Roger remarks to Cassandra that if the large, grotesque stranger hadn't been moving around and making grunting noises, he (R.) would have imagined he was dead. A walking dead man? Cassandra asks innocently--although we know she already has met (and married) at least one walking dead man.
Maybe Julia is trying to scope Cassandra out under the guise of forming a friendship with her. This is her chance to get to know the woman who so nearly destroyed the man she (J.) loves.
Barnabas and Julia do a 180-degree turn in their attitude toward parenting. Barnabas has given up the search and returned to the Old House, where he and Julia meet up. The logical Julia concludes, Adam has probably gone home--just as a small child would do if he were hurt. (They took long enough to make up their minds that I wondered why they didn't just go downstairs!) Barnabas is skeptical but when they go downstairs, sure enough Adam is there. He's hostile at first, till Barnabas gently reassures him that they want to help. Then he lets Julia (who has suddenly gotten sympathetic) treat his wound--it's just a scratch. Barnabas wants to go to Collinwood to somehow talk Roger out of having the police search the Old House, but Adam gets upset when he makes to leave. Julia has to explain some of the finer points of parenting, and Barnabas promises Adam he'll return soon. He's still very pleased with Adam's progress. I think you'll learn very quickly, he tells Adam encouragingly--and even proudly.
dom, you are absolutely right about Robert Rodan. He is amazingly good, and his final scene--where he learns his second word--is just beautiful.
