[spoiler]Monday's quote:
Ep #449 (1796) - Countess du Pres - 'Then...then I MUST accept.'
From "#0449/0450: Robservations 04/19/02: Joshua Tries to Make it Right"
Barnabas isn't dead, which puzzles her. He doesn't understand himself, says Joshua. She wants to see Barnabas--why did Josette jump if he is alive? Joshua refuses to let her see him, reopening her sorrow. He needs her help. This surprises her. Naomi doesn't know, says Joshua, and it would be cruel to tell her. How has he changed? demands Naomi. He's under a curse, reveals Joshua, and again asks for her help. Joshua tells Natalie Miss Winters isn't the witch, and Natalie guesses Angelique--Peter Bradford told her that, too, so she must accept it.
[/spoiler]
The Robservations references the quote well, though it frames the quote differently from how it actually plays in the ep. Countess du Pres does mention that Peter told her Angelique is the witch, but it's not that she must accept it because Peter told her, it's after Joshua insists it's true...
