[spoiler]Wednesday's quote:
Ep #601 (1968) - Julia - 'Yes, Nicholas stopped it. He MUST have been there when the... when the spirit attacked Adam and he MUST have used his powers to drive the spirit away.'
From "Robservations 8/12/02 #600/601 - A Chilling Summons"
Nick warns the spirit it will be consumed by the eternal fires of hell as both Barnabas and Adam announce that they can't breathe. (yet they can talk!) Nicholas succeeds in banishing the spirit; Adam can breathe, as can Barnabas. Adam assures Nick he's all right. He doesn't understand what happened. Barn tells Julie the pain is gone; he has no idea what happened. Nick promises Adam it will never happen again, but won't explain how he stopped it--rest, Nick urges Adam. Julia tells Barnabas Nicholas stopped it--he must have been there when the spirit attacked Adam and used his powers to drive away the spirit.

Even though the Robservations doesn't reference the quote word for word, it does reference it quite well...
