Criss was introduced in Tuesday's episode as Blaine, a gay student at a local all-boys academy. He befriends Kurt (Chris Colfer) and helps him deal with bullying at McKinley High. Blaine is also a member of the Dalton Academy's glee club, the Warblers, one of the teams Kurt's New Directions must face in sectionals.

So what does this possible promotion mean for Kurt's new source of courage? Will Blaine become more than a friend to Kurt? Is Kurt switching to Dalton Academy, or is Blaine headed for New Directions at McKinley High?

Criss is also known for his work on the short-lived series Eastwick and the YouTube Harry Potter send-up, A Very Potter Musical.
