High Anxiety - S5-E6
Continuity mistake: When Joey is talking to Pacey at the boat party, she turns to face him. At this point, her hair is behind her shoulder on the left but the wind blows it in front of her right shoulder. Her hair is in front of her right shoulder during this entire shot. But in the next shot, she is suddenly facing Pacey square on to the camera, and her hair is now back behind both shoulders. The transition is almost instantaneous, so it isn't realistic that her hair would suddenly move from in front of her right shoulder to behind it that quickly without her touching it. (00:28:05)
High Anxiety - S5-E6
Continuity mistake: When Charlie's two girlfriends play along in his dorm room, their positions change back and forth from close together to about a foot apart between shots. (00:24:30 - 00:25:00)
Answer: It's the same apartment Joey had in NYC. Comparing it to the beginning of the Finale; you can tell it's exactly the same location, furnishings, Plasma TV etc. Apparently Chris was only living with her at HER apartment, and now Pacey has taken his place at the end. I guess this implies Pacey successfully started his own restaurant business in NYC as he had dreamed, to be with Joey.
