Booth (David Boreanaz, left), Brennan (Emily Deschanel, center), and Daisy (Carla Gallo, right) said goodbye to Sweets (John Francis Daley, not pictured) in "Bones" Season 10, episode 2. Fox

“Bones” returned Thursday night, in the aftermath of the death of Sweets (John Francis Daley) in the premiere of the Fox series. In the new episode, “The Lance to the Heart,” it would take a clue from the grave from the fan favorite character to finally solve the conspiracy.

The episode began with Booth (David Boreanaz) and Brennan (Emily Deschanel) still struggling with Sweets’ death. Booth was particularly emotional, calling Sweets “family.”

Meanwhile, at the Jeffersonian Institute, Brennan’s team was hard at work trying to solve the case. Examining Sweets’ remains, they found fibers from the carpet of a car that led Booth to the dead body of Sweets’ assailant (Sweets shot him before he was killed). Agent Aubrey (John Boyd) recognized the man as an FBI agent, Kenneth Emory, further proof of the conspiracy.

When the Jeffersonian team examined the killer’s body, they found that the killer didn’t die from Sweets' gunshot wound. Someone else had finished him off to silence him and took the documents he stole from Sweets.

Booth became frustrated when he was unable to get a warrant to bring in Sanderson (Sam Anderson) and Brennan found him with newly bought guns planning to take justice into his own hands. After an emotional argument, she convinced him to come to his senses and find his moral compass.

Booth revisited the FBI agent (Rance Howard) whose interrogation was interrupted by Sweets’ death, but this time he wasn’t talking. Someone got to him first.

Back at the lab, Hodgins (T.J. Thyne) and Aubrey trace the conspiracy back to an FBI agent named Desmond Wilson who may have taken J. Edgar Hoover’s files after Hoover’s death. They find an old hideout of Wilson’s and find a wire recording of John F. Kennedy in the Oval office, proving their theory,

However, even with Wilson connecting Hoover and the conspiracy to Sanderson, it was not enough to bring him in for questioning. Then, Brennan found foreign DNA in Harold Cooper (the long-dead EPA official at the origin of the conspiracy) belonging to Glenn Durant (J.D. McCullum), the ER doctor from the last episode who claimed to have been blackmailed as well. It turned out Durant was Wilson’s stepson and was behind the conspiracy the whole time.

Even with the DNA evidence, Booth and Brennan need to find the files Sweets had to prevent Durant from blackmailing his way out of any legal consequences. Luckily, Sweets’ notes from right before his death led Brennan and Booth to Durant’s files in J. Edgar Hoover’s office at the Jeffersonian Institute. With the files in hand, the conspiracy was finally over.

With the case in hand, the only thing left to do was to say goodbye to Sweets. Booth, Breenan, Daisy (Carla Gallo) and the rest of the team gathered to say farewell, with Brennan making an emotional speech and Booth starting a group singalong of “Coconut” (Sweets’ favorite song) as they spread his ashes.
