Annie continues to suffer through her mother's recent diagnosis. Annie then decides to go to Arizona to visit her parents and see what is going on with them. Meanwhile, Eric volunteers for a charity work, but he's unable to do it at the last minute. Matt then volunteers to do it, but his dating habits get him into trouble with the organization he is doing charity for. Also, Mary decides to call it a quits with Jeff while Lucy has her first real date with her classmate Jimmy Moon. Lastly, when Annie returns home with her parents, they decide to stay with her and the rest of the family so that they could spend some more time with them--which unfortunately will be the last for Annie's mom, Jenny.

The Camden kids think that their dad is having an extramarital affair when they catch him escorting a woman to a hotel alone. Annie struggles to give Eric the benefit of the doubt about his confidential church business even as all of Glen Oak buzzes with this gossip. Meanwhile, Simon endures his classmates' wrath when they discover his secret crush; he tries to con his way of out of going to school, but learns from his family that embarrassment will be drawn away from him and onto someone else soon. Matt tries to keep things moving slowly between Mary and her new boyfriend.

Simon rightly fears he'll catch roommate Ruthie's chicken-pox, but his enterprising hygienic measures fail to prevent contagion from her, or from Happy's fleas. When a robber carjacks them, Annie seems calm and hands their valuables, so Matt feels 'unmanly' and guilty. However, Anne breaks down at an identification lineup. Jimmy Moon stands against Lucy in the school elections, then turns to her parents for help. The church organist veers bizarrely from brilliance to disharmony.

Simon is eager to resume the baseball season, but not to get the mandatory tetanus-shot, but also a master at scaring needle-phobic Matt who has to accompany him and could fake it. Jimmy Moon needs some tutoring, so Lucy gets Mary to do it, but son regrets it, fearing big sister is falling for her boy-friend. Eric wants the parish to hire fraud-convicted Ron Kramer, an organist to the choirmaster's taste. Lou Dalton's vestry considers that as imprudent as having no security system in church and recruits Annie to be treasurer and draft a budget before the matter is settled, even threatening to fire Eric.
