Downtown Crossing (2) - S5-E15
Plot hole: When Joey suddenly regains consciousness in the ER, she is sitting upright on the end of a hospital bed or gurney. But this doesn't make logical sense, because if she were really unconscious she would be laying down. Yet it's made very clear in that shot, that she is opening her eyes for the first time after fainting and being unconscious.
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.
