Continuity mistake: During this episode, Jack injures his left shoulder playing football and has to wear a sling the entire time. Every single time Jack is shown, he is wearing a blue sling on his left arm, with the supporting strap across his right shoulder (to provide diagonal support), except once. During the party scene when Jack is talking to Dawson - the blue sling is suddenly over his right arm, with the supporting strap across his left shoulder.
Continuity mistake: When Joey and Pacey are on the boat coming home, look closely at Pacey's hair under the cap he is wearing. It is longer/thicker hair, and appears to be layered somewhat on the sides and back of the neck. A little later when Joey and Pacey have docked in Capeside and are getting off the boat, Pacey's hair is suddenly cut very short/close to the head, and does not look like it did under the cap on the boat.
