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. This scene was actually shot with the sling on the correct arm, but was "flipped" to make it fit with the direction of the next scene to follow. (00:29:45 - 00:33:40)
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. (00:00:50 - 00:05:05)
Revealing mistake: In the first scene, Pacey says something like see I think we should probably drop anchor here, have a bite to eat (and other things)... As he's walking around the boat, the camera shifts over and you can see two ropes that indicate the boat is already anchored or docked to something.
