Terri Schuester is a teacher on Glee. She's married to Will, the man at the center of the show that's trying to resurrect the school's glee club.
Terri is a strong, intense character. She loves her husband, no doubt, but she's definitely critical of his attempt to take over a group of singing nitwits.
Terri: I'm the new school nurse.
Will: But you don't have any training.
Terri: Please, Will, it's a public school.
Will: We can't afford this.
Terri: All we need to do is give up Applebeer's and AC for the first few summers.
