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)
Audio problem: In the scene in the pharmacy, when Pacey says "20 milligrams", his mouth doesn't move. (00:13:05)
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: At the end of the episode when Pacey and Joey are paying for their items, Pacey launches into a philosophical speech. The cashier has asked him whether 'they found everything they were looking for' and he answers no, but they found what they needed, which was even more important. He then elaborates, explaining that 'if you found everything you needed that day, what would be the point of doing it all over again the next day'. But Joshua Jackson apparently messed up his dialogue, because the point he was making was that they didn't find everything they were looking for, not what they needed. He was making the point that they did find everything they needed, so it would be contradictory to then explain that there was no point in finding everything you need. He meant to say 'if you found everything you wanted (versus needed), what would be the point of doing it all over again the next day'. Oops.
Lovelines (aka The Eddie) - S6-E19
Audio problem: When Jen is hosting the LoveLines event, she tells CJ that he is supposed to field the calls and not ask questions. But she appears to fumble her dialogue, and actually says, "You field, they ask, field, ask, field, ask," etc. She inadvertently gets it backwards, because in reality the question would come first and then CJ would field the question to the rest of the show. (00:14:05)
Audio problem: When Dawson's father hands the baby to Joey, so he can take a picture of her and Gretchen before the Prom, you can hear a noticable "Ahhhhhh" in a female voice from the background, that sounds very much like Dawson's mother. But this wouldn't make sense, as Gail had just gone off to find her shears and cut roses for the corsages.
Separate Ways (Worlds Apart) - S5-E20
Audio problem: At the bar, the singer's lip movements do not match the song.
100 Light Years From Home - S5-E19
Audio problem: When the band M to M is performing at the MTV concert, the girls start singing a song that requires a very tight harmony. During the entire time they are singing together, the camera shows close-ups of both girls. But at one point, they show the second girl with the guitar simply smiling and looking up. She is *not* singing at all, yet the song continues to have both their voices in the harmony. The rest of the bandmembers are male, and the harmony was formed by the two female lead singers. (00:13:30)
Audio problem: When Dawson goes into his bedroom to talk to Jen, he tells her that he had an entire "impassionate" speech to tell her. It sounds like he fumbled his dialogue, and meant to say either "impassioned" or "passionate," but got the words mixed up in his head and ended up blending them together. (00:33:40)
All Good Things... (1) - S6-E23
Audio problem: When Doug pulls Jack over at the start, listen closely as Jack says "It's a deserted road". You can hear the sound of a car passing in the background. Not very deserted then. (00:06:40)
Audio problem: When Charlie is trying to hit on Joey at the College Bar, she makes fun of him referring to him as the "Bass Player to take home to Mom" or something similar. However, when you see and hear Charlie playing in the band during that episode, it sounds like he is specifically playing either electric lead or electric rhythm or both, *not* bass.
...Must Come to an End (2) - S6-E24
Audio problem: During the narrative for the Season Finale, second half, Paul Stupin the Executive Producer is talking about Joey and Pacey's romance in the show. He mentions that they went on an "epic journey on a sailboat all over the world." He's a bit mistaken; as when Joey and Pacey went sailing at the end of Season 3, they sailed from Massachussetts down the Eastern Coast to Florida and back again. It was hardly "all over the world". (01:04:45)
After Hours - S5-E21
Audio problem: Just after Audrey storms out of Pacey's apartment, after catching him with Alex; Pacey runs after her and they begin arguing in the street. Audrey makes a comment that 'it meant your arms around her, and HER tongue down YOUR throat' referring to The Kiss between Pacey and Alex. But then Pacey counters with 'well actually, it was HER tongue down MY throat' in sort of a comic way, as if he was correcting a backwards situation. But Audrey had just said the same thing! One of the Actors messed up their lines, probably Busy Phillips since Joshua Jackson seemed to have his lines correctly.
...Must Come to an End (2) - S6-E24
Audio problem: During the Season Finale Narrative, second half- Creator Kevin Williamson mentions that The Kiss between Doug and Jack on the beach was "the second gay kiss in the show". He's a bit mistaken, as this was actually the 4th gay kiss in the entire series. Jack kissed Ethan in Season 3, Toby in Season 4, David in Season 6, and Doug in the Season Finale. (01:36:00)
Audio problem: When Jen is talking to Jack at the Helpline Office, she jokingly tells him that he is too young to be likely to "haunt them with your sad, single self." She appears to fumble her dialogue, however, and you can hear her almost switch the words around and say "single, sad self." She catches herself, and says 'sad' first instead. (00:35:50)
A Weekend in the Country - S3-E12
Audio problem: During the scene where the group (including Mr Fricke) are all having breakfast together, Pacey says 'this is for you, Mr Fricke' and hands the B&B critic a plate. A few moments later, when Joey is in the kitchen area talking to Bessie (away from the group in the dining area), the exact same dialogue can be heard from Pacey as background noise to Joey and Bessie's conversation. The laughter and general chatter is also the same, showing that the entire audio was lifted from the breakfast table scene and placed over the kitchen conversation scene.
Answer: It's only explained once in the series. Jack says to Andie "I tried to start kindergarten without you", meaning Andie was smart enough to start school early.
