[spoiler]Tuesday's quote:
Ep #196 (1967) - Liz - 'You MUST be careful, particularly now, not to misinterpret what you see or hear.'
From "#0196/0197: Robervations 10/09/01: Blackmailed by a Blackguard"
"I will not be cross-examined or have my motives analyzed!" says Liz, leaping to her feet. "I invited a houseguest and that is it." Vicki begs her not to allow herself to get too excited. (Vicki, Roger and Carolyn are lined up in front of the fireplace, leaving Liz standing alone by the sofa. It underlines how isolated she must feel right now.) Roger walks over to her, assuring her they aren't attacking her. They're obviously interested and concerned about her friend, that's all. "He isn't your concern," says Liz crisply, "so you hereby have my permission to ignore him." Actually, he seemed a pleasant enough sort, says Roger sarcastically, but if that's your attitude, I might take your advice--and he leaves the room. Carolyn apologizes to her mother for causing this. Not your fault, says Liz. I've been reading meanings into things that don't exist, says Carolyn. Liz tells her to be careful, especially now, and not misinterpret what she sees and hears. I'll try, Carolyn promises, and I'm not like Uncle Roger--I'll make Jason feel welcome. No, that isn't necessary, says Liz, too sharply, then adds, more softly, I don't want you to go out of your way. Don't worry, says Carolyn, it's no trouble at all! And she leaves, too. Vicki is the only one left. She walks over to Liz and asks if there's anything she can do. No, says Liz. You should get some rest, advises Vicki. I'm beginning to feel tired, says Liz. You need to get your strength back, says Vicki. Liz agrees she's going to need all the strength she can muster. Why do you say that? asks Vicki. Liz tells her she's going to need her support. You know you have it, says the young woman.

The Robservations references the quote well even though it doesn't use "must" and it uses "especially" instead of "particularly"...
And this is the second quote from this ep. The first (Liz - 'MUST you indict everyone?') was back on July 14 of 2020.
