Continuity mistake: When Aunt Gwen is talking to Dawson and Joey in the store, just after she says, "General all around cuddliness between the two of you"; Joey is facing her and Dawson is turned the other way, with his back to her. But the next shot of Dawson is a close-up, and he is suddenly facing Aunt Gwen as he says, "OK, I'll tell you the long soap opera short". The transition was too fast to be realistic, or to have given Dawson enough time to turn completely around to face Aunt Gwen.
Continuity mistake: This episode shows a full day's events repeatedly in 4 separate segments, and it appears they reused the same scenes and dialogues. But there are noticable differences between Act 3 and Act 4. At the end of Act 3, when Dawson confronts Joey and Pacey about their relationship; he says to William and Andie, "Better yet, ask Joey. Ask her how long [she's] been lying to me and to you." During this same scene in Act 4, Dawsons varies it slightly: "Better yet, Ask Joey. Ask her how long [the two of them] have been lying to you and to me." He also switches 'you and me' interchangeably. Act 3, Dawson further says, "Go ahead ask them, because I can't [stand to look at them]." But in Act 4, he changes it to "Go ahead ask them, because I can't [even stand to look at them anymore]." The way these two scenes were shot varies also. During Act 3, when Dawson is finished talking he storms back into his house, and makes it inside the inner front door alone. But in Act 4, Dawson starts running back into his house with Joey following close behind him, so that she is in the frame when he reaches the inner front door.
Continuity mistake: When Joey meets Dawson before The Anti-Prom, he loans her his mother's diamond earrings. Just as Bessie says "Put them on, and then I'll get one more picture"; there is a close-up of Joey as she puts an earring in her right ear. It appears that she has just started putting the earrings on; but then she turns to face forward for the photo with Dawson, and you can see both earrings already on her ears. Joey started putting the right earring in just after Dawson told her to put the earrings on, so how did the left ear get done?
Continuity mistake: At the very end of the episode, when Joey and Pacey are sailing out into the sunset the sky keeps changing between shots. When they are first setting off, it's earlier in the day with bright sun and a cloudless sky. The sun appears at a high angle. The next shot, as they sail further the sky is suddenly full of clouds and it's almost sunset, with the sun lower in the sky. The final shot after that, the sky is still cloudy and in sunset hues as the sun appears just over the horizon about to set. Obviously these shots were taken at different times of the day, although they appear to be right after each other in the show.
Coming Home - S4-E1
Continuity mistake: When Joey and Pacey are on the boat Coming Home, look closely at Pacey's hair under the cap he is wearing. It is longer/thicker hair, and appears to be layered somewhat on the sides and back of the neck. A little later when Joey and Pacey have docked in Capeside and are getting off the boat, Pacey's hair is suddenly cut very short/close to the head, and does not look like it did under the cap on the boat. (00:00:50 - 00:05:05)
Coming Home - S4-E1
Continuity mistake: Gram's kitchen in previous Seasons had orange walls, and the cabinets were painted with avocado green and orange centers. (Except for the Pilot Presentation, where the cabinets were painted all green). However, in this scene the walls are still orange but the cabinets have been suddenly changed to avocado green and yellow centers. (00:15:35)
Coming Home - S4-E1

Falling Down - S4-E2
Continuity mistake: At the end of the episode, when Pacey is telling Joey about his school problems; her hair changes dramatically between shots. Just as she says, "Whatever it takes, we're gonna fix it", her hair is blown back off her right shoulder, away from her face with only the hair ends resting on her shoulder. The next shot of Joey, as she says, "I'm not going anywhere without you", her hair is suddenly down in front of her right shoulder, and close to her face again. When Pacey asks her, "Joey?" and she replies, "Yeah?", her hair is still fully down by her face on the right side, in front of her right shoulder. But then the next shot of Joey when she says, "I'm not that much smarter, Pace", her hair is suddenly swept far back off her right shoulder, away from her face with the hair ends resting on her shoulder again. It looks like they filmed this scene two different ways, and edited it together.
Future Tense - S4-E4
Continuity mistake: During this episode, Jack injures his left shoulder playing football and has to wear a sling the entire time. Every single time Jack is shown, he is wearing a blue sling on his left arm, with the supporting strap across his right shoulder (to provide diagonal support), except once. During the party scene when Jack is talking to Dawson - the blue sling is suddenly over his right arm, with the supporting strap across his left shoulder. This scene was actually shot with the sling on the correct arm, but was "flipped" to make it fit with the direction of the next scene to follow. (00:29:45 - 00:33:40)

A Family Way - S4-E5
Continuity mistake: When Dawson is coming down the stairs to talk to his parents in the living room, there is a shot of Gail and Mitch on the couch together. Gail is sitting in such a way that her legs are draped over Mitch's legs, and her right leg is specifically hanging over his right leg touching it. But in the next shot, they show Gail and Mitch from the other side of the couch; and suddenly she is sitting with her legs up, bent at the knees and Mitch has his right leg up. There wasn't enough time between shots for anyone to move.
Continuity mistake: When Andie and Jen are sitting on the swings talking, Andie's blue sweater keeps moving between shots - sometimes it sits off the shoulder, and sometimes it covers her shoulder.
Continuity mistake: The red Harvard sweater Andie is wearing disappears between shots.
Suggested correction: Actually, it shows her taking it off and continuing to talk to Jack.
Continuity mistake: In the scene where Jack is fired Jen is limping. She doesn't have the limp in any other scene and never hurts herself, it comes from nowhere and then disappears.
Continuity mistake: When Jen and Jack are talking in her room, Jack asks "Have you finished your applications yet?" Jen is rubbing her hands together in front of her. But the next shot, suddenly Jen's arms are stretched back behind her. Too sudden to be a realistic transition.
