LORELAI: We have arrived.
RORY: Arrived where? [looks up] Aw, you are without shame.
Somehow Lorelai has led Rory all the way to Sookie’s house without Rory having the slightest idea where they are going. This is even less believable than the time Lorelai took her right to the very gates of Harvard before Rory suspected where they were. How can Rory not remember where Sookie lives?
Once again, we see that Sookie seems to live a long walk from Lorelai’s house, yet somehow it is too close to get in the car and drive to it. Rory says they are in the opposite direction to the business district, and even wonders if they are walking to the next town, suggesting that Sookie lives on the outskirts of Stars Hollow. Yet the area doesn’t look any more rural than Lorelai and Rory’s street – which makes sense, because in real life, Sookie’s house was right next to Lorelai’s!
Lorelai cannot go to the diner for breakfast, because she and Luke are still in a fight over Jess. The show doesn’t make it clear whether Lorelai arranged in advance to have breakfast at Sookie’s, or if they have turned up unannounced first thing in the morning expecting to be fed (which would not be out of character). Either way, Sookie is delighted to have extra people to cook for.
