Good episode, with some excellent scenes for Louis Edmonds.
I think the railroad station set is a re-using of the back door of the Old House - unless the back door of the Old House is a re-using of the railroad station set used in episode 1.
I wasn't really impressed with KLS's strangling technique. Angelique didn't appear to be in any great danger. Oh, well, maybe Kitty will improve with time. But actually, Angelique couldn't have been in any danger anyway. I assume that when Quentin said he was hoping Kitty would kill Angelique, he was speaking rhetorically. He knows where Angelique comes from, and he knows that it takes more than a good strangling to finish her off.
Back in 1795, when Barnabas confronted Angelique about her witchhood, she said that their marriage would turn out just fine. I think she probably said that Barnabas would grow to love her. If she didn't, I'm sure it was indicated. And here she is, doing the same thing with Quentin.
What is Angelique's surname in 1897? I could have sworn that Edward introduced her to Victor Fenn Gibbon as Duval, and today he introduced her to Kitty as DuBois.
Kitty's great. Here she's got really scary stuff happening to her, and instead of running away from Collinwood she's using the weird events to reel in Edward. I'm glad she wrote her mama a few episodes ago that Edward was a dear, because she brings out the best in him, and I'd hate to think that she might turn around and (like Angelique with Barnabas) start in with the unpleasantness as soon as they're married. It helps, of course, that Kitty's not in love with Edward.
