It's graduation day - and both Ricky and Jack have something to say. A divorce attorney obtains incriminating photos at the graduation ceremonies.

Amy and Ricky are now engaged, but Amy starts to consider what marriage may really mean.

Amy is increasingly short with everyone in her life, including Ricky, leaving him wondering what is going on with her, but he is not prepared when she reveals that she might be pregnant again. Ben, determined to get permission from Dylan's parents to see her, makes another attempt to win them over, but it doesn't turn out quite like he hoped when he ends up sharing too much information about his family. Grace is unsure how to react to her mother's shocking news about the secret her father kept from everyone and turns to Jack for support. And, Anne's evening with Nora raises questions for George.

Dylan and her pals surprise Ben at school, while Grace doesn't want Jacob attending school with her. Elsewhere, Kathleen tries to understand her late husband's secrets; and an overburdened Amy acts ornery at home with Ricky.

Amy announces a wedding date, and the news travels quickly. Meanwhile, a rumor concerning Anne surfaces.

Amy begins her senior year of high school and gives guidance to a new student, who's six months pregnant. Meanwhile, Ricky gets an opportunity to work for Leo full-time; Ben shares his feelings with Amy; Ricky and Amy watch a video of their wedding.
