Does anyone know what really happened at the end of "The Stuff of Dreams"? I listened, but I was really confused by the ending. All I know is this girl worked for an older lady, who had some sort of rape fantasy about the girl's boyfriend. She invited them over and showed him her bedroom. Then comes the confusing part....

He goes out into the hall to talk to his girlfirend (more like an argument) and then he goes back into the bedroom and locks the door. The older woman is trying to be amorous and she's convinced he's going to rape her, which turns her on for some reason. Then he lights a match and she is shocked to see his face for some reason I'm not clear about. Then there is a fire and the girlfriend is outside banging on the door. What I am not clear about:

1. Did he start the fire on purpose and did the woman die, or did his girlfriend die? Which one was he trying to burn?
2. Was he supposed to be the devil, or one of his helpers?
3. Why is the older woman alive at the end, or is it her sister or someone else talking? The voice sounded exactly the same, so I am assuming it's her. How did she survive the fire?
4. What was his intention? To rape her, as she believed he would? Or did he want to burn the house down?
5. Was the girlfriend alive at the end? For that matter, was the man alive at the end, or did he just vanish?

I have no clue what happened, so if anyone can fill me in on the details, I'd appreciate it. I didn't hear the show from the very beginning, so maybe I missed some important elements of the story. In any case, I am hopelessly confused about who did what and what was supposed to have happened at the end. (smile)
