Rory is honored when Emily and Richard give a party to introduce her to their Yale alumni friends, but it soon becomes obvious that their ulterior motive is to find her a suitable husband.

When Jason reveals that he is no longer in business with Richard, Lorelai has an ugly confrontation with her father about his treatment of Jason.

Meanwhile, Luke tells Lorelai that he and Nicole are getting a divorce.

Rory offers to help Logan (recurring guest star MATT CZUCHRY) write an article for the Yale Daily, but she is disappointed when he doesn't invite her to be his date at a book-signing party hosted by his father.

Meanwhile, Emily warns Christopher (recurring guest star DAVID SUTCLIFFE) that Lorelai and Luke are getting serious, and he had better do something quickly if he hopes to end up with Lorelai.
