Agent Booth is back to the Jeffersonian in not so familiar surroundings as Aubrey looms large over him, according to the latest "Bones" season 11 spoilers.

Meanwhile, there's going to be a shift in the relationship between Cam and Aristoo as she chose her career over her love life.

New "Bones" boss Michael Peterson told TVLine that Aubrey can be very ambitious.

"He has goals, and he's a mover and shaker," he said. "Booth is more of your great foot soldier. Aubrey has ambitions to be a general. So that's going to play out. Right now, it's not heated yet, but we still have the second half of the year to go. So we'll see how contentious that gets between Booth and Aubrey."

The synopsis for "Bones" season 11 offers plenty of spoilers.

"On Brennan and Booth's first official day back at their respective positions at the Jeffersonian and the FBI, things get exciting when remains are found at a fish farm under suspicious conditions, prompting them to investigate," it said. "After it's discovered that someone harvested several of the victim's internal organs before he was dumped in the water, Angela tracks down the seller and buyer of the organs to try to uncover important details in the case."

The storyline for episode 3 added, "Meanwhile, Booth readjusts to his position back at the FBI and discovers Aubrey has taken over his old office; Hodgins pushes Angela to showcase her photography work; and Cam struggles with her decision to choose work over her relationship with Arastoo."

Michael Peterson, previously promised to "shake things up" this season.

"Cam and Arastoo get shaken up in the very beginning," he told The Hollywood Reporter. "There's going to be a shift in Angela's and Hodgins' relationship around episode 10 and we'll see another one for Booth and Brennan later on in the second half of the season. It's not going to be a business as usual season."

"The big thing is the season has to be character-based," he added. "It has to be organic as far as the reason for them to quit and ultimately for them to come back. Not to spoil too much, but by the end of episode two, Booth and Brennan are going to be more or less back at their respective jobs."
