Marie-Hélène was hired by Emily's parents before Emily was born. When Emily was told that she was a half-breed, she committed suicide (Emily's Identity Crisis). Marie-Hélène continued to work for the family.
Emily's parents were being arrested for inter-species marriage. Emily's mother called to Marie-Hélène, "Marie-Hélène, HELP!!!" Marie-Hélène bit a police officer's arm. Another officer hit Marie in the head with a club, splitting her skull, killing her on the spot.
