Everything Put Together Falls Apart - S6-E9
Plot hole: When Pacey first finds Emma in the bathroom cleaning the toilet, she makes a point of mentioning that 'she has band practice in an hour'. But right after they 'strike a deal' and Pacey agrees to her terms for the party, Emma suddenly announces that 'she is off to band practice'. Only a few minutes have passed, so it seems strange Emma would suddenly be going to a band practice that doesn't actually start for another hour.
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.
