[spoiler]Yesterday's quote:
Ep #288 (1967) - Vicki - 'Well, listen, I know that you like to imagine scary things, and you have a very active imagination, but you MUSTN'T let it run away with you.'
From "#0287/0288: Robservations 12/17/01: Julia KNOWS!!!"

Except for the part in which David says he felt that Vicki looked so strange, everything else in the Robservations summary actually happens in the teaser, but it was necessary to include it for context because of the way the summary is written. And in Act I what isn't summarized is that after David says Vicki looked strange, he says there was something scary about it, and Vicki replies with the quote to that remark...
