, all became actors as well.
