Darren Criss has been cast as a gay student who may or may not romance Kurt in season 2.
The actor who would possibly be Kurt's first boyfriend on "Glee" has been cast. Darren Criss, the star of "Eastwick", has scored a place on the musical series as a charismatic gay student from a rival Glee club called the Dalton Academy Warblers. Although his orientation has been made clear, the chance that he's Kurt's love interest is still blurry.
Creator Ryan Murphy said before that Kurt will get a boyfriend in season 2 and they would be a power couple. Many thought Chord Overstreet's character Sam would be the one but Chris Colfer denied this, saying there's no chemistry between Kurt and Sam in the first few episodes. The speculation has since been moved to Criss' Blaine.
But according to EW's source, Blaine will "maintain a strictly platonic friendship with McKinley High's most out and proud pupil." However, there is still room for it to change in the future, otherwise the show would have to cast another actor.
