I don't have much on this ep. either.
Humbert Allen Astredo does the opening voice-over, his first--and very nicely too, at least according to my notes.
Cassangelique forces Willie to come to her at the gazebo and hypnotizes him into doing her bidding. After she leaves, Nicholas materializes, but without any puff of smoke. Just to be mean, he shortens Cass's deadline from midnight to 9:00 p.m., just one hour from now.
David is desperate enough to get someone, anyone to listen to the tape that he asks his step-aunt. Naturally, she gives him the brush-off, so he goes off to bed. But he pauses on the stairs, turns around, and asks her, Do you know very much about Barnabas? Do you know what his affliction? Now David has Cassandra’s undivided attention. Grabbing his arm, she propels him back to the drawing room. He’s even more surprised when she tells him, Hurry! I want to hear the tape. The tall clock in the foyer now reads 8:58. He tells her, There's music [we gather he thinks Mozart is boring], then some strange talking. Frantically, Cassandra tells him to fast forward to the talking. She is even more astonished than David was to hear Eric Lang's last, desperate warning to Julia. The music resumes, so David turns off the recorder. Do you know what it means? he asks. Adam … Barnabas--of course! she exclaims. What do you know about Adam? David asks. It's now about 8:59, so she orders David to go to his room quickly, nearly hysterical. As the clock strikes the hour, she screams again and again for Nicholas.
