Laura: It was your powders. It was your powders that made Jack well again! You can't leave now. If you stay, you won't ever have any sick people or
animals in Walnut Grove. We won't even need a doctor! Someone's feeling just a little bit sick, and all they have to do is go to you, and you can give them
one of your secret powders, and they'll be all well again. Promise. Say that
you will!
Mr. O'Hara: (long pause) No, child. I didn't make Jack well.
Laura: You're teasing.
Mr. O'Hara: No, Laura. Your father said that what I mostly did was tricks, now didn't he?
Laura: All tricks, he said.
Mr. O'Hara: Nothing about me is real. Nothing. Not even my name, or the way I talk. All circus tricks.
Laura: Not the powders?
Mr. O'Hara: Especially the powders. Sugar and soda, and a bit of fizz. And that's all they are.
Laura: Why, Mr. O'Hara? Why do you fool people like that?
Mr. O'Hara: All the roads were lonely. I guess that's why I gave some
of them the magic powders, to make them feel beholden to me, to think that I
was......a little better, a little taller, and a little wiser than I really am.
