Not since The Sirens of Time ... anyway ... the key element which has been remarked upon script wise is how its designed to underscore that this is a story set in the now, referencing Amy Schumer and John Oliver. But mores to the point, in the middle of Lorelai's bit, Rory dives into her iPhone and searches for information about what the bad smelling plant is, which does feel weird if you've just ended a binge of all seven seasons and the last time you saw these characters Rory's grandpa was trying to find a decent wifi signal in his house by holding his laptop behind a plant, everyone had only just graduated to "burner" mobiles and people still used pagers.
Anyway, the point of me writing this about a coincidence. Rory gets her answer, presumably from the wikipedia: "Corpse flower" and she does this on almost the same day that an example of the species is in a blooming cycle at New York’s botanical garden in the Bronx and sure enough Lorelei's quite correct. People have queued up to see this oddly beautiful monstrosity and The Guardian was there to find out if indeed it does smell like a dead fish:
"“It smells like lettuce when you take it out of the bag,” a woman yelled from the crowd of onlookers in the Enid A Haupt conservatory. “It smells like the aquarium. Like the penguin enclosure,” another added. The odor came in waves as onlookers jostled for the best spot to take photos and selfies with the giant flower. Some left holding their noses."
