In this episode we meet Michel’s mother, Giselle, who is visiting from Paris. She and Michel adore each other, and are “best friends” mother and son, who love to tease and joke with each other, using a banter that sounds like something out of a Noel Coward play.
This makes them seem quite similar to Lorelai and Rory, who are also self-proclaimed “best friends” with a comic patter between them. Janet Hubert is only fourteen years older than Yanic Truesale, suggesting she is supposed to be a very young glamorous mother like Lorelai.
Michel addresses his mother by her first name at one point, and you can hear the French pronunciation of it – ZEE-ZEHL. Giselle may have possibly been named with the French ballet Giselle in mind, one of the world’s most popular classical ballets.
