Glee Episode Promo: The Return of Shelby!

Glee returned last night, with new directions for various characters and a renewed focus on the graduating class. What did you think of "The Purple Piano Project?"

Looking ahead to next Tuesday, viewers should prepare themselves for the return of a familiar face: Idina Menzel reprises her role as Shelby Corcoran. What will her return mean for Rachel? Or, based on the following promo, for Quinn? And why the heck is the installment titled "I Am Unicorn?!?"

Elsewhere on the episode, look for Will to put his kids through a "boot camp."
