Some new information has surfaced about the 4 parter episode at the end of season 9. I think we can all assume that it will be aired as a movie.
Stephen Stohn on Twitter tells us that the episodes are called “The Rest of my Life” parts 1-4 (remember Degrassi Goes Hollywood was originally “Paradise City” parts 1-4). Like Paradise City, these episodes will be shot out of order and will be directed by Stefan Brogren. No word yet on the characters or concept behind this latest Degrassi movie.
