Where We Left Off: The midseason finale saw Stan becoming a “cynical a**hole” on his 10th birthday -- he started growing apart from his friends as his view of the world began to change, leading to an unnerving friendship between Cartman and Kyle. Stan’s parents, Randy and Sharon, decided to separate and sell their house, with Sharon, Stan and Shelley moving into a new place at the episode’s end.

What's Next: Your guess is as good as ours, since Trey Parker and Matt Stone recently admitted they have no idea what the new episodes will be about in an interview with Jon Stewart.

Season 15 resumes Wed., Oct. 5, 10PM ET on Comedy Central
