[spoiler]Thursday's quote:
Ep #1075 (1970) - Barnabas - 'Then something MUST happen to Hallie or David or somebody else before she'll even listen.'
From "#1074/1075: Robservations - 08/21/03: Lilacs"
That's the next clue, says Barn--the unfinished horoscope. I saw the finished chart in Liz' room, says Q. No disaster was mentioned? asks Barnabas. Completely the opposite, says Quentin, it states that Collinwood is to come under a siege of unrelieved tranquility. It must be unfinished, says Barnabas--where is Elizabeth? She went to Portland for a day or two, answers Quentin. I wish she were here, frets Barnabas, I want to tell her there's danger for the entire house.She would probably disregard the horoscope as having anything to do with the sun and the moon, predicts Quentin, and she'd also say it's not unfinished, it's absolutely complete. Then something must happen to Hallie, David or somebody else before she'll even listen, says Barn.
