Sorry for bumping this, but I'm a huuugeee Gleek (Lea Michele's fault, damn that woman for being so flawless!) and last Friday's episode was called "Transitioning". Coach Beiste is back after coming out as a transgender man, his new name is Sheldon.
It was a sweet episode, Alex Newell's character, Unique, was back and sang with a group of 300 transgender people to Sheldon, so that he'd know he's not alone. Also, it felt very nice to see the main characters supporting the coach, so yeah... even if you've given up on Glee (cause, let's face it, the quality has gone down a lot in the past few years...), you might wanna check this episode out, it was pretty cool.
