[spoiler]Saturday's quote:
Ep #646 (1968) - David - 'My family has made the two of us very unhappy. They MUST be made to realize that. They MUST pay for what they've done to us.'
From "Robservations 9/13/02 #645/646 - The Kids "Play" With Roger"
The kids have slipped into the clothing that was in the trunk. Amy tells David he looks grown-up, and he asks, "Like Quentin?" Yes, she says. He asks her to call him Quentin, and she says to call her Beth. They can pretend this is their room. It is, says David, don't you remember --Beth? Yes, Quentin, she responds. We must keep it a secret, warns David, if we tell, and the adults came up there, they wouldn't let them play our games--we'll block the entrance to the room so no one will find it. Amy suggests they go downstairs, it's getting late and they must rise early. David agrees--they have much to do. Amy agrees. He asks what's wrong. I wonder if we will do what HE wants.We must, says David--my family has made Quentin and Beth very unhappy and must be made to realize that--must pay for what they've done to them! I understand, says Amy. David touches her shoulder and asks if she's thinking of letting him do this all alone. Of course not, she assures him.

Another double "MUST" quote. And the Robservations basically features it word for word with the exception of changing "the two of us" to "Quentin and Beth" (Robin probably felt the way it's actually phrased might be confusing) and changing "they've done to us" to "they've done to them" (for the same reason). The Robservations also drops the pronoun "they" in "They must be made" and "They must pay" - but those are minor things.
