Plot hole: At the end of the episode, Dawson is seated in the kitchen talking to Pacey in a normally loud voice. At the same time, Joey and Charlie are awake and talking in the pup tent in the living room, very close to the kitchen. Later in the Season we learn that Joey had no idea Dawson had driven down to Florida to see her, as apparently he left without seeing or talking to her. But being in such close proximity that morning; there is no way Joey would not have been able to hear Dawson's voice as he talked with Pacey. The living room was close enough to the kitchen, so it doesn't make sense that Joey wouldn't have known Dawson was there and if she did-she would have gone to talk to him.
Plot hole: When Chris arrives at the beach house, and invites everyone to the MTV concert a few blocks away; he tells them to follow him there implying that he can get them in free with his 'clout' as a movie star. But later during the first song, Joey and Charlie arrive walking up the stairs from the beach apparently just coming from the beach house. They walk right in to the concert area - no problem. But how would they get in without Chris? They didn't have tickets, and Chris wasn't with them to usher them in. It wasn't likely an event open to the entire general public; as it would be too crowded, and not just the younger people MTV audience for TV.
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.

Continuity mistake: At the end of the episode, Joey and Charlie are talking in the pup tent in the living room in the morning. As Charlie says, "I must have lost my touch." Joey is facing him with her hair hanging in front of her left ear and down around her face. But the next shot of Joey as she says "I don't think so"; suddenly her hair is tucked behind her left ear and away from her face. There was no movement of her hand to touch her hair in between shots.
