At the start when Harry is talking at the town meeting - the frontal shoots show his hat sitting on the top ledge of the lecture stand, but in the shoots from behind the hat is sitting on the shelf part of the lecture stand.
When Lorelai and Max are standing on the porch of Lorelai's house debating on going in together, there is a snowflake on Lorelai's hat that is present in some shots showing the back of her head, and absent in others.
When Lorelai is talking on the phone to Emily and Rory the objects in front of her on the desk change.
Rory finds a photo album that includes pictures of Lorelai as a baby. In a future episode it is said that Lorelai destroyed all the photos of herself as a baby because Emily kept telling her she had a big head.
When Rory returns from being stranded overnight in Hartford, she comes up the walk and meets Lorelei on the porch. Although it's snowing significantly in the background, there is not a single flake of snow on Rory's hair, jacket, or backpack, and her hair is completely dry.
When Rory and Lorelai are at the town hall in the beginning, they appear to be eating hot dogs...but the hot dogs are missing from the buns.
When Rory returns from Hartford and is standing on the porch talking to Lorelei, as the camera pans to Rory, a crew member is visible behind the Jeep and quickly ducks behind a bush.
At the beginning of the episode, in Max's voicemail message to Lorelei, he says that he thinks of her every time he passes the Stars Hollow sign on the road, indicating that he knows she lives there. However, later when he runs into Lorelei in Stars Hollow after his car has broken down, Max seems stunned and surprised that Lorelei should appear. If he knew that Lorelei lived in the town, it shouldn't be that surprising to see her there at night.
In the previous episode, Lane learned from Todd that Dean is deathly allergic to walnuts. However, in this episode, Rory brings Dean a batch of Rocky Road Cookies, which traditionally are made with walnuts.
