If you don't want to know the circumstances surrounding Thursday's entry in this slideshow, then don't read any further...
[spoiler]Thursday's quote:
Ep #212 (1967) - Liz - 'Now you MUST promise to come whenever you like. You're not a stranger, you know-- you're a member of the family.'
From "#0212/0213: Robservations 10/19/01: Barnabas Uses His Charms"
Drawing room - You must promise to come whenever you like, Liz tells Barnabas, you're not a stranger, you know, you're a member of the family. Vicki enters, sees the stranger and apologizes--she didn't know Liz was busy.

And still while not a direct quote, the Robservations references the quote nearly word for word. We're really getting spoiled. But no doubt it won't last...
