The Kids Are Alright (1) - S6-E1
Factual error: When Joey is talking to the Professor, he mentions that her Birthday is the next day. Dawson also helps Joey celebrate her Birthday early at Midnight that night. Clearly this is some time in early Fall, when the Semester first starts at Worthington; probably August or September. But during the Season 5 Finale, Bessie hands Joey her Passport which has Joey's Birthday listed as May 13, 1983. Also, in previous years of the show, Joey's Birthday was never shown to be in the Fall. She didn't even start learning to drive until later in Season 3. (00:07:40)
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.
