Family

Buddy hears Kate say something about her, and isn't happy. Also, Nancy walks in on Jeff with another woman.

Buddy gets a job at a bakery, and introduces Willie to her boss, ""Big Al""; Nancy gets involved with Peter, while she's finalizing her divorce from Jeff -- despite the latter's pleas for a reconciliation.

While Nancy and Buddy prepare for their parents' 25th wedding-anniversary party, Willie meets, and falls in love with, a physics student named Lizzy -- who, as he soon finds out, has radiation sickness.

Annie's sole surviving relative dumps her into the Lawrences' lap -- where she doesn't feel quite comfortable, at first.

Doug's father starts showing his age.
