Glee club co-captain Rachel Berry (Lea Michele) tries to take over for Will. This results in problems. At the request of Kurt Hummel (Chris Colfer), club lessons are taught by substitute teacher Holly Holliday (Gwyneth Paltrow). She has different ways of doing things. These include talking about Lindsay Lohan's rehabilitation in Spanish, singing "Conjunction Junction" to her English class, and pretending to be a bipolar Mary Todd Lincoln for the History class. When Holly first goes to glee club rehearsal, she does a cover of Cee Lo Green's "Forget You". The group likes her performance. Rachel is annoyed. She is worried that Holly may not be able to get them ready for the Sectionals competition. Holly later wins over Rachel by "duetting" with her on "Nowadays/Hot Honey Rag" from the musical "Chicago".
