Magnus, Madam Findley was played by Cavada Humphrey, who was memorable as Miss Flannery in Thoroughly Modern Millie. Hannah Stokes was played by Paula Laurence, who was a friend of Sam and Grayson Hall. When I saw Madam Findley, it seemed to me that Cavada Humphrey would have made a good Magda, but I don't have that feeling with Paula Laurence.
We've segued completely away from Cyrus's experiment. I guess it's on hold while he waits for Horace Gladstone to deliver a better batch of the magic chemical. It's the parallel time version of the interval between full moons.
I feel sorry for Alexis. According to what she says - and even if this woman is Angelique, it appears to be true, judging from how Hannah acts - Angelique was always the favorite twin of her father and her Aunt Hannah, and her mother (would that have been Professor Stokes's highschool sweetheart?), whom she appears to remember without rancor, is apparently dead. No wonder she went to Italy and didn't come back for years and years.
The plant that Alexis was pruning was, so far as I could tell, a chrysanthemum, which struck me as interesting because mums bloom in late summer and early fall, and this episode would have been taped in early spring. Also I thought chrysanthemums were associated with death, but Wikipedia says it's only white chrysanthemums that are symbolic of death, and only in some European countries. However that may be, I like the continuity between the pruning in Angelique's room a few days ago and today's pruning.
