A new character has just been cast as a Warbler for upcoming episodes of Glee! And he has a MAJOR role. [MAJOR SPOILERS AHEAD]

According to TVline.com, a new gay character will be joining the Dalton Academy Warblers!

Grant will play a character named Sebastian who is setting his sights on Blaine.

According to TVline.com’s sources, Sebastian will be the polar opposite of Kurt in every way.

He’s more like the male version of Santana in that he’s both promiscuous and kinda-sorta scheming.

The insider also says that he is definitely taking on a villainous role:

“He’s our villain this season,” an insider tells me. “It’s a major role.”

On Sunday we told you that Blaine would be heading back to Dalton. Could this be why??

Wow! We knew the Klaine romance wasn’t going to be a honeymoon forever!

What are your thoughts about this Sebastian character?

Thanks to Natalie for the tip!
