Breanna and Spirit hold audition for a new cheerleader on their cheerleading squad. So far all the people who try out suck except for one girl who just recently moved to Baltimore and transferred to McKinley. Her name is Charlotte and not only does she make the squad but she and Breanna quickly become friends. While getting to know each other Charlotte tells Spirit and Breanna that even though she just moved to Baltimore she was still here over the summer visiting her grandmother. Charlotte also mentions that during the summer she met a guy and had sex with him. Breanna and Spirit get really curious and ask her who and she says Arnaz! When Breanna discovers that she's the girl that Arnaz lost her virginity too this makes Breanna mad putting a dent in her new friendship with Charlotte. The next few days Breanna starts to treat her really cruelly, but Spirit knocks some sense into Breanna by saying that she should really be mad at Arnaz. During the annual school cheer-off Breanna and Charlotte make up. She also tells Breanna that even though she had sex with Arnaz, Arnaz had told her that there was already a special girl in his life who he had given a special half-heart locket which is Breanna. Meanwhile Flex and Duane go up against each other for the condo board presidency.
