[spoiler]Monday's quote:
Ep #159 (1967) - Vicki - 'But you MUST understand.'
From "#0158/0159: Robservations 09/11/01: Liz Loses All Her Marbles"
I didn't realize that I was keeping David from his studies, says Laura. I didn't mean to blame you, it's not your fault, says Vicki, but you must understand, with Mrs. Stoddard so sick, we have to try and keep things running as smoothly as possible. I agree with you completely, says Laura, you're a very bright, loyal girl. Thank you, says Vicki. Did you notice how I backed you up about David's studies? Yes, says Vicki. And how willing I was to make adjustments? says Laura. Yes, you saved me from quite a scrap with him, agrees Vicki. I'm very glad about that, says Laura--however, I am a little disappointed in you, Vicki. Why? asks Vicki. Because you were so helpful to me in that very difficult beginning with David, says Laura--but right now you're not backing me up--I wonder why? Vicki turns away, uncomfortable.

This Robservations references the quote perfectly...
And given how often over the course of the show Vicki says she doesn't understand, isn't it ironic to see Vicki telling someone else they must understand?
Though at this point on the show, and especially during this storyline, Vicki does understand quite a lot and figures out things before anyone else. If only they continued writing her that way. Chances are Alexandra wouldn't have become quite as dissatisfied playing Vicki as she eventually would. But once Art Wallace left...
And this is the third quote from this ep. The first (Vicki - 'You MUST remember that she hasn't been out of here for 18 years. Something's keeping her here') was back on November 2nd, and the second (Laura - 'David, we MUST never let anyone come between us') was back on November 14th.
