Audio problem: During Paul Stupin's narrative of this episode, he talks about the scene when Dawson first arrives to pick Joey up for their first date. Only Paul accidently mentions that this scene played on another, previous date they had at the end of Season 1 which ended in disarray, and Joey storming away from the theater. There was no date like that at the end of Season 1; he is apparently confusing that memory with the current scene being shown on screen, which is the actual date. (00:25:35)
Audio problem: In the scene in the pharmacy, when Pacey says "20 milligrams", his mouth doesn't move. (00:13:05)
Audio problem: When Abbie is trying to get Pacey's signature and says, "I'm collecting signatures," the movement of her lips doesn't match the speech. (00:15:05)
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.
