Continuity mistake: When Carrie is reading the magazine and Aiden punches a hole through her wall, the hole looks to be about 4 feet from the corner of the wall. But after Carrie gets up and runs into the other apartment to confront Aiden, the hole in the other side of the wall is suddenly about 8 feet from the same corner, much further away. (00:12:55)
Revealing mistake: When Aidan and Carrie shower, some sort of screen or towel briefly appears by their waists to add for some privacy and avoid their private body parts (or any garment covering them) being exposed.
Continuity mistake: After the sonogram, while Carrie and Miranda walk, bystanders stare at the filming, check the old lady with a pink T-shirt on the right, bending her neck, and the woman with a cell phone on the left.
Continuity mistake: In the shower, Aidan's slick hair swaps to messed up in a split second. Water couldn't have done it and neither could he, for his hands were busy soaping his body.
Continuity mistake: When Carrie tells Aidan to stop hammering the wall he has dust on his T-shirt, which magically disappears in subsequent shots. After Carrie confesses, dust reappears.
Continuity mistake: At the ball, Richard takes a sip with his right hand, but from a different angle it's his left.
Continuity mistake: When Carrie and Miranda arrive at the wedding dress store two Caucasian women stand on the right, behind them. Then they are suddenly on the left. Half a second later, two Afro-American women have taken their place.
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.
