In the previous episode of Bones
, we watched in breathless disbelief as Brennan shared soothing memories with her injured father at his bedside, then felt him slip away and out of her life forever. This episode, titled "The Final Chapter: The Grief and the Girl," takes us through the stages of grief experienced by Brennan, Booth and their team as they pursue a killer of another grieving woman. Sarah Abbott was in Newfoundland looking for a connection to her beloved grandmother when she was shot, pushed off a cliff and left to drift off among the waves. Who did it and why are the mysteries put before the Jeffersonian in this installment.
Adding to the emotional pull of this Bones episode is the brief return of Brennan's ex-lover, ex FBI Agent Tim "Sully" Sullivan. We are led to believe Sully's appearance on the scene is a threat to the Booth marriage simply because Brennan seeks some time on her own, but the idea of a threat is ridiculous. "Grief mixes us up," Sully mentions, summing up what all those who have been through it know to be painfully true. Rather than endangering Brennan and Booth's union, Sully's visit confirms what has been true from the beginning and remains true today: it was and always will be Booth for Brennan, no matter how you slice it.
