Glee‘s sixth and final season will jump ahead in time, and take place back in Lima, Ohio, as Rachel (Lea Michele) returns to McKinley High to try to salvage New Directions, after her own Hollywood/Broadway career failed.
Original plans by co-creator Ryan Murphy, prior to the death of Cory Monteith, were to feature a happy ending for Rachel and Finn.
“The fact that that can’t be is a big pain in all of our hearts,” he has said.
