If you don't want to know the circumstances surrounding Friday's entry in this slideshow, then don't read any further...
[spoiler]Friday's quote:
Ep #1197 (1841) - Quentin(reading) - 'For Tad's sake, you MUST know the truth.'
From "#1197/1198: Robservations 12/08/03: The End of 1840/41RT"
Collinwood - Bags are packed, waiting in the foyer. Quentin exits the drawing room with a note from Samantha (don't ask me how that happened) the contents of which he dubs "beautiful:" "Dear Quentin--I've done you a great injustice in regard to Tad--whatever else went wrong between us, it didn't involve Tad--I lied to you, he is your son--for Tad's sake, you must know the truth--Samantha." They hug each other joyously. Come on, the carriage is waiting, says Quentin.

The Robservations references the quote perfectly...
And this is the second quote from this ep. The first (Judge Vail - 'You MUST refrain from any further demonstrations') was back on August 14th of 2020
