Rory has got back with Dean! Lorelai has had a proposal from Max! Their dating lives converge while both are at their peak, and all is joy, all is light, all is love. The promise of Stars Hollow is fulfilled, and lovers are reunited at last.
This is an oddly complete resolution to a season, which ties everything up into a neat package and gives a fairy tale happy ending to both our protagonists. The reason is that they were not sure if Gilmore Girls would be renewed for another season, and if if this was to be last episode ever, they needed it to also be a possible finale of the show. Of course the show was renewed, and from then on season finales tended to end on cliffhangers, leaving many questions unanswered.
