Spur-of-the-moment decisions can lead to some of the most rewarding life changes, or at least that's what Kate learns from interviewing Wendy, a confessor who traded a career for a family after falling in love with her one night stand.
Spurred on by her own marital problems with Gavin and a disastrous attempt at couples' therapy, Jodi wonders if Kate is really ready to marry David. Jodi loves Gavin, but marriage is a bitch. That must explain why David can't make a decision on anything except taking a phone call from Araminta in the middle of their make-out session.
Inspired by Wendy's epiphany that saying yes to spontaneity can lead to a fulfilling life, Kate realizes the most important thing about getting married is the person she's with. As a result, she surprises David, arranging to meet him at City Hall.
