RORY: Can we go for a weekend [to stay with Richard and Emily]?
LORELAI: We’ll see how much Valium Auntie Sookie can lend Mommy, okay?
A possible confirmation that it was Valium that Sookie gave Lorelai when she hurt her back on the night of Rory’s dance.
It also confirms that Lorelai and Rory aren’t a “democracy”, as she told her daughter in the first episode. Here Rory wants to spend a weekend with her grandparents in Martha’s Vineyard, and they never go because Lorelai doesn’t want to. Rory could have gone by herself, but Lorelai doesn’t facilitate or encourage that either. Rory probably could have forced Lorelai, but if she did that she wouldn’t have been Rory (and she and Lorelai would never have had the close bond they valued so highly).
