Mezz warns Nick not to meddle in other people's personal lives; but when Nick teases Elana about her boring, predictable relationship with her fiancé, Roger, Elana believes Nick's comments and ends her marriage engagement. Nick tries to reunite the couple by getting them both to come to a school dance. But Elana realizes how much fun life is without Roger, and she rebuffs him. Elana tells Roger that she actually loves Nick. Nick, who is infatuated with Elana, joyfully declares his feelings for her. But later, Nick is disappointed when Elana tells him that she was pretending because Roger was present; she doesn't love Nick. Nick acts as if he were lying too. He realizes Mezz was right. Meanwhile, it's the first dance for Nick's students, and he must struggle to relieve their anxiety. Sarah and Orlando are the only ones who don't go as a ""couple"" -- and the only ones who end up enjoying themselves.
