A Dalton Academy Warbler, the character played by Grant Gustin will come between Kurt and Blaine.
A look at new "Glee" character, Sebastian, has been unveiled in a photo which makes its way out via TVLine. Donning Dalton Academy's uniform, the Warblers member who is portrayed by Grant Gustin will bring a new love triangle on the musical show.
It has been reported that Sebastian will set his sights on Blaine and bring a big trouble for Kurt. "He's our villain this season," so an insider called the new gay Warbler. He was also said as the polar opposite of Kurt in every possible way, with the adjectives "promiscuous" and "scheming" being used to describe him.
Sebastian will first appear in the fifth episode of season 3 which is titled "The First Time". Ironically, the November 8 outing will also mark the first time Kurt and Blaine consummate their relationship.
