The episode opens with Lorelai and Rory having Friday Night Dinner with Emily; Richard is on a business trip to Germany. It is actually the evening of the same Friday that Rory missed the Shakespeare test in the previous episode, The Deer Hunters.
Later episodes will show Emily having a direct hotline to Chilton gossip through her friendship with Bitty Charleston, the headmaster’s wife. Yet Emily never brings up the fact that both Rory and Lorelai have thrown massive fits in the headmaster’s office that very day, and Rory was even sent home from school because of her behaviour.
Maybe her friendship with Bitty is not yet as close as it will be later, or Headmaster Charleston was unusually discreet about being yelled at by two Gilmores. For whatever reason, Lorelai seems to get away with it completely, and she has a rare escape from being chastised severely by her mother.
