Ruthie's friend Peter is upset that his mother is marrying a man he does not know that well. Eric counsels him and the mother. Meanwhile Chandler helps another couple who wants to marry but has several problems with their relationship.

Annie's father has died, but Annie seems upbeat. Perhaps she is in the denial stage of grief. Chandler is still upset over losing his own father, and breaking up with Roxanne. Eric suggests he adopt a child.

Eric hides Mary's divorce from Annie, and Simon's romance heats up. While the Smiths brace for a custody battle over the Davis kids, Simon arrives home for an overnight visit with his girlfriend Rose (Sarah Thompson), whom Annie finds "condescending and rude." Annie's intuition tells her Rose is pushing Simon for marriage, and that something's up with Mary and Carlos. Although Eric knows Mary has filed for divorce, he avoids sharing that information with Annie just yet. Since Vincent doesn't have the guts to break up with Ruthie, Martin takes it upon himself to reveal the truth. Lucy is surprised by Annie's erroneous assumption that Carlos and Mary are still together. Meanwhile, Simon hears from Kevin that Rose had led Annie to believe they're engaged. When Simon confronts Rose, he reiterates that, even if they discussed the possibility of marriage, he didn't actually propose. Visibly upset, Rose walks off. The Davis kids are stunned to learn their mom is refusing to relinquish custody. As much as they want to be adopted by the Smiths, the children fear that if they testify against their mother in family court, she'll wind up turning to drugs and alcohol. That's not a risk they're willing to take. Later, Ruthie asks Vincent to never call her again, and Rose asks Simon what he wants from their relationship. To Kevin's delight, Lucy puts an offer on a fixer-upper house next door! The Smiths and Davises reach a compromise: George and his wife won't push for adoption, but Mrs. Davis will allow them to become the kids' foster parents. Minutes after Eric shocks Annie with the news of Mary's divorce, Simon and Rose announce they intend to get engaged "in the near future." That evening, the Camdens join Martin as he welcomes his father home from Iraq. .. _
