Darren Criss' out-and-proud Blaine Anderson on Glee will be taken a step further with Grant Gustin's upcoming Sebastian.

In the premiere episode of the show's third season, Blaine transferred out of the Dalton Academy to William McKinley High to be with his boyfriend Kurt Hummel (played by Chris Colfer). But their idyllic romance is headed toward turbulence as Sebastian, a gay Dalton Academy Warbler, enters the picture and sets his sights on Blaine.

Gustin, whose credits include playing Baby John in the national tour of West Side Story, said his character takes confidence to a new level.

“Sebastian is new to Dalton. He's a gay character, obviously, but he's kind of a new type of gay character. He's someone you wouldn't necessarily know is gay unless you asked him, but he'd be the first person to tell you. He's very confident and comfortable with who he is and what he wants. Darren (Criss) was that new confident strong gay character, and Sebastian is taking that a step further. He's a guys-guy, just a dude who happens to be gay. He's a lacrosse player, he's popular. He's after Blaine, obviously, and he's also trying to take the place that Blaine had as the leader of the Warblers,” Gustin told music glossy Billboard.

“He's been referred to as a villain, which I guess is true in the sense that he's going to get what he wants and he doesn't care who he steps on along the way, but he does so with a smile on his face,” he added.

Sebastian arrives on the November 8 episode of Glee.
