[spoiler]Monday's quote:
Ep #675 (1969) - Barnabas - 'She MUST have delayed him until the moon was out, and then he couldn't help it. The werewolf does not choose his victims.'
From "Robservations 10/3/02 - #674/675 - Donna Friedlander, Bullseye!"
Barnabas surveys a headline in the COLLINSPORT STAR--"Mystery Murder." Julia and Barnabas feel responsible for Donna's death--if we hadn't let Chris take Donna with him, could we have stopped it? queries Julia. Barnabas doubts it--wherever Chris and Donna went last night was Donna's fault--she must have delayed him until the moon was up--the werewolf can't help it--he doesn't choose his victims.

The Robservations references the quote well though not exactly...
And this is the second quote from this ep. The first (Carolyn - 'The police took him about a half an hour ago, Mr. Garner. There MUST be something you can do!') was back on December 22nd.
