Main Plot of the Season Premiere

The main plot of the season premiere (901/902) entitled “Just Can’t Get Enough” Part 1 and 2, will “feature” Peter and Mia according to Stephen Stohn on Twitter. You will remember that last year Mia was the focus of the season premiere as well. Nina Dobrev is leaving Degrassi eventually for her new show on the CW, the “Vampire Diaries.” It seems likely that her last episode is early in the season, because they have already shot it according to this eTalk clip, but we’re not sure if this season premiere is actually her last episode. Furthermore, does “feature” mean that they are the main focus of the episode? Or does it just mean that they are going to be in the episode?
