In Vampire: The Masquerade – Bloodlines, the two "sisters" Therese and Jeanette Voerman are revealed to be the same person: Therese was the original personality, and Jeanette was a sex-obsessed personality created so that Therese did not have to consciously experience being repeatedly sexually abused by her father.

The resulting supernatural psychosis caused her personality split to worsen, each side becoming a wholly fleshed out consciousness, with "Therese" being cold and repressed, and "Jeanette" getting the hyper-sexuality and Borderline Personality Disorder.
