Plot summary
Easy Walsh, who is split between Jenny Humphrey and Callie Vernon, decides to go after Callie. In front of the entire school, Jenny and Callie resolve to prioritise their friendship over their relationship with Easy.

After splitting with Jeremiah, Brett Messerschmidt is still hurt, and she subsequently develops an unexpected friendship with Kara Whalen. Brett had to bribe Heath with explicit photos of her and Kara in order to keep their relationship secret after confiding in the seasoned gossip Heath Ferro. The three consequently grow close.

Julian McCafferty, a freshman, hooks up with Tinsley Carmichael. But Tinsley notices that Julian is becoming more and more aloof, and she finds it hard to believe he could be getting tired of her.

After letting go of his affections for Callie and Jennie, Brandon Buchanan develops feelings for Elizabeth, a distinct and vivacious student at Jeremiah's school. To Brandon's dismay, Elizabeth wants to be free to visit other people and is terrified of becoming committed. When Brandon observes Elizabeth making out with another man at a party that Tinsley is throwing, he concludes that he cannot be in a committed relationship with her.

Easy proclaims his love for Callie, and they sleep together in a barn while the party rages on. Jenny walks in on them and runs out of the barn before they see her, later finding Julian behind it. They talk and realize their feelings for each other, finally kissing. A fire, started in the barn by Tinsley throwing Julian's lighter away, interrupts the two. In the aftermath of the party, rumors regarding the start of the fire abound. When Jenny confronts Callie about what she saw, they both accuse each other of starting the fire.

Brett and Kara's secret relationship is exposed when an intoxicated Callie lets the secret slip at the party, Kara having told Callie after a meeting of Women of Waverly. Angered, Brett seeks revenge.

Dean Marymount finds out about the fire in the barn and plans to expel whoever was responsible. Tinsley and Callie seize this moment as chance to frame Jenny.
