Details of Tuesday's Glee Season 3, Episode 14: “On My Way” midseason finale are being kept so tightly under wraps... not even the sneak peek is willing to give too much away! We know it's Regionals. We know Sebastian (Grant Gustin) will be back. But what are these "Big plot twists?" How is the episode going to be "An emotional rollercoaster?" And if we're going to be in tears the entire episode... and clues as to why? We're getting a bit nervous!
