The latest "Bones" season 11 spoilers revealed that the premiere episode will focus on Booth's (David Boreanaz) disappearance. It was said that a new cast member will join the FBI to help investigate his case.

Spoilers hinted that the premiere episode of "Bones" season 11 will pick up six months after Booth and Brennan (Emily Deschanel) left the Jeffersonian. After solving several cases together, the couple realized that their jobs will make it hard for them to raise a normal family together. They decided to move away and start a new life together.

New reports, however, indicated that Booth has gone missing. Showrunner Michael Peterson said that it was for a "very personal reason."

"It's a family reason. He gets involved in something that's very close to home and is probably the only thing that would pull him away from the tranquil life that he was leading up until that moment," he told Entertainment Weekly.

Meanwhile, fans of "Bones" are also eagerly awaiting the crossover episode with "Sleepy Hollow" airing on Oct. 29. It was said that in the episode, both Booth and Brennan have returned to their old jobs and the team is already back to its usual operation.

"On 'Bones,' the grisly discovery of human remains lead Brennan and Booth on a hunt for clues, during which they encounter Ichabod Crane and Abbie Mills, searching for answers of their own. Realizing that they are after the same evidence, they team up to solve the mystery," read the official synopsis from TV Line.

"Then, immediately following on 'Sleepy Hollow', the intrigue continues as Ichabod's old nemesis is back from the dead. Ichabod and Abbie need advanced forensic help and expertise to stop him and turn to Brennan and Booth to unlock 18th century secrets using 21st century science.
