S3, E8: Today is Bambi's wedding day. But first Belle has an appointment with favourite regular, David, who reveals his own fetish and Belle is more than happy to oblige. After the booking, Belle goes to pick up Duncan but he tells her he can't make the wedding. Belle bargains with Duncan, convincing him to come to the wedding in return for a cracking final chapter of her book. Bambi is distraught to see Duncan at her wedding, and just before the ceremony she cracks and tells Belle everything. Duncan was her client. Belle confronts Duncan. He can't understand why she's upset, she sleeps with other people too. Belle tells him its different, it's her job. That night Belle decides to write her final chapter on Duncan, the serial prostitute user. Knowing that she doesn't want Duncan to profit from her book, Belle emails the chapter to the entire publishing house. There's no way Duncan will publish the book now.
