Alex Newell, who finished as a runner up on the Oxygen reality show The Glee Project, guest starred Tuesday on 'Glee' as Unique, the show's first transgender character.

On the episode, Wade, a member of rival glee club Vocal Adrenaline, confides in gay student Kurt (played by Chris Colfer) and Mercedes (Amber Riley).

“Ever since I was a kid, I would play this game,” Wade says. “Where I would pretend I was a different person. The person I dreamed of being. The real me. I even have a different name. Unique.”

“I hope one day you have enough courage to be him,” Kurt says

“Actually, Unique's a her,” Wade answers.

Later, fearing for Wade's safety, Kurt and Mercedes attempt to dissuade Wade from performing as Unique.

“I've worn some flamboyant outfits, but I've never dressed up as a woman,” Kurt says.

“That's because you identify yourself as a man. I thought you of all people would understand,” Unique responds. (Watch Unique performing Boggie Shoes in the video embedded in the right panel of this page. Visit our video library for more videos.)

On the possibility of playing a transgender character, Newell told The Hollywood Reporter: “Not too many television shows shed light on that, it's that hidden thing that not everybody wants to talk about. But it is there and there are people that want to be able to turn the television on and see somebody else who is just like them. I feel like if I were able to that, I'd be beside myself and happy.”
