Cindy and Carol are supposed to check into the hospital at 6:00 p.m on Saturday. While packing, Carol reminds Peter that he has a dental appointment in the morning (Sunday).
The Dr. said for them to be there Friday before 6:00pm. Dentists do have Saturday appointments.
Mike Lookinland (Bobby) does not appear in this episode. While Bobby is mentioned a few times, he is suspiciously absent as the entire family returns home from a boat trip, with no explanation at all about why he is not there.
Cindy is sneezing often. The doctor checks her tonsils despite sneezing not being a symptom of tonsillitis.
