Plot hole: During Season 4, at Graduation, Andy informs Jack that she is 'deferring Harvard for a year' and going back to Italy instead, as she is happy there. Therefore, it makes logical sense that we never see Andy's character in all of Season 5, when all the other major characters ended up in Boston together. But it doesn't explain Season 6, when Andy should have been back in Boston attending Harvard University. It isn't likely she would have jeopardised her education and deferred a prestigious college like Harvard for more than a year (they probably wouldn't allow it); and if she was, in fact attending Harvard in Boston during Season 6 and she was such good friends with everyone, surely she would have hung out with them at times! Everyone else did. It doesn't make logical sense that Andy was attending college in Boston along with everyone else that year, but they never saw her at all. And they never explained her absence at all in the scripts. Plus the fact that in the Series Finale, she is at Mass. General in Boston furthering her medical training; implies she did indeed attend Harvard for her undergraduate, Pre-Med education.
Deliberate mistake: Throughout the first episode, Jen's bangs are long in scenes relating to her "Grams" and short in all other scenes. This is because the scenes involving her storyline with Grams was shot much later, after the show was picked up. (00:05:45 - 00:16:15)
Visible crew/equipment: It's morning at Jen's and Grams'. Jen is seated at the kitchen table downstage/far left. Grams is upstage/right at the stove scrambling eggs. Grams crosses downstage to put the eggs in front of Jen and the mic overhead upstage/right peeks out just a tiny bit. Grams crosses back to the stove. Suddenly the microphone - including the rod the mic is on - just drops down almost completely into the frame over Grams' head and is not pulled back up.
Continuity mistake: After Joey finds the visitor Anderson playing a violin on his yacht, they have a back and forth conversation where she hides her work apron behind her back. When the camera angle switches back and forth, her arms are in different positions. (00:14:10)
Other mistake: After Dawson and Jen order "cokes" from Joey at the seaside restaurant, Joey pours their drinks into plastic red cups. She only pours several milliliters of cola into the cups, barely enough for one gulp. (00:29:50)
Continuity mistake: When Pacey drives Joey and Dawson to the market to get party supplies, they leave in broad daylight. It can't be more than a few minutes down the road, being such a small town. Yet as they drive there, the sun is suddenly going down, and when they arrive at the store it's dark and night time. It couldn't have gone from broad daylight to dark night time in that short period of time. It appears to be a very long drive, but it's just the local market.
Plot hole: When Pacey drives them all to the market, he explains that he had to 'steal' the car from his family, and thus doesn't have the keys. He makes Joey stay in the car while they are shopping, because he can't turn off the car. But later, at the end of the episode, Pacey suddenly goes running out of Dawson's house late at night, jumps into the same car and turns keys in the ignition to start it and drive off in a hurry. How would he suddenly have the keys to the car? He drove them all straight to Dawson's house from the market, with the crazy girl - and the car had been there ever since. He had no time to go back home to get the keys; and it isn't likely his father, the town sheriff, would allow his underage son without a legal driver's license, to have the keys.
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)
Continuity mistake: When Joey finds Dawson at Pacey's Pier Party, it is raining heavily. Both Dawson and Joey get soaked and their hair is very wet as they reunite and kiss. At this point, it suddenly stops raining and does not rain again the rest of the time at the pier. But later, when Jen and Abby are talking behind them, both times Dawson and Joey are shown from the rear their hair is noticeably dry, wavy and styled. Later, when Dawson and Joey are talking again before she goes home, their hair is once again very wet and combed flat against their heads. Also, neither Jen or Abby's hair appeared wet at all during the party.
Continuity mistake: When Pacey is at Andie's house waiting for their date, he picks up a family photo of the entire McPhee family. There is a close-up of this photo, and you can see all family members including Andie's dead brother, Tim, and her father. Look closely at the man representing her father in the photo. It is not David Dukes, the actor who later plays her father. Apparently this scene was shot/photo made before David Dukes was available. (00:26:05)
Plot hole: Jack and Joey are desperate to get the tank pump fixed so they can put the lobsters back in. However, once the customer tells them how to fix it, they then stop for a chat, check his table for tips, read a poem, share a moment, and start cleaning counters - with no attempt to re-house the lobsters.
Continuity mistake: When Pacey is at Andie's house waiting for their date, he picks up a family photo of the entire McPhee family. There is a close-up of this photo, and you can see all family members including Andie's dead brother, Tim, and her father. In addition to the Father in the photo not being actor David Dukes, there is a completely different person in the photo representing Tim, the dead brother, than the actor who portrayed him in Andie's delusions later in the season. The person in the photo is sandy blond haired, and the actor who later portrayed him in the show was a different person with very dark hair.
Plot hole: Season 2 picks up with everyone still in Sophomore year, which continues until the end of that Season. So we are presumably well into the Sophomore school year, and yet during this episode there are suddenly elections for the Sophmore President and Vice President. It doesn't make sense they would wait until this far into Sophomore year to be electing officers *for* the Sophomore year! Too much time has passed; normally elections like that would be held at the beginning of the year so the people elected can do their jobs longer, for the entire Sophomore year.
