Continuity mistake: Gram's kitchen in previous Seasons had orange walls, and the cabinets were painted with avocado green and orange centers. (Except for the Pilot Presentation, where the cabinets were painted all green). However, in this scene the walls are still orange but the cabinets have been suddenly changed to avocado green and yellow centers.
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.
