I was going to mention some continuity problems, so this seems a good place to add them.
First, the obvious kind - at the end of the episode with Elizabeth's dream and it's "repeat" in the next episode. In Robservations, Robin says Carolyn was in nightclothes in the one and fully dressed in the next. I didn't realize that one (!), but Elizabeth was wearing a light blue robe and there was a green blanket the first time. When they replayed the scene at the start of the next show, she was in the bright red-pink and had "Maggie's" colorful afghan.
Why was Barney musing about the vampire disappearing after Tom Jennings, when in yesterday's episode he made it so obvious that he knew Joe was under one's power? Can't the writers remember the script from two days ago? Why didn't Barney just leave when Joe told him to and then spy on him?
That was one I had thought about. Barnabas really seemed to suspect what Joe's problem was when he was at the house with him, but now seems to be totally puzzled by the lack of any other vampire victims.
I also found the Evans' painting to be rather funny. Maggie showed that she had it all wrapped up for Nicholas at the time that he wrote the check for $2000. Apparently Joe's surprise entry threw them all off. So, he said he'd come for it at 5 the next day, at which time Maggie shows him that she has it ready (he clearly already knew that from the day before!).
Stokes really surprised me today. The other day he tells Jeff that he knows all about the experiment and that he knows that Jeff is working on it - Julia had told him. They then have quite a dramatic scene with Adam followed by Stokes following him to Collinwood to try to talk him into returning to work instead of going out with Vicki. Today he seems to be surprised that Jeff is working with them. I wondered if there could be a reason that he was pretending for Barnabas, but that not only doesn't make sense, but some of the things he says to Jeff would imply that none of the previous events had happened.
