Simon is reluctant to talk to Eric and Annie about his relationship with Georgia (guest star Rheagan Wallace). However, he eventually drops the bomb that they are having sex and that he's currently on academic probation for skipping classes to be with her. Meanwhile, Simon's situation helps Eric realize that the church should teach teens the importance of abstinence and he asks Lucy to lead a class on the subject. Also, Lucy and Kevin learn the sex of their baby, and Lucy starts to question her ability to be a good mother. Matt is worried that Martin is still broken-hearted over Cecilia and will tell her about Simon's new relationship with Georgia. Lastly, Matt chips away at Ruthie's unwillingness to apologize to Martin.
