Continuity mistake: When Samantha first puts on the gold necklace in the hotel room, the pendants dangling on the right side are lying over the right lapel of her blouse.

Plot hole: When Charlotte places her ring box in front of Carrie on the table at the restaurant, there is a close-up shot showing that she is still wearing her simple gold wedding band on her right hand. The entire episode has emphasized that it's strange for Charlotte to still be wearing her diamond engagement ring when she is alone, since she is getting a divorce. So why is nothing mentioned about her continuing to wear her gold wedding band? That doesn't seem to be an issue, but wouldn't it be just as strange? (00:26:40)
Plot hole: When Aiden suddenly shows up below Carrie's window the night of their dinner together, she gets up and looks down at him from her apartment. He suddenly starts to run into the building, and at the same time Carrie immediately starts running quickly through her small apartment to get to the front door. It would have only taken Carrie a few seconds to get across her apartment, but Aiden would have had to run up the three or four flights of stairs to reach the front door of Carrie's apartment . That would obviously have taken much longer; yet as soon as Carrie opens the door, Aiden is already there and running into the apartment. (00:25:25)
