The conflict between Kathleen Mead and Tabi began when Tabi bullied Kathleen during her freshman year. The girls disliked each other, but were locker neighbors to their dismay. Tabi would always make sure Kathleen couldn't get her stuff by blocking her locker; and if she did obtain her books, she would be late to class. One day when Kathleen was already depressed she had enough of Tabi and shoved her into a locker. The girls ended up in a fight which Kathleen won.

The older girls then laugh as the freshman look hopeless.
Later in the hall, they see a student sign up for the school play and then tells Kathleen that she should as well; she does, and then tells Melanie about it, saying that the boy was definitely cute and definitely smiled at her.

Kathleen tells Melanie that they should just come back later, but Melanie points out that they need their books for class.

They get to their lockers; Tabi is there again with her friends, blocking the locker doors.
