When Jeff (Joel McHale) announces his plan to graduate early, Abed (Danny Pudi) retreats to his “happy place”—a cheesy sitcom version of Greendale where the study group must start over as freshmen. Meanwhile, Troy (Donald Glover) fights with Britta (Gillian Jacobs) over a first-day-of-school tradition and Annie (Alison Brie) worries that she is the only one of her friends who hasn’t changed for the better.
On the way to a Halloween party, the study group must free Pierce (Chevy Chase) from his panic room and slowly comes to suspect that his mansion is being haunted by the ghost of his late father. Guest starring Giancarlo Esposito.
Troy (Donald Glover) worries about losing Abed (Danny Pudi) to a fellow obsessive Inspector Spacetime fan at a convention for the show, while Annie (Alison Brie) fantasizes about being married to Jeff (Joel McHale) after he backs out of their weekend plans. Guest starring Matt Lucas, Tricia Helfer, and Jerry O’Connell.
After losing out in registration for “The History of Ice Cream,” the study group begins their European History class with Professor Noel Cornwallis (Malcolm McDowell, “Entourage,” “Franklin and Bash”). To make matters worse, the group encounters the return of the arrogant German students from last season, which Jeff (Joel McHale) and Shirley (Yvette Nicole Brown) faced over the foosball table. Meanwhile, much to Dean Pelton’s (Jim Rash) dismay, Chang (Ken Jeong) returns to campus with a bad case of “Changnesia,” appearing not to remember anything of last year’s Armageddon.
As Britta (Gillian Jacobs) follows Jeff (Joel McHale) home to see his estranged father (guest star James Brolin) on Thanksgiving, Shirley (Yvette Nicole Brown) invites the rest of the study group to spend the holiday with her judgmental in-laws.
Dean Pelton asks the study group to help secure a grant for research into Chang's memory loss, while Abed films their efforts for a documentary.
