Dean gives Rory her first kiss; fearful of her mother's disapproval, Rory decides not to tell Lorelai for a little while; Lorelai gets stressed when she hears about the kiss from Mrs. Kim instead of Rory; Rory freaks out at first when Lorelai invites Dean over to watch videos and eat junk food, but ends up having a good time after all.

Chilton hosts a dance which Rory and Dean attend, confirming that they are "boyfriend-girlfriend". Emily sleeps over at Lorelai's the night of the dance to take care of Lorelai's injured back and to see Rory off. Rory and Dean fall asleep accidentally, causing Rory to arrive home at 5 a.m., which pushes Emily to think they had sex. Thus erupts another blow-up between Lorelai and her mother.
