s07e05 The Great Stink

Emily (Kelly Bishop) and Richard (Edward Herrmann) are delighted when Lorelai (Lauren Graham) and Christopher (David Sutcliffe) attend Friday night dinner together as a couple. Christopher reveals that Sherry has written him a letter saying she regrets leaving their daughter, GiGi (guest star Nicolette Collier), and asking him to send GiGi to visit her in Paris. Lorelai can't believe that Chris would consider this and they get into an argument over dinner. Logan (Matt Czuchry) returns to town on business to acquire an internet company and pays Rory (Alexis Bledel) a surprise visit. Rory is thrilled, but during a dinner with Logan's colleagues, she realizes that she has no connection to his new business world, and is especially threatened by one of his beautiful co-workers. Meanwhile, Stars Hollow is plagued by a terrible odor when a train with a full load of pickles derails, and Taylor (Michael Winters) refuses to pay for the cleanup.
