It's the Glee episode we should have seen last year! At least, that's the premise of Glee's Season 5, Episode 8: "Previously Unaired Christmas." In the episode, we'll see Rachel (Lea Michele), Kurt (Chris Colfer), and Naya Rivera (Santana) working as sexy mall elves, while McKinley's kids are choosing roles for the Nativity scene.
