Trivia: During the scene at the wedding reception, Carrie is wearing her 'Carrie' necklace, which hasn't been on her the entire season. This symbolizes that Carrie feels like she has come back to herself. Also, the 'Carrie' necklace appears and disappears during the entire series in very important and significant ways.
Trivia: During this scene, Samantha throws a cantaloupe through the plate glass door. Carrie is standing in the background at the party, and you can see her suddenly duck and react very strongly to the glass breaking. The reason she did this was because, when the glass door was shattered, the glass fragments flew out a much greater distance than had been expected. All of the actors standing near there, including Sarah Jessica Parker, were taken by surprise.
