I hope that were I to find myself in that position, I'd have the sense to say, "Oh, deary me, I don't know what happened, and I don't understand it at all! Please, Miss Abigail, burn those clothes and PRAY with me! Oh, Reverend Trask, please PRAY for me!"
The clothes part always gets me. "I'll need those clothes!" She knew that she had other clothes to wear in 1967, and she could reasonably assume that if she ever got back to her own time, her friends would not reject her for temporarily wearing strange clothes - so why couldn't she let that one outfit go?I still maintain, however (until the next time I watch 1795), that Vicky thought she was in a nightmare - literally - so she though it was OK to say all the stupid things that she said.
If she is smart enough so see the difference in the Old House. Barnabas dressed in strange clothes. (that is not his costume from the party) Sarah being alive. It would have been interesting to make Vickie smart here. Maybe she would have thought about Angelique being the witch.
I liked the way the revival series handled the clothes issue. I haven't seen it since is originally aired, but IIRC, Abigal is examining Vicky's dress and finds the cleaning instructions tag, with reference to using a "cool iron" and the washing symbols that she thinks are witch's sigils or somesuch. Very amusing.
I, too, have wanted to see the Revival Series for a while. I don't want to pay too much for it. I'd like to get it real cheap so I can watch it and resell it if I don't like it. I'm willing to wait a few more years until I can find it dirt cheap, I'm not pressed to watch it.
