Youre a well known exorcist called in to deal with a case. The worst they'd ever seen, according to those involved.
You arrive at an inconspicuous looking house and greet the daughter of the victim who seems unhappy about your presence. The other people involved seem happy to see you, and guide you to a room at the back of the house where the increasingly loud yelling sends a shiver down your spine.
At the beginning, you can get through to the person underneath, and at times of lucidity they are sweet, and kind, and so sorry to be a burden.
Over the course of a week you work hard to figure out how to expel the demon, who seems to be increasingly angry. Violent threats of rape, murder and abuse are thrown at you constantly, the language used is disgusting and at times causes you to cringe and leave the room.
The daughter visited at first, having plesant conversations and almost looking happy to speak, but as the demon takes more control, she refuses to enter the room. You stumble across her sobbing in her room one day, but decide not to intrude and leave her be, for you'll fix it soon enough.
It is the 8th day that you finally figure out what to do. You gather everyone available to help perform the exorcism, with the exception of the daughter who refuses to enter the room still.
As you chant your final line and your patient screams in pain, you feel a sense of fulfillment..... Until the laughter starts. You make eye contact and dread fills you as the face that meets yours twists into a nasty smirk. You leave the room as the screaming grows louder and the threats more violent and sickening.
Looking up, you meet the wet eyes of the daughter, who openly weeps now.
"I'm sorry, I couldn't exorcise the demon. Youre father is lost"
The look she gives you could turn fire to ice, and the words she mutters makes you feel as though the earth has opened up and swollowed you whole.
"your exorcism worked, that is my father."
