Yesterday Carolyn, today Mrs. Johnson...who will be next on David and Amy's little list?
The kids sure are creepy. My idea of possession is always: somebody else's spirit (or something) takes over you, and you're not aware of what's going on. Come to think of it, that sounds like what goes on at the standard Dark Shadows séance, in which at the end somebody says, "What happened?" But David and Amy are aware of the possession and they're willing partners - although Amy, at least doesn't understand exactly what's going on, or she wouldn't have said afterwards, "I don't feel like Beth anymore." David is evidently more under Quentin's control than Amy is under Beth's. I'm not sure if there's any David left in there. It seems strange to me that David is more susceptible than Amy, but maybe Beth just isn't trying.
What must it feel like to take another spirit in as senior partner in your mind? Put that way, it sounds something like being under a vampire's spell.
What an odd conversation for Quentin and Beth to re-create! Why on earth would they want to remember it? I'm wondering if they had any choice in the matter.
