Fred Rogers alludes to his colorblindness in this episode, when he quietly comments to Mr. McFeely, "I don't see colors very well" as McFeely is showing him the same shirt in different colors.
Prince Tuesday: I like to be in school.
Harriet: And we like to have you, too, don't we, Daniel and Ana?
Daniel and Ana: I'll say.
Ana: That day when Prince Tuesday wasn't here, we were all sad.
Prince Tuesday: I like it here, better than home.
(Lady Elaine emerges)
Lady Elaine: Well, then you'd better come and live with me, Tuesday.
Prince Tuesday: Auntie Lady Elaine, you scared us.
Lady Elaine: I just think you'd better come and live with me at the Museum-Go-Round.
Prince Tuesday: Why?
Lady Elaine: Well, you know yourself. Things are awfully upset at your place. I mean, if your mom and dad get a divorce, you can come to live--
Harriet: Now, now, Lady Elaine, how could you say such a thing?
Lady Elaine: Well, it's the truth, isn't it?
Harriet: Nobody has said that the King and Queen are getting a divorce, have they?
Prince Tuesday: If they do, it'll be all my fault.
Harriet: I think we've talked about this enough. We just have to ask the King and Queen.
Prince Tuesday: I'm afraid to.
Harriet: Well, I'm your teacher, dear, so I can help you.
Prince Tuesday: You mean right now?
Harriet: Right now.
Ana: May we go along?
Harriet: I know you're worried about it, too, dear.
Daniel: And so am I, Miss Cow.
Harriet: Well, then we should all go. People shouldn't have to guess about important things.
Lady Elaine: I'm for that.
Harriet: Now, remember, Lady Elaine. The King and Queen and Prince Tuesday are Prince Tuesday's mother and father.
Ana: And they always will be, no matter what.
Prince Tuesday: They will?
Ana: Sure. If they get a divorce, or if they don't get a divorce, they'll still be your mom and dad. Nothing changes that.
Prince Tuesday: Oh, I didn't know that.
