Professor Macklin decides that abstinence will be the topic of the week. Owen and Natalie begin to rethink their relationship after she will not allow him to stay with her for a few days. This makes Natalie think about giving Richard a second chance. Lee, however, is having problems abstaining from gambling and sex and must take a loan from Richard to pay his gambling debt. Richard decides to hire Zoe to be the school newspaper’s new sex columnist, and Sarah almost gives her former professor/lover another chance, until she discovers that she's not the only student he has eyes for.
