The holiday-themed episode will have New Directions facing a tough decision when they're asked to perform at two different events on the same day. Meanwhile, the show will also host a very special guest.
"[Chewbacca] makes an appearance into Artie's dream in a way," Harry Shum, Jr. tells AOL TV. "I can't really delve into the details, but it's something to do with Artie." Did you hear that, 'Star Wars' Gleeks?
