LUKE: What the hell was that?
LORELAI: That was episode one of Rory and Jess: The Early Years.
Compare to Lorelai saying a potential situation with her father was like Who’s The Boss, the later years.
This is Rory and Jess’ first encounter since Dean dumped Rory at the dance marathon. They are both too shy to say more than a few words to each other in front of Lorelai and Luke, which feels true to life.
