The writers mess with our heads a bit by having a shadowy figure open the upstairs hallway door while Carolyn and Dr. Guthrie talk. But it's only Vicki, who joins them in the drawing room.
Frank Garner calls Roger Roger, but Roger addresses him as Garner (without the "Mister"). I'll bet Frank doesn't call Elizabeth Liz! And we get our first look at what is referred to as Roger's study, although I'm also willing to bet he studies brandy there more than anything else. It would have been nice for Elizabeth to have a study of her own, but as the series went on, I did get very fond of that little writing desk in the drawing room.
We get a little more info on Carolyn's legal status as Frank tells Roger, "Because Carolyn is still a minor [we’ve already established she’s about 18], she is a ward of the trustees of the business. She can’t make unilateral decisions, but she is in effect the mistress of the house." Roger is disappointed, and even more so when Frank says he trusts Dr. Guthrie.
Carolyn is so desperate to see her mother that she tells Frank to book her a plane ticket to Boston. That's not really in his job description. But then again, with Elizabeth never leaving the grounds for the past 18 years, I guess the family doesn't have much use for a travel agent. And Carolyn doesn't seem to have gone much farther afield than Bangor. I thought Carolyn's despair and sorrow over her mother's plight were very touching. But because this was a Thursday episode, of course she comes around and tells Dr. Guthrie to go ahead with the séance.
I also liked it that Dr. Guthrie got the last word with something like, "I’m actually frightened of success. We could unleash a force so powerful, we may not be able to control it!"
