In this episode of Bones, Booth and Brennan (along with the rest of the team) work to find out who murdered Sweets. In the process, they also have to deal with their loss and negotiate working with a new FBI agent.

As one might expect, it’s an episode filled with emotion. Booth blames himself for Sweets’ murder, saying that he should have been the one to serve the warrant that got Sweets killed. Booth and Brennan also have to break the news to their little girl that “Uncle Sweets” is gone.

Booth still seems a bit hesitant of Agent Aubrey, but they work together throughout this episode. It won’t be long before they develop a friendship and Aubrey is welcomed as part of the group.

Even though Sweets isn’t actually in this episode, he is very present. Booth even channels Sweets when looking at evidence, saying it is important that they look at it the way Sweets would—through a psychological perspective.

Sweets also had notes and ideas about the conspiracy before he was killed. Thanks to him and his influence on the team at the Jeffersonian, his killer is caught and the conspiracy is finally put to rest. And it was quite the conspiracy, too -- dating back to J. Edgar Hoover.

Once the case is solved, the group can now finally say goodbye to their friend. It’s a small funeral, with just Sweets’ closest friends -- rather, his family. To honor him properly, they spread his ashes overlooking D.C. while singing a song that always put Sweets in good spirits: “Put the Lime in the Coconut.”
