Back by Popular Demand

Back by Popular Demand is the fifteenth episode of the first season of the fanfiction series, Glee: Los Angeles, and the fifteenth overall. It was written by REBƎLReloaded, former writer of Glee: The New Years and Glee: Make it or Break It.

Karen returns back to West Ridge High after a previous suspension from her duties, but she decides to make peace with Mercedes on one condition - to help get her career back on track. A new drama teacher, Noel Seeley (portrayed by Michael Angarano) may jeopardize Mercedes's job at West Ridge High, as he coerces members of Harmonic Explosion to join his drama club. Caleb makes Charlotte feel replaced by his dreams of Broadway, while Adriana and Scott are unable to come to terms with actively communicating.
