Abigail is corrupting Trask. She's happy to use the Collins influence to bribe or threaten everybody to get Vicky hanged as a witch, an idea which apparently had not occurred to Trask before, What's Abigail going to do after Vicky is hanged, when she discovers that the world hasn't miraculously changed for the better?
In the interview with Sam Hall on an earlier DVD, he says they tried hiring a writer who wrote Barnabas as the Byronic type, with poetic lines galore, but it didn't work, because Jonathan Frid couldn't remember the tons of lines. I'm sure in my own mind that this was the episode that the poetical writer helped out on. The first scene, with Barnabas and Ben, comes across that way. Barnabas's violent anger at the innocent man who was digging Josette's grave seemed unlike him. Very Byronic, however. And then Ben said Josette's hand was white as marble. Since when did Ben think much about marble? With this in mind, I thought the whole scene was played out as if it Shakespeare. It was fun, and I thought to myself that I'd like to see Jonathan Frid and Thayer David doing actual Shakespeare together - but it would get tiresome if Dark Shadows were like that every day.
Peter Bradford's room was so obviously the same set as Angelique's bedroom that I had trouble believing that it was not at the top of the Old House.
