Airdate: September 3, 2008 at 8 p.m.

Grayson "Birimbau" Barasa, aka Angela's husband, finally surfaces. He doesn't want to sign the divorce papers, claiming that he still loves Angela. She told him that she now loves Hodgins but Birimbau doesn't want to listen. He reminds her of the night they met and how they both felt in the hope that Angela's love for him comes back. Later, Hodgins meets with Birimbau at a diner to have him sign the papers. Birimbau tells Hodgins that he has been looking for Angela for the past four years and that he even built her a house in Florida so there is no way he will let her go without a fight. Angela and Sweets meet Hodgins and Birimbau outside of the diner. Hodgins and Birimbau start to fight and Sweets joins in on the action before Angela walks off. One of the London folks Brennan and Booth interact with is Inspector Cate Pritchard.
