Kaylie is with Lizzie and Sam at the dive bar, where they see a guy who looks like Jordan pick up a busty Blonde. Kaylie is devastated. Lizzie and Sam tell her that all men cheat, and offer examples from their pasts. They urge her to even the score by making him jealous. Lizzie and Sam stalk Jordan, trying to catch him cheating. They follow him to the gym and to breakfast; that night, they watch as someone who looks like him enters his apartment building with the Blonde in tow. Sam uses a ruse to get them into Brad's apartment so they can spy from across the alley. Sam stays behind, has sex with Brad, and dumps him like he did her. Lizzie and Sam present their inconclusive evidence to Kaylie, and tell her it's time to make Jordan cry. Kaylie has Tyrone escort her to the dive bar. Jordan walks in, sees them together, and is heartbroken. When presented with the "evidence," he tells them that he moved that weekend and spent it unpacking -- he isn't the guy on the video. Kaylie and Jordan make up and leave together; Tyrone joins the busty Blonde; Jason tells Lizzie and Sam that their rules don't work, which is why they are alone. Sam goes home and listens to Kaylie and Jordan having sex on the other side of the wall.
