Revealing mistake: When Carrie and Berger are talking on the grass, Berger suddenly gets up to leave. He grabs his jacket which Carrie is sitting on, knocking her over. As she falls back, you can see her quickly pull the front of her shirt over herself to make sure it covers her pregnant belly. Also, as Carrie starts to get up, there is a point where her shirt falls forward, and you can see Sarah Jessica Parker's pregnant bulge from the side. (00:18:35)
Revealing mistake: During this scene, Samantha throws a cantaloupe through the window. As Sarah Jessica Parker reacts to the incident, you can see her very pregnant belly from the side, especially as she bends over. According to the commentary, she was about 7 months pregnant at the time. (00:20:15)
Continuity mistake: During brunch outside, Miranda's bite on her muffin changes shape between the side and the front shot.
Continuity mistake: During the girls' chit-chat, the amount of ice tea in Miranda's glass suddenly decreases between shots.
Continuity mistake: While eating outside with Miranda and her baby, Carrie takes a french fry to her mouth, but her hand suddenly disappears in the following shot.
Continuity mistake: When Carrie bumps into the dogs, the dog walker is sometimes on the middle of the streets, others next to the building, others crouching and others standing still. No continuity. (00:01:05)
Continuity mistake: Charlotte asks Carrie how many outfits has she bought, and takes her left arm to her hair. Half a second later her arm is lowered. (00:01:30 - 00:13:29)
Visible crew/equipment: When Carrie is entering the NYSE, she has to go through a metal screener. When the security guards are using the wands on her, she spreads her arms, and you can then see some sort of horizontal line or wire sticking out from under her dress, around the waist. There also appears to be something above the wire, showing through the material. She seems to be wearing some sort of contraption under her dress, and when she moves, the entire object moves loosely. Possibly this is her microphone and attached wire? (00:02:40)
Continuity mistake: Charlotte drinks from her glass but her arm is lowered a shot later. (00:05:45)
Continuity mistake: When Steve is wiping Miranda's face with the baby wipes, there are still a few smudges on her forehead. But after she chases him across the room and back again, suddenly the smudges are gone, and her forehead and face are entirely clear of anything. She did not have a chance to wipe her skin at all. (00:06:55)
Continuity mistake: When the girls starts having lunch, Sam's arm is raised then suddenly lowered. (00:12:40)
Plot hole: When Carrie runs into Aiden on the street, he tells her that he 'married another furniture designer'. Although Carrie is happy for him, it doesn't seem likely that she wouldn't have known about this. Steve and Aiden are business partners and close friends, and Miranda is very close to Steve with their baby. Carrie would have undoubtedly heard about Aiden's marriage through the 'friends grapevine' before that, as news that big wouldn't just slip under the radar. Someone would have told her, so it isn't logical that she is just now finding out about Aiden's marriage. (00:25:55)
Plot hole: In this episode Carrie runs into Aidan, who now has what looks to be about a 6 month old baby (Tate). This doesn't seem possible, as Carrie and Aidan would have only broken up about a year ago, and Miranda was around 6 months pregnant when they broke up. Brady is only about 5 months old at this point in the series, leaving Aidan only roughly 8 months to have this baby - but Aidan lay in bed for about a month and then dated Nina Katz for awhile. Timeline just doesn't seem to fit.
Continuity mistake: When Carrie and Berger enter the Lincoln Center there's a man behind Berger smoking. When they enter the place a second later, the man has vanished.
Continuity mistake: When Carrie and Miranda talk while sitting on the bench, a couple suddenly appears behind them.
Continuity mistake: When Miranda dines with Steve her menu is lying on the plate or resting on her bosom, depending on the shot.
Continuity mistake: When Carrie's date splashes vinegar on his sty, the position of his left arm is inconsistent in every single shot.
Visible crew/equipment: When Carrie confesses she bought six outfits for her date, camera and crew are reflected on the glass of Coke.
Continuity mistake: When Charlotte tells Carrie to go on the second date, there's quite an editing chaos with Charlotte's glass: It suddenly appears in her hand without her having picked it up. Then she puts it down but a shot later she is drinking again.
Continuity mistake: During lunch at the diner with the girls, Carrie's straw swaps between pointing in a 3 o'clock direction to an 8 o'clock, back and forth.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
