Golly, what a strange conversation between Quentin and David: each of them knowing that Daphne had been there in David's room, and each of them determined not to let on. And, of course, it was made all the stranger by the fact that once, not too long ago, Quentin, or anyway his ghost, was the one doing the haunting. Quentin doesn't remember that, and David shouldn't, but David does. Or anyway, he did before Barnabas went into parallel time. There's no telling what he remembers now.
Maggie was funny at the picnic. You could hear that she was talking with her mouth full. How nice for Kathryn Leigh Scott to play a damsel who's not in distress!
And then later on, Maggie was unintentionally funny when she said to Quentin, "It's futile to love someone who's dead." Oh, gosh, she has no idea (because she can't remember it) how much trouble she would have been spared if only Barnabas had felt that way!
During that same conversation, Quentin talked about the Quentin who lived in 1840: same name, same house. And that's Dark Shadows in a nutshell: Collinses at Collinwood, whatever the year, whatever the time band. Yeah, I know, Quentin meant Quentin Collins at Collinwood. Never mind. I still hope Joe Caldwell smiled as he wrote that line.
