It's easy for me to forget how interesting this storyline is when I'm not watching it, because so much of it is not about words, and not about reason. Quentin is still very much himself, and he knows what Barnabas and Julia have told him about 1995, but he is still enslaved by Daphne. David must know by now that what he is dealing with is serious and dangerous, but he's not telling anybody. And we can assume that Hallie, scared though she is, is not telling her Uncle Eliot anything. She is out of the Collinwood and off of the estate - off of the territory of Gerard and Daphne - but she's not saying anything. Maybe, now that she's away from it all, she thinks it was a dream, or she thinks that her uncle will laugh at her if she tells him about it. Or maybe she just can't tell.
If, in December of 1968, Barnabas and Julia had found themselves in 1993, and found that David was dead and the rest of the Collins family spread to the four winds, and if they had then come back to 1968, would they have had as hard a time as they are having now?
I like the development of Daphne preparing to knife Quentin. It tells us that, even having been to the future, we don't know everything about what will happen. I'm wondering if Daphne's idea is that they'll be two loving ghosts together. Alternatively, love has nothing to do with it, and she's opposed to Gerard and looking for a ghostly ally. Or else she just likes killing people.
