In this episode, Emily says that she has no baby pictures of Lorelai, but in the episode "Love & War & Snow" Emily and Richard show Rory a baby picture of Lorelai in the photo album Rory finds.
When Emily is talking with Michel in French, she says she visits Paris every spring. While a couple of episodes earlier on Friday night dinner, she and Richard say they only visit Europe in the fall.
A few minutes in, when Rachel comes into the diner and shows Lorelai the pictures from the festival, she asks her if she wears contacts. Lorelai says no. However, in a previous episode Lorelai was in the kitchen at the inn and said she thought she put one of her contacts in backwards.
When Luke and Lorelai are talking in the store room, the cans on the shelves behind Luke change positions several times throughout the conversation. Also, one of the jars of Grey Poupon behind Lorelai keeps getting rotated between the front and back label.
The photo of The Dragonfly only shows dead trees and leaves. Rachel states she took the photo a couple of days ago. That afternoon, they go to the actual inn. The porch railing is knocked down and the roof is in disrepair.
Just before the scene when Rory and Lorelai are at the cinema, before they enter, you can clearly see Rory, Dean, Lane and Ted on their double date entering the cinema, scene that was cut from a previous episode.
While Rory and Lorelai are in the diner in the beginning of the episode, one of the cameras has a hair on the bottom right of the screen, it shows up twice while at that angle.
When Emily's heel sinks in the mud, it is a very thin heel. The shoes have a much thicker heel when given to Rory to clean.
When Emily starts berating Lorelei after Rory sees her new room, Lorelei say "I missed the checkered flag, when did the argument start"? Checkered flags are used to signify the end of a race, not the start.
After the fight with Emily, Lorelei & Rory go to Luke's. Lorelei sits her purse on the ground as Rachel is talking to her which visibly falls over and makes a loud thud.
When Lorelai talks to Emily at the Independence Inn, a boom mic briefly drops into the shot.
