Simon doesn't enjoy bully-mate Rick's girl abusing him as excuse to dump him. Annie experiences her flippant advice nearly wrecked pupil Christy Parks's parents' marriage, yet resists help even from Eric.

The Camden house gets a little more crowded when Mary returns, and tells her family that she is home to stay. Mary's sudden arrival has everyone in the family wondering what happened between her and Wilson. Are they married? Did they break up? Only Mary knows and she is not telling—at least not yet. Her presence delights Annie, who goes out of her way to make her daughter comfortable, even offering her the coveted garage apartment. But not everyone is happy to see her. Ruthie feels that Mary owes everyone an apology for the actions that led to her initial ouster from the Camden home.
