[Early the next morning, Lorelai and Rory are in Lorelai’s jeep driving through Stars Hollow.]
LORELAI: We’re almost there and nowhere near it. All that matters is we’re going.
RORY: We’re practically gone already.
LORELAI: Look out world.
[They stop at the red light and stare at it, waiting for it to change.]
There have been so many mentions of great American journeys in Gilmore Girls, from On the Road to Huckleberry Finn to Thelma and Louise, that it seems in tune with the show’s theme for Lorelai and Rory to hit the road at some point. Their conversation is even vaguely reminiscent of a famous exchange from On the Road:
““Sal, we gotta go and never stop going ’till we get there.’
‘Where we going, man?’
‘I don’t know but we gotta go.”
That urge towards the journey and not the destination is the same one that is driving Lorelai away from her home.
As luck would have it, before they even leave town, they get stuck at the new traffic light, which is timed to come on even if there is no other traffic on the road, and will stay on until the oldest and feeblest person in Stars Hollow can safely get across the road. It’s symbolic of the way that it will always be difficult for them to leave Stars Hollow, even temporarily. There is something in the town which holds them captive to some extent.
This is the literal “red light on the wedding night” alluded to in the episode’s title, although strictly speaking it isn’t the wedding night, but several days before the wedding. Symbolically though, it means that Lorelai has put a stop to her wedding going ahead.
