Luke Can See Her Face - S4-E20
Continuity mistake: In this episode, Lorelai tells Luke that she needs to tell the plumber that rooms 10, 12, and 15 have no water pressure, but earlier in this season when she gives the presentation at the town meeting about the Inn to get her permits approved, she says that the inn will only have ten rooms. It is also mentioned in the last episode of the season when Lorelai puts her parents in room 12. (00:04:10)
Chosen answer: Lorelai and Christopher get married impulsively in Paris but they get divorced shortly after returning home. I don't know the exact number of days or weeks but they definitely weren't married for more than a couple of months.
