[spoiler]Tuesday's quote:
Ep #41 (1966) - Vicki - 'Of course, that MUST be it.'
From "#0041/0042: Robservations 06/15/01: Sam's Torment"
Liz laces her hands and said she'd hoped to hear from Carolyn. Vicki brightly reveals that Carolyn called her earlier and said she would be out and possibly not home for dinner. Liz wishes she could have spoken to her herself, but Vicki says Carolyn didn't want to disturb her, she just told Vicki to tell her mother that. Liz wonders (hopes) if Carolyn has a date with Joe. Vicki agrees that of course, that must be it. Vicki gushes over what a nice boy Joe seems to be, and Liz smiles and agrees. Liz speculates that Carolyn might be looking, instead, for a very clever man. Vicki assures Liz that if she's worried about Carolyn being serious about Burke Devlin, she's not; Carolyn hardly knows him. Perhaps that's what intrigues her, Liz frets, and explains that she's sure Carolyn had planned to meet Burke this afternoon, but Roger was fortunately able to stop her. Pronounces Vicki, "If Carolyn planned to meet him, I don't think anyone could stop her!"
The Robservations references the quote perfectly...
And this is the third quote from this ep. The first (Roger - 'Well, if you MUST know, I spent it. But I had fun with my money, Liz. I enjoyed it. Can you say the same?') was back on February 13th of 2022, and the second (Roger - 'Well, if you MUST know, I had a perfectly valid reason for being home-- I prevented your daughter from meeting Burke Devlin'), which is from the same scene, was back on January 1st (
). And it would certainly appear that "Well, if you MUST know" was Roger's favorite phrase in the ep!
