If you don't want to know the circumstances surrounding Saturday's entry in this slideshow, then don't read any further...
[spoiler]Saturday's quote:
Ep #839 (1897) - Quentin - 'I MUST do it, I MUST!'
From "Robservations 3/5/03 - #838-839 - Julia, Prisoner of Petofi!"
Quentin stands outside the rectory, thinking to himself, "That's where Barnabas is--where he waits for me--can I betray him? A wolf howls. What if I don't? Petofi...I'll leave Collinwood, he'll never find me, all will be different, and Barnabas safe. And I, what will I, Quentin, be? He hears a rustling in the woods and looks away.
Quentin looks up and sees a hideous wolf's head staring back at him. It disappears, but--I know I must do it, I must! He goes on.
[/spoiler]
The Robservations references the quote well with the exception of adding "I know" before it, which is something Quentin doesn't actually say...
And this is the second quote from this ep. The first (Quentin - 'You MUST TELL me!') was back on June 29th of 2020.
