Glee club
Glee club director Will Schuester (Matthew Morrison) decides to have New Directions twerk in Nationals to "edge up" their performance, and recruits Jake Puckerman (Jacob Artist) and Kitty Wilde (Becca Tobin) to teach the dance to the rest of the group. Meanwhile, Wade "Unique" Adams is caught using the girls' bathroom by Bree (Erinn Westbrook), and is forced to use the boys' bathroom from then on.
