When Lorelai arrives for Friday night dinner (the one where the Historical Society is showing people around), her parents and Rory are not only already at the dining table, they've also started dinner without Lorelai. Normally, dinner is preceded by drinks. Either Lorelai is very late in which case it's strange that her parents don't say anything about it and Lorelai doesn't apologize. Or this is very out of character especially for Emily, who usually insists on them all starting dinner together. Even with all the people in the house, it's strange.
