It's Glee's Gaga approved history-making episode all about acceptance! Except Kevin and Jenna didn't really love this episode when they re-watched it… at first! What made them change their tune… Was it the return of Kurt? The scene where they didn’t have to act? Or Santana's one-liners? Plus, this super-sized episode features the number two most-listened to Glee song, and it's not "Born This Way."
