4x22 - Gilmore Girls

Momentous changes are in the air as: the Dragonfly Inn approaches opening day by having a shakedown weekend; Rory and Dean take a major step forward in their relationship, to Lorelai's dismay; Emily and Richard admit that they're separated; Kirk decides to let Lulu in on the deep, dark secret of his night terrors; Jason appears at the Inn to plead his case with Lorelai, to no avail; Luke answers Lorelai's question about the status of their relationship when he makes it passionately clear to Lorelai that they're dating, to which she enthusiastically agrees.
