The girls get ready for a Saturday night out at an engagement party, but are dismayed when they see the invitation - it announces that the couple has "Two souls, one thought." After the party, Charlotte shows up at Trey's apartment wanting to talk. When she includes "sex life" under their list of problems, Trey tries to convince her otherwise. But instead of being convinced by Trey's passionate advances, Charlotte ends up with an unpleasant surprise on her leg. At the coffee shop, the girls discuss the concept of "soulmates." Afterwards, Samantha spies a hot priest outside a church. The next day, she spends her afternoon masturbating to "her priest." Over drinks, the girls discuss masturbation fantasies, and Charlotte admits that recently she masturbates to only one man - Trey. Samantha takes some canned peas to her priest, but is disappointed when he tells her that his life is about "other joys" than sex. Carrie wonders: "Are soulmates a reality, or a torture device?"

Samantha decides to throw Carrie a "fabulous lite" 35th birthday get-together at Il Cantinori. When all her friends are late, Carrie is left at a table for ten all alone. At the coffee shop, Carrie admits that while she was sitting alone at the table, she felt sad that she was 35 and had no special man in her life. Charlotte suggests that the girls could be each other's soulmates - and men could just be in their lives for fun. Returning home, Carrie spots Big's car. He's brought her red balloons and champagne. They sit in his car and talk about "soulmates."
