If you don't want to know the circumstances surrounding Wednesday's entry in this slideshow, then don't read any further...
[spoiler]Wednesday's quote:
Ep #480 (1968) - Barnabas - 'I won't call her but we MUST contact Julia. She's the only one who can get us out of this situation.'
From "#0479/0480: Robservations 05/13/02: Forget, Jeff, Forget!"
Barnabas gives in to Lang's threat to shoot and reluctantly hangs up the phone. He's shocked to learn that he can actually die now, which Lang assures him would happen if he pulled the trigger. It almost gives Barn pleasure to think he's THAT human. He agrees not to call Julia but still wants to bring her in, even though Lang continues to insist he doesn't want her to know about the experiment.

The Robservations doesn't get into the details of the quote but it does reference where and in what manner it takes place...
And this is the second quote from this ep. The first (Barnabas - 'You MUST let Clark live') was back on November 27th.
