Barnabas hypnotizes Nora into forgetting him in the gentlest way possible. He must feel that somehow Sarah is watching him. (I know, I know, sentimental!)
Is that how "Azhden" is spelled??
I also love the cave, MT. Your crumpled-black-paper hypothesis works for me. The overwhelmingly green interior sets are a bit tacky, but I've always loved the trees, which look very real and beautifully made.
I guess now that Barnabas is safe in his bat cave, he can afford not to have Charity as a host. I'm sure he had fun fooling her father, but even Barn now realizes that Worthington Hall is too hot to hold him--although of course the end of the ep. tells us that he realizes this much too late. His motives for trying out the hand on Charity seem highly questionable to me.
Everyone in the Collins universe should realize that letting any character played by HAA get the last word is never a good idea. Barnabas has had to return to the cave and is opening his coffin when he hears a sudden noise. Magda? he calls, then exclaims, It is you! he exclaims. Before him stands Evan Hanley. He is wearing a large gold cross on a chain around his neck, and he holds the cross in front of him. Good evening, Mr. Collins! he says with taunting politeness. Or should I say, Good morning?
