Well, we got the solution to "Who Killed Angelique?" and of course it turns out that the butler did it. Or anyway, the man who was played by the actor who played the man who believed for a while that he was a butler did it. Very pleasing, though points are deducted because Inspector Hamilton didn't explain it all in the drawing room. Maybe he will do so later on, but it won't be the same, now that we know whodunit. And of course further points are deducted because Bruno's murderer isn't the same person as Angelique's murderer. I don't like messy mysteries. I realize that it would have been difficult for Angelique to murder herself with a hatpin (unless she asked for Quentin's help, the way wives ask husbands to zip up their dresses for them), but I would very much like to learn that Roger had it in for Bruno and remote-control killed him just a fraction of a second earlier than Angelique tied her knot.
All that aside, parallel time Roger's murder of parallel time Elizabeth is among my favorite moments on Dark Shadows. I wish it had been executed better, but the very fact that it is done is quite satisfying. I also wish we could have seen our-time Roger and Elizabeth talking amicably together sometime after that, but we've already had our last our-time Roger appearance, alas.
I'm still not clear on why Roger killed Angelique. That's sort of how things go in parallel time, I guess.
Another favorite moment is when Julia blows out one of the candles. Clearly it was planned ahead of time; the two-hole candlestick isn't carried around much. Usually it's a either a one-holer or a whole candelabra. When Julia calmly rations her candle use, we are plainly shown Julia's superiority to both of the Maggies.
(Addendum: the spellchecker accepted whodunit but rejected one-holer. Interesting.)
