Anton Lavey
If I am correct, in this movie there is nothing about Jayne being a priest of the Church of satan by Anton Lavey.
And that is a pity, knowing the fact that the satanic church was an important part of Jayne's life.
It's even the cause of her death: dutch satanist and direct pupil of Anton Lavey Maarten Lamers has admitted satanists have cursed Jayne when she kept on holding contact with a certain forbidden person.
Directly after she was cursed, she died in a car accident.
