"Are You Afraid of the Dark" seems to have a love affair with a few storylines, one of them being "an attractive young woman runs afoul of a crafty wench who steals her beauty." The beauty and the beauty-thief are always female, since, y'know, women are all vain and stuff. What could be more horrifying to them than losing what matters most?
Anyway, the story involves Catherine, an average girl who wants to be extraordinary. She gets her wish when she stumbles upon a little-bazaar-that-wasn't-there-yesterday, run by Marie, a woman whose odd mannerisms and half-hidden face should tell you that something's up. But Catherine is an especially slow protagonist in the vein of the boy from "The Tale of the Bookish Babysitter," so she makes ambiguous trades for Tennis Shoes of Superspeed, Ugly Green Shirt of Hunk Attraction, and some concert tickets, which may or may not be magical. Even after seeing Marie's hideous boil-covered visage, Catherine continues using her wares. It's wall-bangingly frustrating how dim this girl is.
I won't spoil the ending (it's a huge deus ex machina anyway), but you know by now that we eventually get to see a boil-covered Catherine realize just what she was trading all those times. It's -- like most AYAOTD episodes -- campy fun, and it doesn't disappoint.
[On Catherine's idiosyncratic fashion sense] "I guess the Roaring Twenties gangster look was all the rage in 90's Canada."
[After Catherine's bazaar-bought shoes make her a track star but an all-around jerk] "Increased athletic performance and mood swings? She's totally on 'roids."
