Tread Perilously's Halloween month crosses the border into Canada for a special internet-only episode of Degrassi: The Next Generation, "The Curse of Degrassi."

When the ghost of Rick Murray awakens before the Harvest Dance, he possesses Holly J to get his revenge on Spinner and some of the other kids. Will it bring Mia and Jane closer together after drifting apart? Will it prevent other teens from making out in a supply closet? And will it allow Spinner to realize he's an actor in a non-continuity Halloween special of a Canadian teen drama?

Erik and Justin brace themselves for the 2000s nostalgia wave, even as they still have problems with a lot of turn-of-the-century styles. Erik reveals his dislike of fashions from Georgian period England. Justin reveals the episode writer/director's connection to Degrassi Junior High. The pair discuss the premise of nearly all Degrassi shows. Justin also goes on a Friday Night Lights tear thanks to the slightest provocation. Erik also tries to figure out how the special was produced for a website. He also attempts a Nina Dobrev impression. Justin provides a more accurate account of what happened to Rick and a new contender to play Doom enters the arena.
