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.

As Lorelai and Max grow closer, Rory begins to get attached to the idea of Max in their lives, which freaks Lorelai out; Sookie and Lorelai have a frank talk about relationships; Lorelai tries to ease out of her relationship with Max during Parent's Day at Chilton, but ends up passionately kissing him in his classroom just as Paris walks by; stung by the details in the newspapers about her parents' messy divorce, Paris tells everyone in the lunchroom about Max and Lorelai to deflect gossip away from her and towards Rory; Rory confronts Paris, gets an apology, and offers a sympathetic ear, which is grudgingly accepted; Sookie asks Jackson out on a date and he accepts.
