RORY: I’m here all by myself and I’m trying very hard to be calm but I’m starting to feel nauseous, and the hospital has a smell, and there are noises, and those gowns do not stay closed and I’ve seen a lot of butts today! And –
LORELAI: Okay, sweetie, calm down.
RORY: I need you … I need you, I need you here, I need you now. I cannot do this alone. I need my Mommy, and dammit, I don’t care who knows it!
Rory has been consistently shown as needing Lorelai’s help to handle even small personal crises, but this time, surely no one can blame her for desperately calling her mother for help. She’s a young adult thrown in the deep end, and must be both hungry and exhausted by now.
Even now, she probably wouldn’t have called Lorelai, except that that she was told that she might well be accompanying Sherry, a woman she barely knows, in order to help her through the birth itself. Rory notoriously doesn’t cope well with “icky” things – even planting bulbs in the garden is gross for her – so you can imagine the trauma witnessing a birth would cause.
