Star-Crossed Lovers and Other Strangers - S1-E16
Visible crew/equipment: When Rory asks Lorelai to call Emily to get her out of Friday night dinner so she can celebrate her and Dean's 3-month anniversary, a boom mic drops into the shot as Lorelai stands to get the phone. (00:07:05)
Trivia: In some episodes, Rory speaks Spanish (e.g when she is talking to her grandmother's maid). She speaks very poorly, typical "school-Spanish". This is just acting; Spanish is actually Alexis Bledel's first language. Her mother is from Mexico and her father is from Argentina.
Question: In terms of days, weeks, months, etc., how long were Lorelai and Christopher married in season seven?
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.
