I’ve never seen that episode but it reminded me of the Dictionopolis Word Market in The Phantom Tollbooth:
“Step right up, step right up—fancy, best-quality words right here,” announced one man in a booming voice. “Step right up—ah, what can I do for you, little boy? How about a nice bagful of pronouns—or maybe you’d like our special assortment of names?”
Milo had never thought much about words before, but these looked so good that he longed to have some…
@Sanglorian: I don’t really have any reason for the sister looking for Lust, except that I needed Iren to be alone (i.e. I needed a reason why her sister wouldn’t accompany her on the search for Sanity)… Is it too weird/confusing of a line?
