Episode 43 of "Gilmore girls"
s02e22 I Can't Get Started

Sookie's wedding draws near, and both bride and groom are getting frazzled, to say nothing of Michel, who Lorelai has placed in charge of the preparations at the Inn. Lorelai finally relents and goes into the diner, where she apologizes profusely to Luke, who is polite, but cool and somewhat remote. Christopher comes to town for the removal of Rory's cast and decides to stay for Sookie's wedding. After he confesses that his relationship with Sherrie is over, he and Lorelai rekindle their relationship, much to the delight of both Rory and Emily. Their reunion is cut short when Sherrie telephones Christopher to tell him she's pregnant, and Christopher returns to Boston, leaving Lorelai devastated. Paris is running for student body president. She's commissioned Madeline and Louise to poll the student body and is shocked to find that even though she's overwhelmingly considered to be the most competent candidate, she'll probably lose the election because she's also the least liked candidate. Frantic, she pleads with Rory to run as her vice president because Rory is so well liked. Dismayed at the thought of being in politics, rather than writing about it, and having to spend six weeks in Washington, D.C. at a summer leadership conference with Paris if they win, Rory refuses at first, but finally relents when Paris reminds her that this just might be the thing that gives her the edge to get into Harvard. Having overcome the likeability hurdle, Geller and Gilmore win the race. Jess returns to Stars Hollow and asks Luke if he can stay. After overcoming his shock and vowing that things will be different this time around, Luke agrees. Jess goes off in search of Rory, ignoring Luke's pleas to leave her alone. When Rory sees him in the Inn's gardens waiting for her, she rushes to him. Surprised, flustered and happy to see him, she impulsively gives him a passionate kiss, and then immediately runs off as the wedding begins. Right before they go down the aisle, she tells Lorelai that she's decided to go to the leadership conference in Washington, unaware that she will be leaving Lorelai alone now that Christopher has returned to Boston.
