Was that Ken McEwen doing the voiceover? And if so, shouldn't he have been wandering around the episode looking for a beautiful bitch to suck the life out of him?
So. Daphne was, according to the records, a governess who died in 1841. That's open to question: as Julia pointed out a few episodes ago, the truth can be altered in family histories. But what Hallie said today, when she was possessed by Carrie, can be taken as fact, I think. So we know that Gerard had a ship, and that one day he and Daphne kissed on it, and that nobody was supposed to know. We also know that Carrie went to the ship alone to explore, thinking that nobody was there. This makes Carrie sound more like Amy than like Hallie, and it really makes Carrie sound either quite naive or else quite reckless. We're talking about 1840 or 1841, after all, when young girls weren't supposed to do things like that. She thought nobody was there, but what if a rough sailor had been there and had taken sailorly advantage of her? But I don't think the writers have any intention of making Carrie into a "fast" (to use the word in its old-fashioned sense) young woman.
Assuming that, in the original events, Carrie did go onto the ship and she did see Gerard and Daphne kissing and she was caught seeing them kissing, and punishment was the next step...did she get punished? Was that one of the events that led to Gerard and Daphne being unrestful dead? And did Daphne change her actions the second time around? Or did Daphne relent the first time around as well?
