Not to be a wise guy, but for accuracy and all that, I'll say that I think your remarks are for #643, DL, good though they are... I never thought of its being Magda warning the kids, but then we don't know about another female ghost yet.
So David, you can't let apparent threats like a grandfather clock almost injuring you stop you from getting to Quentin's room? Why is that exactly? When did this stop being fun and become a holy mission? Is David under Q's control already, despite not being able to talk to him? Some comeuppance for David, getting trapped in a West Wing room after having done this to Vicki early on. Nancy Barrett's good. She puts herself totally into things, such as her psychic dream about David and Amy being in danger. Why was the unexplained name "Jamison" ghost-fingered onto Carolyn's mirror? What about him? By whom? Too bad Roger doesn't tell us anything about his father, such as when he died.
Welcome, Quentin's favorite record. Roger forgets about the Drawing Room secret passageway he used in 1966, but then I forgot he'd used it too. Amy, clever plan for getting let out of the room by their elders, while still not being caught by them! Too bad Q wouldn't allow it. That door to Q's room should have been bricked up....
