Stephanie laughing along with the other kids
Stephanie being teased by another student
Stephanie's classmate Jamie, who plays guitar with some friends in a band called Human Pudding, asks Steph to go on a date with him to The Smash Club, and Stephanie excitedly agrees. Stephanie's rival, Gia Mahan, is not exactly as excited about it as Stephanie is. It turns out that Gia likes Jamie too, and she is not about to let Stephanie have him that easily. Gia comes over to the house and warns Stephanie to break the date, or she will make her life miserable. However, Steph stands her ground, and refuses to break the date. Little does Stephanie know how dirty Gia is willing to play to get him.
The next day at school, in order to make Jamie cancel his date with Stephanie, Gia spreads around a false rumor that Stephanie wouldn't get any dates with guys unless she paid them to date her, and even put a sign with the words "Date Stephanie, earn big bucks" on Stephanie's locker. Jamie, who has been getting ragged on because of the rumor, asks Stephanie who started it, and she says, "Gia. She said if we didn't call off our date, she'd make my life miserable." Jamie thinks that maybe it is a good idea to break the date, because he does not want to get ragged on anymore. Stephanie is hurt by that.
The next day, with the help of her friend Mickey, Stephanie gets even with Gia by hanging up a blow-up of Gia's failing report card in the hallway. Jamie apologizes to Stephanie for the events of the previous day, and tells her that he is not about to let Gia run his life. Jamie says that if it is okay with Stephanie, the date can be back on, and she likes that. Stephanie shows him what she did to Gia, and Jamie says that she had it coming. Gia comes in and sees what happened, and, after angrily yanking the blow-up off the wall, goes straight to her locker. Stephanie walks up to Gia, who has her face buried in her locker, and says, "So, Gia, I guess we're even". Gia turns around, and Stephanie sees the tears on her face. Stephanie then feels guilty. At The Smash Club that night, after a talk with Jesse about the situation, Stephanie sees Gia. Stephanie and Gia talk, and they finally become friends (while also realizing that revenge isn't exactly as sweet as it's made out to be).
