[spoiler]Sunday's quote:
Ep #64 (1966) - Liz - 'I suppose you should, if you feel you MUST.'
From "#0063/0064: Robservations 07/02/01: Who Isn't Capable of Murder?"
I've only been concerned about what's best for you, Liz tells Carolyn, how I wish you could have gone away from here before all this started. It wouldn't have changed anything, insists Carolyn. For you it would have, says Liz--I know what you've been going through. Mother, says Carolyn, I've always liked Burke. Always? asks Liz, you've known him such a short time. I know, but...why did he have to do it? asks Carolyn--why did he have to say those horrible things about Uncle Roger? Because he's bitter and angry, says Liz. He always seems so...I don't know, so different, says Carolyn--how can you ever know anything about anybody? I've never learned the answer to that question, says Liz, smiling, I suppose you have to put faith in someone you love and hope they'll be honest with you. Yes, agrees Carolyn, if I could only talk to Burke and asks him how he could say these things. I suppose you should, if you feel you must, says Liz You wouldn't object? asks Carolyn. Would it make any difference if I did? asks Liz. No, I suppose not, says Carolyn.
