In Watch Out Now, as the students walk into the school, it is revealed that Simpson is gone and that Ms. Pill is the new principal. She enforces many new policies such as confiscation of cellphones during school hours and the ban of public displays of affection. She also requires that all school clubs be approved by her.
In Wishlist, she witnesses Imogen Moreno kneeing Damon Carter in the groin and calls her down to her office. After Imogen explains that she and Jack Jones were being harassed by him, she tries to validate the story with Jack, who lies and says Imogen is overreacting to avoid her parents finding out about the situation and her sexuality. Ms. Pill then drops the subject since Jack sees it as no big deal which upsets Imogen profusely.
