I keep wondering about that music box myself, lori54. When Barnabas first has Maggie listening to it, its function seems to be just to induce a mood, but as time goes on, it seems to gain power. In the episodes I've watched, I haven't seen any attempt to explain it, and my impression from what I've read here is that no attempt is ever made.
One of the great sorrows of my life as a Dark Shadows fan is that, although I love the word jasmine, every time I smell jasmine, I don't like it. Maggie says it smells sweet, and I like sweet, but jasmine never comes across that way to me. If I were Dr. Hoffman, I would be wondering if it was chloroform that Maggie remembered, since in the thrillers that I've read, chloroform is always mentioned as smelling sweet.
I'd like to know what Dr. Hoffman's plans are at this point. Previously when we saw her, her sole concerned appeared to be for her patient. In this episode, however, things appear to be changing; she's pushing Maggie to go to the cemetery. She always knew what Maggie's blood looked like, so what is going on in that elegantly coiffed head of hers?
As for Vicky starting to lose intelligence at this point - having watched episodes 1-18 (still haven't gotten around to watching the rest of the DVD set), I am surprised that anybody thought Vicky ever had any intelligence at all. Is there an arc maybe? A Flowers For Algernon sort of thing, with Vicky starting out stupid, gaining intelligence in the first year to the point where she's a functional human being, and then losing it again?
