At the school where the group is sitting in a circle discussing their project, Paris and Louise are having a back and forth. Every time the camera shifts back to Louise her legs are crossed in a different way (left over right, right over left, and so on). This happens about 5 or 6 times.
When Lorelai sits down with Dean to discuss how "clingy" he is with Rory, both Lorelai and Dean's hand positions change between shots, specifically whether their fingers are laced, resting normally on the table or raised in the air.
At their Friday night dinner, Emily says to Richard that she has never started a dinner without him unless he was out of town or seriously ill, but in "Hammers and Veils", Emily is so angry with Lorelai about having found out about her wedding from someone other than her own daughter that she rushes Lorelai and Rory into the house for their Friday night dinner and tells them to start the dinner without Richard because he has an early flight the next morning.
