Glee Season 1 Episode 6 : Vitamin D
Believing the glee club members are becoming complacent ahead of Sectionals, Will pits the girls against the boys for a mash-up competition. Terri takes a job as the school nurse to stop Will becoming closer to Emma. With encouragement from Terri, Ken proposes to Emma, who reluctantly accepts. Terri gives the glee club pseudoephedrine tablets, enhancing their mash-up performances. Rachel and Finn feel guilty and confess, resulting in the competition being nullified, Terri being fired, and Sue being appointed co-director of the glee club. Quinn agrees to let Terri secretly adopt her baby, enabling her to continue faking her pregnancy.
