Admissions - S4-E17
Plot hole: When Pacey and Joey are unloading the groceries from the car for her party, Pacey makes a remark that he has to go to Joey's garage to get a dolly to haul in the charcoal. But Joey's house doesn't have a garage. During the entire series; there has never been a visible garage on their property, and the large blue truck is always parked out front in the open.
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.
