The high-school principal has a strict rule about only parents visiting the school; Eric informing her about a family that wants an exception leads to the school board investigating the principal.

Simon calls Lucy and Kevin to borrow money. They turn to Eric for advice. Simon has been told to leave the dorm after breaking rules by having his girlfriend spend the night in his room.

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. .. _
