Ritchie goes to church with Richard and new Christine without consulting his mother first, leaving old Christine to explain and explore her aversion to organized religion.

Christine's attraction to Ritchie's teacher causes a scene at a school fund-raiser--especially after she wins a playdate with the man.

On their way to Ritchie's desert camping trip, Christine, Richard, Matthew, and Barb stay at a seedy motel and get on each others' nerves.

Roles reverse when Christine's dubbed a "meanie mom" by a father at Ritchie's school who finds Marly and Lindsay to be to his liking.

Christine tries to forbid Barb and Matthew from letting a night of passion bloom into a full-blown relationship.
