All or Nothing

Samantha throws a self-congratulatory soiree at her new apartment where she tries to convince the girls that they have it all -- great friends, good jobs, and plenty of sex. Carrie tries to play along, but her fling with Big eats away at her. Deciding she just can't hold it in anymore, Carrie reveals her scarlet letter to Samantha in private. Carrie wonders if she's trying to have it all: the reliable, committed Aidan, and the wild, exciting Mr. Big. Meanwhile, Samantha, who has long thought she did have it all, comes down with a bad case of the flu, and learns all the men in her life are unwilling to take care of her when she needs them. On the Charlotte front, Trey lays down a pre-nuptial agreement which has Charlotte worth a measly half a mill. On Miranda's advice, Charlotte plays hardball with Trey's mother Bunny and successfully negotiates for a million. Meanwhile Miranda meets her first man post-Steve. George is a cute yuppie from out of town who turns Miranda onto the wonders of phone sex. But Miranda becomes suspicious of George's dexterity over the phone and dumps him when she realizes he's phone-sexing other women too. Carrie knows all about playing on more than one field too. While Aidan is away on a business trip, she hooks up with Big in her apartment again. He tells Carrie he's leaving Natasha, but Carrie tells him not to. When Aidan returns, he sense something is up with Carrie and asks if she's been cheating -- on her pledge to quit smoking. Carrie confesses she's been cheating, and reaffirms her vow to quit.
