[spoiler]Thursday's quote:
Ep #555 (1968) - Nicholas - 'No, that is out of the question. You MUST STAY here.'
From "Robservations 7/10/02 - #554/555 - Guess Who's a Vampire Now?"
Vicki sleeps. Adam watches her. Nicholas returns and says he can take Vicki away now--my house isn't far, he says, pleased that Adam used the drugs he gave him. Vicki will sleep several hours, says Nicholas, and will awaken in her new hiding place. She won't know where she is. Don't harm her, demands Adam, and Nicholas promises she won't be if Barnabas cooperates. Adam wants to come along, but Nicholas refuses--you must stay here. Adam wants to go to ensure Vicki's safety. You must trust me, says Nicholas. Adam continues to insist, and Nicholas says it would be a problem if he disappears from this room--Carolyn would immediately suspect Adam was connected with Vicki's disappearance and call the police.

A least the Robservations references half of the quote quite well and the rest adequately enough...
