"Margaret" died in 1966, not 1967.
In this and especially in the next episode, I think, everybody gets smarter and more knowledgeable. Marmorstein? Well, Guthrie doesn't get smarter... Guthrie wants Carolyn to suppose that reincarnation is real. Then, based on this assumption he asked her to make "just because", he asks rhetorically, can we not also suppose that it happens as it does in the phoenix legend? Yes, says Carolyn dutifully. There you have it, logic is whatever an "expert" says it is! Roger needed to walk in then, and say something like, could we not also suppose that Druids from beyond Neptune cause reincarnation? We can suppose anything we like, I guess!
Lasell looks at teleprompter, and I catch him.
Joel Crothers can really add reality to the story, as Selby and Clarice B can. JC gives us some very intense looks, where you can tell the character's thinking, and/or feeling dread of some kind. Yet, the character never get overtly emotional. No displays, no yelling, nothing showing except in the eyes, and somehow we see deeply into the character to where the emotion's buried, without it showing in facial expressions.
